Surveillance ? IR illumination
 
If you are installing video surveillance systems often a problem obtain good image viewing area in low light conditions at the facility. This fully can be attributed both to the closed premises to shut off or emergency lighting, and to objects in the open air. This problem can be solved in different ways: the installation of expensive high-sensitivity cameras, the organization of artificial lighting or installing systems, infrared illumination.
Virtually all modern cameras are based on light-sensitive CCD. Most of the "cheap" cameras have a sensitivity no more 0.1 lux, which gives an acceptable quality of the image of the object on the monitor in the clear night with full moon. Often optimal use of customary artificial light visible range. It is preferable least because it allows camcorder operates at maximum its sensitivity. But, for obvious reasons, this is unacceptable in the conduct of covert surveillance at the facility. In such cases the most appropriate is the installation of infrared illumination.
In comparison with the human eye sensitivity black and white cells significantly shifted the infrared region, which allows use in poor lighting conditions, special infrared illuminator. Infrared radiation is not visible to the human eye, but very well recorded video camera.
At the organization of infrared illumination is necessary to take into account that the device lights themselves are divided into two basic types: with visible and invisible infrared emitters.
