Google Nest is a privacy nightmare, Ring is even worse. Amazon employees will just randomly access your video feeds, in fact there is a lawsuit about it right now. My go to is Ubiquity UniFi doorbell. It stores the video data locally on a device in my network, and there’s no remote access for them to get into it. It sends alerts to my phone which can be answered like a phone call. The only annoyance I have with it is that it still doesn’t have a time-based “snooze” function to disable notifications for a set time, so when someone is mucking around in the front yard for a few hours I just toggle off notifications so it doesn’t blow up my phone. Caveat with this system is you do need an additional Unifi device in your network to store the footage, but it does not have a monthly fee which is super nice.
