I'm connecting the Tapo Camera to a 3rd Party VMS.

Some notes:

- Camera connected over ONVIF Protocol on port 2020 (a bit weird since I think ONVIF protocol is usually over 80 or 8080)

- Motion/Person Detection works fine in the app

- Motion/Person Detection not triggering on the 3rd party VMS

- Live streaming works on 3rd Party VMS

- 3rd Party VMS has an option to manually trigger recording as well as continuous recording. Both option works. It's only Motion triggered recroding that's not working

- 3rd party VMS = Avigilon v7.14.28.4 (It's a commercial product that supports ONVIF Profile S on various other ONVIF Cameras)

- network path = both VMS and camera on the same local flat network under the same router and no traffic is being routed outside, everything is local

- Not sure if relevant, I loaded up Onvif Device Manager and see that all events message have a timestamp of 1970-01-01T00:00:00Z which is consistent with the wireshark capture which I'll paste below

I just recently bought this camera so I have no idea if it used to work or not. I however did see a post where it indicates C100 and C200 had similar issues and that was recently fixed in 2023 September. I am wondering if similar fixes is also applied to the C210
