Seismic Underground Detection system

The ultimate underground detection technology. A reliable solution for detection of underground intrusion or escape scenarios, including digging under the fence, approaching vehicles, heavy machinery at work, as well as any damage, cutting or shorting of the sensor line or cabling. 


The TERRA-SENS system is currently in use in variable applications ranging from border and critical infrastructure security to customised adaptive seismic systems for vehicle and ammunition depot protection. 

The TERRA-SENS uses proprietary seismic geophonic sensors buried underground along the fence perimeter, connected to local interface units deployed serially along the physical barrier. 

The system can be used in conjunction with other systems and connected into CCTV systems.
