Overview
Senstar Corporation is a Canadian security-technology brand headquartered in Ottawa, Ontario. It develops and manufactures systems intended to detect, assess, and manage threats around protected sites and within security operations. Its portfolio covers perimeter intrusion detection, fiber-optic and fence-mounted sensors, buried detection systems, intelligent security lighting, video analytics, video management software, access-control functions, and personal duress systems. The company traces its origins to 1981, when it was established as a spin-off from the Computing Devices Division of Control Data Canada. Its early technology included Sentrax, a ported coaxial-cable sensor designed to identify disturbances along a protected boundary. Early users included the United States military and Correctional Service Canada, helping establish Senstar's position in high-security environments. Over time, its systems were deployed at correctional facilities, military installations, airports, seaports, nuclear and electrical infrastructure, border facilities, government and diplomatic sites, and private estates. Senstar's product strategy combines physical perimeter sensing with software-based situational awareness. Its FiberPatrol family uses optical-fiber sensing and distributed acoustic-sensing principles to detect and locate disturbances along fence lines, walls, or buried cable routes. The approach is suitable for long perimeters where conventional point sensors may be difficult to deploy or maintain. Its fence-mounted products use cable-based detection technologies for high-security fences and temporary or permanent installations, while OmniTrax uses a buried electromagnetic field to create a volumetric detection zone below ground. The company has also expanded beyond conventional intrusion sensors. The LM100 combines LED perimeter lighting with accelerometer-based intrusion detection, allowing lighting and detection functions to operate as an integrated system. Senstar's software portfolio includes Senstar Symphony, an open video-management platform that supports video monitoring, recording, event management, intrusion monitoring, and access-control functions, including integration with ONVIF-compatible network cameras. Video analytics offerings have included people and vehicle tracking, automatic license-plate recognition, facial recognition, indoor tracking, and PTZ camera auto-tracking. Senstar's corporate development has involved multiple acquisitions and consolidations. Magal Security Systems acquired Senstar in 1997 after Senstar had become part of the Dornier Group of Daimler-Benz in 1994. Magal subsequently brought together Senstar with Perimeter Products, Dominion Wireless, Optellios, and Aimetis-related capabilities. These combinations broadened the business from perimeter sensors into personal duress systems, fiber-optic sensing, video analytics, and video management. In 2023, Magal sold its projects division to Aeronautics, a subsidiary of Rafael Advanced Defense Systems, while the remaining Senstar business was renamed Senstar Technologies Ltd. In February 2025, Senstar acquired Blickfeld GmbH, a producer of three-dimensional LiDAR sensors, further extending its sensing portfolio. Today, Senstar presents itself as a provider of integrated physical-security technologies rather than as a single-product sensor manufacturer. Its systems are designed for customers that require layered protection, combining detection at the perimeter, video verification, lighting, access management, and response workflows. The business serves public-sector, defense, corrections, transportation, utilities, industrial, commercial, and residential-security applications across international markets.
History
Senstar began in 1981 as a spin-off of the Computing Devices Division of Control Data Canada. Its early work centered on perimeter-security sensing, including Sentrax, described as an early ported coaxial-cable sensor. The technology was adopted in demanding environments, including by the United States military and Correctional Service Canada, where buried detection systems were installed at correctional facilities. In 1994, Senstar was acquired by the Dornier Group of Daimler-Benz. Three years later, in 1997, it was sold to Magal Security Systems. Magal had previously acquired Stellar Security Systems, a manufacturer of electrostatic-field and triboelectric fence sensors. Following the transaction, the North American operation used the Senstar-Stellar name while Senstar remained the principal name in European operations. In 1998, Magal acquired Perimeter Products, a producer of fence-mounted and bistatic-microwave sensors; that company initially continued as a separate entity. Senstar's portfolio expanded through further acquisitions. In 2003, Senstar, acting through Perimeter Products, acquired Dominion Wireless, a manufacturer of personal duress systems. Senstar, Perimeter Products, and Dominion Wireless were consolidated at the Ottawa headquarters in 2009 under the Senstar name. In 2014, Magal acquired Optellios, a company specializing in long-range fiber-optic sensors, and integrated its capabilities into Senstar's operations. In 2016, Senstar amalgamated with Aimetis, a Waterloo-based company known for artificial-intelligence video analytics and video-management software. This combination strengthened Senstar's ability to offer software and video intelligence alongside perimeter hardware. The resulting business developed a layered security portfolio. FiberPatrol used optical-fiber sensing and distributed acoustic-sensing principles to identify and locate disturbances along cables installed on fences, walls, or underground. OmniTrax provided buried volumetric detection using ported coaxial cable and an electromagnetic detection field. Fence-mounted cable systems addressed high-security applications such as correctional facilities, seaports, and temporary military camps. The LM100 combined intrusion detection with intelligent LED lighting, while personal duress systems served correctional institutions in Canada and the United States. Senstar also developed and marketed Senstar Symphony, an open video-management platform supporting video monitoring, recording, event management, intrusion monitoring, and access control. Its analytics portfolio included functions for tracking people and vehicles, automatic license-plate recognition, facial recognition, indoor tracking, and PTZ-camera auto-tracking. In 2020, the company introduced Safe Spaces, a product line intended to help organizations use video analytics in support of COVID-19-related public-health procedures. In 2023, Magal's projects division was sold to Aeronautics Ltd., a subsidiary of Rafael Advanced Defense Systems. Following the transaction, the remaining company was renamed Senstar Technologies Ltd. The business continued to focus on security products rather than project-delivery activities. In the same year, Senstar launched MultiSensor, a compact product using several detection modalities and embedded sensor-fusion processing. In February 2025, Senstar acquired Blickfeld GmbH, a producer of three-dimensional LiDAR sensors. The acquisition indicated continued movement toward combining multiple sensing technologies in a single physical-security platform. Senstar's customers and application environments include critical infrastructure, military facilities, nuclear power plants, airports, borders, correctional institutions, government buildings, diplomatic residences, electrical utilities, cannabis facilities, seaports, and private estates. The company participates in industry organizations including ONVIF, the Canadian Security Association, the Security Industry Association, and ASIS International.
