In the past there have been designs and technologies which have attempted to emulate the detection capability of the Guardwire cable sensor. The superior design of Guardwire can be demonstrated when viewed more closely and compared with these other technologies. Firstly, the two conductor wires of the Guardwire cable sensor together with the detection electronics are in fact two pseudo-detection systems.
This innovative solution is called Dual Channel Signal Processing (DCSP) and means that the two most common types of attack to medium and low security walls, and roofs - impact and sustained - can be independently adjusted without compromising each other. This is a key limitation of other systems, where adjustment of one attack detracts from the other, as they occur at different frequency ranges on the same sensing circuit.
