If the astern camera is foggy and white, you can remove the astern camera and dry it with a clean rag, or dry it with a hair dryer, which should be careful not to get too hot. After dealing with the fog from the camera, apply some glass glue at the entrance to strengthen the seal and prevent water from entering.
Reversing images usually appear in two situations, one is direct no reaction and no display, the other is foggy or gray, people can not see clearly. When this happens, we need to analyze the cause first.
If it is in the daytime in summer, when the sunlight is dazzling, the reversing image will appear hazy, which is caused by the strong white light. In this case, we only need to buy a plastic mask and stick it on the top of the lens, so as to avoid the exposure of strong light, which will affect the use of the reversing image. If it’s rainy or snowy or dusty or humid, we just need to wipe the camera with a tissue. You can also spray some anti-fogging agent on the camera to prevent such problems.
If the reversing image is not gray, but snowflakes, current or red and blue lines, it is usually caused by poor line contact or camera failure. At this time, it is necessary to check whether the circuit is normal and there is no bad contact. If everything is normal and the camera is still like this, it is the reversing image itself. It needs to be repaired or replaced.
