Do I have to turn off the red light of the circular camera if it doesn't work?

The red light of the circular camera may not be turned off. The monitoring camera is equipped with infrared function, and the infrared light is automatic and controlled by photoresistors. When the light is sufficient, the infrared light is automatically turned off, and when the light is insufficient, the infrared light is automatically turned on.

The working principle of the infrared camera is that the infrared light emitted by the infrared lamp irradiates the object, and the infrared light is diffused and received by the monitoring camera to form a video image. The current high-definition camera is still relatively high-definition and sensitive, so you should pay attention to it under the camera.

Extended data:

Infrared camera is sensitive to temperature, which can form images according to the temperature and quantitatively identify the temperature data. Users can define the temperature alarm limit. Not only infrared forest temperature image display, but also temperature data display and abnormal temperature alarm signal output.

The monitoring area is large. When the infrared thermal image monitoring head works, it passively detects the infrared thermal radiation of all targets in the picture. It has 76,800 detector units and measures the temperature data of 76,800 pixels in the whole picture at the same time.

This is a thermal image with temperature distribution. The detection angle is horizontal 24 and vertical 65438+08. The effective detection area is related to the distance. Infrared thermal image monitoring head belongs to area array detection equipment, and the monitoring area is extremely large.
