Well, a few months have gone past, I thought I’d share my experience with you, in case it’s useful. If it’s not, no problem, just ignore my post and enjoy the rest of your day.
My spec is, internet connectivity, local storage, HAOS “compatible”, no subscription.
1: My first video doorbell was one of these generic Tuya compatible ones:
Frankly, it was useless. Poor WiFi connectivity, 5-10 seconds lag, poor image quality at night.
2: My second was this Arlo Essentials one:
Better. Decent WiFi connection, NO WIRES, because it has a rechargeable battery. Still very laggy though.
3: My third was one of these Reolink WiFi ones.
You may notice, this project is starting to get a little expensive. Maybe I can spare you some of that.
OK WiFi connection but it kept “unpowering” itself. It would just; die. Then later, come back to life. It didn’t matter what I tried to fix it. GREAT Home Assistant integration, worked well with Frigate and with Agent DVR, MUCH less lag. However, this tendency to go to sleep eventually got the better of me so.
4: I bought the POE version of the Reolink one and had an electrician run a network cable to it, where the doorbell power cable had been (20 years ago I would have been up for scrambling around in lofts but, those days are behind me). It’s SO good, I never think about it. I can record video onto a local NAS, snatch snapshots from it, use 2 way audio to chat to the person at the door. Highly recommended. UPDATE THE FIRMWARE to the latest version.
