Three major shopping mall security applications

Security in shopping malls is also a complex system. It is mainly composed of anti-theft alarms, monitoring technology, and patrol system. Each subsystem is composed of multiple smaller systems to form a security wall for shopping malls, which not only provides security for shopping mall products. It also provides a safe and comfortable environment for shoppers. Today, we mainly look at how burglar alarms, surveillance and patrol systems in shopping mall security systems work together.

The loss of electronic merchandise anti-theft system products undoubtedly aggravated the burden on enterprises. For this reason, the anti-theft alarm industry was born. Loss prevention has gradually become the focus of domestic business leaders. Electronic anti-theft alarm technology in the mall has 7 basic types.

(1) Acoustic-magnetic system The tuning fork only causes resonance if the oscillation frequency is the same. The AcustoMagnetic system uses this physics principle to achieve nearly zero false alarms. When a product's acousto-magnetic system tag enters the system's detection area, resonance occurs, but only at the receiver. The alarm is issued after four consecutive resonances (once every 1/50th of a second).

The characteristics of the acousto-magnetic system are high anti-theft detection rate, almost zero false alarms, good anti-interference, and the protection of the export width of up to 3.5 meters, there are two anti-theft labels soft and hard, for most types of shopping malls can be protected, and Demagnetization can be repeated, even if the system is still working at the POS cash register.

The acousto-magnetic system includes vertical system, channel system and concealed system different types. There are more than 10 models to choose from, which can be widely used in department stores, supermarkets, specialty stores, audio-visual shops, grocery stores, pharmacies, etc. Office buildings and other environments.

(2) Radio System Radio Frequency (Radio Frequency, RF) uses radio waves as signals for transmission and reception, detects electromagnetic waves in the frequency range of 7.4 to 8.8 MHz, and has a center frequency of 8.2 MHz. This causes an interference at 8.5 MHz caused by the tag, thus triggering an alarm. . The biggest advantage of the radio system is the very low system cost and easy installation. However, since its anti-theft tag is a toroidal coil type, the system is susceptible to interference from some items, such as electronic products such as cash registers and metal objects, which cause false alarms or non-reports of the system.

The radio system has two labels, soft and hard, that can protect most items in the mall. The distance between two bearings can not be more than 0.9 meters, usually used in a shopping mall with only one import and export. The radio system has two types, vertical and channel, for the protection of department stores, clothing stores, and supermarkets.

(3) Electromagnetic wave system Electromagnetic wave system (Electromagnetic System) uses electromagnetic waves as detection signals. The electromagnetic wave system has the smallest label, the label price is also low, and the demagnetization can be repeated, but it is susceptible to a false alarm due to the influence of magnetic or metallic substances. The protected exit width is generally about 0.9 meters. The system will not affect magnetic objects (such as audio tapes, video tapes, magnetic cards).

The new generation of channel-type electromagnetic wave system is a software-controlled electronic anti-theft system, using digital processing technology and degaussing system, cashier monitoring, closed-circuit television monitoring system. The use of fast degaussing plates enables repeated demagnetization and high system costs. There are two types of electromagnetic wave systems: vertical and channel. The application environment is mostly in libraries, bookstores, sound shops, hotels, supermarkets, etc.

(4) Microwave System The microwave system (Microwave System) uses microwave as a detection signal and is not easily affected by the surrounding environment. It can be installed in a flexible and concealed manner (such as concealed under a carpet or suspended from a ceiling), and is suitable for interior decoration and aesthetics. advantage. However, due to the large scale of Shengying, it is impossible to arrange products in a certain area. This would limit the use of space for merchants with a high price of land. Therefore, it is suitable for use in large department stores and large music stores and fashion stores.

(5) Frequency division system Frequency division system (SplitFrequency) is a high-tech frequency division technology and ultra-low frequency radio wave signal anti-theft system. When a security tag enters the detection area, the tag receives the signal transmitted by the transmitting device, divides it into half, and then transmits the divided information to the receiver. Only when the receiver receives half the signal Sending an alarm can effectively avoid interference from other radio waves. The system has the advantages of light weight, small size, low price, stable performance, high detection rate, good anti-interference, and is not likely to cause false alarms. There are two kinds of vertical and concealed products, which is an ideal anti-theft system for clothing and apparel.

(6) Wisdom system The unique technology of the smart system application is an internal integrated circuit control, battery drive, hard tag and alarm group. When the tag is picked up or taken out of the store along with the product, the system automatically sends an alarm. The system enables the entire store to be protected, with no errors, and the labels can be reused without damaging the merchandise. It is used to protect valuables, such as fashion, leather, and clothing.

(7) Destruction principle The anti-theft system of the system destruction principle is a hard tag or magnetic lock. The ink is contained in a hard tag. When the thief attempts to remove the hard tag, the hard tag will eject ink, contaminating the body of the goods and the burglar. Magnetic lock is very difficult to dismantle, forcibly remove it will destroy the goods, it is easy to use, has a good deterrent effect, and the cost is very low, applied to clothing, glasses, jewelry, ties, silk and other goods, the label can be reused.

Electronic monitoring system shopping mall monitoring is to avoid the few links, but also the most important one in the security system, high-definition video surveillance real-time monitoring of the mall conditions, but also provide evidence for post-examination.

1. The biggest feature of supermarket monitoring is that customers can choose their favorite products, and finally pay to the exit to meet the customer's free choice. For supermarkets, what is most concerned about is managing goods and avoiding customers' actions; in order to respect customers, supermarkets can only take preventive measures.

By using a monitoring server system, cameras installed on ceilings and other locations can easily monitor numerous shelves to see if there is a theft in the supermarket; if the theft is discovered, the video data can be played back to the customer at the payment place. No need to have any dispute with the customer. When looking at the shelves, if you find that the goods are misplaced and there are many places that are in disorder, you can send someone to sort out immediately. When the system plays back video, it can enlarge the part of the data that needs to be highlighted, such as the action of the customer stealing the item.

2. People flow monitoring Daily working hours and weekends are often times when there are more people in large supermarkets. People who meet holidays are even more prosaic. Supermarkets must make appropriate arrangements according to the flow of people in the supermarkets to facilitate the flow of people, or to increase the number of people to shorten the waiting time for customers; in order to avoid accidents caused by many people.

The use of a monitoring server system enables supermarkets to understand the number of customers in a timely manner, and conduct necessary work such as grooming. In addition, the system can also record all the scenarios in detail, record the time and place in the data, and provide detailed information for the market personnel to analyze the market trend. Through a systematic analysis of video data, you can know which season, what festival, and even what time period is specific to the day. The passenger flow is the most prosperous; you can also know what items and which selling points are most attractive to customers.

3. Employee Work Status Monitoring The attitude of employees directly affects the customer's desire to purchase. Because home is a free market where customers choose their products freely, when operators consider various factors such as customer psychology and operating costs, they will not arrange too many sales staff and will only arrange certain staff to guide customers when they need it. Salespersons work at the forefront of dealing directly with customers, and their performance often directly represents the image of the home. Using a digital hard disk video recording system, it is possible to assess and assess the status of sales employees, observe the employees' on-duty status within the prescribed scope, and the attitude of employees to receive customers. Finally, the system's video recording function can also save the employee's working status as a basis for assessment.

4. Non-working hours supermarket safety monitoring When the non-24-hour operating home is always off work, the security of the goods in the shop requires security personnel to carry out patrols to protect. For existing home sites, security personnel patrol a large area. If there are few people, there will be no guarantee of sufficient patrol density. If there are many staff, the cost of home operations will increase. The use of digital video recording systems solves this problem. By installing low-light lenses and infrared lenses in homes and equipped with various types of alarm sensors, security personnel can monitor the situation in the home in the monitoring room and effectively protect the property safety of the home. When there is something happening in the monitoring range, the sensors connected to the system will automatically alarm and realize sound and light alarms through the output of the alarm host, so that the security staff on duty can know what is happening in the house at any time and take corresponding measures in time.

5. The extended monitoring function can support the POS (electronic cash register) system through expansion; it bundles the sales data of the POS cash register system with the synchronized cash register scene image, and is archived as a sales record, and acts against suspected theft. Through the input of product name, cashier number, cashier number, serial number, transaction time and other related query data, you can quickly find the corresponding image records in a large number of records, and through the analysis of image records on-site sales of goods and cash register records The POS data from which to find problems and take appropriate management measures. RFID (wireless intelligent identification technology) can also be extended to supermarket monitoring. It can automatically identify target objects through radio frequency signals to obtain relevant data and superimpose relevant video images, realizing real-time monitoring of any commodity in real sense. Completed the following functions: tracking of goods, so that each company is very clear about the situation of each container leaving the warehouse; prevention of internal theft, the key to solving problems is to prevent the loss of the supply chain; prevent return fraud, reduce management errors, avoid goods Dislocation; the monitoring system forms the mutual complement of intelligence transmission and classic security. The identification work can be performed in various harsh environments without manual intervention, and the distance of reading and writing labels can be further realized, thus real prevention of theft.

The shopping mall's inductive electronic patrol system has monitored and intruded alarms. The inductive electronic patrol system is applied to any shopping mall as a supplement to the monitoring and alarm system.

According to the requirements of shopping malls, the monitoring system and the actual survey of the site to set the electronic patrol system, in addition to the relevant standards as the basis for system construction, the requirements of the mall and the actual situation on the site will directly affect the quantity of equipment. System architecture methods, use functions, equipment grades, etc. must therefore be rigorously and systematically analyzed in technical design.

Determine the risk level and protection level of the system: There is no clear risk level requirement for the shopping mall, but in the actual design, the system design must be based on the requirements of the high-risk industrial system design and the needs of the mall itself as the main basis.

The patrolling officer inspects and arrives at the appointed place according to the designated route, and records the abnormal situation. The patrol bar that records the inspection information is brought back to the management center, and the system management software immediately displays the inspection route and arrival of the inspector. The time and name of each patrol point and the missing patrol points, and an inspection report was generated as required. If the task is not completed within the specified time, or the event is recorded as an anomaly, the corresponding person or event must be processed.

Inspection plan:

(1) Design the patrol route Firstly, design the patrol route. According to the patrol route, select the number and location of the best patrol point. The patrol point should be set near the objects that need to be guarded against and some monitored dead areas, and customize the system. The patrol time for every two patrols.

(2) Set the patrol team to set up inspectors, assign shifts and several patrols for each shift. Arrange the number of patrols in each patrol group and the inspection time. Each patrol should conduct patrols according to the specified patrol time and patrol locations.

(3) patrol equipment configuration Each patrol group is equipped with a patrol bar, each patrol staff is equipped with an identification button, a wireless information button is set for each patrol point and a mount is correspondingly set.

Other intrusion detection and alarm systems Intrusion detection and alarm technology systems refer to a security and prevention technology system that uses advanced scientific and technological means to make the necessary safety precautions invisible in the warning zone. Once an illegal intruder enters the warning zone, The system can immediately sound and light alarms and indicate the alarm address time.

Intrusion alarm system usually consists of three parts: detector, transmission channel and alarm controller. The selection and installation position of the front-end detector is very critical. According to the site conditions in the mall, the appropriate point-type intrusion detectors, linear intrusion detectors, surface-type intrusion detectors, and space-type intrusion detectors are selected. Form a strict precautionary area. Anti-intrusion alarm system is mainly used for anti-theft in shopping malls during non-business hours.

The application of RFID technology to the mall intelligent management system, RFID's two major functions are the most critical: 1 large capacity data read and write and storage; 2 can identify the physical space of mobile information, including customer movement traces and goods are turned traces. The application of RFID can make the intelligent management of shopping malls have more application value. As RFID can read and write and store “dynamic” information, the following changes have occurred in traditional shopping mall intelligence systems:

1. Transition from "shopping-oriented results" analysis to "shopping-oriented processes" analysis due to the involvement of RFID. The mall intelligent management system can not only collect the records of customers' shopping results from the POS machine, but also track the intermediate process information such as the movement traces of the customers in the mall and the frequency of the products being picked up and flipped through RFID signals, which makes it possible to analyze the shopping process. .

2. From "purchase record" analysis to "abandoned purchase" analysis, the traditional intelligent management system can only understand the customer's purchase history that has occurred through the POS machine, and the RFID-based intelligent management system can collect the customer's purchase through RFID signal acquisition. behavior. For example, after a customer places a product in a shopping cart, the customer removes the product after a while. Analysing customer buying behavior helps to increase sales
