A system may include a security controller communicatively coupled with pedestals having a first set of antennas and a second set of antennas spaced from the first set of antennas to form an interrogation zone. The security controller may be configured to alternate transmission and reception of interrogation signals between the first set of antennas and the second set of antennas. The security controller may be configured to determine whether a metal object is detected in the interrogation zone in response to the reception of the interrogation signals by the second set of antennas or by the first set of antennas. The security controller may be configured to generate and send an alarm signal in response to the metal object being detected in the interrogation zone.
A security system, comprising:
A method of controlling a security system comprising a plurality of pedestals with a first set of antennas and a second set of antennas spaced from the first set of antennas to form an interrogation zone, the method comprising:
A computer-readable medium storing computer executable instructions of controlling a security system, comprising instructions to:
