Glossary
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.
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.
Configuration Utility
The text overlay menu system that a provides a means to setting features for the dome. The
utility is accessed using a keystroke combination. The utility provides settings for camera
functions, pan, tilt, zoom, focus, alarms, text display, and password protection.
