Intrusion Detection

Bandweaver utilises Perimeter Intrusion Detection Systems (PIDS) to ensure that organisations are fully secure and to help reduce operational risk.

With ever increasing threat levels it is important that organisations properly secure their assets. This starts at the perimeter of their sites where there has never been a more important time to deploy robust, reliable and secure detection strategies to mitigate operational risk.

Prompt and highly accurate location information of a would-be intruder ensures a fast and appropriate response to minimise any loss. Ensuring that your perimeter intrusion detection system is fully integrated into your security solution provides real time data. Therefore creating the ability to track and respond to intruders.

Fiber optic technology is fast becoming the technology of choice. Especially for those organisations looking to deploy a cost-effective reliable solution with significantly lower full life cost of ownership.

Bandweaver’s advanced range of fiber optic intrusion detection solutions provide both covert buried and fence or wall mounted detection capabilities from a single detection unit. With fully scalable systems for sites less than 5km to more than 100km Bandweaver has the solution for you.

BENEFITS

Resistance to Cable Cut & Sabotage

All Bandweaver PIDS detection units are offered with a minimum of 2-channels. When redundant loop configurations are installed the systems will continue to provide uninterrupted detection along the perimeter, even if the cable is cut or damaged.

Minimising Nuisance Alarms

Using advance algorithms incorporating AI technology, our market leading detection algorithms are able to develop an acoustic fingerprint of different events. This enables the distinction between genuine security risks and extraneous environmental noise.

Location Accuracy

Advanced signal processing technology combined with intelligent algorithms enables fast and accurate identification of the specific location of a potential threat to within ±5m.

Multiple Fence Types

Due to its unique configuration capabilities, the Bandweaver solution is suitable for every fence type without compromising location accuracy or event classification capability.

Lower Cost of Ownership

Overall reduced cost of installation and maintenance when compared with alternative technologies. Additionally, no power infrastructure is needed in the field.

Integration

Our advanced software is capable of seamless integration with a wide variety of commonly used 3rd party systems (PSIM, VMS, BMS etc.). This provides operational teams with real-time information from a range of devices via a single interface.

Cut Resilience

Fiber optic cable perimeter intrusion detection offers a simple to install solution that has no requirements for power in the field which reduces the overall cost of ownership. With fan free technology, no moving parts and utilising high reliability telecoms components this equates to high percentage uptime ensuring years of reliable detection capability. With a location accuracy of intrusion events to ±5m it enables the ability to rapidly react to any perceived threat.

Response to Multiple Alarms

Multiple alarms may be a deliberate diversion caused by a potential intruder. Consideration should be given, therefore, to how multiple alarms will be stacked or queued by the entire system, or for an individual zone, and whether alarms from particular zones should be given higher priority.

DAS systems can configure multiple smart zones, with user configurable alarms for each zone which can be adapted as the environmental conditions evolve to prevent nuisance alarms from such events. They can also detect multiple events at once and so this makes it more challenging for the intruder to attempt diversionary tactics.

Covert Buried detection

Our buried solution is totally covert and can detect personnel and vehicles long before they gain access to a site and is ideal where there is a lack of physical delineation.

TYPES OF SYSTEMS

Fence mounted intrusion detection

Bandweaver optical fiber detection is suitable for all a wide variety of fence types including chain link, weld mesh, and palisade. With advanced event classification the system can detect multiple simultaneous intrusion attempts with location accuracy down to ±5m.
Fence climbing, cutting and lifting are all detected with a probability of detection (POD) greater than 95%. Alongside this, the intelligent processing ensures that there are minimal nuisance alarms.
There is no requirement for power in the field and optical fiber cabling is unaffected by electromagnetic interference. The cabling itself is intrinsically safe so is suitable for sites that are at risk from fire or explosion.

Wall Mounted Intrusion Detection

Bandweaver’s optical fiber detection is suitable for wall mounting and will detect intruders climbing over or attempting to break through a wall. This makes it suitable for both perimeter and building walls.
Optical fiber cable can also be deployed on wall toppers such as barbed or razor wire to ensure full site detection capability. Our advanced signal processing minimises nuisance alarms caused by environmental background noise.

Covert Buried Intrusion Detection

Direct buried optical fiber cable can be deployed to protect perimeters where there is no physical delineation or a sterile zone configuration. With the ability to detect intruders before they enter site whilst remaining covert buried detection has a number of significant advantages over other technologies.

With the ability to distinguish between multiple intruders and vehicles the buried intrusion detection solution is a fast to deploy, low cost but highly resilient solution and is suitable for all soil types, it is especially suitable for protecting extended borders

Rapidly Deployable

PIDS that are designed for temporary deployment; for example, to protect a mobile asset. Typically this would cover military applications, and again, DAS sensing technology has been very successfully deployed in these environments.

Solutions Selection Guide

When deciding on the specification and selection of any perimeter intrusion detection systems, the following factors must be taken into consideration:

 

  • Landscape, flora, fauna and topographical features
  • Integration with other types of equipment or systems
  • Climatic conditions
  • Local regulations
  • Presence (or lack of) physical barrier and robustness against threats
  • Duration of required deployment (rapidly deployable PIDS)
  • Response force arrangements
  • Personnel on site

All of these factors will affect the key choices made by an organisation, and there are also other points to consider, including:

  • Whether a line-of-sight technology is appropriate (e.g., radio wave-based technology or camera-based systems). For instance, are there any undulations in the ground surface? Undulations occurring over the distance of a metre and up to several tens of metres can shield the presence of an intruder from some detection technologies, particularly in the case of microwave systems, visual cameras and active or passive infrared.
  • Does the detection system need to be covert (buried or hidden)?
  • Are there specific electromagnetic interference issues that will affect specific technologies, or are there requirements for the technology to be intrinsically safe (e.g., on oil rigs or process plants)?
  • Is there existing infrastructure to mount the system, or will it be part of a new build?
  • How does the system integrate with the overall security strategy?What constitutes an alarm, and what action is taken in the event of an alarm (audio alarm, visual alarm or a combination)?

In some scenarios, particularly where perimeters are large or the asset is critical, the asset owner may choose to use multiple technologies and integrate the respective monitoring systems through a centralised control system (e.g., video cameras combined with DAS, where the cameras slew to the specific event when an alert is raised.)

Perimeter Intrusion Threat Types

As mentioned above, DAS systems are able to classify events according to their acoustic signatures. Typically the types of classifications that are required in most intrusion scenarios include:

Personnel movement

The systems can detect personnel walking and monitor the cadence of the footfall, enabling identification of personnel walking within the vicinity of the cable. Typically for walking, this can be alerted within 5 m of the cable.

Vehicle movement

Vehicles can be detected, classified as a vehicle  and tracked using a DAS system. Depending on the size of the vehicle, these can be detected within 10-20 m from the cable.

Digging  (manual or mechanical)

Digging, whether it is a person or a mechanical machine, imparts rhythmic and high-energy bursts into the ground and has a clear signature. The typical range is from 5 to 50 m, depending on whether it is a person digging or on how large the specific mechanical digger is.
