Long-term Perimeter Protection System Monitoring Using State of a Polarization Analyzer

Abstract

The paper proposes the deployment of a perimeterand data protection system with long-term data storage in anInfluxDB time-series database enhanced by a graphical interfacebased on a Grafana dashboard. The perimeter is protected usinga fiber optic cable, and the transmitted light is analyzed by a stateof polarization analyzer detecting mechanical vibrations. Usinga simple spectrum comparison method and a threshold, it candetect a perimeter breach and generate an alert.
