Mostly crime occurs in the night, and that makes it a necessity that your security camera should have the ability to see in the night. Night vision security cameras are one such kind of cameras, which can see the things even in complete darkness. They are used for purposes like monitoring entrances of the building, identifying criminal activities, keeping track of intruders, and medical imaging.
There are many types of cameras available in the market. To decide which camera will suit your needs and which one you should buy, some home work is required. The different types of night vision cameras are:
Outdoor wired night vision surveillance camera: these are ideal for outdoor applications. Using this camera, you can monitor whatever is happening in the area covered by the camera. Motion Sensor Cameras: They use sensors to detect motion. Recording is only started, when the sensor sees some motion. The advantage of this kind of camera is that it reduces the recording time. Vandal proof night cameras: These cameras are used in vandalism prone areas. These cameras are very sturdy and difficult to be ruined by a vandal. Day night color cameras: color recording is done during day time. And in night, the camera automatically switches to black and white mode. Infrared night cameras: Night vision cameras work well even in low-light conditions. But for places with no light, infrared night vision camera is required. Mobile spy night cameras: As the name suggests, mobile spy cameras are mobile and can be placed anywhere near the area you want to do recording. Night vision is used when you use these cameras in night as they can see things even in dark. Wireless night vision camera: are very easy to use. These cameras can be moved anywhere without re-installation.
Night vision cameras with infrared feature can be used in any kind of lighting conditions, low light condition, or no light condition. The advantage of a night vision camera is that it can see things, which is otherwise not visible to a ***** human eye. However, night vision cameras with infrared illumination are quite expensive comparative to its other counter parts.
Choosing a security camera that fulfills all your requirements is not an easy task. There are so many security cameras available in the market that it may confuse you in deciding, which camera you should buy. The basic factors that you should consider before buying are: type of application (indoor or outdoor), camera resolution (low or high), camera model (static or PTZ model), and the type of camera (day/night or only night vision).
You should always consider laws before using a night vision security camera [http://www.sunsecurity.com/security-cameras-night-vision-cameras-c-119_151.html] It is also very important to know that it should not violate other person’s privacy. Wireless night vision cameras and spy cameras are useful to record something without the knowledge of the other person. But this should be done considering the other person’s right.

Video cameras are the watchdogs of the world. Where criminals would usually have free access, video cameras, both hidden and visible throw floods of fear on would-be intruders. It’s one thing in court for them to lie about where they were that night. It’s quite something else trying to lie about a video of them doing what they are charged with.
Video surveillance is relatively new and the technology is changing rapidly. If you’ve bought an electronic wrist watch in the last year, you have more computing power on your wrist than the command modules of the astronauts that circled and landed on the moon.
Not long ago, you had no choice, but to have the cameras wired together or all wired to a central console. This was very expensive and had to be installed by professionals. Now, you can buy wireless cameras that can be mounted anywhere by anyone that can handle a screwdriver. Some of these units have their own pedestal. They don’t even have to be screwed in!
The wireless technology is so advanced that the cameras have a range of 500 feet. If you want to spend the money, you can buy video cameras with a range of up to double that.
Like the human eye, video surveillance cameras are affected by the intensity of light, by moisture and chemicals in the air. Special hazardous environment cameras can be bought for industrial purposes, but for the home, you don’t have to worry about these cumbersome units.
Your home cameras will have to deal with darkness and moisture, however. Any good surveillance camera kit with have at least one night vision camera. This is another example of technology racing forward. Not long ago, only the military could afford these. Now, they are readily available and better than anything they used in Viet Nam.
Outdoor video cameras come in waterproof cases. They also usually come with the night vision feature although you should always check the manufacturer’s literature to double check.
Some security cameras are made to be boldly displayed so that anyone going into its field of view will know they are being watched. Other cameras are disguised as household articles. Some people use them for intruder watching. Others use them to keep an eye on employees like the famous Nanny Cameras.
Security cameras are wonders of technology. With a little research and a very modest investment, you will add immensely to your peace of mind and the security of your home and business.
