Glossary
Alarm Actions
The assigned responses of the dome camera when there is input status change.
The dome may call Presets for each of the eight inputs. The dome reports the
alarm states to the Keyboard controller for processing.
Area title
It is the name of the horizontal sector from a certain start point to end point of
the selected dome. Up to 24 areas can be programmed for the dome.
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.
DiagonalScan
Move from start point to end point including tilt and zoom simultaneously and
linearly.
Digital Slow Shutter (DSS)
DSS enhances video quality in extreme low-light situations. When the Low 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).
Flip/ Digital Flip
It allows the dome to turn 180 degrees when the camera tilts to its lower limit.
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.
Home Position
The default position to which the dome camera returns after an assigned period
of inactivity passes. The default position may be a Preset, Tour, Pattern, or No
Action.
