Seriously agree with the POE option.
(1) I would MUCH RATHER have an RJ45 network port than use Wifi. (I keep as many things OFF wifi as possible as it is a contended network so save that for tablets etc & it’s just reliable!)
(2) POE would be awesome. I use it wherever possible. Converting from 48v to 12v – could use the following buck device from Aliexpress I guess. #us3-$4.
