Have been running my own NVR for decades, most of it with the motion project. Recently started switching things over to Frigate and I am impressed with it as well. The Corals are worth the money. I run two of them on my setup (6 to 8 1080 cams at any given time) and quite pleased with it.
The default models are great at detecting humans, but not so much cars/wildlife. I definitely plan to try and expand on that in the near future.
