We also use Teams, but as far as I know there is no official standard from MS that includes certification. I came across the Logitech camera on a Microsoft website where it was one of the very few that was Teams ready - whatever that may (or may not) mean. Works without any problems with Teams.

This is an old question but for those considering the purchase: Have regular meetings with it without any problems and all key functions etc. work.

The device connects to the system via HDMI and becomes an "external microphone with camera and loudspeaker" - all configurable in the system settings. This should make the device compatible with Teams.
As far as I know, it is not clear what will happen with Skype (only because one licence has expired) and there are certainly other alternatives besides Teams from MS.
We use https://gotomeeting.com - it works perfectly with ConferenceCam.
