I bought a camera for the caravan to look to replace the rear view mirror while driving right behind the caravan can. So I see overtaking of trucks, when I am past them in order to then einscheren right again can. In the state of the image ia is very good, but while driving the image is greatly disturbed and sets zeilweise completely. Even with different mounting points for transmitters and receivers, there is no significant improvement. For this reason, there is the point deductions.
