Terms
active CPU – The central processing unit of a network security system
operating in the “active” mode, providing centralized control of the
entire system. It may be backed up by a redundant CPU operating in
standby mode, which is capable of taking over as the active CPU at
any instant - upon instruction from the management switch.
admin console – A PC-based graphical user interface (GUI) that facilitates
the interaction between an NSS (network security system) and a
system administrator.
alarm – A programmed association between an event and an action (normally
an automated sequence). For example: motion is detected on a video
camera, and this event triggers a pre-programmed action, such as a
camera preset that is executed automatically by the system. A user
can also control an alarm.
alarm identification number – A decimal number that uniquely identifies an
alarm within the system.
alarm monitor – An external device that receives alarm status information
from the Main CPU, which acts as an interface with an external
alarm system - able to respond to NSS event sources, such as: video
loss detection, motion detection, or digital input state change
detection.
area – An administrator’s selective grouping of several locally numbered
monitors and one or more controllers. A control/communications
center for security will contain one or more areas.
backup CPU – Same as redundant CPU.
camera identification number – Unique record ID assigned by MPU955A
Admin Console as a camera is added, in order to identify one camera
to the system.
camera preset (CPreset) – A predetermined camera position.
camera spot – A camera and its associated preset position. Also referred to
as: spot.
camera surveillance group (CSG) – Several cameras committed to an
identifiable physical space likely to be viewed from one or more
monitors as a preset or tour. This grouping can be a basis for logical
numbering. For example, a CSG could be committed to a concourse,
gift shop, cash register, or loading dock.
camera-to-monitor permissions – Permit a camera to be viewed on certain
monitors, while denying access to others.
camera number – A unique number permanently assigned to the specific
location and port of an individual, installed camera. It is always
linked to a “logical” camera number (
See logical camera number).
