The book anti-theft system is a self-defense device for books. It gives books a self-defense ability through electronic means, that is, once someone tries to take books out of the store without permission, it will notify the system and give an alarm. This fundamentally changed the passive state of all previous anti-theft systems in monitoring anti-theft, so that anti-theft measures can be implemented on every commodity.

The book anti-theft system consists of a detection door, a detector host, a charge-discharge sensor, a back detector and a magnetic stripe.

Detection gate: It consists of a sending gate, a receiving gate (single channel) or a sending gate and two receiving gates (dual channels). Its basic principle is that the transmitting antenna emits a scanning band and a scanning area is formed between the transmitting antenna and the receiving antenna. An effective magnetic stripe appears in this area, and the receiving antenna receives the signal, triggering the detector host to alarm.

Detector host: used in conjunction with the detector door to form a system.

Charger-desensitizer: used to magnetize or degauss the composite magnetic stripe in the book.

Recheck instrument: used to check whether the magnetic stripe in the book is in good condition.

2. Product introduction

1) technical features

Popular products designed for libraries, bookstores and video stores can detect various types of magnetic strips.

L adopt electromagnetic wave technology.

L adopt all-digital digital technology to minimize the occurrence of false positives.

L Adopting imported technology, the system is stable and reliable.

L beautiful appearance, high sensitivity and low false alarm rate.

2) Performance advantages

L product is composed of multiple integrated circuits, which is a real digital product.

L product is an optimized product of imported technology. In order to ensure the system performance, most of the internal components are imported components, which laid a good foundation for the long-term stability of future products.

L digital circuit, high monitoring accuracy, greatly reducing blind spots.

Low AC noise of digital products.

3. Management style

According to the way of use, it can be divided into two ways: human book diversion and human book non-diversion.

1) The mode of separating people from books.

People put books on the management desk, people pass through the middle of the monitoring channel and get books at the other end of the management desk. If this person has a book on him, the monitor will call the police when he goes out.

In this way, a permanent magnetic stripe can be used.

2) People and books are not separated.

A person gives the book to the administrator, who can go through the monitoring channel with the book after degaussing. If this person does not have a proper account book, he will call the police through the monitoring device.

This method must use a composite magnetic stripe.
