If you want to learn about VLANs and spend some time setting everything up (and more time each time a new device joins your network) then you should go for it.

I for myself decided it’s not worth it for my little home network and instead just use a /16 net and group devices into different ranges. E.g. computers are xxx.xxx.1.yyy, phones are .2.yyy, etc. All unknown devices get a .99.yyy from the DHCP, so they are easily identified.

All public facing stuff is in some Docker container, so there’s at least a small hurdle should something/someone get access.

Cameras are mirrored into Apple HomeKit via Home Assistant, so I can use Apple Home to watch them from afar. Or VPN into my home network.
