I’ve been using the Reolink Doorbell (POE) for the last few months. I use it with both local on board SD card recording and with Frigate. It’s been perfect and the Home Assistant integration is awesome too.
I haven’t tried the FTP feature but have with my other Reolink cameras and that worked as expected.
The Reolink subreddit /r/reolinkcam is great, an employee lurks there and is very helpful.
The rules are easy to follow though and clearly stated at least.
