Claim 12:
13. A security post, comprising:
a base;
an overall alarm; and
a plurality of sections arranged in a vertical direction between the base and the overall alarm, each of the plurality of sections being designated to detect the target object within a corresponding vertical range; and
a signal integration unit configured for integrating the detection results from the plurality of sections to derive an overall detection result, wherein
each of the sections comprises:
one or more sensors configured for sensing information related to magnetic field in the corresponding vertical range,
a signal processing unit configured for analyzing the information to extract features characterizing magnetic field variations sensed by the one or more sensors, determining whether the target object is detected within the corresponding vertical range based on the extracted features, and determining, by detecting a signal from an active electronic device that is turned on, whether the active electronic device that is turned on is present near the security post, and
a section alarm configured to be triggered when the target object is detected.
