Southwest Microwave offers several high-performance, stand-alone active and passive infrared sensors specifically designed for outdoor intrusion detection applications.
Active infrared technology employs a two-column sensor for detection of intruders. The transmitter unit emits invisible active infrared beams. The receiver unit receives and analyses the beams and detects intruders passing between the two columns.
With passive infrared technology, intrusions are detected by sensing temperature (heat radiation) contrast between an intruder moving through the detection pattern and the background environment. Rugged construction, integrated heaters and self-adapting technology assure the reliable operation and constant detection capacity of Southwest Microwave’s infrared devices under changing environmental conditions or temperature extremes.
Active Infrared Intrusion Sensors
Model 460B Active Infrared Intrusion Sensor
With six high power infrared transmission beams, the 460B creates an undetectable protection zone up to 100 m (328 ft).
Model 455B Active Infrared Intrusion Sensor
Quad-beam sensor with 50 m (165 ft) range designed for gate protection or walltop applications.
Passive Infrared Intrusion Sensors
Model 420 Passive Infrared Intrusion Sensor
Digital Signal Processing, Adaptive Threshold Decoding and Signal Shape Analysis ensure reliability in varying conditions.
