Adjusting Room Lighting; Camera Issues - LifeSize Passport User Manual

Improperly connected or loose cables are common causes of problems with hardware units.
When investigating a system problem, first inspect all the external controls and cable
connections. Ensure that connections are correct and secure, and that nothing is obstructing
the cables. Contact your administrator for information about proper cabling.

Adjusting Room Lighting

You can assist the system to maintain the best possible image quality by altering the
environmental 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
You can also improve dim scenes by adjusting the camera brightness. Refer to "Adjusting
Camera Brightness" on page 29.

Camera Issues

If you are unable to pan, tilt, or zoom a camera that has these capabilities, ensure the
remote control contains three AAA batteries that are in good working condition. Also verify
that no objects are obstructing the sensor on the front of the camera and that the LED on
front of the camera flashes bright blue when you use the remote control to perform a task.
If no video displays from the camera, ensure 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, indicating that power is active, and
reboot the system if necessary to verify that the camera turns on. To reboot the system, refer
to "Power and Connectivity Issues" on page 30.
Using Camera Diagnostic Preferences
You can use the camera diagnostic preferences in User Preferences : Diagnostics to
adjust camera brightness and white balance and correct for some types of flicker that may
appear in the video. Diagnostic camera preferences for camera brightness and white
balance are available only if the selected camera is connected to the codec and Ready
appears as the status for the camera on the System Information page.
