 MIL-HDBK-1013/1A
a) "A means is to be provided by which the cause of all
alarms generated at the perimeter security system can be
assessed in near-real-time, physically (i.e., visually)
or remotely through electro-optical (imaging system) or
other electronic devices. To the maximum practical
extent, electro-optical equipment (imaging systems) or
other electronic devices should be utilized, thereby
permitting more effective utilization of the security
and response forces.
b) Real-time visual assessment may be enhanced by
providing an intruder sector indicator at alarm
annunciation locations. This optional feature should
improve the capability to respond quickly with
discriminate application of force, including deadly
force.
c) Imaging systems provide a remote visual image of
activity occurring in an area under surveillance. CCTV,
low-light level television, infrared, and radar are
examples of techniques which may be employed. Such
equipment can be used for area surveillance beyond and
within the perimeter and for assessment of the cause of
alarms and other activities.
d) Facilities used for visual assessment shall be
hardened against small arms fire. Individual cameras,
imaging sensors or scanners do not require hardening."

Elements of a CCTV Assessment System. A typical video system is
composed of one or more cameras, a display monitor, and various switching,
transmission, and recording systems. Coverage of the desired field of view
must be determined through analysis of the camera location, the size and
shape of the area to be surveyed, and appropriate light levels. Control
circuitry enables either manual or automatic selection of specific video
signals for display on television monitors. When an alarm is generated by a
perimeter sensor, the view from any given camera is displayed on the
television so that the operator can assess the cause of the alarm. Guidance
in camera selection and optimization of installation are given in the
references of par. 4.6.1. The following summarizes.
4.6.4.1
Camera Types. Equipment includes cameras with automatic iris
adjustment to accommodate varying illumination levels. Cameras are also
equipped with thermostatically controlled heating elements to compensate for
low temperature environments. A variety of lenses ranging in focal length
are available. This variety permits adapting to varying fence configurations
and blind zone lengths. Supports for the cameras include a tilting
cantilevered mast that permits the support to be installed inside the
boundary fence while the camera is suspended over the fence, viewing the
clear zone. Also included
