Heh, I do follow Linus Tech Tips, and shared their hate of subscriptions and almost bought a Ubiquiti g4 door bell they recommended because I didn't want a subscription, didn't want my video uploaded to a cloud, and wanted to keep everything on premise.

Sadly unlike their Ubiquiti APs, where you can host the software on any hardware (even a Pi), their doorbell requires their hardware. Last thing I want is a security system that dies with whim of some random manufacturer.
