Senstar MultiSensor™: AI-Powered Multisensor Intrusion Detection System

February 10, 2025

A New Paradigm in Perimeter Security

A critical vulnerability of perimeter security systems lies in their inability to distinguish real threats from background factors, leading to a constant trade-off between missed intrusions and an overwhelming number of false alarms. Effective perimeter protection must not only register activity but also intelligently analyze it in the full context of the event.

Traditional detection technologies based on individual sensors have significant limitations — they only respond to specific physical phenomena, ignoring the full context of events, which leads to numerous false alarms or, worse, missed intrusions.

Senstar MultiSensor™ represents a radically new approach to security systems by using artificial intelligence and the principle of sensor fusion to create a comprehensive picture of perimeter activity. This compact system does more than just register individual incidents — it analyzes them in full context, combining data from five different sensing technologies to deliver unprecedented detection accuracy with virtually zero false alarms.

Intelligent Analysis and False Alarm Elimination

At the heart of the Senstar MultiSensor system is the built-in Sensor Fusion Engine that uses machine learning algorithms to perform multi-layered intelligent analysis of data collected from multiple sensing technologies:

1.

Short-range radar provides localized volumetric coverage, determining the intruder’s distance, direction, and size with high precision.

2.

Image sensor tracks individuals using built-in video analytics and generates panoramic images with a 180° field of view directly at the intrusion point.

3.

Dual PIR (passive infrared sensor) detects intruders in close proximity to the perimeter, distinguishing left and right-side movement.

4.

Accelerometer detects any physical interaction with the fence or mounting surface, instantly identifying tampering attempts.

5.

High-frequency sensor supplements the system with additional data on perimeter activity.

The Senstar MultiSensor data fusion engine goes far beyond simple data aggregation. It leverages advanced artificial intelligence algorithms for:

Analyzing behavior patterns of potential intruders

Evaluating the relevance of signals from different sensors

Considering historical intrusion data

Filtering out background noise and environmental influences

As a result, the system delivers the highest possible probability of detection (POD) with near-zero nuisance alarm rates (NAR), even in challenging conditions including low lighting, strong winds, precipitation, fog, and stealth attacks.

Deployment and Integration Flexibility

Network Capabilities

Senstar MultiSensor connects to the security network via Ethernet with Power over Ethernet (PoE) support, providing both data transmission and power through a single cable. The system integrates seamlessly into a unified network with other Senstar devices, ensuring comprehensive protection through intrusion detection, sensor integration, and signal management—enhancing the security of diverse facility types.

The Network Manager™ software transmits alarm and system status information to the Senstar Symphony™ security management platform or to third-party security systems and video surveillance solutions.

Mounting and Configuration Options

Thanks to its compact design and universal mounting bracket, the Senstar MultiSensor can be installed on a variety of surfaces:

Fence posts

Walls

Lighting poles

Camera masts

Tower structures

The optimal installation height is 2.4 to 3.7 meters above ground level, with a downward tilt of approximately 20° to ensure maximum detection zone coverage.

Deployment Scenarios

The system supports various deployment scenarios:

Asset/entry protection: 8×5 m detection zone with pre-alarm and final alarm at a distance of 2 m

Perimeter protection: cascading deployment along fences or walls with 6×5 m detection zones each

Open area/gate protection: virtual alarm line control for zones without a physical barrier

Integration with Senstar Symphony™: Enhanced Situational Awareness

When integrated with the Senstar Symphony common operating platform, the MultiSensor system transforms into a powerful tool for improving situational awareness. Security operators gain the ability to:

Visualize alarm locations on interactive site maps

View event image thumbnails directly on the map

Access live and recorded video from the MultiSensor panoramic image sensor

Correlate data with associated surveillance cameras

Monitor device status in real time

Flexibly manage detection zone masking as needed

Data collected from the Senstar MultiSensor automatically tags video recordings with corresponding activity, simplifying the creation of summary clips and the export of relevant footage.

Automated Response and Mobile Access

Intelligent Security Automation

Thanks to its high detection reliability and near-zero false alarms, the Senstar MultiSensor is an ideal solution for implementing automated response mechanisms. The system can initiate various automatic actions through the Senstar Symphony platform:

Activate additional security lighting

Broadcast warning messages via loudspeakers

Send email or SMS alerts with attached event images

Trigger alarms on security personnel’s mobile devices

Mobile Device Support

Senstar MultiSensor is fully supported in the Senstar Symphony mobile app for iOS and Android devices. This allows security personnel to receive alerts and view live or recorded video from multiple sites directly on smartphones or tablets, ensuring effective response even outside the main monitoring center.

Conclusion: A New Era of Perimeter Protection

Senstar MultiSensor represents a revolutionary solution for perimeter security, elevating intrusion detection reliability to a new level. Thanks to the unique combination of five sensor technologies with intelligent AI-based analysis algorithms, the system ensures:

The highest probability of detecting real threats

Virtually zero false alarms

Contextual understanding of events for enhanced situational awareness

Flexible deployment for various security scenarios

Seamless integration into comprehensive security systems

In a world where traditional detection systems face increasingly complex challenges, Senstar MultiSensor offers a new approach that combines the power of multisensor technology with artificial intelligence to create a truly reliable and intelligent perimeter protection system.
