Sound and magnetic alarm mechanism and type of anti-theft device

The sound and magnetic anti-theft device uses the principle of the tuning fork to generate resonance through the vibration of the sound and emit an alarm sound. The radio-frequency anti-theft device uses a low-frequency electronic signal to send out an alarm by transmitting and receiving electronic signals. But in the actual use of these two technologies, we discovered that acoustic and magnetic alarms performed much better, not only in terms of theft distance, anti-interference, or false alarm rate, but also stronger than radio-frequency anti-theft devices. The product cost of the anti-theft device is also much higher, which is also the direct reason why the sound and magnetic anti-theft device is expensive.
High-end clothing stores should use sound and magnetic anti-theft devices, mainly due to the value of goods, high-end clothing stores are generally more expensive clothing, stolen situations will be a big loss. The use of radio frequency systems, in the anti-theft performance is worse, can not fully protect the safety of clothing, in the detection of distance, false positive rate should be higher, which is easy to bring unsafe clothing products.
After years of experience in the industry, our company's security door products have gained a good reputation. The supermarket clothing store's anti-theft brand has also emerged as the best in the industry. The products are widely used in supermarkets, shopping malls, clothing chain stores, cosmetics stores, The library, school library and other places have received a consistent good reputation and have become high-quality anti-theft brands.
1, RFID system (full name: radio frequency identification system; low frequency 125K, high frequency 13.46M UHF: 900MH)
2, AM system (full name: acoustic and magnetic goods anti-theft system frequency: 58KHz)
3, RF system (full name: radio frequency system frequency: 8.2MHz and individual others)
4, EM system (full name: electromagnetic anti-theft system frequency: 1-2MHz)
Different systems have different functions and use environments, usually EM systems are used for library books, AM and RF systems are suitable for supermarkets, clothing stores, etc.
