I believe the Pro (or whatever they call the highest trim nowadays) supports USB4.

I make use of Reolink cameras with Frigate (mix of PoE and WiFi) and haven’t had any issues with the smart home integration. The only issue I’ve had is with some RLC-811s (and a few other outdoor ones) where water gets into the reset cable and the camera essentially starts boot looping. Seal off those cables and you should be good though.

I’m shocked nobody has mentioned it, but the primary advantage of Zigbee2MQTT is the ability to run Z2M on a machine different from HA. ZHA unfortunately doesn’t allow for this, which is a shame because my Z2M box (RasPi) is centrally located but my HA box is not.
