The FenceSentry series of Distributed Acoustic Sensors (DAS) are optimised for Perimeter Intrusion Detection (PIDS) and provides detection and location of intrusion events with minimal nuisance events and false alarms.

- Location of events to within 1m

- Based on single fiber optic sensing cable. No individual sensors, no metal or moving parts

- Robust and reliable instrumentation with no moving parts (fan free) and utilising high reliability telecom components

- Ability to react to precise location of event for rapid action and effective troubleshooting

- Easy to install and low cost of ownership with low ongoing maintenance costs

- High percentage system uptime (mean time between failures > 19 years) giving complete coverage at all times
