I received some feedback from a former colleague of mine below, I told him I would forward it along. I hope this helps. Thank you.
Attended a briefing last week here in Ottawa with SharpsAV featuring the 50+ Inch Surface Hub. Very nice. The camera switching was not working that well, as the presenter stood too close to the screen. Perhaps the product could be enhanced by tuning the proximity sensor so presenters that are close could be switched to. Interesting to see if the HDMI PORT also supports switching. Hope your time is great!â€
