EAS System / antitheft system

Electronic article surveillance (EAS) is a technological method for preventing shoplifting from retail stores or pilferage of books from libraries. Special tags are fixed to merchandise or books. These tags are removed or deactivated by the clerks when the item is properly bought or checked out. At the exits of the store, a detection system sounds an alarm or otherwise alerts the staff when it senses active tags. For high-value goods that are to be manipulated by the patrons, wired alarm clips may be used instead of tags.

EAS Gate
Promatic PDS3210 Electronic Article Surveillance System is designed and manufactured by a team of highly trained electronic engineers in the field of security engineering. The system uses the Radio Frequency technology to tags all merchandise thus allow the merchant with the ability to prevent unpaid item from leaving the store without notice. The PSD3210 while prevent commodities from being stolen effective at the same time it can help to built relationship between customers and store owner. This system is designed to suits all kinds of retail sites, such as supermarkets, AV stores, clothing stores, bookstores, library, drug stores, game arcade and any establishment that have an open shelf business concept etc. This system can also be used to tags on elderly in homes and children in child care centre. The Securitex/Promatic EAS system was manufactured under the ISO9000 standard and carries the CE certification as well.

The PDS3210 system c/w the following advantages:

- High sensitivity and very low false alarm rate as the system adopted the 2nd generation DSP (Digital Signal Processor) technology.
- Anti-disturbance from metal handcart, hand’s touch and it can also be installed on gate with metal baffle
- It adopts filter technology and decrease noise circuit technology.
- Two kinds of alarm tone---quick and slow, it also has three kinds of volume---high, medium and low for you to choose according to your needs and the environment noise level.
- It is also very convenient to install and calibrate.
- Performance is unique and novelty. The design is very pleasing to the surrounding as the unit is manufactured from metal structure thus it is very rugged, reliable and highly durable.

How does EAS work.

Electronic Article Surveillance system (EAS) is a kind of electronic anti-shoplifting system that can decrease shoplifting when retail enterprise implement open-shelf sale this in-return increase sales and profit. EAS system consists of electronic sensors (transmitter and receiver), deactivator system and label or tag. Electronic sensor that are located at store exit and entrance transmitter (TX) will send a unique RF signal at certain frequencies to a receiver (RX) which creates a "RF surveillance zone" around the store exit/entrance. When a product with an active label or hard tag is moved past a this sensor surveillance area, the sensor will detect this tags and sets off an alarm. Radio Frequency (RF) is the most popular and common technology in today EAS system, it adopts Radio Frequency as Transmit and Receive signal, the detection frequency ranges from 7.x~8.xMHz. The advantage of RF EAS system is cost effective.

Intelligent Digital Identification Technology.

EAS Deactifator
PDS3210 series of digital RF sensor using AD transform technology sampling the simulative signal high-speed, prosecuting computerized signal intelligent identification (CSDM) label under noisy background. It is different from the simple parametric technology that it only identifies the spectrum and the functionary periods of label signal. At the same time, it increase filter and decrease noise circuit in these new technology compared with traditional EAS system. With this new technology implemented in PDS3210 sensors it increase the sensitivity but prevent low and false alarm at the same time.

Securitex/Promatic PDS3210-EC can also be use in the field of human movement monitoring application. In serve cases of senile dementia patients, normally they will wonders of the premises without the staff and doctors noticing them. At Securitex our system will be able to alert the respective doctors, nurses or caregivers when this patients wonder of the premises. The system will be able to sent out a signal to the caregivers and corrective action can be taken before this patient wonders off and get lost.

Securitex/Promatic PDS3210-CC can also be use in the child care centre to monitor the movement of the children within the centre. Many time children get lost when they wonder off the premises without the teachers and attendance noticing them. At Securitex our system will be able to alert the respective centers attendance when this children play nears the doors or when strangers try to bring the child out of the centre . The system will be able to sent out a signal to the caregivers and corrective action can be taken before this child wonders off and get lost.
