Why is the reversing camera shaking?

The phenomenon of horizontal stripes shaking in the reversing camera is most likely due to poor contact in the wiring. Below is relevant information about the reversing camera: 1. Introduction to the reversing camera: The reversing camera, also known as the parking assist system, or backup visual system, or vehicle monitoring system. English name: vehicle-backup-camera. This system is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. 2. Advantages of the reversing camera: Simple installation. Generally, a standard single-output reversing camera only requires connecting the positive power wire to the positive terminal of the vehicle's reversing light power, and the negative power wire to the negative terminal of the reversing light or to ground (GND). The wiring can be easily understood based on the vehicle model, and the camera can be installed by drilling a hole in an easily accessible position.

I've thought about the shaky reversing camera issue many times, and the most likely cause is your camera not being securely installed. Nowadays, many car owners prefer to install dash cams themselves, but if the mount isn't firmly attached or the license plate light housing is loose, it can easily cause the camera to shake. Once when I was driving on a bumpy road, the screen wobbled like it was dancing – I later discovered it was due to loose wiring harness inside the trunk lid, where the cables would pull the camera with every bump. Here's a lesser-known fact: if the lens angle is adjusted too high, ground distortion becomes more noticeable, making the shaking appear particularly severe. My suggestion is to find a flat surface, engage reverse gear while holding the brake, then go to the rear and wiggle the camera base yourself – you'll probably identify the loose component.

My neighbor also encountered a violently shaking rearview camera before. After troubleshooting for a long time, they found it was a wiring issue. If the video cable running from the trunk to the front of the car isn't secured properly, it will bang against the metal frame when going over speed bumps, causing the camera to shake as well. Now that the weather is getting hotter, extra caution is needed as plastic clips become brittle with age, making it harder to secure the wiring. I once saw a mechanic reroute the cables using zip ties, securing them every 15 centimeters, and the screen immediately became rock steady. As a side note: if the image also shows wavy patterns, it's likely because the power cable is tangled with the signal cable. The ghosting caused by current interference is often mistaken for shaking.

Our old family car had the same issue with the reversing camera. Later at the auto repair shop, they found it was a cracked camera lens bracket – a tiny hairline fracture barely visible to the naked eye that would open up when the car moved. The mechanic mentioned that aged damping rubber rings inside the camera assembly are even more common culprits, especially in vehicles over five years old, as the rubber loses elasticity and fails to absorb shocks. They tested a new camera on the spot using a backup power supply, and the image was rock steady, confirming it was indeed a hardware failure. By the way, if you see snowflake-like flickering in winter, it's mostly caused by oxidized connectors leading to poor contact – check for greenish corrosion spots around the ports.
