Video technology has taken the construction of a safe city to a new level, making a city's security and prevention management system more intelligent. Urban security has evolved from a flat defense system in the past to a three-dimensional security system. Provided a dynamic information collection and command system for Ping An City. The widespread application of video technology has also led to the evolution of Ping An City from a simple security protection system in the past to a comprehensive urban system. The Ping An City project covers many fields of society, and the introduction of video technology can establish comprehensive three-dimensional protection through wireless mobility, tracking and positioning methods. A comprehensive system that takes into account the overall urban management system, environmental monitoring system, traffic management system, emergency command system, and other applications.
 
From the future development trend of Ping An City, video technology will have the following application changes:

Expanding from traditional security applications to business applications
 
With the deepening construction of Ping An City, video surveillance has entered four new stages of application: comprehensive application, deep application, emergency application, and social application. Among them, comprehensive application refers to the application of all types of police, including public security, criminal investigation, and patrol; Social applications serve social management, and the digital resources of video surveillance provide innovative services for government social management, providing important support in administrative services. Deep application mainly lies in deep data mining, which analyzes data through numbers to understand some new social trends. Emergency applications are mainly reflected in emergency response to emergencies, large-scale security work, such as the application of communication support in large-scale events such as football matches, concerts, and Olympic Games.
 
Intelligent analysis applications are driving video surveillance from security devices to visual sensors. As an efficient, passive, and non-contact high-quality perception technology, video can penetrate into the smart business of various industries in the city beyond security applications and become a comprehensive source of perception information, thereby improving the real-time, diversity, and interactivity of comprehensive information in Ping'an City. It can also provide effective support for the real-time business development and historical big data mining in Ping'an City. At present, the development trend of video technology from mature security applications to safe city business applications is very obvious.

The development of single video information towards multi-source information fusion
 
The current surveillance camera equipment has a single purpose, but if they can be integrated with data from other sensors, it may solve many problems in urbanization construction. For example, by analyzing the correlation between data on traffic flow in camera equipment and data from air quality sensors, we may be able to optimize the waiting time of vehicles at intersections by adjusting the time of traffic lights.
 
The rapid development of the national economy and urbanization construction, the continuous acceleration of population mobility, and the rapid growth of urban population have led to related issues in urban management such as public health, public transportation, and public security. Among them, public security issues are of utmost importance, which are related to the safety and well-being of urban residents and the success or failure of building a harmonious society. Safe cities have emerged according to the situation. The Ping An City construction project, as a large-scale and highly comprehensive management information system, not only needs to meet many needs such as public security management, urban management, traffic management, emergency command, but also needs to consider multiple needs for image monitoring in disaster and accident warning, safety production monitoring, and other aspects. At the same time, it also needs to consider the integration of supporting systems such as alarm and access control, as well as the linkage with the broadcasting system. It is like a big net that comprehensively covers every corner of urban and rural areas, achieving safety goals through "automatic prevention in advance", "comprehensive monitoring during the process", and "rapid breakthrough after the fact".



The development of video surveillance towards "visualization"
 
The visualization of video surveillance refers to the realization of alarm positioning visualization, police force distribution visualization, police situation on-site visualization, and alarm process visualization. Through four visualizations, it realizes point-to-point and flat command and dispatch of street police forces, while supervising the law enforcement process and doing a good job in evidence collection.
 
By relying on the existing video application platform system, we can achieve synchronization between police situations and videos. For areas with monitoring conditions, we can achieve on-site monitoring, capturing, and evidence collection by ensuring that police forces do not arrive and videos arrive first. In addition, reasonable division of defense zones is required to ensure that the first batch of police forces arrive at the scene as quickly as possible.


 
Two Major Technologies Assist the Landing of Safe Cities
 
Building a Safe City Smart Brain with Big Data
 
At present, the construction of smart cities has been comprehensively promoted from key single field intelligent applications to comprehensive urban intelligent applications. The construction of basic network application facilities such as data centers, shared exchange platforms, and big data analysis platforms is also being accelerated. Most first and second tier cities have completed the construction of infrastructure for safe cities, and will now enter the stage of big network integration. Based on this integration, unified management, intelligent analysis, and application of video resources will be achieved, enabling intelligent analysis and prediction capabilities based on video big data, and ultimately promoting a truly safe city.
Supported by big data technology, the network video surveillance data storage model can shift towards a distributed data storage system, providing efficient, secure, and affordable storage methods. Through big data technology, it is possible to achieve fuzzy query, fast retrieval, precise positioning of video images, and further explore the value information behind massive video surveillance data. It can quickly provide feedback on connotation knowledge to assist decision-making and judgment, thus making video surveillance better and more effective.
Ultra high definition videos empower urban vision
As an important field of ultra-high definition applications, the security monitoring field will accelerate the research and development and mass production of ultra-high definition monitoring cameras in the next step. Promote the upgrading and transformation of security monitoring systems, support the development of artificial intelligence algorithms such as facial recognition, behavior recognition, and target classification based on ultra-high definition videos, improve monitoring range, recognition efficiency, and accuracy, and create a batch of intelligent ultra-high definition security monitoring applications, thereby promoting the construction of Ping'an City.
 
The new technologies and methods brought by big data to solve the problem of massive data are crucial for China's safe city construction to reach new heights. The key to the application of big data in the field of Ping An City lies in the combination of "IT" and "operation", that is, the efficient use of big data technology, the development and transformation of applications into business models, and the enhancement of Ping An City's construction, operation, and management capabilities. The integration of more and more emerging IT technologies will open up a broad development path for big data technology in the field of video surveillance.

"Ping An City" is a complex system engineering that works together with management systems to achieve the security and prevention goals of Ping An City design. Although Ping'an City has gone through many years of construction, its construction enthusiasm has been enduring. With the help of emerging technologies such as chips, algorithms, the Internet of Things, and big data, Ping An City is continuously injecting fresh blood and moving towards greater intelligence.
