I have a Reolink PoE camera. It’s plugged into Home Assistant, and some setting in the integration had it phoning home constantly looking for updates. I turned that off and now it only connects outside of my network to sync the time.
The camera has survived outside for a few years now, so no complaints.

Home Assistant for viewing

Heads up: by default, HA does not show real-time, full-framerate video - just a snapshot that updates every 10 seconds or whatever. As with all things open source, there is a way to fix it, but you have to faff around. I haven’t bothered yet, but it’s on my list.

It’s always bothered me that someone went and called their band “Death”, but I find it difficult to articulate why.
