Abstract
Methods and a device for detecting physical intrusion are providing, the device including a vibration sensor, a processor, a transmitter, a battery, and a conductive wire connecting the vibration sensor and the processor. The vibration sensor is affixed to a first part of the device, and the processor, transmitter, and battery are affixed to a second part of the device. The first and second parts, when attached together, form a case containing the conductive wire. The device performs steps of: sampling a set of seismic signals from the vibration sensor, determining that the set of seismic signals matches a seismic threat pattern, and responsively issuing an intrusion alert.
