Audio/video bar

Audio/video bars provide your laptop with a camera, microphone, and speaker to connect with those online, record content, or both. To find a room with this feature, filter room search for “Audio/Video Bar”

The polycom studio product is shown as the current choice for providing an Audio/Video Bar.

Connecting your device

Unlike other microphones and cameras in classrooms, the Audio/Video Bars work independently from the room control system. They draw power from the pedestal, and signals are provided directly to your device via the red USB cable.

  1. Connect the red, rectangular USB cable found in the cable cubby to your device running Zoom (or whatever software you plan to use to connect to those online or record content).
  2. Select “Polycom Studio Video” for camera in your software.
  3. Select “Polycom Studio Audio” for both microphone and speaker in your software.

Frequently asked questions

What is the range of the microphone?
The range of the microphone at full quality is 12 ft. It often picks up audio from beyond this range but quality drops off and can be affected by differences in room acoustics, competing ambient noise, and orientation of the device to the active speaker.

How can I adjust the volume of those online in Zoom?
In Zoom’s Audio Settings, use the slider for speaker to adjust how loud those online are heard in the classroom. Then click the “Test” button to confirm that the chime is at the right level. This is somewhat hidden to provide a consistent experience each time you use the same setup/room.

In recent testing, we’ve found that adjusting your computer’s system audio (perhaps by a keyboard button) may not change the outgoing volume in zoom and only adjust audio sources from computer audio, such as web browser content or other software.

What is the camera range and quality?
The camera’s FOV is 120 degrees when zoomed wide, has a 5x zoom, and is capable of capturing a 4k resolution (typical use results in 1080p or 720p as most communication platforms, including Zoom, currently support those resolutions).

Will this device work with my tablet? What about my laptop running Linux? 
At this time, the Polycom Studio is compatible with devices running Windows 7 and newer, and Mac OS X 10.13 and newer.

Can I turn off the speaker tracking feature in the camera to have a fixed or wide-angle shot? Speakertracking is left on to provide a consistent experience across all rooms with an Audio/Video Bar at this time.
