Sabre II Perimeter Intrusion Detection

  • Sabre II PIDS

Sabre II is a fibre-optic based Perimeter Intrusion Detection System (PIDS) and can protect many forms of physical barrier including fences, gates, walls, roofing and cover buried applications. Sabre II can sense and alarm for attempts to climb, crawl or sever the fencing. The technology uses a continuously monitored and intrinsically safe, fibre-optic sensor cable which is sensitive to vibration, flexing and compression.

Sabre II is designed for use with Remsdaq’s proprietary fence-mounted (SabreFonic) and buried (SabreLine) sensor cables. Disturbance of the fibre-optic sensor cable is detected in the Sabre II processor and analysed using a microcontroller with digital signal processor (DSP). When a disturbance exceeds pre-set conditions, an alarm will be generated. Automatic environmental compensation algorithms ensure the highest probability of detection whilst ensuring a minimum of nuisance alarms from natural causes.

Sabre II is factory set to enable rapid installation and commissioning.

Application specific set-up parameters can be adjusted in the field using built-in switches and an LED display. If required, Sabre II can also be configured and adjusted remotely using the integral serial communications ports and optional software tools.

Sabre II is especially useful for integration with third party data collection and alarm management systems. It provides facilities for external alarm threshold adjustment as well as additional input/output for connection of sensors or control devices.
