What is the reason for the reversing camera not switching on the dash cam?

[June]

The phenomenon where the reversing camera does not display when the reverse gear is engaged is most likely due to poor line contact. It is necessary to promptly check the wiring and the connection points where the lines are installed in the vehicle to see if there is any loose connection. If the line contact is poor, it can cause the reversing camera to work intermittently or even result in a black screen. In such cases, simply ensuring the loose connections are properly reconnected should resolve the issue. If the reversing camera still does not display after checking the above conditions, it may be due to the prolonged use of the reversing camera, leading to poor chip photosensitivity. This not only causes a snowy screen effect but can also result in a complete black screen in severe cases. In such situations, it is necessary to visit a repair shop for inspection and repair or to directly replace the camera.
