<p>The invention relates to an integrated system of perimeter protection and data transmission using optic fibres,comprising tracts (2) of fencing realised with tensed wires (3) distributed on levels which are substantially parallel among each other, adjacent levels being distanced less that what is necessary for the passage of a person, the said system comprising, for each tract (2) of fencing, a single wire (3), with at its inside at least a first optic fibre (4), rigidly fixed only at its ends (3a, 3b), so as to be tensed over all of the said tract (2) of fencing with a single operation, and constrained to a single sensor group (6), for the perceiving of any pulling whatsoever on the said single wire (6). <IMAGE></p> |
