Programme introduction

According to the actual situation of the shop site, the program needs to use the existing network resources, at the same time to use the ADSL line and the company network for network data transmission, to achieve the full function of the network monitoring system at all levels. Monitoring programs need to be in the head of the company set up a total monitoring center, so that it becomes a network monitoring station, can be arbitrarily adjusted to see any one of the shops in the system screen.

Background and challenges

Characteristics of the chain of the industry reflects the various shops scattered and mostly not in a city or area, the environment is relatively complex, but lack of supervision and management of the company, to the shop management bring a lot of inconvenience, to keep abreast of developments in the shop, timely adjustment of marketing strategy, fully the essential function of network monitoring is a save manpower and material resources the best aid management scheme. If the program to be implemented, the new business management, improve the overall brand image will play a positive role in promoting.

Solution

The super class chain store monitoring system adopts the whole grid structure, and each monitoring device is used in the project. The system architecture is shown in the following figure:

Front camera nearby by category 5 cable into the access layer switches, dome camera, gun type camera, dome camera video signal were through the network transmission; dome camera control signal also through the network transmission to the front of the camera, control and management.

Alarm system for preventing important room (such as financial room, the leadership of the office, valuables storage room, etc.), the important rooms (such as network center, data center, equipment) intrusion alarm, various functions of alarming and detecting device installed in the front, anti-theft alarm host by centralized management and operation control, such as cloth, disarm and so on, when the system to confirm the alarm signal automatically sends out alarm signal, suggesting the relevant management personnel timely processing of alarm information.

Video monitoring system combined with alarm system, constitute a comprehensive security system. On the one hand, the system will automatically send the alarm signal is transmitted to the control center, the officer on duty by alarm keyboard and electronic map display to determine the alarm positioning; and on the other hand, can also be through sound and light alarm remind personnel on duty of attention, the rapid processing of alarm.

The central management of the shop using the integrated platform, the whole system to achieve the management of the same time, can decode the output analog video signal to facilitate the display access. Video storage device using a network hard disk video recorder, each network hard disk video recorder can access up to 16 channels of video signals. Management computer set in the security center of the store, through the BS/CS client login system, to achieve a unified management of the entire video management system.

Store chain
Store chain store monitoring system using a full grid architecture, due to the smaller area of the store, and the formation of the network environment are temporary structures, each monitoring device access to the store on a small router can be. The system architecture is shown in the following figure:

Front of the camera through a category 5 cable into the store small router, installed inside the shop camera video signal were transmission line through the network; the control signal of the camera also through the network transmission to the front of the camera, control and management, store management with received silver computer sharing to achieve the store monitoring equipment management.

Storage devices using network hard disk video recorder, each network hard disk video recorder can access up to 8 video signal.

signal transmission

Super class chain store video signal using TCP / IP through the project security specific transmission network to the center computer room management; video signal can be through the camera master stream way are respectively transmitted to the monitor and the NVR store video display.

Store chain video signal is also used in the same way TCP/IP transmission, the whole system is located in the store through the small router access to all of the signaling transmission through the device is completed.

Video storage

In the backend system uses fly LIC network hard disk video recorder stores video signal, the system structure is simple, the comprehensive performance of the system greatly depending NVR (network hard disk video recorder) itself.

System design of image storage time for 15 days, the NVR selection shall be calculated NVR quantity and internal hard disk capacity and the number of the combining way, or resolution of the front of the camera.

According to the calculation formula of universal storage capacity: can be probably calculated that a few road video can store many hours (days) capacity = way * days *24*60*60* stream /8/1024/1024.

Front end camera

The front end of the use of the camera are network cameras, equipment selection, depending on the specific installation location environment. The general selection principle should be:

Super class chain

Underground parking garage: a tube camera with infrared function.

Main entrance: a dome camera with a dynamic function of bandwidth and a gun type camera.

Each fire channel: the use of low light gun camera.

The larger the area: the indoor and outdoor PTZ camera.

Service desk: the use of dome camera.

The cash register channel: the use of gun camera.

The shelf channel and the sale area: the use of gun camera.

Chain store chain

Entrance to the store: the use of dome camera.

The central stores: choose 300 or 6 million CMOS ICR fisheye panorama network camera, day and night.

Cash register: dome camera.

Headquarters management platform to build

Headquarters management platform is the core of the chain stores, but also the distribution of the whole country in the shop to supervise the situation of effective tools, the management platform is generally built in the headquarters of the Brand Company. According to the different needs of the company, we put forward two kinds of construction plan.

Program A, you can access the authorized by the staff, to achieve the distribution of different access rights across the country. The system architecture diagram is as follows:

Plan B, by authorized personnel access, to realize the distribution in different operating stores across the country access permissions; and in the interior of the headquarters building a set of marketing teaching system, the Headquarters sales director, sales training supervisor can use the platform of the regional steering combat training, the system can be through the iPad direct control display wall, convenient teaching staff of flexible manipulators. The system architecture diagram is as follows:

The above two kinds of construction programs are able to achieve remote shop inspection; remote online video information intelligent retrieval, playback, save; online display function.

System to support the mobile client, access to authorized equipment resources; support through the deployment of electronic maps in the system, in a graphical way to view the state of authorized devices and resources.
User value

Remote store inspections by self built shop broadband Internet, can be directly on the computer of the monitoring center to see the shop scene image, the monitoring center of the monitoring computer through the forward end shop network camera, dome camera sends out the control command, the whole camera lens focal length or PTZ control were performed to observe the local details, to the shop for remote real-time sampling monitoring. In the supervision of the shop is standardized operating at the same time, but also to ensure that buyers business in the shop is normal and safe trading, and to provide the basis for punishment in violation of the provisions.

The local video store in accordance with the requirements of the company and business, save a certain time period of local surveillance video data, so as to company and after the occurrence of business store manager provides emergency accident analysis of effective basis.
