Senstar-Stellar has E3i, an interior security microphonic cable sensor. E3i is a detection sensor used to protect the walls and roofs of buildings. It adapts Senstar-Stellar’s strain-sensitive microphonic cable technology used on outdoor perimeter fencing to the specialized requirements of detecting impacts to metal, wood or masonry materials. The sensor cable is mounted to the interior surface and is monitored for signals corresponding to shock, impact and sustained attack when an intruder attempts to cut, smash, crush or saw through the exterior surface.
