Description
DS-4CU is a device that helps to communicate between the microphone system and PTZ
camera to provide a close-up view of the active speaker in a meeting/conference room.
It synchronizes the microphone system’s status(active microphones’ ID) and controls the
camera to move to the corresponded speaker by the preset position with the preferred layout,
overlay, and background.
When paired with an AREC media station, It could also control the station’s theme when a
microphone is activated/deactivated.
