Abstract
A system for monitoring and distinguishing occurrences along a perimeter bounded by a plurality of piezoelectric cables. The monitoring system utilizes a plurality of piezoelectric cables that generate electrical signals in response to mechanical stress events. The electrical signals from each piezoelectric cable are analyzed by a base unit 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.
