Abstract

The use of physical security technologies are becoming important to prevent intruders from stealing or vandalizing property, and leaking personal information, as well as to secure personal safety. At many important facilities, fences are installed along the boundary of the premises to prevent any intrusion. Vibration sensors need to be easily fixed to the fences even around intricately shaped premises for monitoring a wide range of areas. We have proposed and implemented a vibration sensor integrated with optical fiber and an optical interference system. To prevent any false or missing alarms, we have also investigated a signal processing system that can be used to judge whether an alarm is triggered by a natural phenomenon, small animals, or human intrusion.
