So, I'm a car dealer, so I switch cars a lot. Even the car that's "my" car usually changes at least every few months. I've got Viofo cameras hardwired in my cars that I actually intend to keep, but I would like to find something that I can easily switch between cars. I would like if it had some kind of interior facing camera too to give me a half-assed rear view without having to put a camera on the back, but I would consider just a front view. What should I be looking at?
