What is the reason why the infrared light of the surveillance camera doesn't light up at night?

1. There is something wrong with the power supply of the device. When the infrared light is turned on, the power of the monitoring camera is larger than that when it is not turned on, which is generally 2 ~ 3 times that when it is not turned on. If the power supply quality is not good, or the wire diameter is not enough, and the total power supply UPS power is not enough, the infrared light will not be turned on.

2. Is the camera still working properly? If you work at night, and it is black and white, it is the problem of infrared light. If the color image is normal during the day, it will not work normally at night, which is the reason of insufficient power supply. If there are color images all day long, it is artificially set, and there is no problem anywhere.

3. There is something wrong with the photoresistor on the infrared lamp board, and the infrared lamp board is burned. The power supply of the infrared lamp panel is not working properly. The infrared lamp sensor is damaged, and the infrared lamp power supply is missing or insufficient.

The reason why the infrared ray of the surveillance camera doesn't light up at night is that the power of the infrared lamp is not connected. There should be two red wires to cut off the power connector, both of which are connected to the positive pole. Monitoring system is one of the most widely used systems in security system, which consists of front-end part and control part.
