In this video we demonstrate how the IRONCLAD and Micalert Perimeter intrusion detection system PIDS systems filter long-wave vibrations similar to wind while still triggering sharp vibrations (impact) similar for climbing, cutting or lifting. One zone is triggering security lights and the other a preset for a camera.
Those fence security systems are great replacement for IR beams.

Works the same on chain link, welded mesh or any metallic fence.
