Chain store is undoubtedly the best business model to copy. In unifying brand and image, reducing logistics and inventory costs can effectively improve the competitiveness of enterprises. Chain operation has become the mainstream business model of retail industry, home appliance industry, catering industry, medicine and other industries. With the rapid development of chain industry, safety and management problems will become more and more prominent. The larger the chain scale and the more chain outlets, the more difficult the management problems appear day and night. How to improve the overall performance of the chain store, comprehensively and timely understand the operation status of the store, and give correct and rapid command and treatment, has become the most concerned management needs of the chain store head office management department. Combined with the application requirements of chain stores and using its own powerful network video processing technology, it designs a set of economic and complete real-time monitoring system, which can fully meet the needs of remote management of chain stores. Wenyi chain store in Dongguan, Guangdong Province, has adopted this system this year: it selects the intelligent hemisphere camera and remote monitoring management software of Liante micro network.
2、 Chain store security application demand
Since its establishment in 1991, Dongguan Wenyi has three business divisions, namely, “Wenyi office” retail chain, “Wenyi express” direct sales chain, “Wenyi Express repair” business machine maintenance service chain. It has nearly 1000 employees, business outlets all over Dongguan and parts of Shenzhen, and has 50 stores with its own funds, with annual sales of nearly 300 million yuan. It is the largest in China It is one of the most famous office stationery enterprises in China.
In the operation of Wenyi office store, it is very inconvenient for the managers of retail chain business department to know the business situation, personnel status and passenger flow of each store in real time, which is very important for the effective operation of the store. What’s more, the management of business department often receives bad news about the loss of goods in a store, which seriously hinders the development of the chain store. Based on the above problems, the top leaders of the retail chain business division proposed to establish a set of video monitoring system to solve the above problems, and put forward the following requirements for the video monitoring system:
Centralized video monitoring and video storage is realized in the headquarters of the company, and the headquarters management personnel can monitor the operation of each chain store in real time and watch the video;
Within the scope of permission, you can browse the real-time video of each chain store anytime and anywhere through the Internet, and you can know the business status of the store all the time;
The planning and construction of the existing system has good foresight, scalability and secondary development to adapt to the rapid development of the division.
3、 Application of network video monitoring technology in chain stores
In view of the problems and application requirements in the operation and management of Dongguan Wenyi retail chain business department (Wenyi Office), Shenzhen Liante micro company has customized a set of network video monitoring system with high cost performance.
All front-end cameras are connected to the local area network of the chain store through Ethernet cable, and then the video images are uploaded to the company headquarters through the Internet. The video monitoring management server of the headquarters manages all front-end cameras and monitoring clients to realize remote camera setting, remote control, multi screen real-time monitoring, video storage, account management, authority allocation, etc. (see the figure below).
The network video monitoring system can carry out real-time monitoring locally, so that the store manager can fully control the safety of the store goods. On the other hand, the top leaders of the retail chain business department (Wenyi Office) can know the business situation, personnel status and passenger flow of each chain store in real time in a short time at the company headquarters, so as to provide effective basis for various major decisions. When leaders work outside, they can also remotely supervise the branches by connecting computers to the Internet. By replaying the video, the headquarters can reproduce the past events and provide an important basis for various handling decisions.
The design of network video monitoring system follows the concept of front-end network camera selection, transmission part construction and back-end management system design, and constructs a hierarchical network video monitoring system, which lays a solid foundation for future system application, system maintenance, system management and system expansion.
1. Front end system
According to the area and layout of 30 chain stores operated by Dongguan Wenyi retail chain business department (Wenyi Office), a network intelligent hemisphere is installed for each store. The hemisphere has its own pan tilt, which can rotate up, down, left and right. It has a large monitoring range and flexibility. It can be monitored no matter day or night. It has a beautiful appearance and is easy to be hoisted on the store ceiling. The headquarters can control the rotation of the network intelligent hemisphere through the network, so it is convenient to have a comprehensive understanding of the situation in the store.
2. Transmission system
Network video monitoring system is based on TCP / IP network design, can be well integrated into the TCP / IP network. The data transmission of network video monitoring system is not limited by time and region. One of the transmission advantages of network video monitoring system is that it can make full use of TCP / IP network.
3. Management system
The headquarters is equipped with a server, and the network video monitoring management platform software is installed to build the network video monitoring management server. The network video monitoring management server is equipped with corresponding capacity and number of disks to meet the requirements of video storage cycle. The video monitoring management server manages all the intelligent hemispheres of the front-end network through the network, and realizes the functions of real-time video monitoring, video forwarding, centralized video recording, account management, authority allocation, etc. The professional video monitoring client software is installed on the leader’s computer. Through the connection with the video monitoring management server, multi screen real-time monitoring, network intelligent hemisphere PTZ control, video adjustment and other operations are realized. When leaders work outside, they can also access the real-time video collected by the front-end network intelligence hemisphere of each store through the Internet within their authority.
Dongguan Wenyi retail chain business division (Wenyi Office) has 30 chain stores connected to the Internet through ADSL line, and each store cooperates with the headquarters through OA collaborative office system. The maintenance and management of network video monitoring system can make full use of the existing OA collaborative office system resources and improve the system maintenance efficiency. When the current network intelligent hemisphere video is lost, the maintenance and management personnel of the network video monitoring system of the headquarters can control the cashier computer of the store through OA collaborative office system, and use the cashier computer to detect the network intelligent hemisphere in the local LAN, such as testing the local network connectivity of the network intelligent hemisphere, and whether the network intelligent hemisphere video can be viewed locally. When the network intelligent hemisphere works normally, it can detect the relevant settings or dynamic domain name of the store router, narrow the fault search range and quickly locate the fault point.
According to the laboratory test data and engineering practice experience, it needs about 180MB of storage space to store one channel of video in CIF resolution (25 frames / s) for one hour. According to the algorithm, Dongguan Wenyi provides the video monitoring management server with corresponding capacity and number of disks to meet the requirements of video storage cycle.
4. Display system
1. Local monitoring
Each network intelligent hemisphere has its own IP address, web access port (80 by default) and data communication port. The office computers of chain stores can directly input the IP address of a network intelligent hemisphere in the address bar of IE browser, log in to the hemisphere after verifying the password of the hemisphere’s web interface, and display the video images collected by the hemisphere in real time. It can also be used in half within the authority Various parameters of the ball are set.
2. Remote monitoring
① Remote monitoring through video monitoring management server
Because the Internet access mode of each store is ADSL dial-up, the public network IP address obtained by each ADSL dial-up is randomly generated. It is necessary to set dynamic domain name on the router to solve the problem of IP address change. No matter how the IP address obtained by dial-up is, the dynamic domain name will automatically correspond to the IP address obtained by dial-up, and the domain name is always fixed.
The network intelligent hemisphere is set as a virtual server (port mapping) on the network exit router of each store, that is, each data port of the network intelligent hemisphere is opened.
The video monitoring management server identifies the front-end network intelligent hemisphere through dynamic domain name and virtual server (port mapping), and manages the front-end network intelligent hemisphere remotely and centrally.
② Log in to the intelligent network to realize remote monitoring
Different dynamic domain names and each network intelligent hemisphere are set as virtual server (port mapping) on the network exit router of each store, that is, the web port (default is 80) and data communication port of the network intelligent hemisphere are opened.
In the address bar of IE browser of any computer on the Internet, enter the dynamic domain name set on the store router to open the account verification web interface of the network intelligent hemisphere. After verification, you can log in to the network intelligent hemisphere to realize real-time display of video images collected by the hemisphere, and set various parameters of the hemisphere within the permission. Suppose that the dynamic domain name on the LAN router where the network intelligence hemisphere is located is set to neitway.vicp.net We can input it in the Internet Explorer address bar of the remote computer neitway.vicp.net Remote login in the network intelligent hemisphere to realize remote monitoring.
4、 Concluding remarks
The successful application of network video monitoring system in chain stores reduces the investment of managers in human and material resources, improves the work efficiency of staff, and increases the operating income of chain stores. However, due to the high cost of network monitoring equipment, more chain stores still use simulation system, but with the popularity of network monitoring products, it will be more and more widely used in chain stores.
“In 2009, the company will strengthen the expansion of stores, which will increase the operating costs to a certain extent, so when we choose monitoring products, we will consider the convenience and economy of the scheme more. At present, there is no defect in the overall operation of these products, and the management and communication between the head office and branches are much more convenient. ” A person in charge of Wenyi head office said he was “very satisfied”.
