For anyone who wants a setup like this but the nice notifications and quality of life capabilities (recordings, easy remote access for family), and are ok being on Apple infra (end to end encrypted) -

ONVIF camera (or one compatible with Scrypted) Block WAN (ideally, VLAN) on the cheap cameras Home computer to run Scrypted AppleTV (for Apple home bridge)

This is what I moved to after getting away from Ring and it works quite well. Reolink cams, old desktop, and an hour of setup.
