What to Do When the Rearview Camera Gets Waterlogged?
4 Answers
If the rearview camera gets waterlogged, it is recommended to replace the camera to avoid affecting its functionality. Below is more information about rearview cameras: 1. Introduction A rearview camera is a type of automotive camera installed at the rear of the vehicle. It works in conjunction 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 vehicle while reversing. 2. CCD Imaging Process: When the silicon semiconductor photosensitive elements coated on the surface of the CCD capture photons, they generate photoelectrons. These electrons are initially stored in the insulating layer beneath the CCD, then exported serially to the analog-to-digital circuit by the control circuit, and finally processed by imaging circuits such as DSP to form an image. 3. Classification: Vehicle rearview cameras include: night vision rearview cameras, license plate frame-mounted rearview cameras, semi-license plate frame-mounted rearview cameras, drilled cameras, and external cameras.
I encountered a problem with water ingress in my reversing camera and managed to fix it myself with good results. First, stop using it to avoid short circuits, then carefully remove the camera to inspect the water entry point. Most likely, it's due to a deteriorated sealing ring or water seeping through installation gaps. Use a hairdryer on low heat to dry out the moisture or let it air dry naturally for a few days. I've tried this several times, and once the lens is clear after drying, it's fine. If the internal circuit is corroded, you'll need to replace the camera to avoid future risks of blurry images while reversing. Usually, park away from waterlogged areas, and during installation, choose a good location, such as the inner side of the bumper, avoiding too much exposure. When cleaning the lens regularly, avoid spraying water too forcefully, and keeping it dry can prevent repeated water ingress. If it can't be repaired, buying a replacement part for around 100 yuan on Taobao and installing it is also economical.
After my reversing camera got water inside, I feel safety is a big concern as the blurry image during reversing makes it easy to scrape or hit objects. My suggestion is to immediately stop using the reversing function and rely on the rearview and side mirrors for additional observation. Open up the camera to clean water stains, gently wiping the lens and connectors. If water has penetrated the circuit board, it must be sent for repair or parts replaced to prevent further malfunctions. Pay special attention to the camera's sealing during the rainy season, and avoid installing it in low-lying or frequently splashed areas. Such minor faults may seem trivial, but if not addressed promptly, they can lead to misjudging distances while reversing. It's advisable to regularly check the vehicle's electronic equipment. Simple maintenance can save a lot of hassle.
I have handled several cases of water ingress in rearview cameras, usually caused by loose sealing rings or cracks in the camera housing. The steps involve disconnecting the power, removing the camera, and drying it with a hairdryer—letting it air dry for half a day is even better. Ensure no water stains remain on internal components to prevent circuit short circuits. When reinstalling, reinforce the seal to prevent future water ingress. If the image returns to normal after repair, it's acceptable; however, a damaged lens requires replacement with a new part. Simple maintenance can avoid such issues.
