Smart dual-light monitoring means that the camera has two control modes of supplementary light (white light and infrared) at the same time, and it can be set to work in one or two supplementary light modes. The role of the smart dual-light mode in the surveillance camera is reflected in the aspect of alarm or convenience. Under normal circumstances, the camera turns on the infrared light at night and the image is black and white. When a humanoid detection or motion detection alarm occurs, the camera will switch to white light mode to illuminate the monitoring environment, and the image will switch to color, which will illuminate passersby, but for criminals, it is a deterrent and warning.
