They definitely have Meraki MRR envy but nothing they've tried so far has really stuck. However, aside from network gear, every product line is an island that does not interop with anyone else's products. UniFi Protect only runs on their NVRs and "Dream" routers and only works with UniFi cameras. The wireless cameras only work with Protect because otherwise there's no way to get them on the network. Once a camera is paired to Protect, you cannot get a standard RTSP stream directly from it (but you can restream RTSP from Protect). They've got a Doorbell camera that doesn't send ring notifications or video to HomeKit / Alexa / Google Home. There's hack-y stuff to make Protect work with standard RTSP cameras. And a HomeBridge plug-in to get HomeKit. But it's all subject to breakage and YMMV. All that said, Protect is pretty great. I'm a (mostly) happy home user.
