Perimeter Control

Uninterrupted monitoring of long-distance borders and perimeter control for enhanced safety and security

Mode of Operation

The need to protect strategically important military and civilian locations from unauthorized entry is increasing. This can be along a sparsely inhabited borders, around the perimeter of busy airports, protecting prisons or around other important objects. Distributed fiber-optic sensing delivers the most effective solution for these applications even in cases where there is no electrical power available.

Perimeter monitoring applications utilize acoustic and vibration-sensitive cables. They register noise and the vibrations caused by approaching objects. In this way, a trespasser can be detected and localized within 5 meters. With the application of two parallel sensor cables, the direction and speed of moving objects can be determined.

False alarms are avoided through the use of appropriate signal filters that suppress common sound and vibration patterns so that only relevant anomalies are processed. In addition to software filtering, the sensor cable can act as a bandpass filter through the proper selection of jacketing materials.

Sensor cables can also be integrated into fencing material in order to detect tampering or an unauthorized breach. Strain-sensitive sensor cables can be used for these applications.

Advantages

  • Long Distances: Monitoring of borders and perimeters up to 50 km in length per system
  • Maintenance-free: Sensor cables ensure decades of operation
  • Invisible: Non detectable border
  • No power supply needed: Securing electrically undeveloped boundary lines

Application Examples

Border Control

Fiber-optic sensing enables continuous border monitoring, in particular in remote, unguarded areas without utility access. Intrusions are real-time localized to within a few meters utilizing Google-Maps. Solifos’ maintenance-free cable solutions are fit-for-purpose for difficult and otherwise inaccessible terrain.

Critical Infrastructure Protection

Protecting critical infrastructure such as power stations, nuclear facilities, airports and high-speed rail lines is essential for avoiding service disruptions or catastrophic failures. Monitored distances are generally lower than border or perimeter control. However, the technical challenges of identifying an intruder as friend or foe is greater.

Prison Monitoring

Unlike perimeter and border control, prison applications ensure that prisoners do not leave an approved area and present a risk to society. The danger posed by an escape can be minimized by installing a fiber-optic sensing cable in a person-free zone. In this way, the challenge of friend or foe identification is elimintated.
