How do they verify that I'm in the EEA? Do I need to sign up through a VPN when I register Windows or do I just specify an EEA country during the install?
TBH the only way I've found around this is a full CCTV solution monitoring my perimeter, the doorbell can just identifies those who come really close and push the button.
A doorbell camera should be viewed as for convenience on the door. If you want adequate security you really need to get a dedicated security focused solution.
