I just went down this road last week. Installed two Wyze cameras. Both are in the dash area - one faces out the front windshield and the other into the coach.
I have sound and motion alerts turned on for the interior camera. Both are plugged into 12v under the workstation tray.
Currently I have the interior camera looking at a 4-zone thermometer so I can see the temp (inside, outside and both water bays).
So far so good.
