Decoy package alarm for theft deterrence

A method of deterring package theft, comprising:

• placing a decoy package outwardly resembling a delivered shipping parcel at a delivery location;
• arming the decoy package;
• sensing motion of the decoy package using one or more motion sensors disposed within the decoy package;
• classifying, using a controller operatively coupled to the one or more motion sensors, the sensed motion to detect a removal attempt;
• and
• in response to detecting the removal attempt, activating an audible alarm operatively coupled to the controller to emit an acoustic output of at least 90 dBA measured at 1 meter after an activation delay of between 0.5 seconds and 3.0 seconds;
• wherein the removal attempt is a motion characteristic of lifting or carrying away the package.

A device for deterring package theft used with a shipping parcel, the device comprising:

• a housing;
• one or more motion sensors disposed within the housing;
• a controller operatively coupled to the one or more motion sensors;
• an audible alarm operatively coupled to the controller, wherein, when the device is in an armed state, the controller is configured to process and classify sensor data, including at least one of a tilt threshold and a vertical acceleration threshold, using sensor data to detect a removal attempt and, in response to detecting the removal attempt, activate the audible alarm to emit an acoustic output of at least 90 dBA measured at 1 meter after an activation delay of between 0.5 seconds and 3.0 seconds;
• and
• a mounting structure connected to the housing and configured to mount to the interior of the shipping parcel;
• wherein the removal attempt is a motion characteristic of lifting or carrying away the housing.
