Abstract :
The performance of fence-mounted perimeter intrusion detection systems (PIDSs) is examined. Performance specifications, the current performance of operational systems, fence and sensor types, and other factors affecting sensor performance are discussed, along with the implications of fence sensitivity variations and the measurement of these variations. The on-site optimization method (OSOM) is then introduced. Fence impact testers are a vital part of the OSOM. The OSOM addresses problems caused by different fence types, variations in sensitivity from zone to zone, and variability along each zone. The OSOM was developed for the optimization of a microphonic cable PIDS with digital signal processing. Adjusting the PIDS processing parameters to give a guaranteed level of detection, advantages over analog systems, and a comparison with off-site tuning are discussed
