Enterprise Perimeter Intelligence
AirezSense™ FoRiTurning Vibration into Visibility.
A patented fiber-optic perimeter intelligence system that transforms micro-vibrations into real-time situational awareness through the AIREZ Physical Intelligence Layer.
What is AirezSense?
The ground, the fence and the pipeline become the sensor.
AirezSense FoRi is a patented fiber-optic sensing platform that detects vibrations, footsteps, vehicles, digging, cutting, and other physical disturbances across critical infrastructure.
Integrated with AIREZ, these signals become contextual intelligence rather than isolated alarms.
How it works
Four stages between a disturbance and a decision.
Each stage narrows uncertainty. What begins as a micro-vibration in a strand of glass arrives in the operations centre as an understood situation with a recommended response.
- 01
Fiber Optic Sensing
A single fiber run becomes thousands of continuous virtual sensors, reading the interference pattern created by any disturbance along its length.
- 02
Edge Processing
Signals are classified locally, within metres and milliseconds, so bandwidth carries conclusions instead of raw waveform.
- 03
AIREZ Sensor Fusion
The vibration event is corroborated against thermal, radar, camera, LiDAR and access-control state to resolve what actually happened.
- 04
Situational Awareness
The GSOC receives one located, scored, explainable event — with the response already recommended and the evidence attached.
Built for critical infrastructure
Where a missed disturbance becomes a national-scale consequence.
The same fiber, the same platform, tuned per environment. Hover any environment to see how the sensing field re-focuses around it.
Defense
Covert detection fields where visible infrastructure is a liability.
Military Bases
Layered perimeter awareness across large, partially unfenced installations.
Border Security
Wide corridors monitored without revealing where detection occurs.
Pipelines
Right-of-way protection against digging, tapping and third-party strike.
Utilities
Substation and generation perimeters with no RF footprint.
Airports
Airside fence lines, tunnels and service corridors under continuous watch.
Ports
Quays, gates and container yards where the perimeter is always in motion.
Rail
Track intrusion, cable theft and structural disturbance across long routes.
Data Centers
Fence, conduit and structural integrity monitored down to the metre.
Correctional Facilities
Climb, cut and tunnel activity classified before it becomes an escape.
Corporate Campuses
Discreet perimeter awareness that never looks like a security cordon.
Remote Infrastructure
Unmanned assets that report themselves, on minimal bandwidth.
Sensor fusion
One sensor inside a much larger intelligence.
AirezSense is never asked to be certain on its own. Select any node to see the relationship AIREZ uses to turn a vibration into a conclusion.

What can it detect?
Twelve classes of physical disturbance, continuously.
Every detection is located along the fiber run, timestamped, classified and scored — not reported as a zone-level alarm.
Footsteps
Individual gait signatures, including deliberate slow approach.
Vehicle Movement
Class, direction and speed along or across the sensing line.
Digging
Manual and mechanical excavation near buried assets.
Tunnel Activity
Subsurface boring and spoil movement beneath the perimeter.
Fence Climbing
Load and flex signatures distinct from wind or animal contact.
Fence Cutting
High-frequency cut events isolated to the exact span.
Mechanical Failure
Bearing, pump and structural anomalies before they cascade.
Explosions
Blast events located instantly across the full run.
Ground Vibrations
Seismic and construction activity separated from threat activity.
Tampering
Interference with the fiber, enclosures or connected infrastructure.
Pipeline Disturbances
Third-party strike, tapping and unauthorised excavation.
Perimeter Breaches
Confirmed crossings, corroborated across the sensing stack.
Why fiber?
A perimeter that cannot be seen, jammed or mapped.
Conventional perimeter sensing announces itself. Fiber is passive glass in the ground — there is nothing to detect, defeat or maintain in the field.
Traditional Sensors
AirezSense FoRi
Passive
Powered devices at every point of detection
Passive glass; sensing electronics live in one secured cabinet
RF emissions
Emits, and can be located by what it emits
No RF emissions along the entire sensing run
EMF immunity
Susceptible to electrical and industrial interference
Immune to EMI, EMF and lightning-induced noise
Detectability
Visible cameras, poles and enclosures reveal coverage
Undetectable — an adversary cannot map what they cannot see
Distance
Zone by zone, device by device
Long-distance continuous sensing over tens of kilometres
Deployment
Overt infrastructure requiring visible build-out
Covert deployment in existing conduit, fence fabric or trench
Maintenance
Field devices to power, clean, calibrate and replace
Low maintenance; no field electronics to service
Scalability
Linear cost per additional point of detection
Highly scalable — extend the run, extend the intelligence
AI-driven classification
It does not simply detect. It understands.
Every disturbance is classified against known signature classes, corroborated across the sensing stack, then scored and paired with a recommended response.
Threat Score
Hover a classification to see how the score and response change.
Recommended Response
- 01Suppress — explained by environment
- 02Monitor — corroboration pending
- 03Cue camera and verify
- 04Dispatch and escalate to a person in authority
Enterprise security
Built to pass the review before it passes the perimeter.
Encrypted Communications
In transit and at rest, across every hop from edge to GSOC.
Edge Processing
Classification happens on site; raw signal never has to leave it.
Role-Based Access
Scoped visibility per agency, per site, per role.
Audit Logs
Every conclusion, action and override is attributable and retained.
Government Ready
Architected for federal and defense deployment requirements.
Scalable Architecture
One site or a national network, on the same platform.
Low Bandwidth
Conclusions on the wire, not waveform — viable on austere links.
Real-Time Analytics
Sub-second location, classification and operator presentation.
Commercial deployment
Available as infrastructure, intelligence, or both.
AirezSense is deployed as a complete programme or as a layer inside an existing security architecture.
