Why customers complain the blurred image in car backup camera?

Engineers in prevision-for-safety have the ability of hardware develop with their own private mode for camera shell. According to the rearview system supplier China in prevision-for-safety, the use of self-opened rubber ring have the benefit of waterproof in the glass periphery, between the shell and the outlet hole.

 

According to the prevision-for-safety engineers, we can know why so many customers complain the blurred image in car backup camera. The camera in peer is generally used public mode and the way of waterproof is using UV glue (the original state is white solid which turns into liquid under the hot melt gun shot). The UV glue has to wait 24 hours before they can be completely cured when the camera's waterproof ring groove into the water. Generally speaking, factories with business of wholesale car backup camera mirror don't want to use their own production line for solidifying due to this reason. So there still contains water when the UV glue is not completely cured. However, the water was left in the shell when the camera is assembled. Under this situation, the internal heat when the camera is in use. In general, the temperature difference between the inside and outside shell water is not easy to evaporate into water vapor in sunny weather, and then condensed in the glass near the external temperature which becomes water droplets.

 

But when you meet the rain and snow weather and other situation of internal body temperature is higher than the external temperature, the internal water evaporation will turn into water vapor. When the water vapor near the external temperature of the glass, it becomes the water hanging on the glass, caused blurred image which is many foreign customers complained that the camera in the rainy days has blurred image or even the image becomes white after six months (this time the water droplets have completely contaminated imaging chip, so the image completely white). We would know the importance for the high quality vehicle RV backup camera.
