CHAPTER 8
ESS SUBSYSTEM INTEGRATION
8-1
OVERVIEW
8-1.1
Since the different subsystems of a facility's total ESS are drawn on a number
of different technologies (i.e. camera technology, biometric technology, microwave
intrusion technology, and information transfer technology), the manufacturers of
subsystems tend to be uniquely different. As a result, system integration or making the
subsystems and components "talk to each other" reliably and consistently is a major
portion of an ESS design. The purpose of this chapter is to briefly consider some of the
system integration issues associated with an ESS.
8-2
COMMUNICATION FROM THE IDS TO THE ACS
8-2.1
As covered in Chapter Two, "Electronic Security System (ESS) Overview," for
a simple system, the IDS may already be an integral part of the ACS. In these
intermediate systems (depicted in Figure 2-7), basic intrusion detection devices are
brought into a combined ACS/IDS system as digital inputs on local security panels. All
that is required is to allocate digital input points in the closest security panels and
program the ACS to provide an alarm on event.
COMMUNICATION FROM THE IDS1 TO THE CCTV SYSTEM
8-3
8-3.1
Once an intrusion is detected (i.e. door forced open or perimeter fence or
microwave intercept), it is generally the practice to make sure the event is being viewed
and recorded. Interface of the IDS to the CCTV system can occur through several
different means: hardwired conductors, serial communications, and networked
connections as discussed below. Activation of an intrusion detection alarm results in an
audible alarm that gets the operators attention.
8-3.2
Hardwired Conductors. Older technology; still effective for simple
installations. In this case, copper conductor wiring is taken as digital outputs from the
IDS or combined ACS/IDS and connected as inputs to the CCTV system to initiate
camera recording and if required panning to a pre-set location. In the most basic
approach, this design requires a pair of wires for each alarm notification output signal.
8-3.3
In theory, this is the same principle of operation as the hardwired method with an
improvement in that a single RS232 conductor pair can handle several camera signals.
It is most easily done when the CCTV and IDS (or combined ACS/IDS) are made by the
same vendor, but can be done with different vendors, but requires writing or availability
