Recently, the vibration intrusion detector, independently developed by special product business division in Yangtze Optical Fibre and Cable Joint Stock Limited Company (stock code: 6869.HK, hereinafter referred to as “YOFC”), has successfully passed the type inspection and incoming inspection carried out by National Quality Supervision and Inspection Center of Security Alarm System Product (Beijing) and obtained the highest certification about national security products.
Optical fibre perimeter monitoring system is the innovative application of optical fibre sensing technology in perimeter security area, which effectively solves the problems of common security equipment such as vulnerable to environment interference, hard maintenance and short service life, improves the recognition accuracy of intrusion behaviors by perimeter monitoring system, provides more information to let users study and judge the intrusion event, and also improves the satisfaction of user experience. Meanwhile, it also reduces the complexity of engineering construction power supply and the workload in later usage maintenance; therefore it has very strong application value and popularizing prospect. YOFC vibration intrusion detector (optical fibre perimeter intrusion detector) and matched monitoring system are the alarm system using optical fibre as the sensor to achieve distributed perimeter security monitoring, which are mainly used in places featuring inflammability and explosibility, large electromagnetic interference, high safety demand, high detection concealment, long distance and large range. The uniquely designed sensing optical cable unit is very sensitive to movement, pressure and vibration. It can detect climbing and cutting when laid along the fence and enclosing wall, and it also can detect those intrusion behaviors such as treading and excavation when laid under the soil, gravels and turf. The system will alarm once crossing, passing through, climbing, violent invasion and other behaviors occur.
The optical fibre perimeter intrusion detection system of YOFC has been widely used in power sector, national defense, public utility, transportation, petrochemical engineering and other sectors and won unanimous praise from customers. Passing this inspection successfully not only shows the highly recognition towards this vibration intrusion detector (optical fibre perimeter intrusion detector), but also provides confidence and assurance to customers during selection of YOFC optical fibre perimeter security products.
