Sentinel Technology



WG’s Sentinel protection technology, is the most robust product protection and inventory tracking system on the market today without the use of pedestals. Sentinel is designed to manage all protected merchandise within a specified area. Using WG’s sophisticated technology Sentinel tags communicate with overhead readers, protected products can move freely within the detection range. The Sentinel system will alarm only if the tags are tampered with, illicitly removed, or if the tags exit the protected area.


Sentinel works as a discreet stand-alone system or can work in conjunction with your current EAS system as an added level of protective. Sentinel comes with software that monitors each tag individually. This allows for stockroom, dressing room and other sensitive areas to be monitored. Sentinel can prevent any type of merchandise from leaving the area of protection, the possibilities are endless.

Sentinel Components

A critical component of the Sentinel system are the readers, or 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 zone of protection to ensure free product movement within the protected area without false alarms. There are three types of RADs, each perform a vital function for the system to work: The RFID RAD, which constantly searches and communicates with each tag, the EAS RAD

causes a tag to alarm if the tag is taken beyond the protected area and the POS RAD,  deactivates a tag when the protected merchandise is purchased. Working together the Sentinel RADs provide an impressive level of effective protection.

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.

Sentinel Tags

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.
