Metal Guard/ Metal Spy/ Metal Wall PCB
the system is designed to detect moving metal objects to alert shop security or personnel of potential professional shoplifters who may be using foil-lined "booster bags" to shield RF or AM tags and labels so that they are not detected by the EAS system.
Sitting adjacent to any existing tagging system and linked to a remote alarm pager and/or CCTV system any unusual large metal objects passing through the system will trigger the alarm, however as there is no indication of this at the barriers themselves any potential thief will be unaware as to whether the system has detected them or not . There is also a very powerful, proven visual deterrent effect, stopping many potential thieves from even attempting to enter a store.
