With the development of networking and intelligence, The smart city based on the Internet of things architecture has stepped onto the stage and become the protagonist. Public security organs at all levels should focus on the in-depth application of video monitoring system technology and establish a multi-level video image information sharing platform that can be interconnected and controlled within the scope of authorization, so as to meet the needs of various departments for video image information, such as police types, intelligence research and judgment, command and communication, investigation and case solving, public security prevention and control, social management, anti-terrorism and riot prevention, stability maintenance and handling, and standardized law enforcement, Gradually build video surveillance technology into a new professional technology of public security organs. Security enterprises have accumulated rich experience in safe cities for many years, and smart cities also put forward higher technical requirements for video surveillance networking. Therefore, it has become a general trend of the security industry to focus on the development of urban networked monitoring system and actively participate in the construction of smart city!

Compatible and open
Taking Ping An City monitoring system as an example, the front-end equipment is distributed in every corner of the city such as roads, communities, shopping malls and schools. And the phenomenon of each system fighting its own war is very obvious. The video monitoring network system puts forward complex compatibility problems for the integrated management platform system. First, the front-end equipment manufacturers are different; Secondly, the management software used by each subsystem is different. The centralized management needs to be compatible with the equipment of various manufacturers and subsystem platforms.

Intelligent processing
The scale of the smart city monitoring system is gradually expanding. The growth of the number of videos and various data makes the limited manpower insufficient to manage such a huge system. The backward video processing capacity also increases the workload of system maintenance and use, such as automatically discovering suspicious behaviors and targets in a large number of real-time videos, Or find the vehicle with the specified license plate number from a large number of video images in a short time, or find fugitives and suspects in a large number of people. Users urgently need to assist in processing in an intelligent way.

Practical application
The construction of smart city system leaps from the original simple functions of video retrieval, management, storage and control to practical business applications. It is necessary to integrate and link the monitoring networking platform system, high-definition electronic police system, high-definition bayonet system, mobile vehicle / individual combat system and social monitoring resources with business application systems such as public security three in one system, emergency command system and PGIS system, so as to realize a comprehensive practical application management system.

Through the integration of HD bayonet / electronic police system and PGIS system, the unified management of video monitoring and bayonet control is realized. Through license plate recognition, the vehicle access records can be retrieved, and the car track can be drawn according to the query results to help public security users realize the control and pursuit of suspicious vehicles.
