VIDEO SURVEILLANCE CAMERA WITH SOLAR DETECTOR

摘要

A video surveillance camera has an infrared (IR) light emitting diode (LED) for emitting IR light, and a solar detector for detecting visible light. And the video surveillance camera can control the infrared light emitting diode to emit the IR light according to a level of visible light detected by the solar detector. Therefore, the video surveillance camera can fully turn the IR LED off or on when the level of visible light changes, even in the presence of invisible light.
