Cube Beauty Supermarket Anti-theft System.

Install anti-theft system software and hardware: such as soft tags, hard tags, burglar alarms. Paste warning signs in places where goods are likely to be stolen:

Shopping mall theft is also a crime, so please don't defy the law. Install monitoring systems, monitors, and display valuable and stolen goods in a more visible position. Train salespeople on anti-theft knowledge.

1. Install anti-theft system software and hardware: such as soft tags, hard tags, and anti-theft alarms.

2. Paste warning slogans in places where goods are easy to be stolen: Stealing in shopping malls is also a crime, please do not defy the law.

3. Install monitoring systems and monitors, and display valuable and stolen goods in a more obvious position.

4. Train salesmen on anti-theft knowledge.

There are three main types of supermarket anti-theft systems: radio frequency, acoustomagnetic, and electromagnetic waves.

Radio frequency systems.

Radio frequency (RF) has been around for more than 30 years and is one of the earliest electronic anti-theft systems. It uses radio frequency as the system to transmit and receive detection signals, and the detection frequency range is generally megahertz. The detection rate of radio frequency systems is generally about 80%.

Because the anti-theft tag is a toroidal type, many coil items or electronic products with a similar frequency to the tag will trigger the system, causing false alarms in the system. Moreover, the radio frequency system is completely shielded by the metal tin foil, and the anti-theft label close to or attached to the metal tin foil will invalidate the tag, causing the system to underreport. The biggest advantage of radio frequency systems is that the system cost is very low.

The radio frequency system has two types of tags, soft and hard, which can protect most items in the mall. The distance between the two supports should generally not be greater than meters. The radio frequency system has two installation methods, vertical and channel, which are used to protect department stores, clothing appliances, supermarkets, etc.

It has a wide range of branded products to choose from and is inexpensive.

Acousto-magnetic system. Tuning forks only cause resonance if they oscillate at the same frequency. Acousto magnetic systems apply this physical principle to achieve operation with almost zero false alarms. When the acoustomagnetic system tag fixed to the product enters the detection area of the system, it will resonate, but the system will only send an alarm after the receiver receives four consecutive resonance signals (once every 1 50 seconds).

The acoustic and magnetic system is characterized by a high anti-theft detection rate, almost zero false alarms, no metal foil shielding, good anti-interference, and wide protection outlet (a single system can protect up to 4 meters). The acoustic and magnetic system has both soft and hard anti-theft labels to protect most types of goods in the mall, and the soft label is small in size and can be demagnetized repeatedly, which is the preferred technology for anti-theft source labeling programs. Acousto-magnetic systems include vertical systems, channel systems and concealed systems, with more than 10 models to choose from, which can be widely used in department stores, supermarkets, specialty stores, audio and video stores, grocery stores, pharmacies, and office buildings and other environments.

The acoustic and magnetic system is the latest technology of anti-theft, which is only more than 10 years old.

Electromagnetic wave system.

The electromagnetic system, which uses electromagnetic waves as a detection signal, has been around the same time as the radio system and has a history of more than 30 years. The detection rate of electromagnetic wave systems is generally about 60%. Systems are susceptible to false alarms or non-positives due to the influence of magnetic or metallic substances.

Its advantages are that the label is minimal, the label is cheap, it can be demagnetized repeatedly, and it is suitable for the protection of specific products such as books. There are two types of electromagnetic wave systems: vertical type and channel type, and the outlet width is generally in meters. The application environment is mostly in libraries, bookstores, audio-visual stores, etc.

Although supermarket shopping meets the needs of most consumers, there are thousands of items in the huge supermarket, and there are often some unconscious people who will take the sheep by the hand, which also brings a certain amount of trouble and trouble to the people who run the supermarket. The supermarket anti-theft device is to meet this demand and came into being, under the work of the supermarket anti-theft, it can reduce the theft of items as much as possible and reduce the loss. Anyone who has ever been to a supermarket knows that the entrance to a supermarket usually has a door-like device, and if you bring an item with a magnetic stripe, the device will sense it and make a Didi alarm sound.

This also involves the principle of supermarket anti-theft, how does the supermarket anti-theft device work, let's take a look! Supermarket goods are generally equipped with two kinds of anti-theft devices, one is a small magnetic stripe, commonly known as "soft label", the other is a button type magnetic device, commonly known as "hard label", they are the use of magnetic response principle to prevent theft, the alarm device at the door of the supermarket is also known as the "loss prevention door", which is equipped with a magnetic device. If the product has not been demagnetized and passes through the damage prevention door, an alarm will be given.

After the customer selects the goods and pays at the cashier, the cashier will degauss the goods with "soft label" and "hard label", if it is a "soft label", it will be degaussed on the degaussers on the cash register counter, and if it is a "hard label", a special tool will be used to hold the "hard label" and the product, so that the goods purchased by the customer can safely pass through the "loss prevention door". Seeing this, you should understand the reason why every item has to be scanned every time you check out, it can not only record**, but the main reason is degaussing.

By detecting the label signal on the product by detecting the antenna, it is judged whether it is alarmed.

The main function of the usual access control system of the supermarket is to prevent the take-out of things, the principle is that the packaging bag of each item in the supermarket has a barcode, and the supermarket personnel will also nail the idea label, and some bulk things (candy, vegetables, snacks) will also be labeled with a barcode after weighing, containing ** and other information.

When checking out, the cashier will scan the barcode, one is the checkout price, and the other is to register the barcode information. There is a barrier at the door of the supermarket, and you can only go out through the barrier, and the function of the barrier is to detect whether the items that have passed have been checked. If there is no scanning, an alarm will sound when the checkout is passed.

A detector is set at the exit or cash register channel of the supermarket, and the detector comprises a transmitter and a receiver, when the transmitter sends a signal at a specific frequency, the receiver receives this signal, and then produces a monitoring area. When an unprocessed EAS tag passes through the detection area, it causes interference, and when the receiver detects this interference, an audible alarm is triggered.

Many supermarkets will install alarms, what are the main types of alarms? Today is a long time to see.

Tsing Yi's answer was a good one.

Problem description:1What is the name of the instrument that scans the barcode when you go to the cashier to pay the money after shopping at the supermarket? If you don't pay the money here, will you call the police?

2.After paying the money, there is usually a conversation between the cashier and the gate that the front has to pass between the two vertical things, what is that called? Will I call the police if I pass by with goods that I haven't paid?

3.There are other anti-theft facilities inside the supermarket, what else is there besides the camera?

Analysis: 1. It is called the barcode scanner (instrument) containing infiltration, the name of each manufacturer is different, and the function is the same. If you don't pay the money, you will go out directly, and if you don't have a magnetic label, you won't call the police, and if you have a label...

2. The vertical thing is the radio frequency detector (wall, channel), which is the same as the above when you don't pay the money;

3. In addition to the monitoring system of the camera, there will generally be infrared + microwave anti-theft equipment and fire-fighting equipment.
