ZoneSentry™ – Perimeter Intrusion Detection System

ZoneSentry is a zone-based perimeter intrusion detection system, which utilises fiber optic sensing technology. The solution provides real time monitoring of vibrations on the perimeter and key assets within, enabling rapid detection and communication of intrusion events.

The system is based on fiber optic vibration monitoring technology. By attaching the fiber optic sensing cable to the external perimeter or on key assets you can detect the vibrations associated with intrusion events and rapidly detect and take action to prevent damage or theft.

The system has a zone based approach and can have up to 8 zones per unit. Each zone can be 1km in length (with up to a 10km lead-in, insensitive length). Each zone is effectively a fiber optic loop with a Zone Activation Unit at the start, which activates the zone – making it sensitive to vibration. The zones can be configured individually and so different sensitivities can be applied across the installation.

Key Applications

  • Power, utilities and substations
  • Renewable energy
  • Telecoms
  • Well heads, block valves and pumping stations

System Advantages

  • Simple and low cost of installation
  • Cable immune to Radio Frequency or Electro Magnetic Interference
  • Up to 8km of perimeter monitoring per unit
  • Location of event to within a user defined zone
  • Custom configuration of zone sensitivity – minimise nuisance alarms
  • Flexible and versatile
  • Simple integration with existing software

The Technology Principle

The ZoneSentry system is based on the principle of the Sagnac interferometer. Fiber-based Sagnac loop sensors, as opposed to all other types of common interferometers, have the unique advantage of providing the same physical path for the two counter-propagating light waves that create the optical interference, hence eliminating signal fading problems due to path instabilities caused by environmental disturbances.

This technology has a number of benefits including:

  • High stability
  • Self-balancing characteristics
  • Compact structure
  • Simplicity – single zone activation unit and otherwise standard fiber optic cable.
System Integration – The MaxView Advantage

The ZoneSentry can be integrated as a standalone system or with Bandweaver’s MaxView integration software and so has very good versatility with regard to interfacing with different security VMS and PSIM packages.

Below is an example of a 4 zone integration with integration for CCTV for each of the respective zones through a DVR system:
