Improve Video Quality

Room lighting can affect video quality. If the room is too bright or dark for camera tracking to work properly, you can improve the video quality by adjusting certain settings in the web interface.

Note: The following settings are also available in the RealPresence Group Series web interface. The last changes to these settings are applied for the camera, whether you change the settings in the RealPresence Group Series system settings, or in the EagleEye Director II settings.

Procedure

  1. Go to Camera Settings > Cameras.
  2. Configure the following settings.
    SettingDescription
    Backlight CompensationSpecifies whether to have the camera automatically adjust for a bright background. Backlight compensation is best used in situations where the subject appears darker than the background.
    White Balance

    Specifies how the camera compensates for variations in room light sources. Select Automatic, Manual, or a color temperature value.

    Automatic: Polycom recommends this setting for most situations. It calculates the best white balance setting based on lighting conditions in the room.

    Manual: Use this setting for rooms where the Auto and fixed values do not provide acceptable color reproduction.

    After you set this setting to Manual, fill the camera’s field of view with a flat white object, such as a piece of paper. For best results, the object should be uniformly illuminated with light that is representative of the room lighting that will be used in the conference, rather than light from a display, another area, or a shadow. After the object is in place, select Calibrate.

    Color Temperature Value:

    3200 K (tungsten bulb)

    3680 K (warm office fluorescent)

    4160 K (cool office fluorescent)

    4640 K (cool white fluorescent)

    5120 K(neutral daylight)

    5600 K(cool daylight)

    BrightnessAdjust how bright you want the room to appear. Enter a value from -10 to 10.
    Color SaturationDetermines how the camera system transmits hues in certain lighting conditions. For example, a wall looks different in the day than at night. When saturation is zero, the color appears as a shade of gray. Enter a value from -5 to 5.
  3. Optional. Use the Calibrate button to adjust the White Balance with one click. This option is useful when you discover that the color temperature value is not appropriate and you do not want to use Automatic mode to control the white balance.
