Alpha Sensor Cable Technology - Micro phonic Audio Verification System

AUDIO VERIFICATION is the unique feature of our perimeter security system . The ONLY perimeter security system in the world that has this feature. This is achieved through the use of the ALPHA Cable, specifically manufactured for the perimeter security market. Its patented magnetic construction combined with the very latest techniques in sensor design have resulted in it being the benchmark for the industry.

The latest version of DEFENSOR, provides the capability to effectively combine the advantages of its proven Alpha sensor cable technology with the physical delay factor and vibration transmission characteristics of the perimeter fence. Defensor, in conjunction with the physical barrier provided by the perimeter fence, forms the first line against attempted intrusions. It is designed for applications on manned or unmanned sites, whether as a stand-alone single zone system or as part of a comprehensive multiple zone installation.
