Why is the rear camera of the dash cam not displaying?

[LeNova]

The reasons why the rear camera of the dash cam is not displaying: 1. Loose plug. Since the dash cam plug is always inserted in the interface, when the vehicle is moving, the vibration and shaking of the car body can easily cause the plug to loosen; 2. Wiring issues. In this case, you can remove the wiring and check if there is any damage or aging in the rear camera wiring; 3. Problems with the camera or dash cam. A dash cam is an instrument that records images, sounds, and other related information during vehicle travel. After installing a dash cam, it can record the entire process of the car's movement in video and sound, providing evidence for traffic accidents.
