A computer-implemented method includes receiving, by a base station of a security system, an identification of a shipment package, the identification received from a first security sensor that is part of the security system. The method further includes adding, by the base station, a shipment device of the shipment package as a second security sensor of the security system. The method further includes configuring, by the base station, the shipment device in protect-mode, wherein the shipment device sounds an alarm in response to the shipment being displaced by at least a predetermined distance when in the protect-mode. The method further includes reconfiguring, by the base station, the shipment device in safe-mode in response to receiving, from a customer associated with the shipment package, a confirmation signal that the shipment package has been safely received.
