Abstract
A detection system includes a visible light detector, an infrared detector, and a processing circuit. The visible light detector is configured to detect visible light. The infrared detector is configured to detect infrared light. The processing circuit is configured to determine whether a parameter of the visible light detector is larger than a threshold. If the parameter of the visible light detector is larger than the threshold, the processing circuit executes a human presence detection according to the infrared light detected by the infrared detector, and generates a human presence detection result.
