If nothing’s exposed and it’s all behind Netbird, you don’t strictly need it. I still would, because apps like Vaultwarden’s web vault won’t load without a secure context. A wildcard cert via DNS challenge is a one-time setup. Everything else is optional.


Put the cams on their own VLAN with no route to the internet and let Frigate pull the RTSP streams. Block DNS for that VLAN too, or they’ll keep trying to phone home. Curious what you pick for the NVR side.
