Perimeter Intrusion Detection
We offer several high-performance, stand-alone active and passive infrared sensors specifically designed for outdoor intrusion detection applications for early warning.
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.
