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 device.
If the far-end device has activated Speaker mode where the camera follows the active speaker or is using Best View , you can't control the camera remotely.
You don’t have remote access to any camera presets.
During a call, open the Participants list.
Select the one whose camera you want to control and tap Control camera .
Adjust the remote camera's tilt, pan, and zoom with the camera control buttons. Tap anywhere outside the buttons when you’re done.
