I have the newest Logitech webcam with built in microphone which works great. My wife is in a rehab facility getting her strength back from kidney failure and web do a webex every day. She can hear me fine (nearly deaf she is) and when we she wanted to see our dogs and the cats the long USB cord made moving the camera around easy so in your case you could point it at a screen to show information and hide the rest. There are two lights that show when the camera is on and since it is USB you can unplug it when not needed.
