LifeSize Icon Video System Guide
32
If the camera does not show video, ensure that the camera is connected to the LifeSize system with a
camera cable to the appropriate camera input or contact your administrator.
Verify that the blue LED on the front of the camera is lit, which indicates that power is active, and reboot
the system if necessary to verify that the camera turns on. If a system reboot does not resolve the problem,
you might need to reapply power to the camera.
Administrators can also configure preferences for the following camera conditions:
•
Anti-Flicker
•
Auto Exposure
•
Brightness
•
White Balance
Read more about these settings in the online help available when you access the video system with a
browser.
Packet Loss
Packet loss can result in noticeable video or audio performance issues and can be caused by signal
degradation over the network medium, oversaturated network links, corrupted packets rejected in-transit,
faulty networking hardware, and misconfigured system drivers or network applications. Refer to the
technical note
Troubleshooting Packet Loss
for steps you may take to address packet loss.
Display Issues
If data does not appear on the display, ensure cables are properly connected on the display and that the
display cable is connected to the HD 1 output on the back panel of the codec.
If the video image and user interface appear washed out or too bright, examine your HDTV input settings
to make sure the HDTV has the appropriate resolution. Some HDTVs, particularly plasma displays, allow
you to configure the native resolution of the input device from the HDTV administration interface.
Administrators only
: Access the video system from a browser and navigate to
Preferences > Video
to
ensure that the display resolution is correct for your display.
Problematic Sound Quality
If the far side is hearing an echo or distortion, the microphone connected to your LifeSize system may be
too close to the speakers. Repositioning the microphone may solve this problem.
Muffled audio reception from the far end may be caused by highly reverberant rooms. If you are
experiencing poor audio reception, add more sound absorbency to the room and speak in close proximity
to the phone or microphone.
Degradation in the audio quality can also be caused by faulty microphones or dust and debris on the
microphones. Do not use any kind of liquid or aerosol cleaner on LifeSize devices that include
microphones. A soft, slightly damp cloth should be sufficient to clean the top surface of the units.
