Trump’s Border Wall Could Be Invisible: Pathfinder could be the future of surveillance at the southern border.

Ground Sensor

soldier in Afghanistan kneels down, maybe to tie his shoe or set his gear on the ground for a moment. A minute later, he stands up and keeps walking. To the casual observer, nothing out of the ordinary just happened, but a closer look reveals that he just buried a coffee mug-size sensor in the dirt, one of several he will sink on this patrol.

The device, called an expendable unattended ground sensor (E-UGS), will automatically alert a workstation or mobile phone when a human walks within 30 meters of it. The UGS can act as an invisible trip wire, or a surreptitious doorbell, and can be linked to trigger cameras, drones, or remote-controlled weapons. The target would never know how he or she was discovered. It sounds like advanced combat, but in a few months, the person burying that sensor might not be a soldier, but a U.S. border patrol agent working on President-elect Donald Trump’s wall.
