Rear Dashcam Ideas

Hi All,

I've been running a Nextbase dashcam in the front for some years now, and am keen to look at a rear. I've just upgraded to a nicer model, and have the option of getting an add-on rear one that plugs into the front.

My issue is, I loathe to run a cable from the front dashcam to the rear. I can't be bothered messing around with headliners and such at the moment, and the install on the front is so clean (there's about 1cm of cable showing from the modified mirror surround) that I don't want to touch it.

I can't use the telephoto lens attachment bit, as mine is hidden behind the mirror.

It occured to me that I could stick the old one in the rear window (it's not old, really, just 1080p instead of 4k) and power it via the 12V boot socket. Of course, remembering to unplug it is going to be a pain, but it seems that (maybe with an auto off) is the best bet.

Any other ideas?
