QS-100 Seismic Acoustic Sensor System Overview

The Quantum Technology Sciences Single Channel System meets the demand for persistent movement monitoring, intrusion detection and situational awareness. This easy-to-install, low visibility system gives real-time alerts when human footsteps, vehicle movement or digging are present in the vicinity of one or more seismic-acoustic sensors.

Based on a nodal approach, each system includes a single processing node, a single concealable sensor, cabling, and power supply. This single channel system delivers the only situational awareness solution with a three dimensional 360º detection sensitivity in air, water and the earth.

Vibrations in the earth are gathered by the motion sensor and are analyzed immediately and automatically by the node. The sensor has an extended sensitivity range and does not require line of sight to its detected potential threat. If the system determines that the vibrations are from a selected potential threat source, for instance human footsteps, the node immediately notifies, by wireless or wired means, a remote base station or monitoring device. The notification includes the node identity and the type of potential threat detected.

Multiple nodes can be serviced by a single monitoring device, where the user interface is installed. Customer needs dictate the monitoring device such as a command center computer, remote laptop, digital assistant, or an existing security architecture.

The Single Channel System is a source of situational awareness when deployed at a boundary around a private property site, a valued industrial asset, a military or government property, a component of a critical public infrastructure, such as pipelines or pumping or power stations, or as a country’s border. It may function as a stand-alone product, or may be integrated with other products built by Quantum Technology Sciences or by other manufacturers.

System installation is handled by a Quantum certified installer, but may be done by the owner/user. The installer digs a small hole, approximately 6” in diameter and 12” deep, places the sensor at the bottom of the hole, and refills the hole, packing dirt tightly around the sensor. Unlike many traditional types of ground sensors, the sensor does not need to be accurately vertical, simplifying deployment. The node may be buried in a similar fashion, deployed on the ground surface, or mounted to a short post above the ground, depending on the nature of the installation.

The installation may be temporary or permanent. The deployments may be of a single seismic acoustic sensor-node-user-interface configuration or multiple sensor-node combinations supporting a single user interface. The installation may be at a single point or along or around an entire perimeter with a length of tens or hundreds of miles.

The Seismic Acoustic Sensor System is configured for detecting and classifying human footsteps, motor vehicles, and digging. Additional potential threats, such as motorboats and powered aircraft, are available as custom options. The standard software supplied with the product is installed on the customer monitoring device and displays coded icons at the sensor positions in map view. The icons show the state of health of each seismic acoustic sensor and the type of each potential threat source detected.

A SINGLE CHANNEL SYSTEM may be deployed with one sensor, one node, and one base station, as shown above, to provide 360º situational awareness. The base station and monitoring device are able to support multiple sensors and nodes, monitoring multiple sensor locations on a single user interface. Adding sensor-node combinations to the system generates the configuration as diagrammed to the right. The sensors and nodes may be deployed with their antennas within range of the base station antenna.
