<p>The invention relates to a sensorized or intelligent security fence or grille. According to the invention, the interior of the electrically-conductive plastic or metallic fence, grille or structure is sensorized by means of an electric conducting wire. In this way, a variation in the state of the circuit (normally open or normally closed) is detected by the alarm centre to which it is connected. The inventive structure can be mounted in the form of fences delimiting properties, grilles in hollow walls, sensorized decorative elements between double glazing panels or in any other form, since the claim related to the sensor unit regardless of the form or size obtained through the combination of individual sensors. As can be seen, the aforementioned type of sensor is not prone to failure given that it does not contain any active elements that could be altered owing to variations in temperature. Moreover, the inviolability of said sensor is ensured without being detected since variations in the form of the structure are detected regardless of whether they occur slowly or suddenly, using plastic, gaseous or metallic materials, and regardless of the angle of intrusion.</p> |
