I have two dcs-6100h for 9€ each that work just fine locally. Good ir night vision, very sensitiv mic and USB powered for trips.

I had an optiplex 3060 micro with 8500t, 24gb ram and 2 ssds idling around 3-5watts.
One of the few options that allow docker conf via labels. Will try it, currently using caddy.
