What is the reason why the aftermarket reversing camera sometimes displays and sometimes does not?

Check the wiring connection between the reversing radar and the vehicle's installation to see if there is a loose connection—poor contact can cause the reversing radar to intermittently function. Here is some relevant information: 1. Working principle: The reversing camera uses a wide-angle infrared camera installed at the rear of the vehicle, which clearly displays obstacles behind the car on the in-car display screen. 2. Function: When the reverse gear is engaged, the system automatically activates the high-definition reversing camera at the rear of the vehicle, displaying the rear view clearly on the reversing LCD screen, allowing the driver to accurately assess the road conditions behind. This system provides a more intuitive and clear view of the rear when reversing, making it one of the most practical configurations for reversing safety.
I've been driving for over a decade, and the aftermarket reversing camera acting up from time to time is really a headache. The most common causes are loose wiring connectors, especially when bumps on the road shake the connection points, leading to intermittent signals; there's also poor power line contact, such as unstable battery voltage or oxidized connectors; additionally, the camera itself might have issues, like dust or water getting into the lens causing short circuits, making it work intermittently. I remember once my camera failed several times after washing the car, and it turned out the trunk connector wasn't sealed properly. I suggest starting with the easy fixes first: check if the trunk wiring is securely fastened, then clean the connectors with a damp cloth. If that doesn't work, take it to a professional repair shop for a thorough check—don't risk safety to save money, as a sudden black screen while reversing can be quite dangerous and easily lead to accidents. During regular maintenance, pay extra attention to the installation areas to prevent dust or moisture intrusion.
I've installed backup cameras several times myself and have also encountered issues where they sometimes work and sometimes don't. Possible reasons include loose wiring during installation causing connections to come undone due to vehicle vibration; unstable power supply, such as poor contact in the wiring from the taillight causing voltage fluctuations; or poor camera quality, where using inferior products leads to intermittent failures. I once spent an entire day troubleshooting only to find out the connector wasn't plugged in firmly—pressing it in by hand fixed the issue. I recommend manually checking all connection points to ensure they're secure and not loose; test the voltage stability, you can buy a simple tool to do this yourself; if the original car system isn't very compatible, consider upgrading the software or switching to branded accessories. However, avoid repeatedly disassembling and DIYing, as it can easily damage more components—safety first. If problems persist, take it back to the original installation shop for rework.
