How to Deal with Water Fog in a Reversing Camera
2 Answers
Wipe it clean with a dry cloth or tissue, then use a hair dryer to blow air at the camera for a few minutes. Alternate between cold and hot air while blowing to address general water seepage issues. If the camera is not sealed properly, remove it for treatment. After removal, dry it thoroughly first, then apply sealant to prevent water from entering again.
A few days ago, I encountered an issue with my reversing camera getting fogged up due to water ingress. After driving home in heavy rain, the screen was completely blurred when I reversed, and I almost hit something. I immediately stopped the car and used a clean microfiber cloth to gently wipe the outside of the camera to prevent water droplets from remaining. Then, I noticed moisture inside the lens, so I parked the car in a shaded area and turned on the air conditioning, setting it to cold air and directing it at the camera for about half an hour until the moisture evaporated. If you're in a hurry, you can also use a hairdryer on the low cool setting to blow air at it from a close distance, but avoid using hot air to prevent plastic deformation. After drying, test the reversing function to ensure the image is clear. Upon checking the cause, I found that the camera's sealing adhesive had aged, making it prone to water seepage. Since then, I've avoided using high-pressure water jets directly on the camera during car washes and regularly inspect the sealing ring. Poor visibility while reversing is very dangerous, as safe driving relies heavily on this feature, so I recommend keeping an eye on the camera's condition regularly.
