Patented signal processing algorithms and complex mathematical models, are implemented in the systems, which classifies the threat based on its seismic and acoustic parameters. The classification enables distinction between different threats, such as vehicle approaching, human movement, digging, drilling and more.
After Installation, the system is operating 24/7 in all weather conditions. The system is constantly charged and is constantly collecting seismic and acoustic information from the surrounding. With the signal reception, it is analyzed and characterized by mathematical functions. In the case of a suspicious activity, the system focuses on the suspected zone in order to eliminate background noises and amplifying sensitivity. For a more certain verification, the signal is now, transferred to a secondary analyzing procedure conducted by various mathematical and statistical functions designated to verify or reject the warning. In case of verification, the information is transferred to a procedure to determine the event's location. After analyzing, the system reports to the command and control centre to monitor the event.

The data processor can identify various activities such as:
a. Digging.
b. Walking.
c. Vehicle.
d. Electrical tools (drill, etc.)
|
|
The system is able to determine the event's location, filter noises and eliminate false alarms, operationally, can tell the treat distance from the target and determine operation modus.
