The Jinbei photography light is not on, and the flash is normal.

1. There is something wrong with the power supply of the device. The power of the surveillance camera when the infrared light is turned on is larger than that when it is turned off, which is 2 to 3 times that when it is turned off. If the wire diameter is not enough, the total power of the power supply UPS is not enough, and the power supply capacity is not enough, the infrared light will not be turned on.

2. The environment where the camera is located is too bright, surrounded by light sources and incandescent lamps. The camera can't enter night mode, and the infrared lamp can't be turned on.

The infrared detector and camera are broken. Cover the infrared detector on the camera, and the infrared light will light up if it is normal.
