I have two Tapo units at home, they seem to be working fine without an internet connection.
I created a new subnet and an associated WiFi SSID for it, connected the Tapo cameras, and set them up to act as RTSP cams. I then firewalled the subnet off from anything other than my Frigate NVR server and gateway. They still work fine, they are streaming video to Frigate without complaint. Maybe because they have DNS from my gateway still? (I should probably block that off, it's a common data exfil vector).
Very annoying that internet connectivity is required for initial setup, I'll agree there. They could have just had a bare bones web interface.
