Perimeter and pipeline security
The field part is a passive fibre-optic linear detector: nothing but cable in the field, no electronics and no power. That is where reliability and simple operation come from.
How it works
We design, build and support. The field part is a passive fibre-optic linear detector: nothing but cable in the field, no electronics and no power. That is where reliability and simple operation come from.
Perimeters from 10 km
One indoor processing unit monitors the whole line and shows the zone of the event. A person is detected on approaching within 5–7 m of the cable; climbing over and digging under are detected by the impact on the fence.
Pipelines of any length
The cable along the route registers people approaching, machinery at work and digging, and points to the zone. An excavator or a drilling rig is detected by ground vibration on approach, before it touches the pipe.
No power or electronics in the field
Only cable on the route: no cabinets, UPS, lightning protection or heating. Nothing to service or repair in the field.
Integrated security of large areas
CCTV with alarm verification by cameras, events sent to the control room and integration with existing security systems.
What the system detects
The cable senses vibration and pressure in the ground and on the fence; the processing unit distinguishes events by the nature of the signal and shows the zone on the site plan.
A person at the line
Approaching within 5–7 m of the cable, climbing over, digging under, breaching the fence fabric.
Vehicles and groups of people
A vehicle stopping at the fence and a group on foot are distinguished from a single intruder by the nature of the signal.
Earthmoving machinery
An excavator, a bulldozer or a drilling rig: detected by ground vibration on approach to the pipeline, in advance, before the pipe is damaged.
Manual digging and tapping
Mechanical impact on the ground and the pipe at the point of work is registered with the zone indicated.
Zone of the event
The system shows the zone of the line on the plan, the cameras turn to it and the operator verifies the alarm.
Interference filtering
Wind, rain, animals, traffic on a road near the line: sensitivity and algorithms are tuned by zone.
A pipeline alarm: what the control room sees
A long route on one screen: the alarm arrives with the event type and the route kilometre, the section is marked on the pipeline diagram, and the camera at the nearest node shows the spot.
Event type
The processing unit tells events apart by the signal pattern: people approaching, machinery at work, digging. The alarm arrives with the event name, not just as a trigger.
Route kilometre and section
The event is tied to the route kilometre and shown on the pipeline diagram together with the nearest node. The duty crew drives to the section instead of searching the whole route.
Camera confirmation
The camera at the nearest node turns to the section and the operator confirms the alarm from the image; thermal cameras cover unmanned sections.
Event log
Time, section, operator actions and alarm closure are logged for review and reporting.
Who it suits
Sites with a long line, unmanned sections and routes where power and electronics in the field mean constant cost and risk.
Oil and gas
Trunk and field pipelines, tank farms, oil and gas fields.
Power industry
Substations, power plants, hydraulic structures; perimeters tens of kilometres long next to high-voltage equipment.
Mining
Open pits, tailings facilities, industrial sites in uninhabited terrain.
Transport and logistics
Airfields, railway facilities, terminals and warehouses with large grounds.
Industrial sites
Plants, water mains and intakes, sites with a long fence.
What the customer gains
No infrastructure in the field
No power lines, cabinets, UPS or lightning protection along the line. Nothing in the field to service and nothing to steal.
One unit for tens of kilometres
An indoor processing unit monitors the whole line; expansion means adding zones, not new guard posts.
Damage is prevented, not recorded
Machinery at the pipeline is detected on approach, before tapping or a rupture. The duty shift goes to the zone instead of searching the whole route.
Fewer false alarms
Tuning by zone and verification by cameras: the security team responds to real events.
Immune to interference
Fibre-optic cable is insensitive to electromagnetic interference and lightning strikes, so it suits substations and routes next to power lines.
Fits into existing security
Events in the control room, the access control system and CCTV without replacing the systems already in place.
What we do
- Fibre-optic linear detectors: passive, no power or electronics in the field
- Perimeters from 10 km: fences, digging under, climbing over, breaching the fence fabric
- Pipelines of any length: digging, machinery at work, people approaching, illegal tapping
- Detection of a person approaching within 5–7 m of the cable
- Early detection of earthmoving machinery at a pipeline
- Event localisation with the zone shown on the site plan
- CCTV with alarm verification by cameras, thermal cameras for unmanned sections
- Events to the control room, integration with security and access control systems
- Communication links to the processing units: fibre, radio
- Sensitivity tuning by zone: wind, animals, traffic near the line
- Design, installation, commissioning, training of operators and the security team
- Support: line checks, scheduled maintenance, system expansion
How the work goes
Survey
The route of the line, type of fence or ground, sources of interference such as roads, animals and wind; locations for processing units and cameras.
Design
Line diagram by zone, cable route, processing units, CCTV, communication links, specification.
Installation
Cable laying along the fence or in the ground, splice closures, installation of processing units and cameras.
Tuning and testing
Sensitivity calibration by zone, simulated intrusions under a test programme: approach, climbing over, digging under, machinery at work; a report.
Support
Line checks, scheduled maintenance, operator training, system expansion.
Typical tasks
A plant perimeter tens of kilometres long
A passive fibre detector along the fence, one indoor processing unit.
A pipeline through uninhabited terrain
The cable along the route registers impact and points to the zone; machinery is detected on approach.
Alarms need verification
We add CCTV with output to the control room.
False alarms from wind and animals
We tune the sensitivity and algorithms by zone; disputed events are verified by cameras.
No power along the line
A passive detector: nothing but cable in the field; only the indoor processing unit needs power.
Several sites in different regions
One control room: events from all lines in one log with site plans.
What the customer receives
Line diagram
Site plan with zones, cable route, processing units, cameras, communication links.
Specification and settings
Equipment, sensitivity parameters by zone, integration diagram with security systems.
Test reports
Simulated intrusions by zone, acceptance reports, instructions for operators and the security team.
Result: a line with the alarm zone indicated, CCTV and events in the control room.
Questions
At what distance is a person detected?
On approaching within 5–7 m of the cable; earthmoving machinery at a greater distance, by ground vibration. The values for a specific site depend on the ground and the method of installation and are confirmed during commissioning.
How does the detector tell an intruder from the wind?
By the nature of the impact on the cable. The processing algorithms are tuned by zone during commissioning, and disputed events are verified by cameras.
What needs servicing in the field?
Only the cable, and it is passive: no electronics and no power. The indoor processing unit and the cameras are serviced.
How long can the line be?
Perimeters from 10 km and pipelines of any length: the line is divided into sections, each served by its own processing unit.
Can it be connected to an existing security system?
Yes. Events are sent to the control room and to existing systems over standard interfaces, and alarms are verified by cameras.
