Adjusting Camera Brightness
Camera brightness refers to the amount of light received through the lens of the camera.
You can improve dim scenes by adjusting room lighting and manually adjusting the camera
brightness. To adjust camera brightness, set the HD Camera Brightness preference in
User Preferences : Diagnostics : High Definition Camera.
Adjusting Camera White Balance
Camera white balance refers to how a camera references the color white, which is a mixture
of all colors. Adjust the white balance when video color appears to be unbalanced. White
balance is affected by the type of light source. To adjust the camera white balance adjust the
HD Camera White Balance preference in User Preferences : Diagnostics : High
Definition Camera.
Adjusting the Camera Anti-Flicker Preference
Lights powered by a 50 Hz power source can produce a flicker that the camera captures and
transmits to the system. If you are using lights powered by a 50 Hz power source and
observe a flicker in the video displayed in your system, select the 50 Hz option in User
Preferences : Diagnostics : High Definition Camera : Camera Anti-Flicker. The default
option is Auto.
Some camera exposure settings designed to be used in rooms lit by sunlight may result in a
flicker. To remove the flicker, increase the HD Camera Brightness setting in User
Preferences : Diagnostics : High Definition Camera.

Display Issues

The following issues are related to the user interface or the display.
Display Failures
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 Display 1 output on the codec.
If the video image and user interface appear washed out or too bright, examine the input
settings of your HDTV to make sure the HDTV is displaying the appropriate resolution.
Some HDTVs (particularly plasma displays) allow you to configure the native resolution of
the input device from the HDTV administration interface.
Poor Quality Display
If the colors on the display appear incorrect, verify that the display cable is properly
connected to the display.
