Abstract (en)
[origin: EP1341137A1] A security system particularly for property surveillance, to be associated with a guard structure (1) that may be subjected to bending forces. The system is provided with at least one sensor (6) for detecting deflections of the structure resulting from the forces. The sensor (6) comprises a substantially plate-shaped piezoelectric transducer (10) such as to convert mechanical stresses into electrical signals and a container (40) for the transducer (10), which container (40) can be fixed to the guard structure. The container (40) is such as to deform resiliently as a result of the bending forces and to transmit the deflections of the structure to the transducer (10) so that they give rise to corresponding electrical detection signals. <IMAGE>
