People's eyes can see the visible light according to the wavelength from long to short followed by red, orange, yellow, green, blue, blue, purple. Longer than the purple wavelength of light called ultraviolet light; longer than the red wavelength of light called infrared, the human eye can not see the infrared. Because the digital camera with the CCD sensor all the light which caused the shooting image and we only see the visible light produced by the image is very different. In order to solve this problem, the digital camera in the lens and CCD installed between an infrared filter, its role is to allow a certain band of infrared light through, absorb or reflect visible light and ultraviolet light. At present, most infrared cameras use LED infrared light-emitting diodes as the main material of infrared cameras.
