Happy it works for you!
I’m running it on arch so that I never have to go through big upgrades. Been over 5 years now - so far, so good!
In regards to docker - it’s just a container. You can make any executable run a container. I quite like a lean system myself, though.
I only have the indoor one, but Reolink is fine. Used it as a baby cam. No cloud bs, supports an rtsp stream. App has gone downhill, but due to rtsp I sort of don’t care.
