The loss of the goods has undoubtedly increased the burden on enterprises, to this end, the burglar alarm industry applications.
Loss prevention gradually as the leader of domestic enterprises. Here to introduce 7 new shopping centre, electronic anti-theft alarm technology types.(1) sound magnetic system
Tuning fork only in the oscillation frequency is the same as the circumstances causing resonance.
Acousto-magnetic system (Acusto Magnetic) is the application of this principle, achieving almost physics with zero false positives, fixed merchandise sound magnetic system labels into the system of detection area, produces resonance, but only in the receiver receives fourth consecutive by resonance signal (every 1/50 seconds), it emits a beep.Acoustic characteristics of the magnetic system is an intrusion detection rate is high, nearly zero false positives, immunity, protect's exports width up to 3. 5 m, there are two kinds of hardware and software, on the Mall anti-theft tag most types of goods can be protected, and can repeat degaussing, even in the POS cash drawer side system is still functioning.
Sound magnetic system including the vertical system, channel type system and covert system of different kinds, more than 10 kinds of models to choose from, can be widely used in department stores, supermarkets, stores, video stores, grocery stores, drug stores, also available in the Office building and the environment.
(2) radio system
Radio systems (Radio Frequency, RF) using radio waves as the emission of the signal received, the detection in the frequency range of the electromagnetic wave 8.8MHz 7.4-, center frequency is caused by the label 8.2MHz in 8.5MHz interference, thereby triggering the alert.
The biggest advantage of radio system is a system cost is very low, easy to install. However, due to its anti-theft tag for the loop type, so the system vulnerable to interference of some items, such as cash drawer, and other electronic products, metal, etc., caused by a system of false positive or not.Radio system with soft and hard two labels, you can protect most of the items in the shopping centre.
Two bearing distance between generally cannot be greater than 0. 9 m, usually used in only one import and export of shopping malls. Radio system with vertical and channel-both for the protection of the Department stores, clothing stores, supermarkets, etc.(3) the electromagnetic systems
Electromagnetic wave systems (Electromagnetic System) using electromagnetic waves as the heartbeat.
Electromagnetic wave system label smallest, label the price is cheap, can duplicate the degauss, but vulnerable to magnetic or metallic substances in which produce false positives. Protection of width is generally 0. 9 meters. The system will not be on magnetic materials (such as audio and video tapes, magnetic card).The new generation of channel-type electromagnetic systems is a software-controlled electronic anti-theft system, using a digital processing techniques and degaussing systems, cash register monitoring, closed circuit television monitoring system integration.
Use the quick degaussing plate, can duplicate the degauss, system cost. Electromagnetic systems have vertical and channel two. Application environment more in libraries, bookstores, music stores, hotels, supermarkets, etc.(4) microwave systems
Microwave systems (Microwave System) using microwave as heartbeat, insensitive to ambient interference, its flexibility to covert installation (such as hidden under the carpet or hanging on the ceiling), suitable for shop decorative and attractive benefits.
But because of the large range of the receptacle shall, in a certain region cannot arrange merchandise, this gold to the inch, the businessmen will limit the use of space, therefore suitable for large department stores and store larger music shops, boutiques.(5) frequency system
Frequency-division system (SplitFrequency) is made of high-tech low frequency radio frequency technology and signal security system.
When a detection zone anti-theft tag entry, label receives a launcher passes signal, and put it into half, and then has been divided into half of the information transmitted to the receiver, the receiver has received only half a signal when a beep, can effectively avoid interference from other radio waves. The system label light, small, cheap, stable performance, high rate of detection, anti-jammings well, does not cause false positives. Products are vertical and subtle type two, is a fashion shop more ideal anti-theft system.(6) the intelligent system
Intelligent systems application unique technology, is an internally by IC control, battery-driven, set hard tags and alarm group as one of the system.
When the label was prized or with the goods being brought out shopping centre, the system will automatically alarm. The system can make the entire Mall-wide goods are protected, accurate report, tags can be reused, without damage of goods. Used to protect valuables, such as fashion, leather, fur coat, etc.(7) the principle of system failure
Undermine the principle of the anti-theft system is a hard tags or magnetic locks.
Hard tag contains ink, when the thief trying to dismantle this hard tag, hard tags will emit ink, contaminated goods and thieves. Magnetic lock very easily dismantled, forcibly removed will destroy the goods, it is easy to use, has a very good deterrent effect, and the cost is very low, in clothing, glasses, jewelry, ties, silks and other goods, labels can be reused.
