 MIL-HDBK-1013/1A
4.5.4
Exterior IDS Options for Detection Along Site Perimeter Fences
4.5.4.1
Most Commonly Deployed Sensors. Table 7 lists a number of exterior
sensors used along fence perimeters. There are three classes: fence-mounted,
free-standing, and buried sensors. On-site visits to Navy, Air Force, and
Army facilities disclosed that although all of the sensors shown in Table 7
are utilized by DoD, the following are most common:
o
Fence-Mounted: Strain-sensitive cable on the fence fabric in
combination with a "Y" taut wire on the fence outriggers.
o
In Clear Zone Between Fences: Ported Coaxial Cable Sensor
(PCCS) or, alternatively, a microwave fence sensor (MFS).
o
Threat Assessment: Tower guards or CCTV for threat assessment
after one or more of the above sensors have detected the
intrusion.
