CHAPTER 4
CLOSED CIRCUIT TELEVISION SYSTEMS
4-1
OVERVIEW
4-1.1
The CCTV system is another core subsystem of an overall ESS. It is the
collection of cameras, recorders, switches, keyboards, and monitors that allow viewing
and recording of security events. The CCTV system is normally integrated into the
overall ESS and centrally monitored at the Dispatch Center. Uses of CCTV systems for
security services include several different functions as described below.
4-1.2
Surveillance. CCTV cameras can be used to give a viewer the capability to
be made aware of or view visual events at multiple locations from a centralized remote
viewing area. CCTV camera technology makes visual information available that would
normally only be available through multiple (possibly roving) human resources.
4-1.3
Assessment. When alerted by an alarm notification, CCTV cameras allow
Dispatch Center operators or other viewers to assess the situation and make a
determination as to what type of response may or may not be required. An example
would be an intrusion alarm at a remote facility. Visual assessment and other
confirmation may indicate an unannounced maintenance crew at work. Symptoms of
intrusion would lead to a response.
4-1.4
Deterrence. While more effective against unsophisticated burglars as
opposed to trained covert insurgents, CCTV cameras may deter burglary, vandalism, or
intrusion due to fear of discovery and prosecution.
4-1.5
Evidentiary Archives. Retrieval of archived images may be helpful in
identification or prosecution of trespassers, vandals, or other intruders.
4-1.6
Facial Recognition. Cameras can be used for biometric facial recognition as
discussed in Chapter Three.
4-1.7
Intrusion Detection. CCTV cameras when employed with video content
analysis or motion path analysis software and equipment are increasingly being used as
a means for intrusion detection as discussed in this Chapter under CCTV Camera
Employment for Intrusion Detection.
4-1.7.1
As shown in Figure 4-1, a CCTV system includes cameras (fixed and
pan/tilt/zoom cameras for the interior and exterior of a facility, a digital video recorder,
operator workstation, matrix switchers, and displays.
