Glossary
A
alarm contact A sensor which, when activated, signals a change from normal system operation.
Alarm contacts are associated with cameras or camera salvos in programmable
alarm tables.
alarm table A table written in computer memory which associates alarm contacts (sensors) with
cameras or and/or camera salvos. The table includes information about camera
dwell times, preset numbers, auxiliary status, alarm title numbers, camera linking
status, and alarm scene locations.
arming Arming is the process by which a video monitor or monitor block is associated with a
specific alarm contact, and is assigned an appropriate monitor arming code.
arming code A monitor’s arming code defines how an alarm scene will be displayed, queued, and
cleared on the monitor. Display methods include Single, Dual, and Block. Queuing
methods include Hold and Sequence. Clearance methods include Instant, Auto, and
Manual.
auto clearance Automatically clears the alarm camera scene 20 seconds after the associated alarm
contact is reset at its source location. If the alarm is set again within the 20 second
interval, it does not clear (for example, a door equipped with an alarm sensor is
opened, closed, and opened again within 20 seconds).
auxiliary A relay switch which controls the “on” or “off” state of devices such as door locks,
gates, and lights.
B
baud rate A rate of transmission measured by the number of bits per second sent over a
computer-controlled communications line.
bay An enclosure containing the electronics modules and bus circuitry necessary to
perform switching system functions. The AD168 system is available in both single
and dual bay configurations.
block A contiguous group of video monitors. Contiguous is defined as an uninterrupted
integer sequence. For example, monitors 1,2,3,4, and 5 are contiguous. Monitors 1,
3, 5, and 7 are not.
block display Multiple alarm camera scenes are displayed on the block of monitors with which they
are associated. The lowest number of the block displays the first alarm scene, the
second lowest numbered monitor of the block displays the second alarm scene, and
so on.
C
camera lock camera lock is a programmable function which prevents a user or keyboard from
controlling camera pan/tilt and lens adjustments, preset positioning, and auxiliary
actions.
connect next “Connect Next” refers to a set of linking options used with tours, salvos and alarm
contact tables, which defines how each salvo, tour, or alarm contact table entry is
connected to the next entry.
