High security locations will soon be able to improve their intruder protection capability following the development of a unique system that has been created as part of a project being run by the European Commission.
Fenceguard, as the system is called, combines an Integrated Machine Vision (IMV) system with fibre optic cabling that can be installed as part of a fence or laid underground.
In operation, light generated from a laser diode passes through the fibre optic cable. At the end of the cable, a 2000 element CCD detects the pattern of light reaching it. When the cable is touched, or triggered by movement, the image on the CCD changes. The machine vision system then performs a frequency analysis on the image and distinguishes between what constitutes a false alarm and an intruder.
The system was developed as part of a European Commission project, EUTIST-IMV, which is aimed at promoting the adoption of IMV technology across a wide range of industries. It was trialled successfully at a major European explosives factory as part of a programme covering Hungary and Finland and will be shown to the public for the first time at next month’s Automaatio exhibition in Helsinki, Finland between September 9-11.
Fenceguard is one of 23 pilot projects being run by the European Commission to promote the uptake of Machine Vision. It was developed by Multitec and CCD Photonics of Finland and Electro-Technic of Hungary.
