There are several different systems on the market for the protection of fences, usually “microphonic” systems, which detect movements in the structure to which they are fixed. All of these systems have different limitations.
The single point type uses piezo-electric or inertial transducers distributed along a cable, that carries the information to a common signal processor: along the way these signals are mixed with all the signals created by the other transducers as well as the noise acquired from the whole structure.
The distributed type has a single transducer, which is the cable itself, using the piezo-electric or capacitive or tribo-electric effects – which requires the friction caused by the inner conductor rubbing against the outer sheath: installation is therefore difficult, as it is very likely to damage the cable causing a poor performance.
On the other hand SIOUX uses innovative mems transducers which, besides overcoming those limitations, allow very precise measurements, which are repeatable and stable even in different environmental conditions, of the disturbance that occurs on any direction.
While the other transducers can only detect changes in state of rest, each SIOUX sensor is capable of measuring even its static position in space.
