Border Surveillance System Uses Satellites To Track Slight Vibrations

When Department of Homeland Security leaders released initial details last month about a massive upcoming procurement for border security technology, they expressed a clear preference for current rather than emerging devices.
However, the border surveillance technology of Airsis Inc. could make a case for classification in both categories. Several federal agencies — including the U.S. Border Patrol — are currently using its intrusion detection system (IDS), and officials for the San Diego-based firm say it is the only such system to use satellites.
Here’s how it works: its ground sensors capture vibrations of any animal, human or vehicle in its range, relay that information to a satellite — via a wireless uplink station — and transmit from the satellite to the operation center. The devices are so sensitive, they can tell the difference between an animal and a human by matching the vibrations against known seismic signatures, says Chief Technology Officer Jim Drewett. Drewett is at the center of the story of how the technology came to be.
