There are many different types of cameras. The quality could differ a lot. Personally, I have bought a bmw backup camera a while ago. In consequence, if you are interested in that brand, the choice is easier – I would absolutely recommend to choose any of bmw rear view camera. If you think about different one, below are important factors that you should consider.
The backup camera seeks to highly support function of ordinary car mirrors. That allows to see more as well as at better angle. Undoubtedly, this raises the comfort of parking as there is no more need to deal with a blind area anymore. Additionally, proportion as well as distance of the view in typical rear view car mirrors often are distorted. Unquestionably, rear camera can contribute driving safety. Some studies have already confirmed that. Therefore I believe that this is worth to have such camera.
