I see a whole bunch of Chinese crap all over Amazon and elsewhere that advertise high-def cameras for backup purposes and whatnot. I'm trying to find a good multiple camera system that is truly high def (not grainy). I want to mount a monitor in the cab and have enough resolution to replace the rear-view camera if I wanted to. I mean... my old iPhone 3GS camera/screen from years ago now sitting in a box somewhere looks better than most of the crap out there being sold today.
