We personally use this one for our Toyota Land Cruiser. It is pretty good and it has pretty good quality video. You can of course see the license plates easily in case of an accident. You can configure it to start recording when you start the car and then it automatically stops recording and "shuts down" 2-3 minutes after you turn off the engine.
