SpeedDome Ultra VII Glossary
Setting used to improve the quality of video obtained in extreme low-light
situations. When the Open Shutter setting is enabled, low-light information is
collected over multiple fields based on the Shutter Limit setting. As a result,
video may appear blurred or choppy in extreme low-light situations. This setting
does not effect camera operation in normal lighting situations. See also
Automatic Gain Control (AGC).
Prevents unauthorized users from starting the Configuration Utility. The
password may be from 1 to 8 characters long.
A series of pan, tilt, zoom and focus movements from a single programmable
dome. Up to 3 patterns may be programmed for the dome.
Button found on some controllers that initiates the Apple Peel pattern.
See Apple Peel Pattern.
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".
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.
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.
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.
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.
To adjust the magnification of the camera lens to make an object appear closer
(larger) or farther away (smaller). See also 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.
