4.3 Glossary
Alarm Actions
The assigned responses for the network dome camera 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.
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 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.
