<p>An intrusion detection and warning system and method capable of pinpointing location of a breaking in attempt wherein the system relies on vibration sensors positioned along a sensor line that is installable on a fence sector, a signal processing unit located on one end of the sensors line and said sector resistor is placed at a second, other end of the sensor line and connected to it. Wherein the system is characterized by an array of parallel formation resistors that are each connected to a vibration sensor. Wherein one end of each of the resistor is connected to the sensors line, the other end is connected to a voltage measurements line. The the system defines at said voltage measurements line, a point in which a voltage can be sampled, and wherein in addition, the system includes a sampler that enables sampling the voltage at said define point.</p> |
