There are tons of various kinds of cameras. The price can differ significantly. Personally, I have bought a bmw backup camera last year. Thus, if you look for that brand, the choice is easier – I will definitely suggest to look for any of bmw rear view camera. If you think about different one, below are important issues that you should consider.
The rear view camera seeks to greatly support function of standard car mirrors. This allows to detect more and at better angle. Definitely, this raises the comfort of driving as there is no more need to be bothered about a blind area any longer. Additionally, proportion as well as distance of the view in typical rear view car mirrors often are distorted. Doubtlessly, rear camera will improve driving safety. Various studies have already confirmed this. This is why I think that it is useful to invest in such camera.
