It is well known that Nanjing Yuantuo Technology’s embedded hard disk video recorder is widely used in the financial industry to monitor. The scope of application mainly includes bank branch teller monitoring, self-service bank monitoring, ATM monitoring, and treasury monitoring, etc. Recently, with the development of urban security monitoring work, and the need for multi-dimensional and three-dimensional combat and prevention of various financial crimes, as well as the acceleration of the digitization and networking of the entire industry, the gradual maturity of embedded technology and the rapid spread of computer networks , The way of unified remote monitoring and management of the existing bank video monitoring system is gradually realized and applied.
After years of exploration in the monitoring field, Nanjing Yuantuo Technology Co., Ltd. independently developed an embedded hardware platform based on H.264 image compression technology and a network multimedia centralized monitoring system to provide financial customers with office buildings, business outlets, self-service banks, and ATM terminals. , Treasury and other complete digital and networked overall solutions for security monitoring. This article will take the network monitoring system project of a branch of the Agricultural Bank of China as an example to discuss the design ideas of embedded DVR monitoring applications and solutions in the financial system.
The rapid growth of business has led to higher demand for security. After years of development, the branch of Agricultural Bank of China in a certain city has continuously expanded its business volume. Branches under jurisdiction at all levels, unmanned self-service banks and ATM systems have reduced the work intensity of staff and Improved work efficiency. However, with the deepening of the reform of the Agricultural Bank of China, higher requirements have been placed on the internal control and management of various functions of the branches. At the same time, how to better protect business outlets, sub-branches, self-service banks, and off-bank The safe operation of the ATM system also puts forward stricter requirements on the bank’s security system.
The Agricultural Bank of China has a total of 46 business outlets in the city, 18 off-line ATM systems, 4 branches and a vault. The number of outlets that need to be monitored is about 600 channels of audio and video, and a monitoring command center is set up in the branch office building. It is required to realize the management of audio and video signals of all outlets. To realize the linkage notification, management and processing of alarm signals, the branch center requires double backup of important audio and video data. Based on this, the plan proposes to use branch as the network hub of the entire system, branch lines as secondary network nodes, and business outlets, branch offices, and self-service banks as tertiary network nodes to establish a safe, efficient, and advanced remote security network Management system.
How to realize the networked monitoring needs of the financial industry
According to the specific monitoring needs of the Agricultural Bank of China in a certain city branch, combined with the original monitoring equipment of the business outlets, Nanjing Yuantuo Technology Co., Ltd. provided the design ideas for the network monitoring program of the Agricultural Bank of China in a certain city. In this plan, each district and county branch acts as a secondary center to realize centralized monitoring and management of the digital image monitoring system and alarm system of business outlets, self-service banks, and ATM machines that were originally dispersed locally. Led by the municipal branch science and technology management department, establish a city-level three-level branch network monitoring center to realize the management of digital video monitoring systems for branches and branches, self-service banks, and local treasuries. The distribution of authority of all users and the scope of jurisdiction are all managed by branches, so as to achieve the purpose of centralized monitoring and management.
The monitoring equipment involved in the plan is the HRC-168-ATM-DBR series embedded host of Nanjing Yuantuo Technology, which adopts advanced H.264 video signal codec technology, G.722 audio codec standard, 10 inch The high-definition digital LCD screen is integrated, the internationally popular embedded operating system, and the reasonable hardware architecture: it has the advantages of high stability, convenient operation, free from virus intrusion, and clear network transmission image quality. The following briefly introduces the design ideas of the program.
1. The focus of network monitoring on playback image quality
Bank business outlets are more important for transaction process monitoring, which requires relatively high definition of video playback image quality. Nanjing Yuantuo Technology HRC-168-ATM-DBR series high-definition embedded hard disk video recorders are used in the plan design to realize the transaction monitoring of the outlets , It can realize high-quality picture quality and voice functions, clearly monitor the daily receipt and payment operation of tellers, voice communication with customers, currency counting actions and face value, customer facial features and other data, and use video file recording management functions Video and audio recording files stored under different conditions, such as errors and accidents, can be analyzed and processed through the powerful search function to query and replay the recordings to avoid problems and disputes between bank counters and customers.
2. Self-service banking requires that when problems arise, relevant information can be inquired afterwards
Since self-service banking is a 24-hour self-service equipment video surveillance, when depositors are required to use the CDM, ATM and other terminal equipment installed in the self-service bank to deposit and withdraw money, if there is a dispute that the cash outlet does not issue cash, or the cardholder does not withdraw cash, they can Provide complete and clear video records for proof, so Nanjing Yuantuo Technology HRC-168-ATM-DBR series audio and video embedded hard disk recorders are selected. The host has functions such as ATM transaction card number superimposition and alarm linkage. When criminals use counterfeit, When the modified bank card is used for illegal deposit and withdrawal and transfer operations on the ATM, the host system can record the cardholder’s characteristics and store it on the local hard disk, and notify the branch and branch management center in time to provide evidence for the public security organs afterwards.
3. On-site safety issues of off-line ATMs
Compared with financial outlets, off-line ATMs are more scattered, and the on-site situation is more complicated. The ATM teller machine has a small space. Therefore, in the design of the plan, a dedicated embedded host for ATM monitoring of Yuantuo Technology is selected. The host has a lightweight and 10 Inch LCD display can be directly installed inside the ATM. The alarm function of the host can be linked with vibration detectors or glass break alarms. When criminals maliciously destroy, beat, cut, and excavate the ATM equipment During the behavior, the system can promptly detect and automatically call the police, and record the criminal’s voice, appearance and other clues to solve the case, and provide it to the public security agency as a basis for solving the case.
4. Jurisdiction of sub-branch monitoring center
The sub-branch monitoring center is responsible for the audio and video monitoring and alarm processing of business outlets, self-service banks, and off-bank ATMs within its jurisdiction, as well as the collection and management of all audio and video signals. Tiandi Weiye’s embedded digital video is selected in the plan Central Management System” to achieve the above functions. The host can not only realize the remote management of the audio and video signals of the outlets, but also integrate the integration of other security monitoring systems within the bank. In addition to the integration of the original 110 alarm system that has been built, it pays special attention to The construction and integration of various access control management systems, including the two-door interactive interlocking access control management system of business outlets, the access control management system of off-line ATM equipment, the access control management system of self-service equipment, etc. Through sub-branches, remote control of the access control system of self-service banking outlets, access control management after alarm, and remote audio and video intercom functions for self-service banking can be realized.
5. Centralized authority management of branch management center
The function of the branch monitoring center is to conduct unified management of the following four branches and to monitor the business outlets, self-service banks, treasury and office areas within the scope of the branch. For local monitoring, Nanjing Yuantuo Technology HRC-168-ATM-DBR embedded host is used to realize audio and video monitoring of business outlets, self-service banks, vaults and office areas. The branch monitoring and management center is equipped with three server subsystems: “user authority verification server”, “streaming media forwarding server” and “distributed storage server”. Among them, the “User Authority Verification Server” is designed based on the Web2.0 standard, which can realize the unified identity authentication and authority control management of all users in the system, realize the centralized configuration and maintenance management of equipment, alarm processing rule management, electronic map centralized configuration management, and equipment Functions such as patrol inspection and log management reduce the work pressure of the management staff of the branch monitoring center and improve work efficiency. The main function of “Streaming Media Forwarding Server” is to manage the streaming media forwarding management and on-site streaming media bandwidth limit management for multiple clients of the monitoring center to reuse the same live image. The limiting management strategy includes the number of channels, user priority and event priority, etc. , On the one hand, it uses the existing network bandwidth inside the bank to realize multi-channel audio and video signal transmission. On the other hand, it can reduce the bank’s investment in network links. “Distributed storage server” is mainly used in a centralized storage environment to implement high-reliability centralized storage, backup, retrieval and playback management of images in accordance with the plans and strategies set by the management center software to realize the management of the vault, voucher room, and safe deposit box. Double backup of audio and video signals of important internal network points such as the library, internal computer room, guard duty room, equipment operation room, financial room, etc., to avoid the problem of important data loss.
6. How to solve existing network problems
How to ensure that the monitoring screen between the branch monitoring center and the outlets can be clearer and more consistent, and does not affect the normal data business of the bank, which is the focus of the design of this program. In this program, corresponding solutions are designed for different network environments:
a. Transmission is carried out through the bank’s existing business data lines. For low bandwidth, “dual stream” compression can be used for transmission, which guarantees the quality of the front-end video and the effect of remote video.
b. Transmission through ADSL lines. As the cost of ADSL across the country is much lower than the cost of leased lines, the ADSL line and the center are connected to the network points that cannot achieve dedicated line transmission.
c. For outlets with low network bandwidth and need to transmit multiple channels of video, the function can be realized by using “streaming media forwarding server”. On the one hand, it improves the efficiency of response access, and on the other hand, it uses less time cost in exchange for more functions. High bandwidth utilization, thus solving the problem of low bandwidth.
Concluding remarks
The networked monitoring system for a branch of the Agricultural Bank of China, which was transformed by Yuantuo’s technology, was officially completed and put into use in 2008, and it has been running without any problems for more than a year. The construction of this financial networking system has played a due role in promoting the city’s economic construction, and also laid a solid foundation for the next step of connecting to the “3111 Safe City Monitoring Platform” for networking.
