Far End Camera Control allows for another user to take control of your camera and use Pan-Tilt-Zoom (PTZ) functionality of the camera. The webcam must have these features for this to work. The host of the meeting is the only user that can request far end camera control.
How to Enable Far End Camera Control
This setting must be first enabled in your Profile Settings.
Once in a meeting the user will select your video and "Request Camera Control".
The remote user will then "Approve" giving control.
After control has been given, you will see the options available in active speaker view for this user.
At any point, the user controlling the camera can give up control by selecting "Give up Camera Control".
