How to fix a rear camera for the car?
Car rear view camera help when car parking or car reverse,it is work together with an monitor as set.First,the car camera need to install outside the car, usually at the rear of car, so it is must be water proof.If no water proof funciton,when rainning or washing the car, the camera will burnt down.Second, the night vision function also important, when parking or reversing in the night, the back up camera helps a lot really, if the camera with night vision function,it is helps a lot.As for me the car camera scale line( some body call distance line) is not so important,it is only a reference line,not so acurate, but some people also like it,that's depends.
