What do you know about supermarket theft prevention?

We should pay attention to anti-theft safety when we go to supermarkets with high traffic. How much do you know about supermarket anti-theft? Today, the editor of SmartView has brought you knowledge about supermarket anti-theft. Let’s take a look!

Use of supermarket anti-theft knowledge facilities

1. Protection settings at the store entrance

1. Anti-theft settings at the door

First of all, the security settings at the entrance The door must fit securely into the door frame. Especially the door lock must be tightly sealed to prevent thieves from using special tools to pry the door open. In addition, emergency exits and cargo transport gates should be made of steel, with steel guardrails outside the doors.

Except for the door for customers to enter and exit, any windows on the door should not be able to allow people to enter and exit, and the glass on the window should be strong in shatter resistance.

2. Anti-theft setting and management of lock keys

(1) Door lock setting Door locks play a decisive role in supermarket security. However, it is a weak link that thieves often attack. Therefore, the following factors need to be considered when choosing a door lock:

① Long metal door bolts are much safer and more reliable when used on double revolving doors or aluminum doors than short metal door bolts.

② Pin-type cylinder locks should not be used on emergency exit doors.

③Sturdy box-type door bolts should be used with high-quality pin cylinder locks to prevent thieves from prying open the door.

④ Double pillar bolt locks should be used for doors at the main exit of supermarkets and doors that are not used as emergency exits.

⑤The single cylindrical lock needs to be opened from the outside. By turning the nut inside, the door can be opened from the inside without a key.

⑥Padlocks are often used on warehouse doors where cigarettes, film, and other small items are stored. They can also be used on tight load-bearing doors, ceiling openings, and other locations where managers wish to restrict access to authorized persons.

(2) Key management:

① The words “No copying allowed” should be posted on all keys.

②Keep all copied keys in a safe or locked cabinet.

③Do not indicate words such as "warehouse" on the copied keys. Use code markings as much as possible.

④Replace the key to the supermarket’s exterior door once a year.

⑤ If the key is lost by the holder, or the holder leaves the store or is fired for various reasons, the key must be reconfigured.

⑥Key holders are prohibited from lending keys to other employees.

⑦Record the name of the person who issued the key, record the type of key (such as front door, computer center, etc.) and the date of issuance, and require employees to sign after receiving the key.

⑧Prevent using one key to open all doors.

3. Anti-theft measures for supermarket roof or wall openings

Roof openings, air conditioning outlets, vents, skylights or openings on walls in supermarkets are frequent targets for thieves. Therefore, these openings must be covered with steel bars or metal plates and connected to the alarm.

Measures for roof or wall openings include the following:

(1) Cover the opening with a thick metal plate.

(2) Use a high-quality padlock to lock the opening internally.

(3) Use round-headed rotatable bolts and one-way security screws to prevent thieves from entering from the outside.

4. Anti-theft measures for external windows

The glass materials used for the front windows of supermarkets are different, and their resistance to damage is also different. The side windows and rear windows have become the first choice targets for thieves. Therefore, there is no need to open windows unless it is necessary for aesthetic reasons. Of course, if windows are retained for natural lighting and other reasons, they should be protected with steel mesh or metal panels.

2. Various types of anti-theft devices and their uses

1. Electronic anti-theft system

The electronic anti-theft system (EAS) uses electromagnetic, microwave and wireless respectively. Technology, when goods are taken out without payment, an audible and visual alarm will be generated to ensure the safety of the goods.

The EAS system consists of the following components.

(1) Induction labels mainly include paper labels and hard labels.

(2) The decoding board and puller decoding board are placed at the checkout area to invalidate the paper labels. After the customer pays, the clerk needs to bring the goods close to the decoding board to invalidate the labels. The puller is used to pull the buckle from the hard tag after the customer pays, so that the product can be taken out without generating an alarm. Hard labels are reusable.

(3) The detection door has the following types depending on its working mode:

①RF system (8.2MHz)? It is a radio frequency transmitter and radio frequency receiver composed of a pair of antennas, installed On both sides of the customer exit channel, the width of the channel is 1 to 2m. When a customer brings out goods without paying, when the label on the goods passes the antenna detector, it will interfere with the signal received by the antenna and generate an alarm. This device is suitable for In supermarkets, department stores, video stores, clothing stores, etc.

②Single antenna system (2.1MHz) - It uses a single antenna installed in the center of the store exit channel. The detection distance on each side is about 1.2m. It is mainly suitable for clothing, leather shoes, wallets, handbags, etc. Hard labeled items.

③Electromagnetic (EM) system - it uses electromagnetic waves for detection and is suitable for libraries, supermarkets and other places.

2. Shopping mall anti-theft alarm system

(1) The design of the deployment point is based on the site conditions in the shopping mall. Point-type intrusion detectors, linear intrusion detectors, and surface-type intrusion detectors can be appropriately selected. Detectors, space-based intrusion detectors. For example, glass break detectors can be installed on doors and windows. In order to reduce the false alarm rate, several properties of the detection probe can be combined.

(2) Alarm controller The alarm controller should be able to receive the alarm signal from the intrusion detector, issue an audible and visual alarm and indicate the location of the intrusion. The audible and visual alarm signals should be maintained until manual reset. After reset, if an alarm signal is input, the audible and visual alarm signals should be re-issued. In addition, the alarm controller can also provide DC operating voltage to all detectors interfaced with the machine. Once something happens, an alarm will be issued immediately, the lights will be turned on, and the video recorder of the surveillance system will be started to record the alarm scene in time as evidence for investigation. This series of work is automatically completed by the host. The alarm controller can be made into box type, wall-mounted type or cabinet type. According to its capacity, it can be divided into single-channel or multi-channel alarm controllers, and multi-channel alarm controllers are mostly 2, 4, 8, 16, 24, and 32 channels. When choosing an alarm controller, its capacity should generally be slightly greater than the number of alarm probes to facilitate future expansion.

3. TV surveillance system

(1) The design of the defense point should cover the entire mall as much as possible. The camera should be colored as much as possible to provide a better quality picture. It is best to choose a hemisphere for appearance. Type protective cover, which is not only concealed and beautiful, but also does not damage the overall layout of the shopping mall.

(2) The back-end control and record display part can flexibly combine the equipment in the control room according to the specific conditions of the front-end installation monitoring point.

4. Complete security system

If the above three systems are connected, a strict security system will be formed. In the electronic anti-theft system, once someone goes out with goods without paying, an alarm will sound. At this time, the alarm signal can be transmitted to the monitoring host in the control room. The host will automatically cut out the video signal to the video recorder and start the video recorder at the same time. Real-time video recording provides an important basis for evidence collection. Likewise, if a burglar detector detects an intrusion, the lights on the scene can be turned on and the video recorder can be started to record.

5. Other anti-theft devices

(1) The acoustic and magnetic anti-theft system adopts the tuning fork vibration principle, that is, the transmitting support emits 58KHz low-frequency radio waves. When a tag composed of disorderly arranged amorphous metal sheets used in aerospace enters the detection area, the detection system excites the tag to vibrate and emit attenuated infrasonic signals. At the same time, the system stops transmitting and the receiving program starts. After 4 to 8 cycles of receiving and sampling, and after testing and confirming that it is a tag, an audible and visual alarm will be issued.

(2) The label is a material used to protect goods in an acousto-magnetic anti-theft system. It is composed of two disorderly arranged amorphous metal sheets. After entering the detection area, it vibrates with the polarizing magnetic sheet. and reflected to the receiving support.

(3) Soft labels are small in size and are often used to protect cosmetics, food and other commodities. Easy to stick, hidden inside the product and cannot be reused.

(4) Hard tags are larger in size and are used to protect clothing, shoes, hats and other goods. They are difficult to damage and can be reused. They have a long life and can only be opened with a professional nail remover.

(5) The cigarette protection box is used for anti-theft protection of high-end cigarettes. There is a label sensor inside the box, which can be opened with a special opening device at the checkout counter and can be reused.

(6) Tape protection boxes are used to protect CDs, VCDs, DVDs, floppy disks and other commodities. They can be opened with special equipment at the checkout counter and can be reused.

(7) Wine bottle protective sleeves are used to protect high-end wine, beverages, and bottled and canned items. They are shaped like a rope loop and can be freely retracted. They can be opened with special equipment at the cashier and can be reused. .

(8) The nail remover is a special device used to open hard tags. It is usually placed at the checkout counter. There are two types: gun type and button type.

(9) The support is composed of a transmitting support and a receiving support. It is usually installed at the customer's exit. If the product is not demagnetized, the support will sense and send out an audible and visual alarm.

(10) Demagnetizer is a device installed at the cashier for degaussing. It is divided into two categories: contact type and non-contact type.

6. Maintenance and use of anti-theft alarms

(1) Maintenance of alarm system:

①Detection and maintenance methods. The detection should be carried out in two situations: one simulates the situation of illegal intrusion on site and assesses the alarm responses of various detectors; the other simulates possible objective interference situations and assesses the false alarm responses of various detectors.

Finally, according to the alarm response, the alarm sensitivity and protection distance are repeatedly adjusted to make them effective and reduce false alarms.

②Irregular maintenance. In addition to regularly testing the alarm system, faults discovered at any time should also be promptly eliminated. Temporary faults should be checked step by step, from power supply, controller, circuit to detector, until the fault point is found, and corresponding measures should be taken to eliminate it. Unscheduled maintenance is carried out almost every day, and the maintenance is based on the customer's telephone notification or the reflection of the duty record and the faults found during the inspection.

③ Precautions during maintenance. Work must be done carefully, and the drawings and materials of the customer's alarm system must be kept confidential and must not be lost. All personnel involved in the installation and maintenance of alarms must be registered with the public security agency to have maintenance qualifications, and must pay attention to safety. When working with electricity, attention should be paid to both personal and equipment safety to prevent electric shock and equipment burnout accidents. After replacing the detector, the sensitivity must be readjusted, and the protection range and distance must meet the performance requirements of the original device.

(2) The use and adjustment of the alarm system:

① When using the alarm system, there must be a dedicated person responsible and managed, and the user is required to be relatively stable to facilitate confidentiality.

② Before the alarm system is put into use, each detector circuit and alarm circuit must be tested for problems first. It can only be used after the test confirms that there are no problems. Generally, alarms have automatic detection functions.

③When using the alarm, pay attention to its environmental requirements. Since there are many types of alarms, such as commonly used magnetic switches, active infrared, passive infrared, microwave, ultrasonic, glass breakage, etc., their working principles are different and their scope of application is different. Therefore, in order to select and use alarm equipment well, it is necessary to understand the characteristics and applicable environment of various alarm equipment.

④ When using an alarm, in addition to paying attention to environmental requirements, you must also master its technical performance requirements before using it correctly.

⑤ When using the alarm, in order to reduce the false alarm rate (that is, how many false alarms and missed alarms are contained in a hundred alarms), the protection range and the sensitivity of the detector must be adjusted. When making adjustments, fully consider the use environment and try to eliminate interference. The sensitivity of the detector should not be adjusted too high or too low. If the sensitivity is too high, interference and false alarms will increase; if the sensitivity is too low, false alarms will easily occur.

Layout and management

1. Anti-theft principles for product display

Whether it is a department store or a supermarket, open-shelf sales stores The types of goods that are most easily lost are mainly cosmetics, shampoo products, cigarettes, films, batteries, chocolates, clothing/clothing (such as cashmere sweaters, fur coats, leather jackets, etc.), CD/VCD, which are relatively expensive and convenient. Goods carried. The loss of such goods accounts for about 50 to 70% of the market's losses. If they are effectively protected, it will be of great help in reducing the overall loss.

In an open store, the products that are most likely to be stolen are displayed where the salesperson’s sight is most frequented. Even when the salesperson is busy, he can take care of these products. This will increase theft. The difficulty in committing a crime is conducive to the prevention of merchandise theft; in addition, merchandise that is most susceptible to theft should not be placed near the exit because there is a large flow of people and it is difficult for the salesperson to find or distinguish the thief.

In addition, you can also adopt a centralized approach to concentrate some easily lost and high-priced goods in a relatively small area in a hypermarket to form a shopping space similar to a "boutique", which is also a good choice. This is a very good "safe" way of displaying goods, which is very conducive to preventing theft of goods. To minimize losses, in addition to "safe" display methods, an advanced electronic commodity anti-theft system must be installed.

2. Anti-theft layout of various stores

Different types of stores should consider different anti-theft measures in store design.

(1) For small supermarkets, it is not necessary to install an electronic anti-theft system, but anti-theft mirrors widely used abroad can be used for protection. Anti-theft mirrors are generally installed in every corner of the supermarket to make it convenient for salespeople. Comprehensive monitoring of the entire supermarket, combined with safe product display and sales assistant inspections, can generally meet their anti-theft needs.

(2) For large department stores, clothing accounts for the majority of product displays. Open displays are generally used in store designs. In areas with high theft rates, partially closed protection methods are adopted for fur coats, women's underwear, high-end suits and other products that are most easily lost, so as to facilitate the installation of electronic commodity anti-theft systems to ensure the best anti-theft effect.

(3) Video stores are areas with a high incidence of theft cases. If a video store selling open shelves does not install an electronic commodity anti-theft system, its anti-theft effect will be greatly reduced. Since audio and video stores are generally not large in area and have only one entrance and exit, it is necessary to consider leaving space for the electronic anti-theft system when designing the store. This way, the shelves will not be placed too close to the anti-theft system, causing the entrance and exit to be narrow. Consider anti-theft requirements in advance when opening a new store. With the same anti-theft effect and the same business area, the number of anti-theft systems required will be greatly reduced, and the investment in anti-theft systems will also be greatly reduced.

3. Management of loss-prone areas

In addition to the boutique area, supermarkets are areas that are more prone to loss. Such as daily chemicals, stationery, high-end underwear, footwear area, fitting room, etc.

(1) On holidays or daily basis, security officers are arranged to patrol the area from time to time to detect abnormal customers.

(2) Supervision points

① Supervise customers’ bad behaviors and promptly detect theft, such as removing product packaging, putting other products into a certain product package, changing packaging, and Hiding goods on the body, destroying anti-theft tags, etc.

② Check the negligence and loopholes of the floor personnel in preventing theft.

③ Check whether the employees in the fitting room implement the system of issuing/receiving licenses and checking and verifying the fitting room.

(3) Management regulations

① Floor personnel must correctly implement the regulations on the management and use of anti-theft tags and price tags.

② Employees in the fitting room shall implement the management and use regulations of the fitting room.

②Customers cannot bring non-boutique area products into the boutique area and can only leave them outside temporarily.

③Customers purchasing goods in the boutique area must check out in the boutique area.

④ Check whether the customer's receipt is consistent with the product, especially whether the cashier's packaging meets the packaging requirements for the products in the boutique area.

⑤Solve the alarm problem of electronic security doors.

(3) Management regulations:

① Please refer to the following chapters for detailed procedures for solving the alarm of electronic security doors.

②The packaging of checkout products and the handling of receipts in the boutique area must comply with the relevant regulations of the supermarket on the boutique area.

③Whether the counters or display cabinets in the boutique area are locked and closed at all times when not on sale.

④ Whether all valuable samples released in the boutique area are labeled with anti-theft measures.

⑤Whether the goods sold at the counter in the boutique area adopt the sales method of paying first and picking up the goods later.

⑥The security personnel in the boutique area cannot do any work on behalf of the cashier.

⑦The security personnel in the boutique area are responsible for monitoring the cash security at the boutique cash register.

5. Management of home appliance pick-up port

(1) Setting:

①Personnel setting. The pick-up port for major appliance inspections is set up with safety officer posts, and a non-stop duty system is implemented during business hours.

②Device settings. An anti-theft alarm system is installed on the rolling shutter at the delivery port for detecting large appliances. If the door is forcibly opened without password permission, an alarm will be issued.

(2) Supervision points:

① Every order for major electrical appliances to be delivered must be inspected and signed by a safety officer.

②The security officer checks whether there is a cashier receipt, whether there is any abnormality in the cashier receipt, whether the product name, model, and item number are consistent with the receipt, whether the quantity is consistent with the cashier receipt, and whether the receipt is consistent with the cashier receipt. Whether the ticket is stamped with inspection and delivery stamps, and whether the packaging of the goods has been sealed.

③Whether the customers picking up the goods are in good order and whether the customers are standing outside the designated pick-up area.

④Whether the door for picking up goods is closed at any time, and whether the pick-up personnel register the goods going out.

⑤Whether the receiving office controls the process of picking up the goods, and whether the various seals for picking up the goods are kept in the drawer.

(3) Management regulations:

① Sales and delivery process of major appliances.
