Makeup Markets Anti-thief System Project


A. Introduction of anti-thief system

The technical principles of the EM anti-thief system:


1. EM anti-thief system

The basic principle is to detect if the objects have the EM strips by the transformations of the alternating magnetic field to prevent thefts. The electromagnetic identify technology is chief technology.

The electromagnetic technique detects by the alternating magnetic field produced by the low frequency from 10Hz to the 20 KHz of the detecting antennae (transmitting antenna & receiving antenna). It detects the EM strips of the objects. The strips are PoMo alloy soft strips with cragged hysteresis loop . The polarities of the strips will be magnetized periodically over and over again when they were inside the alternating magnetic field of the transmitting antenna. The magnetic flux density B of the strips changes jumpily near the place where the external magnetic intensity H spans 0 (non-linear characteristic), then the harmonic wave would be produced whose frequency is the baseband of the transmitting antenna, and the receiving antenna will receive and process the wave and produce the alarm signal.

The system has many obvious advantages. First of all, it is the only one system to detect the objects that have metals or foils inside, the market could largely expand the protecting scope with the system. Secondly, the material cost ( strips ) is lower than RF soft label, the system will save a lot of money in a long time for makeup markets.

2. Anti-thief principles of RF system:

The working principles of RF system: the transmitting and receiving antennae uninterruptedly transmit and receive electromagnetic waves between 7.4~8.8 MHz, the interferences with 8.2 MHz center frequency caused by labels will cause the alarm.

To help you understand the strongpoints and defects of our system clearly and help you make a wise decision, we will compare EM system with RF system by a form:

The working principle flow of the library alarm system-

1. Set the EM strips inside the goods.

2. Set the detectors at the exit channels.

3. Degauss the goods by the special deactivator after the normal checking.

4. The goods without normal checking (that have the strips inside) will make the door detectors alarm and stop the customers.


 The function of the EM alarm system

1. Preventing thefts. The system changed the old ways that the workers have to gaze at the customers or the workers have to take good care of the books in case that someone would steal them. The system makes each of the books protects themselves and solves the stealing problem totally. That would reduce the loss of bookstores.

2. Simplify management. The system could effectively prevent inner thieves, ease contradictions between managers and staff, exclude the staff's psychological barriers and let them work absorbedly and increase working efficiency. Also the system could reduce employees and optimize employees at the original basics to save operating costs and improve service level.

3. Alarm. The system could stop the customers stealing with a tough and polite way. It could avoid the disputes between persons and it could protect the profit of the bookstores, meanwhile respecting the human rights. The system could warn and stop the thieves psychologically.

4. Improve the borrowing atmosphere. Many people hate the old gazing way. The system could create a better atmosphere that customers could select books freely, and it could improve the relationship between the merchants and the customers which makes the circumstance more comfortable and help the merchants to attract more customers.

5. Beautify the circumstance. The system is a high-tech and pretty product, it could beautify the circumstance when protecting the books. The system is a new trend for the bookstores.


The makeup anti-thief system project and cost

A. Separate the persons and goods:



 I. Set the detectors at the cashiers;

I I. Set the EM strips on the goods that need protecting;

I I I. This way let persons and goods pass by different channels. Customers pass by the detecting channel and goods pass by cashiers and the goods won't pass the detecting host directly and will be passed to the customers by the cashiers. In this way you needn't to buy deactivator. The strips will be degaussed forever and it will reduce your costs with the same anti-thief function. ( Defects : the cost of the whole equipments will be a little higher relatively and the cashier location may limit the setting. Strongpoints: avoid the contradictions between merchants and customers caused by the system alarm because the books are not enough degaussed, create a more comfortable shopping atmosphere.) It will be necessary for makeup shops to set the EM strip check equipment.

B. Protecting modes in exits:


? . Set detectors at the main exits;

? . Set deactivator on the cashier tables;

? . Set the EM strips on the goods that need protecting;

? . If the bookstore separates the entrances and exits then they just need to set detectors at the exits. It could reduce the number of the equipments and save investing costs. ( Defects: higher requirement on cashiers, if books aren't degaussed enough that may cause contradiction between workers and customers, the necessary strips are composite strips that can be magnetized or degaussed and they are more expensive than permanent strips. Strongpoints : the total costs for equipments are lower and the location will not impact the setting generally.)

Notes: the distance of single channel is 75~100cm and the total distance of double channels is 150~200cm.

EM Deactivator/Reactivator

This machine is matched just for the composite strips. It could only be useful when using composite strips.

It is the first decoding machine with infrared ray opposite sending technology in China . It only works when objects being decoded in the degaussing status, which could prolong the using time efficiently.


The EM strips:


According to the sorts we have cobalt strips and iron strips.

According to the functions we have permanent strips and composite strips.

1. Permanent strips that couldn't be magnetized or degaussed.

The magnetism of the strips exists forever and they couldn't be decoded. They are cheaper. They have high alarm rates and they could be hided easily. And we also have the double-sided adhesive strips that make the operation easier.

2. Composite strips that could be magnetized or degaussed.

They could be decoded but have a little higher price than permanent ones. And we also have the double adhesive strips that make the operation easier. Length: 40, 50, 60, 80, 100, 120, 160 (mm).

According to the appearance we have permanent naked strips, adhesive strips and barcode adhesive strips.

Wireless Deactivator :


It is made from special materials. It doesn't need electric power. It can be used in any circumstances and it has a long life. It has a high degaussing intensity and could degauss many books at the same time.
