Detection & Notification of Intrusion or Perimeter Breach

Perhaps you've seen the reports of absent or failed perimeter detection systems.

CNN reported on this December 13, 2015 perimeter fence breach at JFK Airport by Rene Marsh and Sarah Jorgensen:

Implementation of a complete, functional perimeter security detection and video observation system is critical.  If the proper technology is applied and maintained, breaches will be detected immediately.

Shock detection technology is based on vibrations analysis.

The Protech G-Fence system collects information of intrusion by climbing, cutting or tearing of the support. In order to detect intrusion attempt, a detector cable is installed on the support (fence or inner wall) to detect every vibration due to cutting climbing or tearing. The advantage of this kind of technology compared to a detection with microphonic cable, is the simplification of installation and maintenance process.
