Acoustic Fence Technology

RealPresence Group Series systems feature a technology that uses standard Polycom microphone arrays
to build a virtual fence around a user or multiple users. The audio is automatically muted when all sounds
originate outside a boundary. If a speaker is talking inside the fence, the volume is not altered, but sounds
outside the fence are lowered by 12 dB. Once the speaker leaves the fenced area, the audio is muted.
Note: Not Supported on RealPresence Group 300 or 310 systems
Acoustic Fence is not supported on RealPresence Group 300 or 310 systems.
In addition to the primary Polycom microphone array, one or more fence microphone arrays are
required.You can use up to four microphones with RealPresence Group Series 500 and 700 systems. The
boundary radius can be two feet to several feet around the following Polycom peripherals:
● Polycom microphone array
● Desktop microphones
