12V is too low. That's going to kill your battery in very short order, even if you recharge every night.
If you're saying that you'll only ever use this feature when you can have it plugged in, then what you're after makes sense. If you're looking to let your battery die every single day and then recharge it afterward, then I would call that very ill-advised.
You said that you had some instances where you could prove you were not at-fault via the cam. Were any of these instances while you were parked? It happens, I know, but getting creamed while parked probably isn't very common. I've been dinged and dented, but I doubt a cam would help me in that regard, based on the orientation of my parking lot.
