With one low res camera I ran it in a Debian vm with 4gb of Ram and two cores no problem. Once I had three 4K streams, I bumped it up to 16gb and 10 cores, only cause I wanted a hi-res live view, but I’m sure it would do fine with less with low res live view. Have been running it in a vm for two years now, no issues. Tried a bare metal install and lxc. Keep coming back to vm for the adaptability. Adding GPU and npu through lxc always made issues for me, but passing through to a vm is pretty well supported and documented, I think the ease of use outweighs the additional resources used by the vm. Plus I have read it’s not best practice to run docker inside an lxc.
