DEFINITION OF TERMS
mechanisms that momentarily permit access (for example, by unlocking doors or gates)
after verifying entry credentials (i.e. using a card reader). Other DoD documents may
refer to the ACS as an Automated Access Control System or an Electronic Entry Control
system. The ACS may also be referred to as an Automated Access Control System
(AACS), Electronic Access Control System, and Electronic Entry Control.
Arms, Ammunition, and Explosives (AA&E).
Balanced Magnetic Switch (BMS). A door position switch using a switch held in a
balanced or center position by interacting magnetic fields when not in an alarm
condition.
Base Level Information Infrastructure: That information technology (IT) infrastructure
which exists on DoD proprietary or leased property.
Base Operations Center (BOC). An operations center for a DoD base, that has
equipment and personnel for operational responses. Typically, the BOC is the receiving
point for emergency alarms from fire alarm, ESS and 911 calls. This location is typically
staffed by trained staff twenty-hour hours a day.. The BOC may have a law enforcement
desk of handling domestic dispute or interface with local and federal authorities.. The
BOC is typically the will house the Dispatch Center, which is the centralized location for
receiving and assessing ESS alarms.
Cathode Ray Tube (CRT). A technology used in television and computer display
screens. A CRT works by moving an electron beam back and forth across the back of
the screen. Each time the beam makes a pass across the screen, it lights up phosphor
dots on the inside of the glass tube, thereby illuminating the active portions of the
screen. By drawing many such lines from the top to the bottom of the screen, it creates
an entire screenful of images.
Charge-coupled device (CCD). A semiconductor technology used to build light-
sensitive electronic devices such as cameras and image scanners. Such devices may
detect either color or black and white.
Closed Circuit Television (CCTV) System. The system that allows video assessment
of alarm conditions via remote monitoring and recording of video events.
Common Access Card (CAC). As envisioned, the CAC is the standard ID card for DoD
personnel. The full implementation of the CAC for access control and personnel
information may take three to five years. In addition to providing identification
information, it is planned to be the principal card for physical access to buildings and
other controlled spaces. It contains limited information related to work function, benefits,
and privileges, but does not include medical or personnel records. In addition to
allowing building access, it also allows computer logon and enables email encryption
and electronic document signatures. The credit card sized CAC uses five different
