How Do EAS Shoplift Prevention Systems Work?

Tuesday, April 3rd, 2012

Ketec EAS Shoplift Prevention SystemHave you ever walking into or out of a store and noticed that you were walking between a pair of gates? Have you ever noticed those gates beep or start flashing when someone leaves, either stopping them dead in their tracks or causing them to bolt as if a dog were chasing them? These gates are what’s commonly referred to as a shoplift prevention system (found here), sometimes called an electronic article surveillance (EAS) system. These gates are a must-have item if you sell “hot” items. So how do they work?

Retail stores lose literally billions of dollars a year to stolen and shoplifted merchandise. Many thieves have gotten really good at tucking music, movies, clothing and other goods away, making them almost impossible to detect by the naked eye. While security cameras do play a good role in detecting shoplifting, an electric article surveillance system is a critical companion that is needed in most stores.

EAS Shoplift Prevention Hard TagsValuable merchandise can be tagged with a hard tag or a soft tag (label / sticker). These tags send or reflect a signal that is detected by EAS shoplift prevention gates. In many cases, this is done via a radio frequency (RF) system. These gates send out and receive signals. This is usually based on a specific frequency. In the case of Ketec EAS systems, these signals are 8.2MHz, 9.5MHz and 10.0Mhz. As the gate communicates with hard tags and labels, it can tell if those tags have been properly deactivated or detached. If they have not been removed (hard tags) or deactivated (soft labels), the gate will produce either an audible or visual (often both) alarm. Not all hard tag systems will work with soft labels, however, most modern systems are compatible with both.

These gates usually consist of a transmitter antenna and a receiver antenna (hence the term gate). This isn’t always the case as some single tower systems do exit that contain both a transmitter and a receiver. The effective range of these towers is typically 5-6 feet, although this may vary from hard tag to soft label.

Ketec RF Deactivator for EAS Shoplift Prevention SystemsCommon Questions:

Can a shoplift EAS system be concealed? Unfortunately these gates cannot be concealed, however, many of them have either been designed to blend in or they have been build with transparent or clear materials to make them as inconspicuous as possible.

Can any tag or label be used with any EAS system? A lot of it depends on the frequency used. Most Ketec EAS shoplift systems will work with most labels and tags, however, I recommend checking the manual or speaking with a expert to verify compatibility.

Can anyone install an EAS system? Some EAS systems are complex and require an expert to set them up, however, most Ketec systems are as easy as plugging them in and arranging the towers.

What if the entryway is wider than the EAS system’s range? Many EAS systems can be configured and set up with multiple towers to expand the detection range.
