For anybody not a secret that today almost everybody wants to have their own business that will bring good profit. As a rule, now many open outlets. But in order to be developed successfully, they need to fill high-quality and original goods. In addition, you need to consider the protection of the products for sale.

Most of the modern retail outlets today will not be able to function normally without the use of security systems. Many anti-theft protection system today operate automatically and not require constant monitoring. There are several types of EAS systems.

The Most widely following types:

  • RF;
  • Electromagnetic;
  • Acoustomagnetic.

The Most technically advanced anti-theft system is safe to call the device the acoustomagnetic type. However, the widespread proliferation of such systems prevents their too high price.

The History

acoustomagnetic antitheft systemUsually, as the date of occurrence of the acoustomagnetic technology is referred to 1988. The development is owned by the company Sensormatic. The patent was issued in limited time. Today it is believed that the period of validity has expired. Now on the basis of the acoustomagnetic technology, anyone can easily produce their own anti-theft device. Sensormatic is currently the world leader in the development of anti-theft systems. Samples belonging to the acoustomagnetic type, convenient to use at retail outlets, specializing in sales of small goods.

Hardware

The Acoustomagnetic anti-theft systems typically have three major components.

  1. The Gate – the rack, the height of which can reach approximately 1.5 meters. These units also serve as antennas for generating and receiving electromagnetic waves in the range of 58 KHz.
  2. The Transponders (labels) – small articles, which represent a body of plastic material with special metal part – magnetic-acoustic resonator. Labels usually have small dimensions, which enables to install them on goods, not obscuring at the same brand image and information labels. Hackers tried to remove the label, it is disguised under the barcode. By themselves, labels are disposable devices. After selling the product, they are stored on the package. Another kind of transponders are tags. They perform the same tasks as the labels can only be used a few times. At the checkout such sensors are deactivated and removed from the packaging. The structure of the tags includes a block with magnetic-acoustic resonator and the shell in different designs. Another type of protective device is Boxing. The product is small size just fits inside. For fastening of labels on the bottles by the neck girth is used.
  3. The Fetters sensor – the equipment used for non-contact demagnetization of the tag or label. The working principle of this product is that it affects active transponder an alternating magnetic field. Devices of this type can be embedded in the equipment to scan a bar code. Thus, the seller can simultaneously be put in the database information about the purchase and deactivate the label.

To remove tags from the traded goods are used such devices as pullers. They are usually installed near the employee's workplace at the checkout. To prevent unauthorized use, some models are equipped with special lock, which locks the device in the absence of the cashier. For these purposes, a mobile hand-fetters.

Principle of operation

installing anti-theft systemsThe Acoustomagnetic technology uses the principle of the phenomenon of magnetostriction. It means the ability of some alloys to change their sizes under the action of a magnetic field. If the oscillation frequency of Ferroalloy resonates with the frequency of the oscillating magnetic field, their amplitude will become larger. The composition of the ferromagnetic alloy in modern transponders is selected so that it has a large value of magnetization. The strip of alloy under pulsed exposure starts to vibrate, thereby generating their own electromagnetic field. It captured sensitive component of the EAS system. To deactivate the label, transponder, need a long time to work on the strips with the alternating magnetic field and gradually reducing the power. This will cause misalignment resonant frequency Ferroalloy strips. On the field generated by the antitheft gate, the transponder will not respond.

The advantages and Disadvantages of acoustomagnetic systems

acoustomagnetic anti-theft systems for shopsThe advantages of acoustomagnetic systems include:

  • High reliability actuation (>95 %);
  • The lack of so-called dead zones while scanning.
  • The possibility of using near metal structures;
  • Small size EAS tag;
  • Anti-theft system for shops will work even if the acoustomagneticthe label will be metallic material that allows you to protect a sufficiently large range of goods.
  • The reader is able to control the passage width up to 2.4 m.

Sometimes the acoustomagnetic anti-theft systems have additional options to provide protection from thieves. For example, if exposed to the deactivation device already razmahnino tag, the alarm will still go off. In addition, the scanning frame can additionally function as a metal detector. Can be set so that the device will respond to the so-called foil bags.

antitheft protection systemAcoustomagnetic anti-theft systems for stores have a number of negative moments. First, the cost of large anti-theft gates can be quite high. Secondly, consumables necessary for the maintenance of such installation, are rather expensive in comparison with systems operating in electromagnetic and radio-frequency technologies. In addition, commercially available cheap contactless fetters labels. Plus the label is of relatively large size.

Thus, the installation of anti-theft systems is justified only in case of significant risks of financial losses, theft and pilferage of goods and material values.

Operation

EAS system for clothing storesHow EAS systems work? The principle of operation of this device is that stand built in alarm. At attempt of removal of the goods will trigger light and sound signals. The system is installed usually in the area of control. The product thus marked with special labels or stickers, which are removed with the help of deactivator after the payment. One of the pillars of the system is a transmitter. It checks the product to determine the presence of EAS labels and tags. The scanning is performed through the transmission of impulses of a certain frequency. When the actions are labels and hang tags, the sensor is activated. There are signals that are transmitted to the second counter, performing the function of the receiver.

Types of equipment

Acoustic EAS systems are characterized by frequency range. There are four types of such system:

  1. CustomerName.
  2. Radiochastotnyi.
  3. Elektromagnitnye.
  4. Radiomagnetic.

Any component of a security system designed to detect and prevent theft and embezzlement. When selecting the components of the antitheft system, be sure to pay attention to ensure that they were compatible with each other.

Anti-theft mirror

anti-theft systems for shopsWhat other anti-theft system for clothing stores exist today? In areas with limited visibility can be established by a special anti-theft mirrors. For production such models use acrylic plastic. The shape of the mirrors can be various, ranging from simple square, ending with the polygon. The larger the size of the mirror, the greater the area it can cover.

Additional content

The Acoustomagnetic anti-theft systems today come with a list of consumables that you can easily list. Media for anti-theft systems are represented by labels, sensors, tags. The main material used for the manufacture of such articles is plastic. The tags have continuous ribs, so breaking them is virtually impossible. You choose the size this element should be in accordance with the size of the product.

Conclusion

anti-theft system working principleAnti-theft devices today are often installed in large shopping pavilions. Equipment acoustomagnetic type features high reliability and ease of operation. Properly chosen anti-theft system of protection is interconnected with the other elements of the security system such as CCTV or access control, can be an effective tool in the fight against threats of theft.
