No cams at all yet and any that will possibly be used will be RPi and camera module setups put together and configured by me. I haven’t had a virus on my machines in probably over 10 years and I only have linux machines on my network (mine and my wife’s). I have a separate guest network for friends/visitors so nobody else on the network that has NFS running. Everything on my network is configured by me and I manage and configure my router myself.
So, are you against any kind of file sharing on your home network then? Is there something other than NFS that you use that you feel is more secure?
