There is no image in the spare camera when it is hot.

Maybe the camera is broken or blocked.

If the camera is damaged and the image cannot be uploaded to the computer, it cannot be displayed naturally. In this case, you have to go to a repair shop or a repair shop for repair, and you can replace the camera if necessary. If there is only a foreign object blocking the camera, take it away.

First check whether the camera of the reversing radar is normal. If it is damaged, it needs to be replaced. Secondly, check whether the image power supply of the reversing radar, that is, the place where the reversing lamp is connected, is loose. If there are signs of looseness, it needs to be reinforced.

The method is to check whether the reversing lights are normal. If the light is broken, your reversing radar image function may not be triggered. The solution is to take the lights apart and then connect them.
