For this, I would consider UniFi Protect. Their doorbell cam is nice, their other cameras are nice, their software isn't the worst by a mile.

With some simple detours, you can set up a Protect system -- cameras and "console" (NVR) -- to operate completely independent of the cloud, or altogether isolated if you like. Attractive devices and family-friendly. Homekit compatible via an excellent Homebridge plugin.

Not necessarily the cheapest, but, again, there are no recurring fees, either, as there would be for much equipment of similar quality.
