Radio Frequency Systems
Radio Frequency
(RF) Systems are the most widely used systems
in the United States today and RF tags and labels are
getting smaller all the time. As you can see in the
drawing at the right, the RF EAS system works like this:
A label -- basically a miniature, disposable
electronic circuit and antenna
-- attached to a product responds to a specific
frequency emitted by a transmitter antenna (usually one
pedestal of the entry/exit gate). The response from the
label is then picked up by an adjacent receiver antenna
(the other pedestal). This processes the label response
signal and will trigger an alarm when it matches
specific criteria. The distance between the two gates,
or pedestals, can be up to 80 inches wide. Operating
frequencies for RF systems generally range from 2 to 10
MHz (millions of cycles per second); this has become
standard in many countries. Most of the time, RF systems
use a frequency sweep technique in
order to deal with different label frequencies.
 
EAS Systems General InformationElectronic article surveillance (EAS) systems are used for inventory control and to prevent theft and similar unauthorized removal of articles from a controlled area. Electronic article surveillance systems allow the identification of a hard tag or soft label within a given detection area. EAS systems have many uses, but most often they are used as security systems for preventing shoplifting in stores or removal of property in office buildings. EAS systems come in many different forms and make use of a number of different technologies. The two most popular technologies on the market are Radio-Frequency and Acousto-Magnetic systems, which are both included in American Security's unique product range.
