I have been setting up a low cost home IP camera solution recently as well. I have also found like others mention, although some of the hardware is OK, on the software side all IP cameras that I have looked at are garbage. hacky linux firmware, needing apps and cloud accounts to config, etc. I also found zoneminder and shinobi not that great either, I've ended up with a "simpler" setup using the basic "motion" Linux motion detect program, and using Jellyfin to view the video files created. So far the "least worst" of the low cost IP cameras I have tried have been TPLINK TAPO.. once they are configured for onvif and IP set by tying to mac address, they can be blocked from the internet access at the firewall and work fine standalone. The only non-TPLINK app I have found that can work with the PTZ mode of the TAPO C210 is the proprietry ONVIER android app.
