Front facing dash cam on rear window?

[toonmal]

Just wondered if anyone has fitted a front facing camera to the rear window. I would assume it's pretty simple, using the rear 12v socket, but if you have, pics and fitting would be appreciated

Easier to buy a 2 channel that has front and rear.

But otherwise it is the same effort (but now would need 2 12v ports or a splitter if not hard wiring it).
