The main faults include jittery screen, no image, and blurry screen.
1. Screen shake: The screen shake of the vehicle camera is generally due to the looseness of the bracket that fixes the subject of the lens, which causes the vehicle camera to tilt the picture.
Suggested method: adjust the angle of the bracket, and fasten it well to prevent it from loosening again.
2. No image: The vehicle camera has no head image, usually because the plug is not plugged in (loose) or the system connection line is disconnected. It is recommended to check whether the plug is inserted well and whether the system connection is disconnected.
3. The picture is blurred: the picture of the vehicle camera is blurry, which is probably caused by the accumulation of a lot of dust and uncleanness in the lens part. It is recommended to clean the lens.
1. Frequently asked questions
Due to different geographical habits, some models have a large output voltage interference after the engine is started. The power supply to the reversing light is not a pure DC power supply, but a pulse signal is superimposed on it. If conditions permit, you can test it with an oscilloscope. A signal that resembles a square wave.
If the vehicle camera does not have a filter (some people call it a rectifier), and the power supply line of the vehicle camera is directly on the reversing light, the vehicle camera will not work properly because of the extremely unstable working voltage, and the output video signal will also be abnormal. What you see on the host is serious interference, jitter, or the reversing screen does not switch.
