Camera Boffins - Would like your input

Hi all,

With the recent post about ring etc, I think some people may want to know similar answers to what im curious about. I had replaced my system with Eufy ages ago. Cameras are great, but doorbell is pants.. its the delay in the app.

So i was thinking about keeping my camera system for now, but looking elsewhere for a doorbell. Ive read bits and pieces about Reolink and other doorbells which supposed to be very good.

I suppose what im wondering is if I make the shift (or even is possible with my eufy ones) is there a way to record everything from every camera locally, on like a raspberry pi server etc. I know i have the homebase 2 with Eufy, but just thinking long term would rather try and have something networked

any idiots guides etc showing whats avilable?
