And brightness on sunny days?
I received a high definition 2 camera system with a 7" monitor for my Tractor but may use a dash/backup system that uses a 12" rear view mirror for the monitor. Works great in the wife's car. The backup camera can be mounted with magnets to cover any area needed. The dash cam camera has just a little adjustment. With a touch-screen mirror, you can toggle between cameras or also to plain rearview mirror.
