Alarm Action
The assigned response for the dome camera when an input changes from a normal to an
abnormal state. This is known as an Input Alarm. The response may be for the camera to run a
Preset or have no assigned action.
The dome camera may also send an alarm state to the host controller for processing. This is
known as an Alarm Output. See also Input Alarm and Normal Input State.
Area
Programmed start and end points of the dome's field of view around its axis. Each area is a part of
a circular viewing area that extends around the dome. The areas can be different sizes. Up to 8
areas can be programmed for the dome. Each can have its own title.
Automatic Gain Control (AGC)
Allows for the amplification of the video signal in scenes with minimal ambient light. Typically,
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.
On-Screen Menu
The text overlay menu system used for setting dome features. The utility is accessed using a by
pressing the MENU key on the keyboard controller or by accessing the menu through a DVR.The
utility provides settings for camera functions, zoom, alarm, text display, and password protection.
Flip
Allows the dome to automatically reverse the view from bottom to top, 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.
