ATG seismic unattended ground sensors (UGS) form part of our ATG All Terrain guards solution for monitoring and securing wide areas, remote assets and extended perimeters.

 The ATG seismic unattended ground sensor (UGS) system combines an innovative, rapid-deployment design, exceptional power efficiency and accurate target detection and classification with intelligent wireless networking. Our sensors will reliably detect and classify people and vehicles, filtering out false alarms, and can be easily integrated with remote cameras and wireless surveillance hubs to form a complete integrated surveillance solution for visual confirmation of targets.

Weighing less than 0.45kg and with an ingenious screw-in design for ease of use, our sensor nodes are portable, redeployable and designed to ensure optimal contact with the ground for exceptional seismic – sensing performance.

Our innovative power- efficient wireless platform also has the intelligence to adapt if one node is put out of action. The platform will simply self – heal. As part of an integrated surveillance platform, unattended ground sensors (UGS) can provide a cost – effective alternative to conventional measures, especially on sites where perimeters are in extreme locations or constantly changing.


ATG is flexible enough for use in Goverment and military applications – wherever conventional security measures are impractical. Its innovative design makes it ideally suited to covert applications:

Force protection and forward – operating base security Border – Port, Airport security

High – value asset protection (Oil and Gas, Pipeline, CNI, VIP) Temporary security or augmentation of fixed security


External sensors are added to increase detection capabilities and be used alongside existing internal sensors. These sensors classify and confirm targets that are within the sensor’s vicinity.When an intruder sets off the Sensor Node this connects with a Network Node which will relay an alarm signal to the Destination Node connected to a handheld device / PDA, or Mission Commander, notifying the team of any potential threat.

Designed as a small, quick-to-deploy sensor, ATG is able to protect wide areas and remote assets from unauthorised access, using superior detection algorithms which transmit alarms over its low power mesh network back to a master node from where users can be alerted. With long battery life and the option to add real – time video streaming on alarm, ATG has been proven in some of the world’s most hostile and demanding operational environments.


At its heart, ATG uses a seismic sensor to detect activity. The sensor is more robust and smaller than components traditionally used for unattended ground sensors. It is also less sensitive to the angle of tilt so does not require the sensor to be carefully aligned when deployed and it is more immune to external electromagnetic fields. ATG can detect intrusion of personnel at distances between 40 and 100 metres, depending upon the ground type.


ATG’s standard algorithms can reliably detect and distinguish between people and vehicles. Based on advanced single-processing techniques and exhaustive testing under many different environmental conditions, ATG’s algorithms have been tuned to provide accurate alarming and classification. A number of more specialist detection algorihms are available on request.


A principle design consideration for ATG (recycle usage) was battery duration of around 24 months from a single D cell-sized battery. But the disposable applications battery life extend to 60 months (with micro solar back-up). This performance is independent of the rate of detections and provides the optimal balance between size and weight of node from a deployment perspective and revisit rate. Cityline connected and chargable battery supply types are optional.


ATG’s low profile, auger-shaped design has been optimised for maximum seismic transmission and includes an integral aerial, meaning no external antenna is needed. This means ATG is capable of being completely buried, providing a solution when coupled with its stealthy mesh-transmission profile, that is capable of highly covert operation.


Designed to be light, small, rugged and quick to deploy, ATG’s unique auger design with installation tools get sensors into the ground quickly and efficiently with no digging. Specialist deployment aids are also provided to allow geolocation of nodes and rapid diagnostic of mesh signal strength and ground conditions for optimal usage.


ATG includes mesh-only nodes that allow third-party sensors, such as passive infrared-PIR’s, ultrasound or magnetic anomaly, to be included in the sensor field. This provides maximum flexibility to utilise the right mix of sensors for each deployment within a common environment.


ATG’s seismic-sensing algorithms have been extensively tested and tuned to provide class-leading false-alarm rates. Alarm rules operating across the sensor network can be applied to reduce false-alarm rates to near zero for many applications.


ATG has been designed to work closely with, TRANSVARO-Soft Horizon real-time wireless video technology. The tightly integrated capability means that ATG sensor nodes can be used to trigger video surveillance cameras to provide users with real-time visual confirmation of alarms.
