Notes: The system has three detectors (shown at the front, left-to-right): magnetic, seismic, and infrared. In the back row are (left-to-right): a hand-held monitor, a laptop computer for programming and display, and a signal repeater.
Modern sensor systems are continually becoming smaller and more sophisticated.
