How does IR work?
The human eye can see in the visible light portion of the spectrum chart (below). Above visible light is infrared (IR). The CCD or CMOS device inside your security camera can detect IR light and use it to help illuminate the area viewed.
Below are cameras that emit IR so that the area in front of the camera can be seen in total darkness. ONLY black and white (B/W) cameras are affected by IR illumination. Color cameras will detect IR to a much lesser degree. Take your TV remote and press a button while pointing it at your camera for a simple demonstration of how a CCTV camera can see IR.
You need video surveillance. But you need it at night, in low light areas, and you're afraid of investing in a product that will not give you the returns you desire. The answer to this problem is an infrared camera. An infrared camera is an ideal product for anyone needs to capture images in the dark for work or pleasure.
An infrared camera uses infrared light instead of the regular lighting spectrum in order to produce better images in complete darkness or low light conditions. Night vision cameras are usually black and white, but with the expanding technology IR capable Day / Night Cameras are no available.
Infrared options
A regular camera can become an infrared camera with the use of infrared illuminators. The illuminator lights the area under surveillance with infrared light so that that your regular camera can record black and white images with the use of infrared radiation, which the naked eye cannot see.
Do not confuse an infrared camera with a day/night camera. Day/night cameras can record in low light, but not in zero light and do not use infrared lighting.
Infrared cameras are also available in a CCTV camera system. You may already be considering a closed circuit television security system because of its superior security options, as it constantly monitors and records activity. Consider a CCTV infrared camera in order to get a high level of night time security, the time when it matters most.
The complexity of your infrared camera system is entirely up to you. An infrared camera can grow with your needs, becoming more elaborate as the situation demands. The cameras are often lightweight and easy in both use and set up.
See it to believe it!
In order to fully understand the clear images that can be produced in complete darkness, you have to see it. Most manufacturers have examples the kind of recordings you can view on their websites. Take a few minutes today to browse through these websites to get a fuller grasp on imaging from infrared cameras.
