Definition:A kind of device that generates the infrared ray(IR) which could help the CCTV camera “see” the subject without light source. Its wavelength we mostly use is 750nm (sometimes cause the problem of the visible infrared ray )and 850nm.

Operating principle：

The CCD will lose its function without the light source, like in the absolutely dark environment. As the CCD has a great induction to the infrared ray, so we commonly use the IR led as the light source to support the CCD works well.

when the IR Led works, its infrared ray will reach to the subject and will be reflected to the camera, so the reflected light will be inducted by the CCD.
