How to Deal with Fogging in Car Rearview Camera?
4 Answers
A rearview camera is a type of car camera installed at the rear of the vehicle. It works in combination with a display screen installed inside the car to form a complete rearview imaging system, allowing the driver to see real-time video images of the area behind the car when reversing. The solutions for fogging in a car rearview camera are as follows: 1. Surface fogging: Simply wipe it clean with a dry, soft cotton cloth. Generally, avoid using cleaning agents. 2. Internal fogging: Remove the camera and place it in a relatively dry environment. Usually, the moisture will disappear after some time. 3. If necessary, remove it to blow dry the water, then apply some glass glue at the water inlet. Wait for the glass glue to dry for about half an hour before reinstalling it.
My car's reversing camera keeps fogging up, and I encountered this issue last autumn. At first, I didn't pay much attention, but I almost hit something while reversing in the rain, which gave me a scare. Later, I found out that the camera's sealing strip had aged, allowing moisture to seep into the lens. I wiped it with a soft cloth, but it didn't help much because the fog was coming from inside. A friend suggested buying a car-specific anti-fog spray that forms a protective film on the lens. After trying it, there was a noticeable improvement—one application lasts for one or two months. Preventive measures are also important: after parking, open the trunk to ventilate for a few minutes to avoid moisture buildup. Placing some inexpensive desiccants in the corners of the trunk can also help. Remember, if the camera fogs up, don't force yourself to drive—stop and deal with it safely first.
I have experience with foggy cameras, which is often caused by condensation due to large temperature differences or high humidity. If the internal circuit of the camera isn't sealed properly, moisture gets in and causes fogging. I've tried DIY methods, like gently cleaning the edges of the lens with alcohol swabs, and replacing the seal if it's damaged—it's cheap. There are many anti-fog sprays available on the market that can prevent water droplets from forming. A more fundamental solution is to check the vehicle's overall ventilation system; if the air conditioning vents are directed toward the trunk, it might worsen the issue. Poor rearview visibility is dangerous, especially in parking lots or narrow roads. Regular inspection and cleaning of the camera are low-cost but crucial for safety.
A foggy rearview camera can make it impossible to see clearly while reversing, increasing the risk of scratches or collisions. If you notice fogging, don’t move the vehicle—stop safely and address the issue. Wipe the exterior gently with a clean microfiber or eyeglass cloth, being careful not to scratch the lens. For internal fogging, use a hairdryer on a low setting from a distance for a few minutes to dissipate the moisture. To prevent fogging, regularly check that the camera is securely installed and properly sealed, as gaps can allow moisture to seep in. Be especially vigilant during rainy seasons and perform a quick inspection before driving. If fogging persists, it may indicate moisture in the wiring—consult a technician for a professional inspection to avoid major issues.
