AquaMesh Underwater Intrusion Detection

  • AquaMesh

Aquamesh is a rigid steel grating supporting an interlaced fibre-optic sensor cable which is fully encased in solid resin. This combination of a tough physical barrier with intrusion detection provides an extremely effective alarm generation system. Aquamesh can be fabricated in sizes and shapes tailored to your exact requirements. Remsdaq custom engineering services are available for full project support from design to implementation. The principle of operation is based on fibre-optic continuity sensing; only when a fibre-optic cable is severed is an alarm produced and accordingly the system has a very high level of reliability.

Approved and used by the CPNI (UK Centre for the Protection of National Infrastructure) sites, Aquamesh is designed for semi or fully-submerged water course security applications.

OptiMesh Solution

Approved and used by the CPNI (UK Centre for the Protection of National Infrastructure) sites, OptiMesh operates on the same principle as AquaMesh but forms a physically flexible weatherproof, tamper proof fibre optic detection mesh suitable for but not limited to, the following applications:

  • Covert installation of OptiMesh mounted within a wall cavity or covered with appropriate building fabric
  • Outdoor applications for OptiMesh, include attachment to moving flexible structures
  • Dock and Jetty security for both commercial and military scenarios
  • Delivers a very high MTBF performance

The Sabre II Processor module monitors both AquaMesh and OptiMesh applications, available in circuit board form, or supplied in an enclosure with optional power supply/charger and rechargeable battery.  Especially designed for easy integration with third party monitoring products such as Command and Control (PSIM) Video Management System or Access Control Alarm Management systems.
