G-4 SpeedDome Ultra VI Operator's Manual
Preset
Programmed video scene, based on a specific pan, tilt, zoom, and focus settings. Up to 96
presets may be programmed for the dome. For domes running in a Manchester network, only
64 presets may be programmed. See also “Virtual Views”
Privacy Zones
Masked areas of the camera dome's viewing area. These masks prevent operators of the
surveillance system from viewing these designated zones. Each Privacy Zone has four sides,
and the zones may overlap to form irregular shapes. The Privacy Zones move in relation to
the dome pan/tilt position. In addition, the apparent size of the Privacy Zone adjusts
automatically as the lens zooms in or out. Up to eight Privacy Zones may be established for a
camera dome.
Shutter Limit
Setting used to define the maximum exposure time for the Open Shutter setting. The values
for the setting range from 1/2 to 1/60. The default setting is 1/4.
“Virtual Views”
Similar to Preset. However, virtual views store the pan, tilt, zoom, focus, and iris settings
within the controller, not the dome. Virtual Views cannot be used for the Home Position or
Alarm Actions.
White balance
Adjustments in the color hue (red and blue) gains for a camera so that true white appears
white in the image. It is normally compensated for by the automatic gain control. In some
lighting conditions, you may need to manually adjust the red and blue settings for optimal
viewing. When Automatic White Balance is enabled, the camera measures the image and
automatically adjusts the red and blue settings to balance white. When Automatic White
Balance is disabled, the camera uses the values set for the red and blue settings to balance
white.
Wide Dynamic Range
A feature of the camera that allows a scene with both bright and low light areas to be viewed
simultaneously.
Zoom
To adjust the magnification of the camera lens to make an object appear closer (larger) or
farther away (smaller). See also Zoom stop factors.
Zoom stop factors
Defines how the zoom function is partitioned. The first zoom stop setting may be 23X or
35X. The default first zoom stop setting is 23X. The maximum zoom stop setting may be 46,
69, 92, 115, 138, 161, and 184X. The default maximum zoom stop setting is 92X.
