Senstar Sensor Fusion Engine

Perimeter Security Evolved

The Senstar Sensor Fusion Engine is a breakthrough perimeter intrusion detection 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.

Senstar Sensor Fusion = Informed, Intelligent Decisions 

  • Defeat nuisance alarms while maximizing detection capabilities 
  • Provide a greater context for threat determination by synthesizing low-level data from video analytics and perimeter sensors  
  • Map intrusion event locations to live video for geo-spatial awareness 
  • Compare active events to historical data (time, magnitude, and location information) 
  • Reuse existing perimeter and video surveillance infrastructure 
  • Scale to sites of any size

Drop-In Solution 

Pre-installed on a physical security appliance (PSA), the Sensor Fusion Engine can be used as a drop-in solution and integrates with existing security and video management systems (SMS/VMS).  In this configuration, the Sensor Fusion Engine’s operation is transparent to the SMS/VMS — the SMS/VMS receives intrusion alarms from the PSA instead of individual alarms from its video analytics or fence sensors, thus eliminating major sources of nuisance alarms.

Senstar Symphony™ Common Operating Platform 

Sensor fusion may be deployed within the full-featured  Senstar Symphony Common Operating Platform, a modular solution for security management and data intelligence. In addition to being an open, highly scalable video management system with built-in video analytics, it includes full-featured access control and perimeter intrusion detection modules. Sensor fusion alarms are graphically displayed on a map and can be used to trigger camera callups and customizable rules.

Sensor Fusion Features and Benefits

About 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. 

Benefits of Sensor Fusion 

  • Reduce Nuisance Alarm Rate (NAR) and False Alarm Rate (FAR) 
  • Improve Probability of detection (Pd) and Confidence Level (CL) 
  • Outperform third-party Boolean logic integration in many scenarios 
  • Lower operating and maintenance costs 

Defeat Nuisance Alarms from Video Analytics 

Sensor fusion defeats nuisance alarms and avoids the performance issues often associated with video analytic or video content analysis, including:  

  • Spiders building a web in front of the camera 
  • Water reflections (puddle) 
  • Flashlights, car headlights, or sunlight glare (for thermal cameras) 
  • Reflections from metallic objects and puddles (clouds) when using thermal cameras 
  • Existing security lighting causing reflections during rain and snow fall 
  • Vegetation movement 

Defeat Nuisance Alarms from Fence Sensors

When the Sensor Fusion Engine synthesizes signal response data from outdoor fence-mounted sensors with video analytic data, nuisance alarms generated by wind or debris are virtually eliminated while the benefits of the fence-based system, namely its high probability of detection, precise intrusion location information, and well-defined line-of-detection are maintained.
