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