Claim 6:
7. A non-transitory machine readable medium having information recorded thereon for detecting a target object via a security post, wherein the information, when read by the machine, causes the machine to perform:
receiving information from one or more sensors deployed on each of a plurality of sections of the security post, wherein the plurality of sections of the security post are arranged in a vertical direction and each of the sections is designated to detect the target object within a vertical range;
for each of the sections for a corresponding vertical range of the security post,
analyzing the information received from corresponding one or more sensors to extract features characterizing magnetic field variations sensed in the corresponding vertical range,
determining whether the target object is detected within the corresponding vertical range based on the extracted features, and
triggering, if the target object is detected, an alarm associated with the section to indicate a detection of the target object within the corresponding vertical range;

determining an overall detection result based on the detection from each of the plurality of sections;
displaying, on a display screen, the overall detection result and
determining, by detecting a signal from active electronic device that is turned on, whether the active electronic device that is turned on is present near the security post.
