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.
Quick Set Menu
A special menu that provides access to commonly used features and functions when
used with compatible controllers. This allows for changing or activating features
without starting the dome configuration menu.
Random Scan
An automated scan that pans randomly between the left and right scan limits, starting at
any point between the scan limits. See Smooth Scan and Stepped Scan.
Scan
Automated surveillance between predefined scan limits. Three types of scans are
available: smooth scan, stepped scan, and random scan. See Smooth Scan, Stepped
Scan, and Random Scan.
Scan Limits
Two points around the dome’s pan axis, which define a surveillance area.
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 for NTSC, and 2/3 to 1/50 for PAL. The
default setting is 1/4 for NTSC and 1/3 for PAL.
Smooth Scan
An automated scan that slowly pans between the left and right scan limits, starting at
the left scan limit. When the right scan limit is reached, the scan reverses. See Stepped
Scan and Random Scan.
Stepped Scan
An automated scan that pans slowly pausing momentarily every 10° between the left
and right scan limits. Once the right scan limit is reached, the scan reverses. See
Smooth Scan and Random Scan.
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.
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 22X
or 33X. The default first zoom stop setting is 33X. The maximum zoom stop setting
may be 44, 66, 88, 110, 132, 154, 176, 198, 220, or 242X. The default maximum zoom
stop setting is 88X.
