What is a multi-zone walk through metal detector?

Walk through metal detectors are very common nowadays since they can be found at schools, malls, government buildings, universities, airports, private buildings, sports arenas and other locations. These metal detectors come in two types: multi zone and single zone walk through metal detectors. A single zone walk through metal detector helps to identify whether an individual walking through the machine’s opening is carrying an illegal, harmful or unwanted item. A multi zone walk through metal detector helps to identify the exact location where a concealed item is located. This metal detector will essentially identify whether the item is on the left or right side of an individual.
Multi zone walk through metal detectors are the best for controlling larger crowds. These metal detectors can eliminate the possibilities of security personnel to have to perform physical pat down of all people that pass through the opening. Security personnel can even ease their work by using handled metal detectors. On the other hand, a single zone walk through metal detector can be used in an area where the security situation is under control due to the few people accessing an establishment. Whether multi zone or single zone metal detector, the location where the machine will be placed will generally affect the decision on the type of walk through metal detector an establishment needs to buy.
