When you're in a video call where one or more of the other devices have a remotely controllable camera, you can control those cameras from your own touch controller or desk device.
If the far-end device has activated camera tracking where the camera follows the active speaker or is using Best overview, you can't control the camera remotely.
You don’t have remote access to any camera presets.
In a call, select the Participants icon in the upper right corner, to invoke the list of participants.
Select the one whose camera you want to control and select Control view .
Adjust the remote camera's tilt, pan, and zoom with the camera control buttons. Tap anywhere outside the buttons when you’re done.
