Infrared cameras are cameras, guards, infrared lamp, power cooling modules and combine them into one of the cameras. It implements the basic principle is to use night vision common CCD monochrome cameras can see infrared light spectrum (that can be visible or infrared), with infrared light, as "light source" for night vision Imaging. The power and angle of the IR led, infrared camera configuration, certain focal length of infrared lenses, and whether there is good power supply thermal management are important parameters to judge the performance of infrared cameras.
