ALL TYPES OF ANTI-THEFT SYSTEM
You will surely have happened to pass or see pass through the doors of a shop and set off the anti-theft system alarm, with unspeakable embarrassment. This is normally due to these tags that we find on clothes that are "heard" by the antennas placed at the end of the doors at the exit of the shops.
But how does the anti-theft system work? How do the sensors feel the presence of these small, perhaps hidden, tags? And why the sensors can trigger carrying objects from the outside?
There are three types of anti-theft systems based on the use of bars and adhesives, distinguished according to the principle of operation. Each type of plant has technical characteristics that make it more suitable for one type of activity than the others.
CONCLUSIONS
These systems are particularly
effective in deterring thefts within stores, even if thefts of all kinds
continue to occur in one way or another. Sometimes the question arises as to
why the anti-theft sensors are so evident at the entrance of a shop: in fact
they could also be hidden without great additional costs, but the main reason
is the deterrence to carry out thefts, a bit like the sign "beware to the
dog ”or the fake surveillance cameras. In these systems, false alarms
occasionally occur, for example due to metal objects that can cause a signal
that is confused with that of a nameplate. Or it may happen that a shop does
not demagnetize a tag sufficiently, which makes it active in a shop with
sensors set to more sensitive parameters. That said, all that remains is to
wish you good shoplifting
