With the continuous development of the financial security industry, the demand for financial security is also increasing. As an important part of financial security, video has undoubtedly become a beachfront position for many manufacturers to compete for, and various manufacturers have also launched financial targets. The industry's high-definition solutions, in which network HD cameras and broadcast HD SDI are currently the two mainstream HD solutions.

Network HD VS Broadcast HD
Network HD cameras, known as cameras that transmit audio, video, and control signals over a network, have the advantages of high resolution, transmission distance, and transmission medium. And can provide a variety of functional customization according to user needs. For example, in the financial industry, corridor image mode, digital banknote overlay, adjustable area image quality, front-end intelligent analysis, image deformation correction, attention area code stream and many other special application functions to meet the needs of users in different areas. In addition, the author believes that due to the introduction of IT technology, the network high-definition ALL-IN-ONE is also a very big bright spot, which greatly saves the cost of auxiliary materials, making integrated wiring cheaper and more efficient.
The broadcast high-definition endorsement is SDI, which is popularly digital uncompressed technology, which is the standard promoted by the HD cctv alliance. Because it uses uncompressed technology and has an ultra-low latency advantage that is undetectable by the naked eye, it provides high-definition video with a resolution of 1080P while retaining all the details of the video to the utmost extent. The delay of the control is almost the same as that of the traditional analog system. At the same time, due to the advantages of SDI structure, front-end cameras tend to be very stable.
High-definition monitoring needs to be solved in the financial industry
High-definition monitoring in the financial industry applications to solve the problem from the network HD and broadcast HD implementation, it is not difficult to see that all manufacturers in the high-definition solution have made a lot of effort. Acquisition, transmission, and storage all ensure high definition, but in combination with the specific status of the financial system, it is only to meet full HD, there are still many problems. According to our past experience, combined with the actual application of customers, the following points are summarized:
· Low-bandwidth transmission of high-definition video, financial security network construction Currently, the network bandwidth is still seriously insufficient. The bandwidth from the branch to the branch is basically 2M-4M, and the bandwidth from the branch to the provincial line is basically 4M-8M. Today, in the Internet of Things era, financial security The big network has become an inevitable trend. However, the high-definition solutions introduced by various manufacturers often do not consider the big network of customers. In the current bandwidth of the financial system, only a few channels of video can be transmitted, which obviously cannot meet the centralized management of users. Demand
· Long-term video storage, according to the requirements of “Bank Business Site Risk Level and Protection Levelâ€, the level of bank business site security protection is divided into three levels, from low to high: three-level protection, two-level protection, one level Protection. Video recording is an important evidence for the bank. The general video storage time is 3 months, the important video storage time is 6 months, and the treasury and other storage time is longer. In today's high-definition program, data storage has become a troubled solution. The challenges of providers and customers, especially digital uncompressed storage, are even more stretched;
· Data redundancy. When using the embedded DVR, the video is lost due to the damage of the hard disk. The supplier is exempt from liability. Many users have feedback with us. In view of the development of technology, the era of IT and security to achieve a win-win situation has arrived, we can achieve data redundancy protection through servers and array cabinets, and through effective means of management, everything is very easy;
· The connection between equipment and networking platforms is particularly important in the era of large networks, especially large-scale networking projects at the provincial level and above. After analysis, we generally found that the communication protocol of the device and the software development kit (SDK) have design flaws, mainly because the domestic manufacturers pay too much attention to the function development of the device itself, and ignore the supporting networking protocol and SDK interface standardization. , resulting in various unpredictable and difficult to repair functional defects in the large-scale networking process.
A bank's high-definition video networking project in Hainan Province involves 200 service outlets, 3,000 HD network cameras, 200 NVR servers, and a massive HD storage project with a total capacity of 4800T. As the first provincial-level networking project in national finance, this is a good start to shoulder severe challenges, and it also lays an indelible foundation for the comprehensive promotion of the financial Internet of Things in the future.
How to provide solutions that meet user needs
In order to solve the difficulties that HD solutions currently encounter in financial security, we must first understand what the financial security customers need for HD, and then combine existing technologies to provide users with a truly practical and high return on investment solution. Program.
Financial security users can be divided into two major parts: commercial banks and state-owned banks. The requirements for high-definition applications are mainly reflected in the monitoring, business supervision and post-supervision audit of key prevention areas. The key prevention areas in commercial banks mainly refer to the treasury and important channels. The People's Bank mainly refers to key libraries and bullet management centers. The high-definition demand of commercial banks in business supervision and post-supervised auditing is mainly reflected in the supervision of the tellers' business and the supervision of the cash-filled business. In the business supervision and post-supervision audit of the People's Bank of China, the main manifestation is the supervision of the central business of the banknotes.
Based on the needs of users, we will come back to see HD solutions. It is not difficult to find that financial security is not blindly pursuing full-frame HD, but to achieve key areas or limited global HD in limited bandwidth, so the device should consider using High. The profile encoding method and the adjustable image quality of the specified area really help the user to relieve the pressure of network transmission and video storage.
With the rapid development of security technology, HD video solutions have been more and more accepted by customers, but some manufacturers do not combine user needs and status quo, in order to obtain high profits and blindly guide customers to buy high-end equipment, resulting in huge investment after users It does not achieve the expected results, but also causes difficulties for the big network. If we want to "push", we must stand on the user's point of view, analyze the potential needs and actual functions of users, where to use high-definition, and then combine the existing technology to "push" the program, to be a guide for high-definition financial Internet of Things. .
