How does a book EAS EM anti-theft device work?
Many people who go to the library to borrow or return books will see the librarian swiping a few times on one device. Why is this operation carried out? In fact, it is because when borrowing books, the administrator needs to demagnetize the magnetic strips inside the books, and when returning books, the magnetic strips need to be remagnetized.
The EAS EM book anti-theft system includes EM electromagnetic wave anti-theft devices, anti-theft magnetic strips and demagnetizers.
EM electromagnetic wave book anti-theft Device: An electronic anti-theft device commonly found in major reading rooms and bookstores, it features high alarm sensitivity and wide application. It is equivalent to an anti-theft detector. When the magnetic strip passes through the anti-theft device without demagnetization, an alarm sound will be emitted.
Anti-theft magnetic strips: Magnetic strips are usually deeply embedded in books. When borrowing or returning books, demagnetization and magnetization actions are required.
Magnetization and demagnetization device: Magnetizing the magnetic strip gives it a "detection" signal, while demagnetization makes the detection signal disappear.
Since the magnetic strips that come with the EM electromagnetic wave book anti-theft device are made of metal, we must try our best to avoid the influence of metal shielding during the installation process. Otherwise, false alarms and missed alarms may occur. During the on-site installation process, it is necessary to find a more suitable installation environment for the EM electromagnetic wave book anti-theft device so that it can achieve a better anti-theft effect.
In conclusion, the EM electromagnetic wave book anti-theft device is a highly reliable and user-friendly anti-theft equipment for books. After more than a decade of product iteration and technological upgrades, the EM electromagnetic wave book anti-theft device from ABNMTECH can well meet the anti-theft needs of different customers. It features a high degree of intelligence, simple installation and debugging, and other characteristics.
