| Description: | Special Report Abstract: Four optical-fiber intrusion detection systems (IDSs) and one pulsed near-infrared IDS were operated from October 1992 through July 1993 during conditions of snowfall and rainfall, unfrozen and frozen ground, snow as deep as 80 cm, wind gusts > 20 m/s, and air temperatures ranging from -30°C to 35°C. The optical-fiber IDSs were installed in both buried and fence-mounted configurations. The detection capability of the IDSs was determined with controlled intrusions on a regular basis. Long-term monitoring identified causes of nuisance alarms. |
