I do have a camera with ‘tracking’, but it is tracking the face of the presenter (or multiple presenters on average in some cases).
Logitech QuickCam Orbit AF:
There is no regular camera that will track voice that I know of other than the very expensive option from Microsoft *but* that was not working with Connect last time we tried
There are typically options from Tanberg, Polycom and Sony that work in a larger conferencing setup and actually track to the microphone location that is detecting the sound (thousands of dollars)
This is not a Connect limitation really, it is a camera limitation at this time
