A few years ago, I didn’t know anything about cameras dedicated for cars. And even if I knew anything, I cannot remember that at the moment. Nevertheless, such cameras became very popular. Many people friends have either installed such camera in a car, or purchased a car thatalready have camera. On the internet there are tons of threads where people keep on discussing different questions regarding the cameras, e.g.: which one to purchase, is it smart to purchase this, how to install them, and so on.
