How to Deal with Water and Fog in the Reversing Camera

First, wipe the camera lens clean with a dry cloth, then use a hair dryer to blow air at the camera. Remove the camera and dry it thoroughly, then apply sealant for reinforcement. Seek professional repair at a maintenance shop.
Last time I noticed condensation on the rearview camera, the entire screen was blurry, which made me uneasy while reversing. Actually, condensation is mostly caused by poor sealing or large temperature differences. I quickly wiped off the surface moisture with a clean, soft cloth, parked the car in a ventilated area to let it dry naturally, and avoided using a hairdryer with high heat as it can easily deform the plastic. The next day, if there were still water droplets, it might indicate that the camera housing seal has aged, requiring a new gasket or resealing. When washing the car, be careful not to spray water directly at the camera area, as high-pressure water jets can force water inside. During regular maintenance, it's advisable to check if the camera is securely installed to prevent issues and ensure peace of mind while reversing.
The most common cause of water condensation in cameras is the failure of waterproof gaskets or cracks in the housing. When handling it myself, I first clean surface dirt with a slightly damp cloth, then turn on the car's air conditioning with warm air to help evaporate the moisture. Observe for a few days; if condensation repeatedly occurs, pry open the housing to check if the gasket is damaged. Simply buy a new gasket from Taobao and replace it—no need to waste money replacing the entire camera. Also, avoid parking in environments with large temperature differences, such as leaving the car outdoors in winter. The key point is: timely handling can extend the device's lifespan and ensure clear visibility when reversing.
My old car's reversing camera also had issues with condensation. The solution is simple: first wipe the lens clean with a dry cloth, then drive the car to let the engine heat naturally dry it out. If the seal isn't good, check if the housing rubber is cracked or loose, and reinforce it appropriately with sealant. Wiping it dry immediately after washing the car can prevent the problem from worsening. By sticking to these small maintenance steps, the camera is less likely to get water inside, making reversing safer and more convenient.
