1.Description of requirements  
Digital image monitoring system is a high-tech product that uses advanced digital image technology and computer image processing technology. It is a replacement product of analog image monitoring system. Digital image surveillance systems are not only fully compatible with analog image systems, but also add many new features.  
The use of a digital image system will greatly improve the use of the monitoring system, enhance the role of the monitoring system in event tracing and security prevention, and greatly facilitate the use of the monitoring system, reducing maintenance costs and use costs. In addition, after adopting digital image technology, the bank can use the existing internal network to implement remote image monitoring, security monitoring and management, which is suitable for the numerous business outlets and increasing self-service outlets in the banking system.
2. System introduction <br /> According to the demand analysis, the digital image monitoring system of the banking business hall is composed as follows:  
1) Front-end monitoring workstation system  
2) Central master control system  
3) The monitoring server system adopts Xunfei digital network multi-level monitoring system as its core technology platform, and realizes various functions of the system by integrating image, security, anti-theft, network and other equipment.
All front-end camera signals are connected to the monitoring station separately as shown in the schematic diagram.  
All the door magnetic switches, infrared probes and help buttons are connected to the image monitoring workstation. Through the processing of the input / output interface board, the alarm signals can be converted into digital signals to complete the signal collection and transmission. The monitoring station can process and send these alarm signals to the monitoring center, and perform alarm display, recording and alarm linkage recording.  
The alarm host is installed in the branch, but the alarm host does not provide alarm signal output. Therefore, an alarm linkage module needs to be added. All alarm signals are distributed through this module, one to the alarm host and one to the alarm input of the monitoring station. / Output interface board.  
The digital image monitoring workstation uses Xunfei XtreamProducer series XF100X monitoring workstations. Due to the powerful data processing and system integration capabilities of the system, digital image monitoring acquisition, compression, storage, transmission, anti-theft alarm monitoring and management can be completed on a software platform , Remote control and other functions, thereby reducing the cost of the system, improving the efficiency of monitoring and maintenance and reducing the difficulty of use.  
The built-in image compression card of the workstation can efficiently compress and process the connected images. Real-time dynamic monitoring of all images can be achieved through a computer monitor. At the same time, the system can call the historical data stored in the hard disk. This system uses the industry's top compression Technology MPEG-4 algorithm, the compression ratio is up to 1: 500, each channel only needs 60 ~ 120M hard disk space (including video and audio), and the bandwidth required for network transmission is adjustable from 64K to 512K. In addition, it realizes the automatic disk space dynamic detection function. When the image is moving, it will be recorded, if it is not, it will not be recorded or slow recording.  
In addition, the system can also flexibly set the linkage relationship between the alarm signal and the image. When an alarm occurs in the system, the corresponding camera recording and alarm output functions can be started by setting in advance. At the same time, the control center can also get alarm signals at the same time, and can perform real-time monitoring and observation through remote control.  
Set up the master control workstation and monitoring server in the monitoring center. The main control workstation adopts XF200X from XtreamController series. It can monitor any multi-channel video and audio of the 16-channel monitoring front-end with the same screen. The front-end PTZ and lens can be controlled by authorization. The main control workstation, the main control workstation will notify the management staff by means of sound, light and text; the main control workstation can also perform audio and video interaction with multiple front-end interaction points, and the leader can give orders to the front-end staff.  
The monitoring server provides hierarchical management of front-end monitoring workstations and hierarchical authority management of users; users can store front-end audio and video data on the central server in real time through the network as required; the server database records all video material information (video files can be It is distributed in various monitoring workstations or servers), alarm information, monitoring point information, and other data information. General users log in to the server through the WEB and can query any authorized information on the unified interface; for front-end (sub-branch) and center (branch) ) In a network environment that does not support multicast, the server provides unicast to multicast data forwarding, so that multiple personnel in the center can view the front-end real-time stream to save a lot of bandwidth.  
3. System implementation strategy <br /> Banking is a fast-developing industry, and the number of outlets will increase significantly within a few years. In order to adapt to this trend, it is necessary to carry out overall planning during construction, scientifically analyze the needs of the entire monitoring and networking work with a development perspective, and the branch monitoring center strives for one step, so as not to cause insufficient equipment configuration and capacity of the central monitoring room, which cannot adapt to the outlet Growth and continuous transformation, forming a waste of investment and disjointed management; while branches or self-service banks can adopt the principle of step-by-step implementation, build a branch, the previous system, and connect to the branch monitoring center, so that the bank can be guaranteed The monitoring system is developing healthily and orderly.
