New seismic unattended small size module for footstep detection

Abstract

General Sensing Systems (GSS) has achieved outstanding and verifiable results in the design and performance of seismic systems with near zero false alarm rates for the detection of walking, running, and jumping persons. These results have been reported in various homeland security and military applications. GSS has been developing a new seismic, unattended small size module for footstep detection. This paper describes our design for the module, which includes the two-board and one-board versions-fitting into various consumer applications. Communication interface versions, which are used in the detection module, allow the communication with any wireless surveillance network. We also report on the preliminary lab and field-testing that was implemented in various conditions. We show that the new unattended, small size detection module demonstrates the same reliable performance as our previous full size systems.

Field testing of new unattended small size seismic module for various target detection

“…The full set of the hardware for working in the field is shown in Figure 3 below. The software preloaded in the described seismic detection module has the same architecture as was described in our paper [6] for the first generation of the detection module. The detection capabilities are at the same high level, but the average power consumption of the last generation detector is much lower and actually does not exceed 15mW for a reasonable number of targets in the detection area.…”

“…The redesigned detection algorithm also helps to efficiently improve the performance of the small-size, unattended seismic detector in terms of the detection capability of various target classes. In the future, the use of the GSS miniature sensor [6][7][8][9][10] can additionally improve the unattended seismic detector performance capabilities and characteristics.…”
