PrismaHedge

Perimeter Control

PrismaHedge, Prisma’s next-generation smart solution for intrusion protection at the perimeter, uses its patented Hyper-Scan Fiber-Sensing™ technology enabling ultra-sensitive and intelligent-learning detection to provide real-time intelligence and uniquely reliable monitoring capabilities.

PrismaHedge - Perimeter Control

The solution lowers deployment costs by using standard, pre-deployed fiber-optic cables (including cables that were installed within a conduit). These fiber-optic cables, which are part of most modern infrastructures, operate as the system’s “sensors” and enable PrismaHedge to monitor and detect movement at the perimeter at remote locations, providing security for up to 100 km per PrismaHedge unit or 200 km per dual-unit.

PrismaHedge strengthens perimeter security and provides alerts regarding safety issues and intrusion detection in real time. It identifies the acoustic signature of each event at or near the perimeter, at a resolution that allows classification of the events and identification of their location – with unprecedented accuracy – as it dramatically reduces the “noise” of false positive and negative alarms.

Within a distance from the perimeter that you pre-define, PrismaHedge allows smarter, faster perimeter management and prevents suspicious activity by flagging for classification a range of events that can include:

  • Pedestrians near the perimeter

  • Pedestrians crossing the perimeter

  • Vehicles (light or heavy) operating near the perimeter 

  • Mechanical activities or manual digging near the perimeter

  • Suspicious activities including touching the fence, climbing over the fence, and ladder activity

  • Vandalism such as cutting the fence

  • Drones above the perimeter

Solution Architecture

PrismaHedge’s platform is Plug & Play – with zero infrastructure installation, and minimal maintenance. 


The platform provides monitoring for up to 100 km per PrismaHedge unit or 200 km per dual-unit. The unit is connected to the Command & Control (C&C) unit in the customer’s operating center. 

There is no need for discrete sensors. Upgrades are software based; no hardware upgrades are required.

The PrismaHedge unit attaches directly to the customer’s fiber-optic cable with a simplex SC/APC connector, which connects to a single fiber in the patch panel – ensuring access to a single fiber only, i.e., not compromising the activity or security of any other fibers in the cable. An Internet connection (LAN or WiFi) is required to transmit the monitored data to a C&C unit. 

Scaling up involves use of multiple PrismaHedge units, each of which provides coverage for up to 100 km. Each unit is located in a communication room. All of the units combined require a single C&C unit in the customer’s operating center.

Key Features & Benefits

Systems involving thousands of sensors along the border are expensive for deployment, operation, and maintenance. The alternative is fiber sensing - using very long fibers as sensors - which is probably the most cost-effective solution. But before PrismaHedge, existing solutions were ineffective due to high false alarm rates, poor target classification, and limited ability to use pre-deployed optical communication cables as "sensors".  

 

PrismaHedge solves all of all these issues thanks to its revolutionary Hyper-Scan technology, which offers 100x sensitivity improvement over alternative systems.

 

PrismaHedge has raw data of unparalleled quality. We apply Big Data techniques to data sets that are several orders of magnitude wider, with significantly higher SNR (signal-to-noise ratio) levels – leading to very high detection probability and advanced target classification. 

 

Upgrades to the system are software based and can be installed remotely.

All Information Consolidated in a Single Location & Single Display

The C&C unit presents the consolidated data of multiple units, with a real-time map and detection table that displays the following information:

  • Detection of events

  • Classification of events

  • Location of events at a high resolution 

  • Identification of multiple, simultaneous events without interference or crosstalk
