This is very similar to a tripwire in concept. There would be a second identical device a few 100 feet away with a mirror. This device produces a beam that travels to the device with the mirror, and the mirror reflects the beam back at the device. Anything crossing the beam interrupts the beam and alerts of any intrusion.
