So I have a Raspberry Pi 3 - B sitting around, doing nothing. I'd like to build a 'petcam', but I don't know the first thing about it. My questions to you good people are:
1. what kit do I need?
2. can one Pi control multiple cameras? Ideally, to have say, four cameras displayed simultaneously on one screen?
Note that the Pi will be too far from my switch, so I'm going to have to add some sort of reliable wireless connectivity. Oh, and a 4K camera would be nice, but I suppose that's too optimistic?
Finally - my preference is for CentOS or RHEL as that's what I know, but if this can only be done with Ubuntu or one of its derivatives, then that's fine.
