With all the F&^ktards on the road, I was thinking of adding a dash cam system to my daily driver.

All the systems I have found just kind of sit on the dash. I am really looking for a system I can install (runs off the car battery) and is hidden. Front and rear are the most needed, but side would also be nice. Audio recording is not necessary, also don't really need GPS.

Does anyone know of a system? My net search did not yield much
