Cold Regions Performance of Optical-Fiber and Pulsed Near-Infrared Intrusion Detection Systems
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 deg C to 350C. 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.
