 6.1.2 Alarm Response Direction. One of the most important functions of the
alarm station monitor is to direct appropriate response to an alarm
situation. CCTV eliminates the need to rely upon verbal reports from fixed
manned observation posts. It enables alarm station personnel to tailor the
response to the viewed alarm cause. Procedures should require that all
actual intrusion alarms and all alarms should be responded to, especially
those for which no cause can be immediately determined. An example of a
tailored response would be that for an alarm zone which will not reset, it
may be appropriate to send maintenance personnel with the responding
security forces. In short, CCTV, when used with prudent operational
procedures, can increase security system effectiveness in responding to an
intrusion alarm.
6.1.3 Directed Surveillance. CCTV may be used for surveillance of
protected areas or spaces as directed by Navy regulations or by local
directives or procedures. Pan and tilt camera mounting platforms are used
normally because they enable more cost-effective coverage of a large area
than with multiple fixed cameras. Caution in use should be considered;
attempts to use surveillance cameras for alarm assessment may result,
causing misassessment or no assessment of an alarm event. Personal privacy
areas and areas where classified materials are used are usually off-limit
areas for surveillance by remote devices. It should also be remembered that
surveillance is not a substitute for IDS coverage. Human factors studies
have verified that alarm station personnel can only focus their attention on
a surveillance monitor for a short period of time before becoming
inattentive. Normally, remote surveillance is required of several areas
which also results in inattention because of distraction by activity on
other monitors. In summary, CCTV surveillance can be an effective
supplement to the security system but should be used prudently lest it
become a perceived panacea when only the illusion of effective security is
achieved.
6.1.4 Event Recording. Recording is a valuable tool to enable
reconstruction of alarm events, analysis of nuisance/false alarms by
maintenance personnel, and for reviewing by alarm monitor personnel for
assessment in the case of multiple alarm scenarios. CCTV systems accomplish
these objectives through the use of video tape recorders (VTRs) to record
video data as required. Video tape recordings have been accepted as
evidence in both civil and federal court and in courts martial provided that
a custodial "chain" for the recording can be documented (as for any other
key evidence). Further discussion on VTR types and application is contained
in the paragraph entitled "Options for Enhanced Capabilities." Event
recording can assure coverage of alarm events when alarm monitor personnel
are not present and can assist command personnel in reviewing significant
events. While this capability can be expensive relative to other assessment
subsystem components, it has often proved cost-effective in many Navy
applications when compared with human-intensive solutions.
6.1.5 Access Monitoring. CCTV is sometimes used for remote monitoring of
access (entry/exit) control points. This application is suitable for
general monitoring of access flow and central activity monitoring. However,
it has proven unreliable in assuring positive identification of individuals,
such as picture badge-face comparison, especially under high throughput
requirement
