Preliminary Evaluation of a Perimeter Intrusion Detection and Assessment System

The design and implementation of a Perimeter Intrusion Detection and Assessment System (PIDAS) for a large material storage site was described in a report presented at the 1977 INMM Conference.* Several new design concepts were incorporated into this system which were intended to reduce the number of nuisance alarms requiring on-site investigation by a security force. In the 10 months since installation and initial debugging were completed, evaluation of PI DAS has continued. Based on the insights gained through monitoring operational performance, correcting equipment deficiencies, and transferring responsibility to the using organization, an initial assessment of the design concepts has been completed.
