Abstract
A system for monitoring and distinguishing occurrences along a perimeter bounded by at least one piezoelectric cable that completely defines the perimeter. The monitoring system utilizes at least one piezoelectric cable that generates electrical signals in response to mechanical stress events. The electrical signals from each piezoelectric cable are analyzed by a processing system to determine event classification and location. The monitoring system alerts users and connects to an existing security system to notify third-parties. The monitoring system includes functionality to communicate with a calibration unit and calibrate itself. The monitoring system also includes functionality to interface with a pet containment system.
