How to Solve the Flickering Issue of Rearview Camera?
2 Answers
The most convenient solution for a flickering rearview camera is to have it inspected and repaired at a maintenance shop or directly replaced. Below are specific solutions for addressing the flickering issue of a rearview camera. 1. Unstable voltage. It is recommended to purchase a voltage regulator and install it on the power supply line of the camera. 2. Video signal interference. It is advised to use coaxial shielded video cables to resolve interference issues. 3. Poor camera quality. It is recommended to purchase a camera from a well-known brand. 4. Incompatibility between the display host and the camera's video signal. It is suggested to find a video signal that matches the host or purchase a video signal converter.
I had a car with a common issue of reversing camera flickering, and I encountered it last month. Initially, I thought it was a camera problem, but upon closer consideration, the causes could be varied. Start with the simplest step: wipe the camera lens with a clean cloth—dust or dirt often leads to unstable images or even flickering, something many overlook. If it still flickers after cleaning, check the wiring connections, especially around the trunk area, to see if any plugs or power cables are loose. Sometimes, simply reconnecting them a few times solves the problem. If that doesn’t work, the camera itself might be faulty or there could be insufficient power supply, requiring replacement or adding a voltage regulator. In my case, I later discovered some corrosion on the battery terminals, and cleaning them fixed the issue. Regular maintenance while driving is key—don’t wait for problems to arise before acting, as reversing safety is crucial. If you encounter flickering, stay calm and troubleshoot step by step for a safe and efficient solution.
