The user of a Cisco TelePresence MX300 wants to control the far-end camera of any video conference participant. Which control device and function is used to control the far-end camera?

The TRC5 remote control arrow keys navigate menus and control the local camera; the MX300 is a touch-based system and TRC5 is not the primary interface for initiating FECC.

On the Cisco TelePresence MX300, tapping directly on a participant's video image in the touch control interface activates FECC options for that specific participant. This brings up camera controls that allow the local user to pan, tilt, and zoom the remote participant's camera, which is the correct and supported interaction model for touch-based endpoints.

The Touch Control Conference functions menu provides general call management options such as muting and disconnecting participants, not the specific per-participant FECC functionality.

The TRC5 home key returns the device to the home screen and has no functional relationship to far-end camera control.
