2. Overall structure of the system

HD video network system of Bank adopts unified architecture; the overall structure should meet the need of high-definition image acquisition from the front end, real-time and reliable transmission of data flow and network security of the whole system. Overall logical structure system is divided into four layers from top to bottom: monitoring layer, data transmission layer, data processing layer and business application layer.

1. Monitoring layer: The monitoring equipments mainly include front end IPC, voice intercom, intrusion detectors, alarms, access control and other necessary hardware facilities for data acquisition, the main function of these devices is to collect and send the information which considered by security persons including videos, audios, alarm signals and environment conditions to the background constitution for processing and responding to the remote control in the background management center at the same time.

2. Data transmission layer: the transmission layer can set the light signal transmission system, IP digital image information system and the traditional analog information system at an organic whole, and is able to complete transmission of transparency of businesses like video, audio, data and telephone etc. And effectively perform integral business insertion; realize the insertions and data exchange of many businesses on one platform.

 3. Data processing layer: Main equipments on data processing layer include management server, the alarm server, streaming media server, storage, decoding server, appendix server, TV wall server, TV wall, and customer terminal workstation which is needed in the process of the multiple work. Their roles are handling various data (control, video, audio, alarm, etc.) sent from the front-end, filter and organize data according to the predetermined scheme, and finally present in the forms which are easily accepted and operated by monitors.

4. Business application layer: business application layer mainly realize various digital applications of video information. Including GIS systems integration, entrance guard system, perimeter prevention alarm, fire control integration, video previewing, video playback, intelligent video analysis, video decoding on wall display, system management and remote maintenance, system integration business, etc.
