Lifesize Icon Guide 40
Adjusting Room Lighting
Ensure that the system maintains the best possible image quality by altering the lighting and background
colors of your environment. If light levels are too low, you may consider adding artificial lighting. Indirect
light from shaded sources or reflected light from pale walls often produces excellent results.
Avoid the following:
• Direct sunlight on the subject matter, the background, or the camera lens, which creates harsh
contrasts
• Direct illumination of the subject matter and camera lens
• Colored lighting
• Harsh side lighting or strong light from above
Camera Issues
If you are unable to pan, tilt, or zoom a camera, ensure that the remote control contains two AAA batteries
that are in good working condition. Verify that no objects are obstructing the sensor on the front of the
camera and that the LED on the front of the camera flashes bright blue when you use the remote control to
perform a task.
If the camera does not show video, ensure that the camera is connected to the Lifesize system with a
camera cable in 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
• Auto focus
• White balance
• Lock camera position

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
