What is a dual light source surveillance camera

文章出處:責任編輯:人氣:-發表時間:2020-12-09 15:44【

Dual light source monitoring camera means that the camera can support two kinds of light signal control, and there are two kinds of lights (such as infrared light and white light) on the light board with photosensitive light.

The dual light source function of the monitoring camera is mainly reflected in the alarm at night. Under normal conditions, the camera turns on the infrared light at night and the image is black and white. When the human figure detection or movement detection alarm occurs, the camera will turn on the white light and the image will be switched to color, which can frighten the bad people and warn the users.
