There are several reasons for the fuzzy astern camera:

1. At present, the reversing camera on the market are basically waterproof, if we buy a poor camera, then it is easy to seepage into the water, resulting in blurred camera;

2. The camera is used for a long time, resulting in poor photographic effect of the chip;

3. The lens of the reversing camera has dust;
What if the back-up camera is blurry? In the face of dust or dirty things sticky, we can directly clean, if the chip aging caused by too long use time, then you can go to the repair shop for repair or direct replacement; If there is water into the camera, you can try to take a hair dryer to blow on the camera for a few minutes, and then it is best to seal the treatment, to prevent water seepage next time.

Be aware of the camera materials and the number of lenses; Camera lenses are usually made of glass lenses and plastic lenses. Plastic lenses are very cheap, but the imaging effect is obviously inferior to glass. Better quality cameras all have 4-layer glass (all-glass) lenses (4G for short), and 5G lenses. Some manufacturers use inferior plastic lenses, and while these are attractive and cheaper in price, the actual results are not impressive. So when buying cameras, we must not blindly covet cheap, or try to choose the glass lens.
