After several decades of development, the field of security monitoring has been fruitful. Whether it is a front-end high-definition camera that enables a qualitative leap in video quality, or a breakthrough in the amount of information that the back-end cloud storage is about to bring, it not only allows video surveillance systems. In the area of ​​social and public security, it has become popular, and it has also given rise to growing video surveillance information such as rivers and rivers. Time and space that hastily disappeared and changed is preserved in massive video surveillance information, but these have consumed a lot of human, material, and financial resources, and have been able to maintain public security, combat illegal crimes, ensure the safety of life and property, and promote the normal use of applications. How much benefit does the operation bring? In fact, this question is triggered by thinking about how to tap the maximum value of video surveillance information. The third joint conference on regional policing of the public security organs of three provinces and one city in Jiangsu, Zhejiang and Shanghai was held in Nanjing on April 28. The public security video and video information in the four places will be gradually shared, and the parties in charge will sign applications for this purpose. Cooperation Framework Agreement. Therefore, it is of great significance to implement efficient management of video surveillance information; reasonable application of video surveillance information is worth studying.

Based on the background of China's social and public security development and the growing strength of security monitoring, the reporter invited industry insiders and experts concerned about the development of China's public security and security monitoring industry - China Telecom Research Institute Shanghai Research Institute Liang Shuguo , Guangzhou Aoqi Man Electronic Technology Co., Ltd. Hu Anjun, Tongji University School of Transportation Engineering Fu Yihong, Hunan Institute of Industry and Business Administration Ouyang Aihui discusses the management and application of video surveillance information.

Great importance is attached to the management and application of video surveillance information. Liang Shuguo: With the advancement of Pingan City and other projects, surveillance cameras have spread all over the streets, which left image data for most cases and brought great convenience to the police. . At present, there are about 20 million cameras in our country, and about 3 million are used in Safe City. The vast majority are based on district and county public security bureaus.

In addition, we are now pursuing high-definition images, and the overall amount of information and data has increased dramatically. Therefore, investment in systems is increasing. In fact, a large amount of video information is useless, and the actual effect may not be more than 1%. The monitoring system that our country has invested a lot of money in is not very effective.

The so-called security video management, I believe that the security video surveillance system in the city or the provincial network, and real-time video surveillance and a large number of video recording data for comprehensive management and analysis, to dig out more valuable information for Society has a greater role to play: After networking and intelligent analysis of video, it can greatly improve the use of real-time video and video data and improve the efficiency of detection. Through cross-regional (or even cross-city) multi-camera video data linkage analysis, Get some in-depth clues that are difficult to obtain under a single surveillance system; through the opening of video recordings and real-time video (under the premise of ensuring information security), to other departments, such as transportation departments, civil affairs departments, and public users, the largest To play the benefits of a huge investment system.

Hu Jun: With the development of the monitoring system, various areas of people's daily life are gradually building up and distributing a wide range of monitoring points. Faced with massive amounts of video surveillance information, borrowing from ever-increasing computer and network technologies, these resources can be applied maximally.

First of all, intelligent search can quickly find the necessary information in a large amount of video information.

With the development of computer technology, monitoring has gradually evolved from the original analog video system to a digital monitoring system, which provides a solid foundation for the intelligent application of monitoring information. At present, many high-tech industries have emerged in the industry, such as: motion detection, alarm triggering, face recognition, and so on. Its fundamental purpose is to search for massive video surveillance information in the fastest and most effective way. The information we want.

Secondly, video resource sharing makes the same video signal applied in many fields.

The construction of each monitoring point is usually based on the needs of a certain area, but often the information of a certain monitoring point can have great application value in many aspects.

For example, a monitoring point of a classroom can play a role in theft prevention, examination tour, video teaching interaction, etc.; a monitoring point on the road can play a role in “safe cities” and traffic management.

Sharing of video resources can greatly reduce the waste of resources and maximize the effectiveness of each video resource.
