8 Glossary of CCTV Terms

Address

Each AutoDome has a numerical address in the control system in which it is located. This

allows the appropriate dome to be operated. The address may be set locally using the Bilinx

Configuration Tool for Imaging Devices (CTFID) or remotely using the Fast Address function

(see Fast Address).

Advanced Alarm Control (AAC)

AutoDome’s flexible and sophisticated alarm management subsystem that allows “rules” to be

created that define which input(s) activate one or more outputs (see Alarm Rule). In its most

basic form, a rule could define which input(s) should activate which output(s). In a more

complex form, a rule can be programmed to take a specific keyboard command (pre-existing

or not) and perform a dome function, or any combination of the above.

Advanced Diagnostics

Bosch’s combination of built-in On Screen Displays (OSD) and status LEDs that are used to

check critical camera parameters such as internal temperature, input voltage levels, and

network connectivity. This allows a technician to quickly determine the source of problems

and ensure that the dome is functioning within correct operating limits.

Aperture

The size of the opening in the iris, which controls the amount of light that reaches the CCD

Sensor. The larger the F-Stop numbers, the less light reaches the sensor.

AutoBlack

A technique of boosting the video signal level to produce a full amplitude video signal even

when the scene contrast is less than full range (glare, fog, mist, etc.). The darkest part of the

signal is set to black and the lightest part to white, thus increasing the contrast.

AutoDome

Fully integrated, high speed, pan/tilt/zoom camera built into a protective dome housing

allowing full and continuous 360° coverage of the scene.

Auto Focus

The lens continuously adjusts to the correct focus automatically for the sharpest picture.

AutoIris

The lens iris opening is automatically adjusted to allow the correct illumination of the camera

sensor.

Automatic Gain Control (AGC)

The electronics that regulate the gain or amplification of the video signal.

AutoPan

The camera pans continuously between right and left limit settings.

AutoPivot

As the camera tilts through the vertical position, the camera is rotated to maintain the correct

orientation of the image.

AutoPlayback

This function records the sequence of movements of the AutoDome PTZ for later playback

allowing a set pattern to be repeated automatically. This function is often called Guard Tour.
