Alarm Actions The assigned responses for the dome when inputs change from normal to abnormal states.
The dome may run a Preset, Pattern, or have no assigned action for each of the four
dome inputs. The dome may also send alarm states to the host controller for processing.
See also Input and Normal Input State.
Apple Peel Pattern The default pattern of the SpeedDome Ultra VII. This pattern consists of three complete
revolutions starting at the ceiling line and tilting down 30° each revolution.
Areas Programmed start and end points of the dome's field of view around its pan axis. Each
area is a part of a circular viewing area that extends around the dome. The areas can be
different sizes. Up to 16 areas can be programmed for the dome.
Automatic “Flip”
feature Allows the dome to automatically turn 180 degrees when the camera tilts to its lower
limit and stays in that position for a brief delay. When the dome flips (rotates), the
camera starts moving upward as long as the tilt control is kept in the down position. Once
the control is released, the tilt control returns to its normal operational mode. The flip
feature is useful when you need to track someone who walks directly beneath the dome
and continues on the other side. This is also referred to as “proportional flip.”
Automatic Gain
Control (AGC) Allows for the amplification of the video signal in scenes with minimal ambient light.
Many low-light scenes result in picture noise. As gain is increased, the picture noise is
also amplified. When AGC is enabled, the value of the gain setting is based on feedback
from the camera. When AGC is disabled, the camera uses the value set for the manual
gain setting. The trade-off between picture level and noise may be adjusted when AGC is
disabled. See also Open Shutter.
Black and White
Mode See IR Mode.
Configuration
Utility The text overlay menu system used for setting dome features. The utility is accessed
using a keystroke combination. The utility provides settings for camera functions, zoom,
alarms, text display, and password protection.
Direction
Indicators Provides for the display of the camera dome's pointing direction based on the North
setting. This information appears on the top line of the monitor when the setting is
enabled. In addition, the tilt setting appears on the left side of the monitor. By default,
North is set to 0° Pan/Tilt. This setting may be changed using the Set North Position
setting. See also North Position.
Dome Information A Dome Configuration Menu choice that provides essential information about the
SpeedDome Ultra VI camera dome if service is required. When you view this screen, you
can determine the dome type, mnemonic, software version, serial number, and
manufacture date. The information on this screen cannot be modified. See Dome
Statistics.
Dome Statistics A feature that identifies the operating statistics for the dome. The information displayed
represents either runtime in seconds or number of occurrences. See Dome Information.
Dome Status
Information Relates to zoom, focus, and iris settings. You may choose to have this information
displayed on the monitor when any of these settings change. If display of status
information is enabled, it appears in the upper left corner of the monitor.
