What Causes No Signal in Car Rearview Camera?

[VonPhoebe]

There are two main reasons for no signal in a car rearview camera: 1. The data cable connected to the rearview camera is loose or has poor contact. 2. The rearview camera is damaged. First, check if the reverse lights are functioning properly when reversing. If they are, inspect whether there is a reverse light signal on the signal line behind the rearview video. If there is, it indicates an issue with the main unit or the camera. If there isn't, it means the reverse light signal line is not properly connected or is loose. Here is some extended information about rearview cameras: The car rearview camera system uses a wide-angle far-infrared camera device installed at the rear of the vehicle, allowing clear visibility of obstacles behind the car through the display screen inside. Even at night, objects can be seen clearly via infrared. Professional vehicle-mounted probes have further enhanced anti-magnetic, anti-shock, waterproof, and dustproof performance.
