AI-Powered Multi-Sensing Detection System

Senstar MultiSensor Cascade Plus is a compact, AI-powered system that leverages the power of sensor fusion to intelligently detect and characterize intrusions while virtually eliminating nuisance alarms. Support for device daisy-chaining and third-party PoE devices reduces costs while enhancing site resiliency.

Detecting intruders at the perimeter, before they can enter buildings or sensitive areas, is a critical part of any security plan. Conventional sensor technologies focus on detecting specific physical phenomena, which can lead to false positives or missed detections. Senstar MultiSensor takes a revolutionary approach with its embedded Sensor Fusion Engine, synthesizing data from multiple sensing technologies (short-range radar, PIR, accelerometer, high frequency vibration, and video) to understand the full context of an event, resulting in the highest probability of detection while virtually eliminating nuisance alarms.

This context-based approach assists security personnel with improved situational awareness by providing real-time location tracking, presence detection, and ground-level images of the event.

Unmatched Performance via AI-Powered Sensor Fusion Engine

The Senstar MultiSensor's Al-powered Sensor Fusion Engine performs a threat analysis based on data from each sensor, considering intrusion training data, pattern analysis, relevance, history, and background noise. This enables reliable intrusion detection under difficult conditions and against skilled adversaries, including low light, high winds, rain, snow, fog, and stealth attacks.

A high Probability of Detection (Pd) is crucial, but the Nuisance Alarm Rate (NAR) is equally important. A high NAR can lead to complacency or system mistrust. Senstar MultiSensor Cascade Plus is designed to virtually eliminate nuisance alarms while maintaining the highest Pd.

Lower Total Cost of Ownership (TCO)

Senstar MultiSensor lowers TCO by dramatically reducing infrastructure and installation costs. Its PoE In/Out ports enable multiple devices to share the same network connection, with up to 16 devices daisy-chained together. The PoE ports can also connect third-party devices like surveillance cameras, IP speakers, two-way intercoms, and security lighting.

Simplify Site Upgrades

The PoE In/Out ports on Senstar MultiSensor enable site owners to easily upgrade security by re-purposing existing Ethernet cabling. Devices can be connected anywhere with existing PoE camera infrastructure, reducing the need for additional holes or cable runs.

Network & Power Resiliency

For network and power resiliency, dual Ethernet switches can be connected to each end of the daisy chain, ensuring continuity of protection even if a cable is cut or a device fails. For unmanned/remote sites, the PoE Out and relay output ports can control local deterrence devices independently of the site's backhaul network connectivity.

Integrated Security Network

Senstar MultiSensor can integrate with other Senstar devices and software, including FlexZone®, FiberPatrol®, Senstar LM100™, and UltraWave™. Senstar's Network Manager™ software conveys alarm and status information to a security/video management system (SMS/VMS).

Easy to Install and Maintain

Senstar MultiSensor Cascade Plus is easy to install and requires virtually no maintenance. Its mounting bracket supports various installation options, including fence posts, walls, light/camera posts, and tower structures. The low-voltage device uses Ethernet for communications and power. When retrofitting sites with existing IP camera networks, existing wiring can be reused, avoiding costly new cable installations.

Enhanced Situational Awareness in Senstar Symphony™

When deployed with the Senstar Symphony Common Operating Platform, Senstar MultiSensor enhances a security operator's situational awareness. Operators can:

• View alarm location on site maps.
• View live and recorded video from the Senstar MultiSensor's 180° image sensor, including Picture-in-Picture (PIP).
• View on-map thumbnails of the most-recent captured image.
• View real-time device status.
• Mask or unmask the device as required.

Sensor data from Senstar MultiSensor can flag activity in Symphony's video timelines. Flagged video segments can be used to auto-generate summary videos and quickly view or export video captured before and after an alarm event.

Automate On-Site Security Response

By virtually eliminating nuisance alarms, Senstar MultiSensor enables intelligent automation of on-site security responses. It provides a higher level of system confidence, allowing site owners to deploy automated deterrent mechanisms without creating operational burdens. Using its Sensor Fusion Engine, Senstar MultiSensor can trigger Senstar Symphony events, such as:

• Enabling/disabling additional security lighting.
• Playing automated messages over loudspeakers.
• Sending email or SMS alert messages with linked images.
• Generating alarms on mobile devices.

Mobile App Support

Senstar MultiSensor is fully supported in the Senstar Symphony Mobile app (iOS and Android). Users can view alarms and live/recorded video from multiple sites.

Applications

With its compact design, multi-sensing capabilities, and network cable daisy-chaining, Senstar MultiSensor can detect activity in various cost-effective applications, trigger cameras, and generate images for improved situational awareness.

Fence Sensor

Mounted to a fence post, Senstar MultiSensor detects the approach of a potential threat and any attempt to breach the fence fabric.

Tower Climb Detection

Mounted on tower structures, Senstar MultiSensor detects activity at the base and attempts to climb the structure.

Doors and Loading Docks

Installed above doors or loading docks, Senstar MultiSensor detects the arrival and departure of vehicles and people, as well as the opening and closing of doors.

Asset Protection

Ideal for protecting a range of assets in barrier or barrier-free (open area) applications.

Configuration

Senstar MultiSensor is configured over the network using its Configuration Wizard or the Universal Configuration Module (UCM) software. The software communicates with Senstar devices via the Network Manager gateway software, enabling installers to visually view detection performance and calibrate the system.

The easy-to-use Configuration Wizard guides users through the configuration process, including application type, detection zones, daisy chain support, and network configuration.

Deployment Configurations

Entry/Asset Protection

Example deployment monitoring an entrance or asset. Senstar MultiSensor tracks and pre-alarms intruders within an 8 x 5 m (26 x 16 ft) area. Alarms are generated when an intruder approaches within 2 m (6.5 ft). This configuration also shows the ability to use Senstar MultiSensor Cascade Plus as a drop-in retrofit solution, sharing a network connection with an existing PoE surveillance camera.

Perimeter Protection

Example deployment with multiple Senstar MultiSensors monitoring a perimeter fence or wall. Each device tracks and pre-alarms intruders approaching the fence. Alarms are generated when the intruder attempts to breach the fence. Devices are daisy-chained for a single network connection.

Area/Open Gate Protection

Example deployment monitoring a non-barrier area or open gate. Each device tracks and pre-alarms when intruders approach a virtual barrier, loiter, or pass through. Devices are daisy-chained, with cabling trenched between them, requiring only one network connection.

Daisy Chain and Accessory Power Considerations

The MultiSensor supports Power over Ethernet (PoE) daisy chain configurations using a PoE switch or the MultiSensor PoE Injector accessory. Senstar MultiSensor negotiates as a PoE Class 0 device, providing approximately 13W to the first device. The number of connected devices depends on the PoE device used:

• PoE Switch: Up to 2 daisy-chained MultiSensors.
• MultiSensor PoE Injector: Up to 16 daisy-chained MultiSensors, assuming 6-meter spacing (creating a 100 m sensor segment consistent with industry-standard perimeter intrusion zoning practices).

Redundancy

For system resilience, the MultiSensor daisy chain supports dual-supply redundant configurations with DC power supplies and network switches at both ends of the 16-unit segment. Network switches must support Rapid Spanning Tree Protocol (RSTP) with proper port configuration to prevent data collisions. This redundant architecture delivers automatic failover capabilities when a cable is severed or a unit fails, as RSTP intelligently manages the routing table to determine the active data path and maintains communication to all sensors via the alternative route.

Accessory Power

The MultiSensor's PoE Out port can function as a switched power output for attached devices in standalone configurations, enabling direct powering of accessories like security lighting that operates at 48V DC (nominal). The available power depends on the upstream power source. When MultiSensors are configured in cascade mode, the PoE Out port exclusively functions as a network port for data transmission to downstream units; separate power supplies must be used for any connected external devices.
