I wrote a little about my switch to this setup, if it's useful: https://senryu.pub/afternoonrobot/articles/replacing-unifi-v...
Edit: doorbell-wise there are a few models that would work with this setup but I don’t have one at the moment - my doorbell wiring is a really weird voltage and I haven’t gotten around to fixing it yet.
This is great info, thanks!
Arlo does good from videos I've seen shared - I had the V1 they came out with and the battery life was terrible - but I did notice some sort of open source license on the router thing. Not sure it's still a thing, and I think the price is higher, and the battery life is better, with newer versions - but may not be amazon servers?
Arlo looked good too but they were pretty pricey compared to Ring. I'm not that happy that Ring is associated with Amazon, but they do have quite a few privacy settings when configuring them. I download my videos from Ring almost daily and store them in my own encrypted cloud storage, so unless Ring keeps a copy after they are deleted then law enforcement would likely need to ask me for a copy.
I've personally had a mostly good experience with Ring. If you want 4k videos and long-distance night mode then I would avoid them and go with Swann PoE 4k bullet cameras if you can find them on sale, or another brand since they are just re-branded cameras.
Years ago my extended family bought one to monitor a remote camp. I created a little PHP script that would grab the latest images uploaded via FTP and make a photo gallery. Set up was difficult but it worked reliably. They have a Ring now ¯\_(ツ)_/¯
