Sensor Fusion: Reduce Nuisance Alarms, Improve Probability of Detection

Individual perimeter security technologies have been pushed to the limit of performance in terms of Nuisance Alarms Rates (NAR), False Alarm Rates (FAR), Probability of Detection (Pd), and Confidence Level (CL), while integration, and system-level requirements (training, set-up, and support) remain on-going sources of potential operational issues.

Sensor fusion is the next evolutionary step.

What is Sensor Fusion?

Sensor fusion is the correlation and synthesis of data from different sensors to increase context for making decisions. It reduces setup complexity, defeats nuisance/false alarms, and ultimately gives users the highest level of confidence in identifying and detecting real threats.

Why Sensor Fusion?

  • Reduced NAR/FAR
  • Improved Pd and CL
  • Outperform third-party Boolean logic integration in a wide range of scenarios
  • Lower operating and maintenance costs

Senstar Symphony Sensor Fusion Engine

Senstar’s Symphony Sensor Fusion Engine is breakthrough technology that synthesizes data from separate systems to generate actionable information. More than just a simple Boolean logic integration, the sensor fusion engine accesses low level data to intelligently characterize potential risks. Data synthesis enables the system to achieve levels of performance that exceed those of the individual sensors. For security applications, this has direct, practical benefits, namely the ability to maximize the strengths of individual sensor technologies while avoiding their shortcomings. When signal response data from outdoor sensors is synthesized with video analytic data, nuisance alarms generated by wind or debris are virtually eliminated while maintaining the system’s high probability of detection.

To increase the context of understanding in order to make intelligent decisions, Senstar’s Sensor Fusion Engine can:

  • Map sensor event locations to live video for geo-spatial awareness
  • Synthesize low-level data from perimeter sensors and video analytics
  • Compare active events to historical data (time, magnitude, and location information)
  • Reuse existing perimeter and video surveillance infrastructure
  • Scale to sites of any size

Sensor fusion will be available as part of the Senstar Symphony™ Common Operating Platform, a modular solution for security management and data intelligence. In addition to be an open, highly scalable video management system with built-in video analytics, it includes full-featured access control and perimeter intrusion detection modules.
