You got 3 choices IMO.
1. Leave it as is...
2. Tap the 12V outlet at the front of the vehicle (which is switched).
3. Tap the 12V outlet in the rear of the vehicle. Wrangler's with the premium sound system have a 12V outlet in the rear. I hear that even if you don't have the 12V outlet, the wiring is still there behind the passenger side panel. The only issue with tapping that power source is that it is always hot. So if you tap it, your camera will be on 24 hours a day, 7 days a week. Not sure what kinda of draw it has (battery wise), but it is something to think about. I also don't know if the camera would ever overheat.
I do need to double check that rear outlet. I know that on my Libby, I could run my air compressor without even putting the key in the ignition from the rear outlet and I thought my Wrangler was the same way.
I'm sure there is another switched power source to tap, but I don't know where it would be.
