3-4.5.1 Multiple connection methods such as dial-up modem, serial (RS-232), multi-
drop (RS-485), and network TCP/IP.
3-4.5.2 Integrated CCTV camera connectivity, allowing CCTV camera information to
be shared with the ACS.
3-4.5.3 Capability for asset tracking within a facility, such as with radio frequency
identification (RFID) tags connected to critical assets.
3-4.5.4
Capability for incorporating duress or panic alarm capability.
3-4.6
Card Readers. The most common form of credential verification is a security
card reader.
3-4.6.1 Types of Card Readers. There are a number of different types of card
readers. Insertion readers require that you insert the card into a slot that is just large
enough to accommodate the card and then remove it. Swipe readers require that you
swipe the card through a long narrow slot that is open at each end. Proximity and
contactless readers require that you hold the card in front of the blank face of the
reader.
3-4.6.2 Insertion and swipe readers, while functional, are older technologies;
however, at this writing the use of the CAC requires use of the insertion type magnetic
stripe reader or a bar code reader. Insertion or swipe readers require the credential to
be inserted into the reader and the card can wear out over time. Once the CAC is
converted to a contactless read capability, use of insertion or swipe readers should be
an unusual design for new projects because of the dated technology. Until the CAC is
converted to contactless read capability, the insertion magnetic stripe reader is
preferred over the bar code reader, which is more easily compromised. Proximity
readers are popular and require the user to pass the card within an adjustable distance
(one to two inches from the reader). While commonly used in commercial non-DoD
applications, testing has demonstrated that it is possible to intercept the unencrypted
(125kHz proximity card) signals. Smart cards are also wireless, contactless credentials
that can be read in close proximity to a smart card reader.
3-4.6.3 Figure 3-7 displays a typical configuration for a single door equipped with a
card reader and electric lock. Refer to the subsections on Doors and Door Locks in
Chapter Nine, General Requirements and Cross-Discipline Requirements for additional
information on door hardware types and interface considerations.
