One of the slick things you can do is add machine learning to it and have motion alerts based on what is detected in the video (person, car, bear, those are some of the built-in options). That looks pretty slick.

I'm trying to recall, but maybe someone else can answer: do the UniFi cameras stream RTSP directly still, or do you still have to run their controller and re-stream it?

Log into the WebUI, set it to whatever the non-Unifi Video mode is, update the firmware, repeat, set your RTSP config, good to go.

I use Blue Iris with my Ubiquiti cameras. Works like a champ.
