Technical evaluation of rapid deployment and re-deployable intrusion detection systems (RDIDS/RIDS)
The rapid deployment and redeployable intrusion detection systems (RDIDS/RIDS) were extensively tested in 1988 at the NASA Space Center in Cape Kennedy, Florida. A brief history of the testing is given. The pulsed infrared system is integrated with a radio frequency (RF) transmitter operating in the VHF and UHF frequencies, powered by a battery backup photovoltaic energy system. The system was exposed to severe climatic changes throughout the test period. During the test period the system did not generate any false alarms. It was unaffected by high waves, high winds, small birds, leaves, or partial shielding of one sensor by foliage. However, the system did alarm when pelicans flew through the IR beam with outstretched wings perpendicular to the IR beam, covering more than 90% of the beam. A solution to this problem is described. The latest photovoltaic power system developed for use with the RDIDS and the telemetry portion of the RDIDS are outlined.<>
