All the options suck or are crazy expensive or both, but I have a mix of Reolink, Annke (Hikvision rebrand), and Eufy RTSP-capable cameras. I have a PC with Blue Iris NVR on it. The cameras have SD cards as backups.

Nothing goes out to the cloud. The cameras are blocked from the Internet. I have an alert set up and I've never seen the Reolink or Annke units try and reach out.

If you have a lot of money to blow, buy a complete Ubiquiti setup. It is fairly set and forget. I got burned by Ubiquiti with a previous NVR setup and premature obsoletion so I refuse to use their cameras anymore.
