What Causes Interference Stripes in the Reversing Camera?
2 Answers
The reasons for interference stripes appearing in the reversing camera are: 1. Circuit malfunction; 2. Poor connection of the reversing camera trigger wire; 3. No voltage change at the video connector; 4. Damaged camera. The solutions for interference stripes in the reversing camera are: 1. Replace the circuit; 2. Reconnect the reversing camera trigger wire properly; 3. Replace the camera and video connector. The reversing camera, also known as the parking assist system, reversing visual system, or vehicle monitoring system, serves to: alert the driver about surrounding obstacles, help eliminate blind spots and unclear vision, thereby improving driving safety.
As someone who frequently goes on self-driving trips, I've encountered several instances where the reversing camera displayed snowy stripes. The most fundamental cause is usually signal interference, especially when the power cables of the vehicle's equipment are placed too close to the reversing camera's wiring. Last time, after installing a dash cam, the wiring wasn't properly routed, and the entire rear camera image was filled with wavy lines. Another common issue is when the camera lens gets covered in mud or isn't sealed tightly, allowing moisture to seep in, which happens especially often during the rainy season. Loose wiring connectors are also a frequent problem; for example, in my seven-year-old car, repeated opening and closing of the trunk has loosened the wiring. I recommend checking these three areas: clean the camera lens, inspect whether the wiring is properly laid out, and reconnect the tail wiring harness. If the issue persists, it might be time to consider whether the camera itself is faulty.
