What Are Problems When Using Solar Street Light with Sensor?

The economic development has made our city construction work more emboldened, and more advanced equipment can be used.Solar street light with sensor have entered our line of view in this context. It has been widely used in many large cities in China. As an energy-saving product that can effectively save energy and protect the environment, we want to make solar street light with sensor better for us,extend its life services.In actual use, also need to pay more attention to these issues.The first is the heat dissipation problem. We all know that solar street light with sensor are generally led light source, so its service life is very long and if you want to improve its service life for a longer time, it is necessary to increase the heat dissipation and constant current of the led lamp.Work harder,effective heat dissipation can help control the temperature of the led tube.The second is the anti-theft problem.Because solar street light with sensor need to be equipped with solar cells and solar panels,this has become the target of theft of criminals. Therefore, in order to be able to use normally, it will not affect the night lighting. During construction, it is necessary to pay attention to effective anti-theft, and the battery can be buried. Under the pedestal of the solar street light with sensor,the cement is poured on it, so that the solar battery can be effectively prevented from being stolen, the economic loss is reduced,and the normal lighting work is not affected. In addition,solar street light with sensor can use lithium battery,the lithium battery has one-third of the weight of the same-power lead-acid gel battery and one-third of the volume. It is even more difficult to be stolen by installing it inside a pole, inside a bracket.The third is to choose the right solar street light with sensor controller. Although the controller is very inconspicuous in the entire solar street light with sensor system, its quality will directly affect the life of the entire street lamp system and the cost of use, so be sure to choose a controller with excellent quality during construction.As a typical example of green lighting equipment, the use of solar street light with sensor is very beneficial to our country and the masses. If you want to fully utilize its long-life advantages, you must add more in construction and pay attention in actual use.

Optical sensors or magnetic sensors for position control?

Optical sensors can be very precise, but they will also be pricey maybe ($75-300) Magnetic sensors can be are accurate as far as on/ off, they are also going to be much cheaper ($20-50) Both types of sensors can be tampered with if that is something you are worrying about but the optical will be harder to tamper the single.

2001elantra,loss of power,especially on up grades.?

you have replaced a few items that would do this. however we need a diagnostic check to see fault codes. using these we can have a better chance of a solution. for example coil pack, plugs,crank sensor wo not do that. map sensor and TP sensor may.. do that. as its sudden cut back and reapplication of power we need to look at ecu inputs. this would seem to be an electrical issue such as loose wire on a connector. accelerating gently up and down by itself is more of an actuator issue. again diagnostic check with a competent technician is best way to get decent fix.

Bad oxygen sensor? or catalytic converter?

a low catalyst efficiency very rarely points to a failing cat or o2 sensor. the fact that it does not get hot enough to work right can be the issue. look for a vacuum leak on that bank or an exhaust leak on that side. either one could lead to that.

Serial sensors and the Yun

I do not have any experience with the Yun so I can not comment on that specifically, but the only problem you will encounter with using SoftwareSerial is that you can only communicate with one device at a time.This means you will have to make a call to listen()before communicating with sensor1. Then when you want to communicate with another sensor, you have to do the same.

What Is the Best Motion Sensor Outdoor Lights on the UK Market?
What Is the Best Motion Sensor Outdoor Lights on the UK Market?
A motion sensor light comes on once it detects motion from a person walking nearby. It's an important part of your home security. It's also a convenient and energy-saving way to light up entryways and garden paths at night. Unlike traditional outdoor lights that stay on all night long, a motion sensor only activates when there is movement. This saves energy. There are different types of motion sensor lights. But they all work on the same principle: detect movement, activate light. You can also have the motion sensor trigger an alarm for extra security. In this buying guide, I will give you some tips on buying the right motion sensor outdoor lights for your home and review the best ones you can buy online in the UK. What to Consider When Buying Motion Sensor Outdoor Lights Passive infrared sensors are the most common. They work by detecting infrared heat given off by the body. If it detects a rapid heat spike from a specific area, the sensor triggers the light. Microwave sensors work by emitting microwave radiation and measure waves reflected off someone moving. They cover a larger area than passive infrared sensors but are more expensive. They are also prone to mistaking pets and moving objects like branches for people. Similar to microwave sensors, ultrasonic sensors produce ultrasonic waves and measure the reflections from someone moving. Other types of motion sensors used in outdoor lights include vibration sensors and tomographic motion detectors. Some outdoor lights have dual detectors where two different types of sensors are used; e.g. passive infrared and microwave. This reduces the risk of misidentifying pets and objects as people. This one is a no brainer. Go with LED lights. They are better for the environment, they last longer and they use less energy, thus saving you more money. Another advantage of LED bulbs is that they are brighter than similar-wattage incandescent bulbs. Unfortunately, they do not come in high wattages. If you need more brightness, you will have to buy several LED lights. Solar lights will save you money in energy costs. But their downside is that you cannot use them all year round. Since home security does not take a break, you should probably have conventional electric lights installed for use during the colder months. You will still get to save money since you will be using solar lighting most of the year. Ease of installation will depend on the light's power source. Battery and solar-powered outdoor lights are the easiest to install. You simply need to mount them somewhere high. If the light needs hardwiring, you will have to hire a licensed electrician to set it up. This refers to how long the light stays on when it is triggered by the motion sensor. Most lights stay on for 20 or 30 seconds while others have an adjustable illumination period. You can get these lights in either a 2 pack or a 4 pack depending on your security lighting needs. Each pack consists of 20-LED lights that provide as much brightness as 15W incandescent bulbs. The wide-angle design provides large coverage. The motion sensor in the lights can cover a radius of about 8m from the light. The illumination period is 30 seconds though it can be shorter when the battery is not fully charged. Talking of the battery, these lights are solar-powered. This means you can install them yourself - no need to spend more money on an electrician. You also get to save money on your electric bills. On the downside, they will struggle during the cold months. Illumination period will get shorter in autumn and winter. But it's unlikely that they will fail to work at all. That's because the lights use PET laminated solar panels with high efficiency. They maximize solar energy conversion even on cloudy days. What we like about them: High-efficiency solar panels to maximize the amount of solar energy captured. You can use this fixture both as a decorative and security light. It has a beautiful European heritage design with a modern aluminium finish. If you are looking for a decorative garden light, this is a great choice. Functionally, it comes with a long-range motion sensor and works with a 60W bulb to light up a large area. The bulb is not included. You can get the recommended 60W incandescent bulb or use an 8w-12w LED bulb. It will provide just about the same level of brightness but with way less power consumption. An LED bulb is especially beneficial if your motion sensor keeps getting triggered by branches and other moving objects. Installation is easy and straightforward if you are replacing an old outdoor light. The wires will already be in place and all you need to do is connect them to the light. If there are no wires, you may have to hire an electrician. The light is weatherproof. It has an IP44 rating meaning it can withstand a significant amount of dust and splashing water. So a bit of rain wo not do it any harm. The motion sensor has two settings that you can adjust. One lets you set how dark it has to be before the light comes on. The other configures how long the light stays on after being activated by the motion sensor. What we like about it: If you are looking for a minimalist motion sensor light for your balcony, porch or garden, get this beautiful cylinder wall LED from Osram. The fixture has a stylish modern design with a stainless steel finish. It is rated at IP44, making it safe for outdoor installation. The fixture comes with a 6W LED light. It's as bright as a high-wattage incandescent bulb but uses less power. But unlike a traditional bulb that can sometimes be too harsh on your eyes, this Osram light produces a warm even glow. This makes it a great addition to entryways, the garden or the porch. You can install it low on the wall without dazzling everyone's eyes. Installation is easy. Once you've set it up, adjust the light level and illumination time settings. You do this by turning a couple of screws. One lets you set how dark it should be before the light starts coming on. Choose the lowest setting to have it activate only at night. The other screw sets the illumination period after the light is activated by the motion sensor. What we like about it: If you are looking for extra-bright solar-powered motion sensor lights, I recommend this Baxia 2-pack. Each fixture consists of 28 LEDs, providing adequate brightness (around 400 lumens) for your security and illumination needs. The light's 120-degree angle provides wide coverage. The motion sensor in the light can detect movement up to a range of 10 feet (3m). There are no motion sensor settings. The lights will automatically activate at night and stay on for about 30 seconds when they are triggered. There's also no dim mode. It's important that you install the lights where they will receive direct sunlight for several hours a day. This ensures the battery has enough charge at night. This is not a problem during the sunny months. But during autumn and winter, you will notice the lights getting dimmer and the illumination period getting shorter. Installation is easy. No wiring is needed. Just use the two screws provided to secure the light to the wall. You can install the lights anywhere outdoors. They have an IP65 rating meaning they can withstand the elements and quite a bit of dust without any damage. What we like about them: This LED light has a stylish circular design with a black trim. It's a beautiful decorative addition to your porch, balcony or garden. The wide circular design results in warm diffused light rather than a bright spotlight that burns the eyes. But it's still very bright. Rated at 10W, the LED fixture produces up to 700 lumens of light, easily illuminating your entire garden or driveway. The motion sensor has a range of about 8m to 12m. You cannot adjust how sensitive it is (it can at times be triggered by a passing car or pet), but you can set when it comes on and for how long it stays on. Installation is straightforward especially if you are replacing an old light. The wires are colour-coded so it should be easy to hook up the connections the right way. The fixture is IP54 weatherproof, making it safe for outdoor use. What we like about it: If your outdoor motion sensor light is stuck in an on or off position, or does not seem to be working properly, turn off the circuit breaker for at least 30 seconds then turn it on again. Some light may need to be turned off for longer to reset. For motion sensor lights connected to a switch, turn it on for a couple of seconds, turn it off for another two seconds and then switch it on again. You can also try turning the switch on and off five times in rapid succession. Once the light stays on, turn it off and wait five seconds before tuning it on again. If none of these methods work, you may need to replace the bulb. To adjust sensitivity, turn on test mode and set the light to the lowest sensitivity. Walk around the light in circles to see how far the motion sensor's range is. Adjust the sensitivity to tighten range to your liking or make the light more sensitive to movement. To adjust when the light activates, check it has a LUX mode or setting. Turn the dial towards the sun symbol to trigger the motion sensor when it's lighter and towards the moon symbol to have the light activate when it's darker. Also, check if there is a standby time setting. This lets you change how long the light stays on after it's triggered. How to replace a motion sensor for outdoor lights? If the light has a motion sensor built into it, you will need to replace the entire light. But if the motion sensor is external, you just need to remove the light and wall plate to access the electrical connections. Do not forget to turn off the circuit breaker or, just to be safe, the entire electrical supply to your home. Disconnect wires leading to the motion sensor. Remove the motion sensor and replace it with a similar-wattage motion sensor. Reconnect the wires and screw the lights back on.1. Where can I find black lights, solar lights, and stuff like that?home depot cf2. we bought some individual solar lights from English Gardens. They are copper looking ones. My husband?Check that the batteries for insulation. Also look for an on/off switch which some solar lights have. Best to turn them on during the day, then off (or remove the batteries) over night, then on again (or replace the batteries) the next morning to give them a couple of days charge before the first use of the lamps over night.3. Any solar lights give off yellow light?Hi. Yes. Many have a yellow LED. We have a dozen in our yard purchased from Walmart
Motion Sensor Led Prices of Solar Street Light and Poles
therefore, when looking at the prices of the solar street lights, make sure that you put it into context with the availability of warranties. if there are no warranties, perhaps the china baode lights ip66 30w 40w 50w 60w solar street are not as good as they want you to believe.What is the best brand of fishing poles and reels?it depends on how much you fish and what type of reel you are looking for Spinning reel or a Baitcast reel- it's all about what you like best, but honestly baitcast are way better... over all for reels Abu Garcia, Quantum, and Shimano are the best and as for rods, Kistler Rods are one of a kind. They have rods for every kind of fishing. ..Crankbait, jig, worm- you name it they have it!! Good luck, hope you catch a big one!!Are most Poles in chicago liked by non-polish americans?I will be 100% honest with you. My Great Grandparents came from Austria, Italy and Poland... I also have family that came to America in the 1800s from Wales, so my family has been here for going on 4 generations at least. So even though my Grandpa was Polish and I still live in one of the more Polish sections of Chicago, I have to admit I get a little annoyed with immigrants in general not really assimilating into American society? For example, I have a six year old in kindergarten here in Chicago. I had to go to a meeting for the parents and the meeting went on for an hour and a half when it should have been over in 20 minutes. Why? The meeting had to be held in English, Polish & Spanish because so many parents & students have not made such an effort to learn the language here. I remember both my Polish & Italian Grandparents spoke their respective languages in their home, but in public they spoke nothing but English. But in Chicago now, you could certainly move into my neighborhood which is like a tiny Poland and get by only speaking Polish. Anyhow, to answer your question I do not think people here in Chicago are concerned with Poles & our job security any more than we are with Hispanic immigrants & our job security...honestly it does not effect us. I do however get annoyed when I go into Bobaks and the ladies at the deli try to speak to me in Polish before speaking English to me...I can swear in Polish but that's about it. It would be those every day things that bother us.Are you looking for Nordic Ski Walking Poles? Maybe you have seen people out walking with poles?There are millions of Nordic Walkers in Europe - now a business called POLE ATTRACTION makes waves in Australia. Pole Attraction has a Teaching Academy with a variety of courses and is the sole supplier of ONE WAY Nordic Walking poles from Finland. Join the hype and visit www.poleattraction.com.auDoes the Earth's electromagnetic field weaken (significantly) when the north and south poles shift?yes, according to the dominant theory the field weakens considerably when a polarity shift occurs5 Best Trekking Poles to Use on Your Next Hike or Trail RunLike any piece of gear, getting the best trekking pole means exploring your options and finding what works best for your specific adventures Trekking poles (also called hiking poles, walking poles or hiking sticks) can give you the extra balance, stride and speed you need while trail hiking. But with so many different hiking poles to choose from, a search for the right pair can easily become overwhelming. Like most outdoor gear, hiking poles range in price from the inexpensive to heavy budget poles. I spent time talking with outdoor gear experts to see what made for the best trekking poles and factored in features such as shaft durability, grips and locking mechanisms in choosing the best ones. Here are 5 of the bests hiking poles, with descriptions to help you decide which poles may be right for you. At close to $100, these aluminum Black Diamond hiking poles have a high end "one-pull" deployment, making them easy to unfold with one quick movement. They also fold down to 1/3 their full length for easier packing. They have interchangeable carbide and rubber tips so you will have great traction even in icy conditions, and they minimize impact on the ground. These aluminum poles are very popular among ultra trail runners because they are so lightweight and incredibly sturdy. Overall, these poles are recommended for longer trail use and are ideal for trail runners. Note that the rubber tips can be awkward on pavement. They boast what Black Diamond calls SlideLock technology to improve ease-of-use when locking the pole, as well as a three-section foldable shaft. There is a variety of maximum sizing available, with poles that have a max size of anywhere from 39 to 51 inches and a weight of anywhere from 11.4 ounces to 13.4 ounces, depending which of the four sizing options you choose. You can pick up a pair of these aluminum poles for about $60. They are adjustable, collapsible and the hand grips are more comfortable than you would expect. For a beginner, these hiking poles will last you a long time and should work well for hikes under 10 miles in moderate terrain. For steep hikes, you will want to try a more rugged pair. Sometimes with more than 10 to 15 pounds of pressure (as when climbing a steep hill), the locks could give - causing the poles to slightly collapse. Overall, these are a good pair of hiking poles for the price. They will do the job for you in moderate terrain and should last you many years. These poles extend to 55 inches, with a good usable range being between 41 and 55 inches. They use an External Lever locking feature, and have rubber grips. Their weight is just over 1 pound. With a lightweight aluminum tubing and a smaller comfortable foam grip, these hiking poles are smaller and designed more for a woman. They will help take the weight off of your knees and hold up on longer hikes of 20 miles or more. The are very reliable, easy to use and pack away well. Overall, with a price tag ranging from about $50 to $70, depending on the retailer, these poles are a good investment for any avid female hiker. Coming in at 17 ounces, with a max length of 49 inches, these poles usually come with a one-year warranty to give you a little extra peace of mind. These three-section poles are ideal for the experienced through-hiker with a luxury price tag of $200. Considered the "Cadillacs" of ultralight trekking poles, they are adjustable and boast a comfortable foam grip called an AERGON grip, which features a hollow core construction to save weight and create an edgeless, rounded grip for comfortable gripping at all angles especially for "palming" on steeper terrain. These carbon fiber poles weigh in at just 16 ounces. You can easily adjust them with the metal flip lock. Overall, these poles are ideal for extreme hiking for long distance hikers encountering rugged and diverse terrain. The poles use a PE coated, Kevlar reinforced tension cord for long term reliability and have an external locking device. The shaft adjusted for use between 43 inches and 51 inches. You can pick up these aluminum lightweight and adjustable hiking poles on Amazon for just a little over $20, making them the most budget-conscious pair on this list. If you are just looking for some extra support and stability on easy or moderate short hikes, these poles will do the job. But they could bend under moderate pressure if you need to get up a rugged hill. The locks may need to be tightened a few times if you venture out on longer hikes. For the occasional hiker, these budget-friendly poles with cork grips will work just fine. Each pole weighs 10.4 ounces, and they can be adjusted to between 26 (the collapsible length) and 54 inches.

At Wolta Power System, we believe that street light plays a very prominent role to boost up safety and security for drivers, riders and other people at any place.We are well-known solar street light Manufacturer in Uttarakhand, solar street light Manufacturer in Chhattisgarh , solar street light Manufacturer in Bihar, solar street light Manufacturer in Rajasthan and solar street lightQuestion for cops that drive marked police interceptor crown vic?1. There were a number of occasions when I exceeded the posted limit without utilizing my emergency lights. These were calls that needed a timely response, but did not rise to the level of an emergency response. Normally, I could count on being complained on by drivers I passed. I can not recall anyone that pulled in behind me and followed me. 2. I have been passed a number of times while operating at the speed limit by inattentive, speeding drivers. The quicker you went by the more likely you got pulled over. 3. Tailgaters were my personal pet peeve. While I issued a number of tickets for the offense, I can only recall a couple that I issued for tailgating me. I remember thinking the additional charge of "Driving While Stupid" should apply.What interesting thing did you read today?My bladder was full. I saw a Cafe Coffee Day. I went in peed and was walking out.The CCD employee stops me "Sir, this is not a public bathroom".I tell him " I am no public figure either".So he says "Sorry sir, you have to buy something". I tell him "But yesterday I bought two coffees and did not even pee once. So we are not just okay, I am one pee ahead"."What time were you here yesterday, sir?" He counters. "7 PM" I offer. "Sorry sir, I was on duty yesterday too and I did not see you come in"."Not here. Another CCD outlet"."Sorry sir, that does not count. You have to buy something now".Necessity, they say, is the mother of inventions. Sabeer Bhatia wanted to exchange personal email at work and hotmail was born. Mark Zuckerberg wanted to wear blue tee shirts and Facebook was born. Travis Kalanick wanted to harass drivers and hit on his coworkers hence Uber was born.My disruptive idea: An app that tracks your purchases and awards pee credits. Imagine yesterday, I would have bought two coffees and got awarded two pee credits. Today I would have redeemed one pee credit and my pee credit balance would have been one.If only, I would thought of this before, one excruciating conversation would have been avoided. I mean I kinda enjoyed the conversation. It was excruciating for the CCD employee. Especially when I told him " Buddy, you should have caught me on the way into the loo. I would have bought anything. Now I can sit here and argue with you all day. Or you have to wait till my bladder gets full again".P.S. I read it in my facebook timeline!What's the minimum wage in the Philippines? and average costs of clothes?There isnt really a per hour cost per say when they offer you your wage upon salary offer. they tell you what you get in a month. Most call center people and customer care agents earn between P 12,000-16,000/month with a bi weekly pay people who work in department stores cashiers/ attendants may ear between 7,000-10,000/month with a bi weekly pay maids, drivers are on the lowest bracket earning about 3000-4000 a month... monthly pay ----- Shopping Standard brands you can buy clothes in store Like Bench, Penshoppe would cost around 200-500 for shirt or blouse Take note that womens clothing is more expensive than men. In a regular department store in SM a mens polo can cost between 300-600 depending on fabric. T shorts are from 150-300 while local brand name ones are 300-500. Socks are about 100-200 a pair/3pairs Hats may vary from 200-400. But ones you can get in a local streen shop will be below 100 Sunglasses are around 200-300. 400-600 for the Polarized ones of course 1500-2000 for the signature brandsIf all the zoo animals escaped what would you do?We have a rather humble zoo here, not much dangerous. I guess I would hang out on my balcony and watch with bemusement as drivers swerve to avoid the swarm of goats and miniature horses

On top of everything else, a lifetime theft protection plan is also included with this security system. If the camera gets stolen, the Ring company will replace it for free. This is one of the best floodlight camera systems around. On the downside, the motion detection features of this camera could use some improvement. At night, the camera wo not pick up motion closer than 5 feet. This means you may have to take a few steps in the dark before the floodlights are triggered if you are stepping outside from inside of your home. Other than that, This camera is a pretty solid option that allows you to shed light on intruders while simultaneously recording them. The weatherproof outer housing of this camera stands up to water, heat, cold, and shock. You can place this camera virtually anywhere. The voice activation features are handy as well; use this camera with Amazon Echo or Alexa! The camera system expands up to ten cameras with the large Blink surveillance package. This particular package comes with one camera, a cloud storage subscription, a reliable pack of 2 AA batteries, the free application for smart devices, and an instruction manual. The application (iOS - Android) is easy to install and works with all Android and iOS devices. Other impressive features include a sensitive motion detector, HD video, and infrared night vision. The motion detector allows you to capture movement in the designated viewing areas easily when you are not around. Infrared night vision is great for nature footage or protecting your home when it's too dark to see. The HD video capabilities allow you to capture clear and crisp images. This little camera is great for a wide range of tactical or home applications. On the downside, the batteries will need to be replaced after they are done. This camera must be run using AA batteries. It comes with a magnet clip that can be placed using screws or connected to a metal stud with one touch. This is a great camera for anyone who wants an indoor-outdoor option. It also streams via WiFi for real-time video. The WiFi sensors in this camera are pretty strong, you will likely find that your router can be pretty far away and the camera still connects. However, if you have slow internet speeds, this camera may have a bit of a lag. Additionally, it only comes with one free month of Nest Aware. Nest Aware is the cloud storage platform utilized by this system. This means that once your Nest aware free trial is up, you will have to pay to see the pre-recorded footage taken by the camera. If you are not up to purchasing the monthly nest aware services, this camera is not a great option for ongoing monitoring. However, if you do not mind subscribing to the Nest Aware service (from $5 a month with 5 days video history stored), this camera is a fantastic option with numerous helpful user features, sensitive motion activation, and clear video. You will get 3 cameras that are equipped with HD for sharp and detailed video footage. The 100% wire-free cameras help to keep you free of frustrating power cords. They are also weatherproof so you wo not have to worry about rain, wind, snow, cold, heat, or any of the outdoors elements. The rechargeable cameras have long-lasting batteries that charge quickly. A smart siren that projects volumes at over 100 decibels will help to keep your home safe! The loud siren is a great plus, as its motion activated and can be custom set to your specifications. The system also has night vision, a local USB for video backup, and a smart home application that works with IFTTT, SmartThings, and more. There's also a two-way audio speaker s that you can communicate with visitors or family members. If you need a wire-free security system, the Arlo Pro wire-free camera package is a great deal. You can save yourself hassle and money. On the downside, these cameras are a bit more difficult to install than similar options if you choose to mount them. Additionally, they must be recharged which makes them a poor choice for those who vacation regularly. Still, if you need wireless cameras, this is a good deal. The video resolution is around 720p, which is not as high as some similar systems but does the job well enough. The access to video only goes back two hours which can be annoying. Certain subscriptions allow you to get longer video history. Motion detectors and smart alerts keep you updated on everything throughout your day as well. This system works with Android and Apple devices. If you want something that does not look like a camera and functions well, this is a good choice. The only thing that is frustrating is the video history length. You will have to subscribe and pay for cloud services after your first month if you want better video playback. You will get 720 HD picture and night vision as well. The clear images and detailed video that this system offers is another nice surprise. While you wo not get the crystal clear images that more expensive systems offer, you still can see many details at a great resolution. These cameras are more than sufficient enough for most home surveillance applications. The cloud service works pretty well too. The downside with the cloud service is the subscription requirements. You have to subscribe to get access to many of the most desirable features offered by these cameras. They also do not offer any sort of two-way operation. Still, they are weatherproof, durable, easy to install, and great for most remote access applications. For the price, you can not really do much better. Just be sure that the charger is 5V 2A. The full HD 1080p camera also has superior night vision. A starlight image sensor lets you see over 36 ft away in the dead of night. An SD card is built-in for local recording meaning that this camera can operate without the use of cloud storage which can save you money in the long-run. The free application is also free of any subscription costs which is a huge bonus. No base station is needed either. This camera works with routers directly so that you wo not have to worry about complicated WiFi signal boosters. The optional charging methods, however, are our favorite part of this camera. The Reolink solar panel can charge the batteries of this camera so that you will save time, energy, and money. On top of all of that, this camera is also equipped with two-way talking for visitors. All around, this is an impressive remote access camera with tons of unique features for a price you can afford. These weatherproof outdoor cameras are light, durable, and efficient. The system includes a 1TB hard drive for tons of storage. The free application included with this system lets you monitor and view video from anywhere. Smart notifications alert you to activity on your property and allow you to take a look at what is going on when you are not around. This system is possibly the best value that we've seen in a long time. It really has it all! If you need a really superior security system, this is a great option. On the other hand, this system is not quite as user-friendly as many other compact WiFi cameras. It has cords and must be installed properly. It's somewhat more complex than other systems. That being said, it's also very reliable when compared to other WiFi security cameras. In addition to that, you do not need a monthly subscription to use this large dependable system. It also has a mic and speaker so that you can communicate with visitors, night vision, and a wide view lens for a clear and detailed picture of large spaces. If a postal worker rings your doorbell, you will get a notification and be able to immediately communicate information using the two-way speaker system. At night, you will have a clear view of everything going on within the view of this camera. In addition to those things, the processing speed and WiFi connectivity of this camera is really great. You are unlikely to have much in the way of video lag when you use this security system. The 110 wide lens is clear even around the edges and you can easily adjust the picture as you use this camera. This camera is also very secure from theft and is equipped with a loud alarm that can be activated under a number of circumstances. It also can stream to a computer if you wish to have a live feed while you work at your desk. You must subscribe to the YI cloud service to gain access to the footage from this camera which can be frustrating. Other than that, this is a durable and easy to install security camera that works amazingly on a front or back porch. - Wired HD Security Camera For Inside Or Outside All-new Ring Stick Up Cam - Wired HD Security Camera For Inside Or Outside This camera also connects to WiFi efficiently. not a fan of using WiFi for your security camera? No problem. This camera also has a convenient ethernet port for wired use on a desk or bookshelf! The downside of this camera is its need for the cloud service. This camera has no internal memory so if you want to get access to your videos, you will have to pay for a Ring subscription. other than that though, it's a great option that's extremely simple to install and use inside of or outside of your home. Now we will take a look at some of the most frequently asked questions pertaining to motion activated outdoor security cameras. When you are trying to decide which type of security camera system to get, you will likely need to know whether you can use a wired or wireless system. There are definite benefits and disadvantages to both kinds of system and the one you choose will likely depend on your personal preferences and the specifications of your property. Let's compare the differences so that you can see how wired and wireless systems stack up against each other. Wired security systems are both traditional and dependable. You do not have to worry about connecting to WiFi or downloading applications. On the other hand, these systems can be complex, require lots of installation work, and do not always work with your smart devices. Hard to install Do not always stream to WiFi Wireless camera systems are considerably more common these days than their wired counterpart. This is because they are becoming very popular in the private security sector. Families are using wireless cameras more than ever before to monitor their homes, yards, and properties. These outdoor cameras are convenient, easy to use, and quick to install. On the downside, many require applications for use and monthly payments for cloud storage. Easy to install Stream to smart devices No bulky cables or wires Video storage on a remote server Vulnerable to WiFi loss Applications are needed Monthly payments may be needed I want a Hidden camera for outdoor use, what do you recommend? Hidden cameras can be great for a wide range of tactical applications. If you are looking for a hidden security camera, you have quite a few options available. You can either use camouflage accessories to cover or disguise your current camera, or you can purchase a hidden camera specifically designed for outdoor motion activation. If you choose to buy an outdoor hidden camera that has motion activation, you may find that your options are a bit limited. This link will take you to a hidden camera with motion activation that looks like a rock. The Maximus Video Security Camera is also well disguised. It may be easier to simply find a way to disguise a regular motion activated security camera. You can do this by purchasing a light fixture cover and installing it around your camera so that it looks like a porch light. You may also wish to simply install your camera where foliage is thick or in a dark recess on your porch that is difficult to see. Some people make disguises for their cameras using everyday materials as well. When it comes to battery powered and corded cameras, we have to say that corded cameras are usually best for most home monitoring situations. For temporary monitoring, a cordless camera may work well because they are versatile and easy to hide. However, a corded camera is better for continuous or daily use. This can be frustrating if you are away from home or if you lead a busy life. If you want something permanent, you will need a corded camera. That being said, if you are trying to monitor or record only on certain specific occasions, battery-powered cameras work well. They are very easy to disguise and they are also portable. What is "Night Vision" and how well does it work? Night vision devices are denoting devices that enhance nighttime vision. Night vision works by detecting infrared light that can not be seen by the naked eye. Night vision devices collect and enhance all available infrared light to create a picture of what is happening in the dark. Night vision devices work very well outdoors. The visible light in a regular neighborhood is usually more than enough to allow the night vision enhancement features in most security camera systems to work very well. In very dark areas, infrared detection still usually creates a decent picture of what is going on. So, for regular home monitoring, the night vision that most cameras come with will be more than sufficient. How does motion detection work and what range can be monitored? Motion detection technology utilizes PIR sensors that detect motion from various distances away. PIR sensors work differently depending on their equipped working areas. These PIR electronic devices detect changes in infrared radiation in a heat detection area. Now that you are fully informed, it's time to decide which outdoor motion activated camera system is right for you and your family! We hope that one of the cameras on this list fits your individual needs. Did we leave out any impressive outdoor motion activated cameras? Are there any other questions that need to be answered about these devices? Please feel free to let us know! We value your input and want to be able to answer your questions. Thanks for reading and we wish you all the best in home protection.

To any observer on the ground looking at the sky with the naked eye, the sky appears to be a vast spherical bowl, a celestial sphere that extends from all points along the horizon to the zenith, the point directly overhead. Astronomical objects seen in the sky are so far away that observers viewing them without the aid of a telescope have no intuitive sense of which objects are closer than others. This lack of depth perception causes everything to appear equidistant on the sky. Any object's position on this sphere can be determined by two coordinates, which designate the object's horizontal and vertical location. The vertical coordinate is determined by measuring an altitude angle upwards from the nearest point on the horizon, and the horizontal coordinate is established by measuring an azimuth angle from due north eastwards along the horizon to that nearest point. This system is called either the horizon coordinate system or the altazimuth system (see Figure 1). About 6,000 stars are visible to the naked eye when you can achieve the darkest conditions. The positions of the stars relative to each other remain fixed from night to night and year to year. In general, stars in the same area of the sky have no physical relationship to each other, but the very human tendency to impose order upon otherwise random distributions yields patterns of brighter stars, or constellations. Many constellations of the Northern Hemisphere have been inherited from antiquity, including Ursa Major, the Big Bear, of which the more familiar Big Dipper is part, and Orion, the hunter, which can be seen in the winter sky. Many Southern Hemisphere constellations were defined in the last century to fill in unlabeled regions of the sky. The sky is now officially divided into 88 constellations, which are used in modern astronomy for naming purposes. For example, the star alpha Ursa Majoris ( UMa) is located in the Big Bear constellation. Therefore, Ursa Majoris comes from the name of the constellation, Ursa Major, and the Greek letter indicates that it's the brightest star within that constellation. In addition to modern names, some 90 or so stars also have names from antiquity. For instance, UMa is also known as Dubhe. Over the course of the night, stars move across the sky from east to west as a consequence of Earth's rotation on its axis. The stars appear to move in circular paths around a celestial pole, or either of two points on the celestial sphere where the extensions of Earth's axis would intersect. In the Northern Hemisphere, the celestial pole is coincidentally marked by the relatively bright star alpha Ursa Minoris, also known as Polaris. Simple geometry shows that the altitude angle of the pole star above the northern horizon is equivalent to the latitude of the observer on Earth. To an observer in the Northern Hemisphere, stars that are always above the northern horizon are known as circumpolar stars; an observer in the Southern Hemisphere would see circumpolar stars around the south celestial pole. Stars that are further to the south and that rise and set sometime during the night are called equatorial stars. Equatorial stars rise in the east, move diagonally into the southern sky, achieving their highest position above the horizon on the meridian (the great circle that extends from due north on the horizon, through the zenith, to due south on the horizon). From the meridian, these stars move westward until they set below the western horizon. The celestial equator is that great circle formed on the celestial sphere by extending the plane of the Earth's equator. The equator intersects the horizon due west and due east. An immediate consequence of Earth's rotation is identifying the preferred directions of north, south, east, and west around the horizon, called cardinal directions, by which humans naturally orient themselves. Minute by minute, over the course of the night, both the altitude and azimuth of a star continually change. To more easily observe and track celestial objects, scientists have defined celestial coordinate systems that are fixed upon the sky and thus move with the stars. The equatorial coordinate system is a projection onto the sky of Earth's latitude and longitude coordinate system. Celestial latitude, known as declination, is the angular position north or south of celestial equation. Celestial longitude, measured around the celestial equation, is known as the right ascension (see Figure 2). Declination is measured in degrees, minutes of arc, and seconds of arc. Recognizing that the stars appear to move once around the sky in one day (24 hours), right ascension is measured not in degrees, but in hours, with 24 hours of right ascension (to distinguish from 24 hours of time) equal to 360 degrees. Like the stars, the Sun rises and sets every day. However, unlike the fixed motion of the stars, the Sun's daily path across the sky varies throughout the year. Twice annually, at the vernal equinox (about March 21) and the autumnal equinox (about September 21), the Sun's position coincides with the celestial equator; it rises due east, moves across the sky following the path of the equator, and sets due west (see Figure 3). At this time of year, the length of the day is the same as the length of the night. During the summer, however, the solar position is north of the equator, achieving a maximum northernmost declination of 23.5 degrees at the time of the summer solstice, around June 21. In the winter, the solar position is reversed, with the Sun at its maximum southernmost declination of -23.5 degrees at the time of winter solstice, December 21. The terms equinox and solstice mark not only specific times of the year, but also specific points in the sky. The vernal equinox is that position on the celestial equator where the Sun crosses from the southern into the northern sky. Celestial longitude (right ascension) is measured eastward around the equator from this point. The Sun's seasonal positions in the sky. Relative to the background stars, the Sun also moves about one degree eastward each day, thus encircling the sky in the course of a year. This ecliptic, or the great circle on the celestial sphere defined by the solar path, is tilted with respect to the celestial equator by 23.5 degrees. Throughout the year, the ecliptic passes through the 12 zodiacal constellations. Because the apparent solar movement is caused by Earth's motion around the Sun, the ecliptic plane is also a projection of Earth's orbit about the Sun. That Earth's rotational equatorial plane does not perfectly match its orbital plane (the ecliptic plane) about the Sun is directly responsible for the annual northsouth movement of the Sun and the consequent seasons. The length of the year is based on the time that the Sun takes to complete its annual path around the sky. During the year, the stars and constellations visible at night change as the seasons pass through their cycle. A year is, in fact, 365.25 days long. To keep the calendar in sync with the actual seasonal passage of time, every four years we have a leap year, or a year of 366 days. The additional day, February 29, makes up for the time lost annually when the 365.25 day cycle is computed as 365 days. The length of a day is based on the time it takes for the Sun to complete its daily path across the sky, from its crossing of the meridian at noon to its next crossing of the meridian the next day. Daily time based on the hourly position of the Sun in the sky, relative to its noontime position each day, is called apparent solar time. To astronomers studying the stars, however, the time of day alone is not a sufficient method for determining which stars can be observed at any given time. Astronomers need to know both the time of day and where the Sun is in the sky to find out which stars they can observe. More specifically, what is of interest to an astronomer is the sidereal time, or the right ascension of the stars that are crossing the meridian at any moment. Sidereal time and solar time are not equal because of the annual motion of the Sun across the sky. The true rotation period of Earth is 23 hours, 56 minutes, but the length of the day is four minutes longer. In one rotation of Earth, the Sun has moved roughly one degree across the sky, thus Earth has to rotate a little bit longer to get the Sun back to the same position on the sky. The solar day is 24 hours long. The actual length of any given day varies throughout the course of the year for two reasons. First, Earth's orbit around the Sun is not a circle, but an ellipse. The Sun's apparent motion across the sky therefore varies slightly, moving more than the average one degree per day in January, but a bit less than the average in July. Second, the solar motion along the ecliptic moves parallel to the celestial equator at the times of the solstices when the Sun is farthest north or south of the equator, but at the times of equinoxes, its motion is at an angle to the celestial equator. What is important for the length of the day is only that part of the solar motion parallel to the equator. This produces a second variation to the length of the day. The difference between apparent solar time (which would be shown by a sundial) and mean solar time (which would be shown by a clock or watch) is called the equation of time. This is a complicated effect involving orbital mechanics (the motion around an ellipse is not uniform), perspective (a moving object closer to the observer has a greater apparent motion), the tilt of the ecliptic to the equator (hence the daily component of solar motion across the sky varies from equinox to solstice), and a geometrical factor resulting from the fact that we are dealing with a spherical coordinate system; this latter you can demonstrate to yourself by placing your thumb on the equator of a globe. Note how much longitude angle it covers. Now place your thumb near the north pole. Your thumb will cover the same area, but as measured in longitude, it covers a much bigger longitudinal angle. And it's that angle that is important for rotation and hence the length of a day. Noon, as defined by mean solar time, can occur as much as 16 minutes late in October or 14 minutes early in February compared to the Sun's actual crossing of the meridian. Observation of the Moon shows that it not only appears to change its position by moving around Earth, but at the same time, the fraction of its surface that is illuminated by sunlight (its phase) also changes (see Figure 4). When the Moon is directly opposite the position of the Sun, it appears totally illuminated, or in full phase. When the Moon is viewed at an angle of 90 degrees from the position of the Sun, its surface appears half illuminated, or in its quarter phase. Between full and quarter Moon, the phase is said to be gibbous. If less than half the Moon is illuminated by sunlight, the phase is crescent. When the Moon is in the direction of the Sun and the side toward Earth is its dark or shadowed half, the Moon is said to be new. The cycle from new Moon waxing (increasing illumination) to first quarter to full Moon, then waning (decreasing illumination) to third quarter and back to new Moon takes 29.5 days, a period adopted as the basis of our calendrical month. The lunar phases are observed because of the changing geometrical orientation between the Sun, Moon, and Earth over the course of the lunar month, not the result of Earth casting its shadow on the Moon. The Moon takes 27.3 days to move once (360 degrees) around Earth as determined by its orbital position relative to the stars; the orbital period is therefore also an example of a sidereal period, a period measured relative to the stars. This 27.3 days can also be called a sidereal month. The time from full Moon to full Moon is longer, 29.5 days, because two motions are involved: the motion of the Moon around Earth and the motion of Earth around the Sun. To become full again, the Moon must move more than 360 degrees around Earth. The lunar month, or lunation, is thus an example of a synodic period, or a period produced as the consequence of two motions. The term synodic month is also applied to this 29.5 day period. Another example of the difference between a sidereal period and a synodic period is the rotation of Earth (23 hours, 56 minutes) and the length of a day (24 hours). The actual path across the sky of the Moon is quite complicated. The lunar orbital plane is tilted about 5 degrees 9 minutes with respect to ecliptic plane. The orientation of these two planes rotate with respect to each other over an 18.6 year period. In consequence, relative to the celestial equator, the lunar orbital plane has a variable tilt that periodically oscillates from 23.5 degrees minus 5 degrees 9 minutes equals 18.3 degrees, to 23.5 degrees plus 5 degrees 9 minutes equals 28.7 degrees. In other words, over the course of the month, the Moon can oscillate north and south across the celestial equator between declinations of as little as 18.3 degrees to as much as 28.7 degrees. Each month the path of the Moon across the sky differs slightly from its path the prior month and from its path the next month. In contrast, each year the solar path around the sky is essentially the same. Astronomers find particularly interesting the two intersection points, or nodes, between the great circles of the ecliptic plane and the lunar orbit. If the Sun and Moon in their motions about Earth move simultaneously through nodal positions, an eclipse occurs (see Figure ). If the Moon and Sun are at the same node, the Moon passes in front of the Sun and a solar eclipse results, lasting only a few minutes in duration. If the two are at opposite nodes, then the Moon passes through the shadow of the Earth and a longer duration lunar eclipse occurs. The cycle of occurrence of eclipses is quite complicated because three factors are involved. The Sun moves around the sky in 365.25 days. The Moon moves once around the sky every 27.3 days. The direction to a node (where the two orbital planes intersect) moves around the sky in 18.6 years. To get an eclipse, all three positions (Moon, Sun, and node) have to be along a straight line through Earth. This event does not happen with a simple pattern of regular time intervals. Nakedeye observers in antiquity recognized five other objects that move across the sky relative to the stars - the planets. The word planet comes from the Greek, meaning "wanderer." Planetary motion is more complicated than that of the Moon or Sun, which move systematically west to east relative to the stars. The planets' usual motion is west to east, termed direct or prograde motion. But in each synodic period, planets show a brief period of motion in the opposite or retrograde direction. Retrograde motion is the result of perspective. Consider, for example, driving on a freeway. You look forward toward a slower moving car. Relative to the distant mountains, it is clear that this car is moving in the same direction you are moving. But as you catch up to and bypass the slower car, you see it appear to be moving backwards compared to the distant horizon. As you pull ahead, once again looking back at the slower car shows it to be moving forward. Observation of other planets from Earth produces the same apparent reversal of motion relative to the background of stars. (See Figure 6).

Some are just limit switches, others give a readout of the tilt angle. The function is the same as a spirit level (carpenter's level) or a plumb bob. One idea would be a portable weighing scale. Usually these have levelling screws and a small spirit level. It could be made to automatically correct for errors when not level, by using tilt sensors, though you would need 2 sensors, one for x and one for y. A tilt sensor measures the angle according to the earth's gravity, so the horizon. It can be used to determine how close to vertical or horizontal something is. Maybe it could be an electronic carpenter's level.what should i buy for my nephew first birthday?The ideas are vast, the items endless!
