1. There is a problem with the power supply of the equipment. The power of the monitoring camera when the infrared light is turned on is larger than that when it is not turned on, which is generally 2 to 3 times the power when it is not turned on. If the wire diameter is not enough, the power of the total power supply UPS is not enough, and the power supply capacity is not enough, the infrared light will not be turned on.
2. The brightness of the environment where the camera is located is too high, and there are light sources or incandescent lamps around it, so the camera can't enter the night mode, and it can't turn on the infrared light.
3. The infrared detector or camera is simply broken. Cover the infrared detector on the camera with your hand, and if it is normal, the infrared light will light up.
Camera, also known as computer camera, computer eye and electronic eye, is a kind of video input equipment, which is widely used in video conferencing, telemedicine and real-time monitoring.
