Perspectives on the development trend of video surveillance in public safety and finance

Perspectives on the development trend of video surveillance in public safety and finance In recent years, the domestic security industry has made great progress. The international anti-terrorism situation, western development and rejuvenation in the northeast, the 2008 Olympics and the Shanghai World Expo, domestic urbanization and rapid urban construction, the construction of safe cities, and the frequent occurrence of security accidents in some application fields constitute the main positive factors for the development of the security industry.

As the core part of the security system, the development of video surveillance technology has experienced analog surveillance and digital surveillance are being developed to large-scale network surveillance. The various components of the video security monitoring system - front-end video capture, video transmission, video recording, alarm recording, control, and display technologies are developing rapidly.

The development trend of the video surveillance platform is distributed collection centralized management, high-quality image compression processing, open standard unified interface, unified authentication to ensure security, humanization of operation, and function integration, structural modularization, and transmission diversity.

The overall development trend of security systems in 2012 is: high-definition, intelligence, application, and integration. However, each industry may have its own industry characteristics. Following the author and everyone together to discuss the public security and financial security development trends.

In the field of public safety, in October 2005, the Ministry of Public Security deployed the pilot project for the construction of the national urban alarm and monitoring system (ie, the “3111” pilot project), and identified 22 cities as ministerial-level pilot cities, determined by provinces, cities, and autonomous regions across the country. More than 400 pilot counties, cities and districts. In 2010, major cities in the country have basically completed the construction of urban alarm and monitoring systems.

In 2011, Safe City entered the overall promotion stage and was promoted to each prefecture-level city. The total direct investment was nearly 100 billion yuan. In the next five years, major cities in China will continue to invest huge sums of money to fully develop the city's alarm monitoring network. According to the estimates of the Ministry of Public Security’s Science and Technology Bureau, the investment in the construction of a safe city in a medium-sized city will reach several billion, of which the proportion of video surveillance systems is 28%, and investment in storage equipment will often account for 20% of the total investment in video surveillance equipment. ~40%, with the development of high-definition video surveillance, the demand for storage devices will increase directly to several times or more than a dozen times. At present, there are more than 2,300 cities and counties in China, which have great market potential.

With the continuous deepening of the application of the alarm and video surveillance system construction and application, the top priority in the construction of safe cities - the security technology prevention system has become an important means of public security prevention and an important part of the construction of social security prevention and control system. Preventing, detecting, controlling, and cracking down on illegal crimes, providing clues for detecting crimes, fixing evidence of crimes and crimes, and other aspects play an important role that cannot be replaced by human defense and physical defense.

The public security department is the most powerful organization for the construction of a safe city, but at present the public security department faces many difficulties in the process of building a safe city. First, the construction of a safe city lacks organic integration in the business, and the construction of a video surveillance system is self-contained. Integration and repeated construction are serious. At the same time, each system has a small coverage and narrow application. Secondly, existing video surveillance systems lack efficient integration with emergency response and policing services. Video utilization is not high, system integration is insufficient, and there is no completeness. The integration of video, bayonet, and alarm systems has serious problem of information islands. Although there are huge data resources, these data have not been effectively used. Generally speaking, the information generated by these systems and equipment is lacking. Deep application and comprehensive application.

At the same time, the birth of network monitoring solves the traditional monitoring effect, changes the traditional connection method, and is simpler and more convenient, but at the same time, it leads to more huge storage requirements and higher bandwidth satisfaction, taking the most basic 720P effect as For example, each video compression to a lower bit rate also requires 3G capacity per hour. One month monitoring video requires about 2TB of capacity. So imagine if you need hundreds of thousands of such high-definition surveillance, such a huge video The documents, like a tidal wave, impact the storage system, which not only imposes higher requirements on the storage device capacity, read/write performance, and reliability.

Whether playback can support such a large amount of information is also a problem. At the same time, the security requirements for stored HD video are also high. From the huge amount of high-definition video that is saved, how to retrieve and recall images for image analysis is also a challenge.

Fortunately, with the acceleration of technology updates, the popularity of high-definition devices in 2012 will become the trend of the video surveillance industry. Although the past two years have also been improving the cleaning equipment, there has been no case of extensive use. The good network bandwidth of the public security industry gave HD video technology a high-quality display stage. Problems such as lack of definition, low intelligence recognition rate, and transmission and sharing capabilities can all be well resolved. Therefore, it can be seen that more and more safe city projects use high-definition equipment as a pilot operation. Another problem that is associated with high-definition devices is storage. In addition to the storage pressure mentioned above, in addition to the traditional storage performance improvements such as DAS, NAS, and IPSAN, the concept of cloud storage is also proposed. It can target massive amounts of video data. High-speed and effective retrieval of high-definition video data.

By the deadline, all provinces have basically established centralized networking platforms for provinces, cities and counties. How to apply these data to public security operations in the future? How can we help police quickly detect cases? It will be a new challenge for the construction of safe cities. challenge.

The financial sector in the financial sector is also a focus of security work, including banking, postal services, and securities. As an important daily work in the financial industry, security guarding is of great importance to the normal operation of the enterprise and achieving good economic and social benefits. The implementation and implementation of security protection in the financial industry is an important foundation for the development of the financial industry. one.

Remote centralized monitoring is a manifestation of the networked development trend of the security industry in recent years. Through remote centralized monitoring, it can effectively improve the ability and efficiency of on-site monitoring of important sites, and plays an important role in ensuring the production safety of enterprises and promoting the stable and sustainable development of enterprises.

Taking a provincial-level financial institution as an example, the ultimate goal of construction is to use professional monitoring and networking software combined with digital monitoring technology to implement centralized remote monitoring of decentralized business outlets and production departments. For the production, treasury and business premises under the jurisdiction of cities, counties, and districts, the need for unified remote centralized monitoring and control is realized, and the monitoring video resources of various cities can be concentrated on provincial platforms for access and invocation.

But now there are still many problems:

Regional deployment is the main, and the degree of networking is not high At present, business outlets and ATM self-service banks are basically equipped with traditional video surveillance systems. However, the traditional digital-analog monitoring system is usually based on local monitoring and local storage. That is, each of the network points establishes a complete monitoring system. The lack of monitoring information between the network and the parent organization is an organic link. Although this basically completed the main functions of the security monitoring system, due to the lack of a unified planning and a unified design, the systems are independent of each other and cannot be effectively supplemented, resulting in passive security work and difficult management. There is no way to share information such as surveillance images and anti-theft alarms between outlets and higher authorities. Once a network emerges from an emergency, higher authorities cannot fully grasp the situation in a timely manner.

The system design standards are not unified. The long-term lack of unified standards for compliance in the financial security field, and the time for system construction are not long enough, resulting in the existing business network monitoring systems in the technical system, equipment selection, product brands, agreements, etc. There are many differences. From the collection and transmission of front-end signals, to the exchange and control of central points, to the display and storage of back-end signals, there are certain differences in degrees, which is not conducive to the realization of unified management, image networking, remote control and intelligent alarm. deal with.

The system basically belongs to the passive monitoring, and the intelligent program is not high. The local monitoring system or the network monitoring system built in each network point can not really get rid of the limitations of passive monitoring. There are still many problems in the use of the human factors in the system.

Such as whether the staff on duty can normally use the equipment and software, whether it can use the system to actively monitor the system according to the regulations, take the initiative to deal with problems, and whether they can actively search or record. The existing video system and alarm system are not highly integrated and the system is not intelligent enough for use with the system. For example, when a subordinate has a police report, the superior handler usually needs to manually open the live image, find the location of the alarm, the person in charge, contact information, make an artificial call, and deploy the police force.

Inadequate internal control supervision, counter-terrorist operations are not standardized At present, the work supervision and assessment methods for the tellers in the business office are mainly regular spot checks. There are many omissions in this supervision and inspection mechanism, which cannot guarantee real-time supervision, and cannot guarantee the existence of problems or hidden troubles. Time to give reminders and records. It is urgently necessary to further regulate the daily work of tellers through remote visual supervision and management and business assessment.

The external security precautions are not sounded and the response is not timely The ATM self-service bank has not yet fully unified centralized visualized networking, and cannot effectively implement remote intercom guidance, alarm upload, and intelligent alarm preplanning. Crimes against ATMs are relatively high. If ATMs are implemented with 24-hour remote real-time linkage monitoring and voice intercom alerts, they will effectively contain ATM crimes.

Although the security monitoring in the current business hall has basically reached the requirements for localized alarm deployment and linkage, the degree of intelligence is not enough. In addition, the alarm information cannot be centralized and reported to the superior, and it cannot be handled well with the 110 alarm center.

At present, the treasury generally maintains the library for the local two-mankeeper mode, and there are certain internal risks.

The transfer point of the armored car at each business network is a high security hidden trouble zone. However, the current escort management system has a certain regulatory blind spot for the management and handover process of the escort personnel. At the same time, there are abnormal circumstances and emergencies to the surrounding environment of the transfer point. The speed of response and other issues.

The financial industry is characterized by the diversification and complexity of the monitoring equipment used and the individualized requirements of security applications. It is an intelligent prevention and control digital system with high integration, external defense internal control, operational services and management supervision. Different from public security, the financial industry focuses on alarm information, such as ATM alarms, business network alarms, and vault alarms. The alarm volume of alarms is very large. Therefore, the alarm processing capability of security systems is a test. In addition, there are detailed classifications for the handling of alarms, including early warning, normal alarm, important alarm, and emergency alarm. For the handling of alarms, linkage of alarms (linked access control systems, linkage IP intercom systems, linkage video surveillance systems, etc.).

The financial industry has its own specialized business network. The early video surveillance systems used the business network sharing model, making the financial industry only use low-resolution video in the CIF format due to the limitation of network bandwidth. The monitoring center only serves as a real-time preview of the screen. Now that the financial institution's network has begun to gradually transform, but the network still can not be compared with the police's video private network, it is generally 4M-8M bandwidth, so the video surveillance system is required to have media distribution capabilities.

In view of the special network conditions in the financial industry, storage also has corresponding strategies. It adopts a centralized storage system for distributed storage and central alarm recording. The front end uses hard disk recorders such as DVRs or NVRs, and is equipped with industrial-grade hard disks that guarantee 30-day storage. The monitoring center is equipped with dedicated storage servers and disk arrays to back up important alarm videos. Time can be saved for up to six months or more. Long.

Different monitoring areas in the financial industry require some business customization features such as:

The daily monitoring services that will be involved in these places such as business halls and counters include: digital superposition of counter cash registers, statistics of people flow, analysis of abnormal behaviors of employees, and spot checks of working conditions of employees (wind construction);

More and more banks in the treasury are now using unattended treasuries, which requires the security platform to be able to maintain the library.

For video surveillance systems, access control systems, and technical anti-alarm systems, a complete solution is needed.

Self-service bank, departure ATM

The self-service bank will involve the analysis of abnormal behaviors: beats, installation of illegal stickers, installation of card readers, multi-face withdrawal; voice intercom at the time of the case, monitoring center, deterrence, front-end alarm bell linkage, self-banking access control Wait.

Monitoring center staff's handover management, risk event management, multi-level alarm management, GPS electronic maps and other linkage management.

It can be found that the financial security monitoring platform adopts advanced data monitoring technology, software technology, multimedia technology and network communication technology, and fully integrates the financial system business applications. It is stable, reliable, safe and covers all outlets and various self-service banks, vaults and other key points. Site monitoring system.

In the concluding remarks, the two major industries of public security and finance were mentioned. Of course, security has achieved rapid development in various fields, such as education, communications, and energy industries. I would like to take this opportunity to discuss with you the next development of the security industry will have how the development of security monitoring system platform will be how to change, and hope to witness the 2012 Chinese security boom.
