Magnum Security offers several high-performance, stand-alone active and passive infrared and microwave sensors specifically designed for outdoor intrusion detection applications.
Active infrared and microwave technology employs a two-column sensor for detection of intruders. The transmitter unit emits invisible active infrared or microwave beams. The receiver unit receives and analyses the beams and detects intruders passing between the two columns.
With passive infrared and microwave technology, intrusions are detected by sensing temperature (heat radiation) contrast between an intruder moving through the detection pattern and the background environment.
