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.

INPUT ALARM

A connection point on the dome camera that enables the system to monitor Input Devices. There are

four inputs available for the dome camera.

INPUT DEVICES

External devices that provide information about the condition of system components that connect to

the inputs on the dome camera. Typical input devices include door contacts, motion detectors and

smoke detectors.
