I just got the three-pack of TC85 cameras.  They look and feel substancial.

I successfully connected them to the Tapo App.  But getting them recognized as ONVIF cameras on the network (so I can add them to my Synology NAS) isn't working.

Of course, I went to Settings/Advanced/CameraAccount and created a userid/password, and acknowledged the warning.

But when I try and have Synology Survellience scan for ONVIF cameras, while it does find my existing ONVIF cameras, it does not find my new TC85s.  I thought maybe having an SD card in might help, but no.  I removed the SC card, but still no.  The Change Account note says

        Tapo Care works best with ...  At this point the NVR recording will be disabled.

So maybe I somehow need to get it enabled.  But there is no SD card installed for me to remove to have the camera enable it.

I also tried using the Android app IP Cam Viewer Basic, which also finds my existing ONVIF cameras but not the new TC85s.

Suggestions?  I'm pretty sure this is a user error ...
