Not OP, but i've recently set up 5 cameras, 2 more on the way. My system is Ubiquiti with the following hardware:

- UDM Pro

- 24 Port PoE Switch

- 3 G3 Instant (Wifi based Camera)

- 1 G4 Pro (4k Cam, optical zoom, etc)

- 2 G3 Flex (cheaper/simpler option to the G4 Pro for less important areas)

- 1 G3 Doorbell

- 2 Wifi 6 Lite AP

I've been mostly happy with it so far. My only complaint is that there seems to be a semi-common issue with scrubbing timeline history. Downloading the clip works fine, but the websocket driven UI seems to lock up - i suspect it is a UI Software issue.

Aside from their software i've been very happy. Also the cameras, i believe, serve standard RTSPS so if i get fed up with Ubiquiti software i might switch to something standard. Though i'll probably try changing the hard drive (something faster perhaps) or even a dedicated NVR in an effort to make the history scrubbing work better.

Seems like a minor issue that could probably be resolved easily if it was FOSS :/
