Dahua Smart Dual Light uses smart algorithms for accurate target recognition. In nighttime conditions, the IR lighting is active as standard. When a person or vehicle is detected, the camera automatically switches to warm light for a full-color image. Once the target leaves the monitored area, the camera switches back to IR illumination, minimizing light pollution.
