linked to a couple of cameras in my write-up that I use. The USB camera is extremely good quality, the csi is , \"very good\". Not as good as the UVC, but still extremely nice. The nice thing about the UVC camera I chose is that it is a pcb with a wire sticking out of it, so you can very easily just mount it in any orientation just as easily. I screwed it to the front side of the rear view mirror, so it is invisible from inside the car except for the wire running up into the headliner."}}
