Sentinel is a groundbreaking new security concept for reteil applications. Unlike traditional EAS-Systems, where the systems are installed at the exit as a "barrier for shoplifters, Sentinel monitors of the entire sales area.

Several "Field RAD" antennas transmit information to the Sentinel tags on the sales floor. As long as the tags receive these sentinel signals, everything is fine. If the signal is shielded or jammed (i.e. by a shoplifter), the tag recognizes this and alarms. An amplifier or a Seninel "EAS RAD" can receive tag alarms and add an even louder audiovisual alarm or trigger a CCTV or pager system. 

Open entrances without pedestals are a clear benefit of Sentinel active RFID systems. The system technology even allows to direct thefield radiation to an area. - Juas tas you need. 

The augmented security algorithm of the Sentinel tags supports the sales staff. If a customer enters the "Alarm Zone" the tag starts alarming. When the customer decides to stop and walk back into the store, the tag stops alarming auttomatically. 

The user has the choice to use the RFID features for merchandise security and logistic processes.

Sentinel ´s intelligent signal processing in tag and central unit make it

the first 6-alarm system in the market:

1) EAS-RAD alarms when unpaid goods leave the store
2) Tag alarms when unpaid goods leave the business
3) Tag alarms at tag manipulation / tampering (cutting, etc.)
4) Tag alarms when unauthorized detacher is used
5) Tag alarms when beeing shielded or signal gets jammed. 
6) Tag alarms when the monitored zone is left.


Sentinel Components

The main component of the Sentinel system are the Sentinel Readers, called RADs (Radiate And Detect). All RADs communicate wirelessly, making installation extremely simple. The RADs are placed throughout the store's ceiling to create a large secured perimeter zone to ensure free product movement within the store. There are three types of RADs, which each perform a vital function for the system to work:

Field RAD

These RADs radiate specific areas, emitting a signal from the ceiling in a 120 degree cone, which expands as it approaches the sales floor. A minimal amount of Field RADs can secure entire floors of products, or secure delicate or high-risk items within only a certain area of your store. This signal creates protection zones and searches for unauthorized tag presence. There is constant communication between tag and RAD. The system remains quiet as long as there is no disruption. Once signal disruption occurs, either by unauthorized detachment of the tag, tampering with the tag, or the tag leaving the area, the system will alarm.


At the point-of-sale, these RADs function as a deactivator and detacher; arming and disarming the Sentinel tags, allowing for authorized removal of the tag without causing alarms. Tags are armed by this device and then ready to be applied to merchandise on the sales floor. When the merchandise is purchased, it disarms the tag and allows for removal.


The EAS RAD is installed at the exit of the store. This particular RAD is the alarming RAD, notifying store personnel when a tag is leaving the area. It also triggers the tag itself to self-alarm when it passes by the EAS RAD detection zone, ensuring complete security.


The Sentinel Tags are sophisticated devices which perform multiple functions. Each tag is engineered to "listen" to signals emitted from the RADs. Constant communication between tag and RAD ensures the alarm remains silent. The tag is designed to self-alarm at any point of signal disruption, be it tampering, not being disarmed prior to removal from the merchandise, or removal from the protected zone. When tags enter into an alarm state, they will also notify the EAS RAD to audibly alarm. Since the tag is in constant communication, if it is removed accidentally from the protected zone, once it is brought back into the zone, alarming will cease since the signal is regained. Sentinel Tags come in lanyard form, but any size or shape tag can be made into a Sentinel Tag, depending on your store's needs.
