LifeSize Icon Video System Installation Guide
13
Follow these guidelines to obtain the best possible performance from your audio output devices:
•
Use only speakers that provide a flat frequency response and a linear output signal.
•
Position all speakers at least five feet from the microphones, regardless of the type of device that you
use.
•
Adjust the speaker volume to 40-50% of its maximum value. Speakers often produce distorted output
when the volume is set to a value that is greater than 60% of the maximum, and distorted output can
cause acoustic echo. Read
Acoustic Echoes
for more information.
•
Avoid Dolby or surround sound speakers, which can change their speaker signal and generate
echoes.
Camera
In most cases, LifeSize recommends that you mount the camera in coordination with the display to provide
as close to an eye-to-eye experience as possible. Follow these positioning guidelines:
•
Position the camera in the center of the primary display.
•
Place the camera immediately below or above the primary display. In most cases, the position
immediately below the display is preferable.
•
Place the camera far enough from the participants so that everyone is captured within the camera’s
field of view (70 degrees for LifeSize cameras).
Video Display
The video display that you choose for a conference room depends on many factors. One important
criterion, though, involves making certain that the display’s input matches the video system’s output.
Consider whether a display provides participants with a comfortable experience. The following factors
influence the optimal size of a display:
•
size of the room
•
participants’ distance from the display
•
level of required detail
•
budget
If the camera is centered on the top or bottom of the display, LifeSize recommends that you position the
display so that its top is as high as the forehead of a typical participant.
Cables
The LifeSize video system is shipped with the following cables:
•
Power cable – Your LifeSize video system ships with a 2-meter power cable. Use an extension cord for
longer runs.
•
Ethernet or LAN cable – The video system ships with a 3-meter RJ45 Ethernet/LAN cable. You can
substitute a longer Ethernet cable (Category 5e, at a minimum): up to 100 meters (328 feet).
