Long perimeter coverage
One controller monitors up to 4 km of sensing fiber across four physical zones.

Why perimeter alarms fail
Most systems see the breach too late.
Cameras, beams, and microwave barriers can help confirm an event, but they often depend on line of sight, powered devices, clear weather, and operator attention. FortSense adds a passive sensing layer directly on the perimeter so security teams know where force is being applied before loss or sabotage spreads.
Detect cutting, climbing, lifting, digging, and forced entry attempts.
Keep detection active through fog, rain, dust, darkness, and high-EMI environments.
Send zone-level alarms to panels, VMS, monitoring centers, and custom software.
FortSense 4
A passive fiber optic PIDS controller for long perimeters.
FortSense 4 processes vibration signatures locally and converts perimeter activity into actionable alarms. Standard single-mode fiber stays passive in the field, while the controller integrates with the security systems already used by operators and integrators.

The perimeter cable is passive fiber, reducing power, maintenance, and tamper exposure.
EMI/RFI immune
Optical sensing works around substations, radar, motors, and lightning-prone environments.
Zone evidence
Security teams receive the affected zone instead of a vague motion or camera event.
Relay and IP integration
Connect through dry-contact relays, TCP/IP, webhooks, MQTT, VMS, and monitoring platforms.
Assisted calibration
Installers can simulate intrusion attempts and tune sensitivity to the site.

FAQ
Questions about fiber optic perimeter security
What is fiber optic perimeter security?+
It is a perimeter intrusion detection method that uses optical fiber as a sensing medium. Vibrations from cutting, climbing, digging, or forced entry are interpreted by a controller and converted into alarms.
Does FortSense require power along the fence?+
No. The sensing line is passive fiber optic cable. Power and processing stay at the FortSense controller, which reduces maintenance and field tamper points.
How far can one FortSense 4 controller monitor?+
One FortSense 4 controller monitors up to 4 km of sensing fiber across four independent physical zones. Larger perimeters can use multiple controllers.
Can FortSense work with existing cameras and alarm panels?+
Yes. FortSense can send events through relay outputs and IP integrations, so it can trigger cameras, panels, VMS platforms, and monitoring workflows.
Which sites benefit most from fiber optic PIDS?+
Critical infrastructure, utilities, logistics yards, airports, ports, refineries, solar farms, prisons, and remote sites benefit when early perimeter detection is more valuable than post-entry video confirmation.
