Ubiquiti NVR Instant kit is a great value, and you get 24h local recording without a subscription. And it is well supported with Home Assistant.
Some of the UniFi cameras are amazingly expensive though, $500 for an outdoor 4K camera is hard to swallow. But if you can swing it, you will not regret the investment.
I already have other UniFi gear for networking and it was natural to add cameras to the system.
Apparently UniFi Protect works with 3rd party cameras if they support ONVIF but I don’t know of any yet.











I have the same TV. It doesn’t specifically help you but using HDMI 2.1 sources works fine for 4K HDR 120Hz and VRR. I have too many devices (Xbox Series, PS5, AppleTV, Switch) so they are routed through a GUIDE3 switcher.
So I would think it is the DP converter or the HDMI cable not really being 2.1.
