central processing unit (CPU) – The part of a network security system
(NSS) that controls the functioning of the entire system, which it
also enables. Operates on either active or standby status. If active, it
is the Main CPU; if in standby, it is the redundant (or backup) CPU.
compensation – Hardware capability to boosting signal strength in a response
to the length of the cable length installed: short, medium, or long.
controller – A user tool for selecting and aiming a surveillance camera. Can
be either a GUI screen image, or a physical device with a set of
alphanumeric keys and a joystick.
control port (CPort) – Input port on the video input board.
controller-to-alarm permissions – Permit a controller to access certain
alarms, while denying access to others.
controller-to-camera control permissions – Permit a controller to control a
certain camera, while denying access to others.
controller-to-camera view permissions – Permit a controller to view the
output of a certain camera, while denying access to others.
controller-to-group sequence permissions – Permit a controller to conduct a
certain group tour, while denying access to others.
controller-to-monitor permissions – Permit a controller to access a certain
monitor, while denying access to others.
CPU management switch – Also called "management switch," or "Mgmt
Sw." See management switch.
Ethernet address (EA) – A unique 48-bit address hardwired into the
electronics of the Ethernet board of the network device. The address
is written in hexadecimal form. Example: 3C.80.7F.13.83.2A
(Also known as MAC address.) This is not the same as an Internet
Protocol (IP) address.
Ethernet controller – A system controller that communicates via an Ethernet
physical-layer interface.
event generator – A device that indicates the occurrence of several external
events to the Main CPU, via a single physical interface. The Main
CPU responds to event indications as instructions to execute pre-
programmed actions, such as triggering an alarm, closing outputs, or
running tours. External alarm and card-access systems are examples
of event generators.
group preset – A collection of monitor-camera pairings, whereby in a single
shot, a group of monitors will display video output from cameras at
specific preset positions.
group sequence – An automated sequence of group preset steps.
GUI controller – A system that provides a user with a PC-based graphical
user interface (GUI) controller emulating specific keyboard
controllers.
