On the install I got there is just enough room to pop the hatch open when it is down, it doesn't quite actually touch the cam so you can just (I mean just barely but it works) get it open I would post a pic but I'm away from the car right now and will be for at least another month. And this install was not wireless but the guy did it such a way that I don't see any wires anywhere just where they come out to attach to the cam maybe an inch of wires showing.
