High-definition surveillance adds to the smart city

At present, "high-definition" has become an inevitable trend in the development of the new safe city. The new safe city video surveillance system has been changed from the "visible" video security system to the "clear" high-definition networked system and follows the principle of "building for use, using for the war" and began to "see" The integration of intelligent and operational real-time system construction, research and development of video surveillance systems that meet the requirements of public security operations is a topic that must be met by manufacturers. Smart HD is also known as the highlight of smart city construction.

Different scenes need different high-definition and high-definition is not simply a kind of single high-definition technology applications, but from the actual business application needs of public security to start, can adapt to the city to control the demand for high-definition image quality. The entire city's control surface is in a complex and diverse application of the "ecological environment." Therefore, the construction of a high-definition, safe city system requires the selection of appropriate HD solutions based on the different characteristics of different application scenarios.

For social applications, the use of 700-line analog high-definition solutions to achieve 960H resolution, the program has both performance and price advantages, can effectively improve the social image quality.

For public security self-built sites, the use of megapixel IP high-definition solutions to achieve higher 720P, 1080P resolution, to achieve high-definition system deployment of key parts of the city.

For some important points, there are higher requirements for real-time performance and followability. HD-SDI HD solution is recommended to achieve 1080P lossless, no-delay, high-advanced HD system construction.

Smart city and high-definition surveillance are synchronized and upgraded. High-definition upgrade continues, and front-end intelligence is the next point of view. In the 12th year, China’s cameras shipped about 45 million units, with an output value of 50 billion yuan, of which high-definition products shipped about 4 million units, an increase of 85% year-on-year. We expect the high-definition penetration rate will increase from 10% to 40% in the next three years, with high growth expected. In the future, the bigger point of view lies in the intelligence of front-end products, including intelligent identification and intelligent analysis. The advantage of front-end analysis is that it has high real-time performance and can be linked to alarms. Transmission also eliminates useless information, which greatly reduces the burden of transmission and background storage. .

With the gradual opening of the industry and the civilian market, the demand for NVRs broke out. 13 years of high-definition applications are no longer limited to high-end government and industry sectors such as public security, transportation, and finance. With the further adjustment of HD IPC and NVR prices, products have extended from professional security to civil security, such as shops, residential houses, hotels, and office buildings. With the popularity of high-definition digital front-ends, the demand for back-end NVR storage will grow rapidly. In the 12 years of domestic NVR capacity of 430 million yuan, 13 years is expected to grow 90% to 820 million. Dahua, on the other hand, is expected to expand its mid- to low-end high-definition front-end market through channels this year, which is also a big surprise.

Intelligent HD or will become the highlight of smart city development For traditional surveillance, there is a big conflict between HD and smart. Compared with analog surveillance, the threshold for high-definition video surveillance technology is much higher. Such as auto focus, auto exposure, backlight compensation, electronic shutter, color auto-correction are all difficult to overcome technical difficulties. The increase in storage costs, display, and bandwidth all constrain the high-definition monitoring.

In the future development of intelligent security, how to break through the technical bottleneck of high-definition monitoring, and how to more comprehensively and compatiblely realize the intelligent work of surveillance cameras is the main issue to be considered by the market. Not only that, but the unification of industry standards and technical concepts is equally important. Intelligent HD can play the most important role in intelligent security work under the influence of these cohesive forces.

In today's urban planning, the construction of the complex has always been valued. It is precisely because the urban complex organizes at least three life functions in the city, including business, office, residence, catering, entertainment, transportation, etc., and establishes a kind of interdependent and interactive relationship among various departments, forming a multi-functional , efficient building community. Regardless of where the urban complex originated, it has become one of the weather vane of the city.

An excellent urban complex must be a smart urban complex. The wisdom of an urban complex includes many aspects. The first is the positioning of wisdom: Positioning will determine the function, customer, price, and brand image of a project. The scientificity of the overall plan is one of the decisive factors for the success or failure of the urban complex project. Not only is it coordinated with the external overall environment, including the layout of business functions and the spatial structure design, so investment promotion is also important; the third is management wisdom. For each city complex, the continued prosperity—whether it is one day or one hundred years of prosperity—is the only measure of success. How to carry out scientific management is a problem that complex managers must think about. Before the operation of each city complex, an independent and professional property management team must be formed, and mature partners should be introduced according to their needs to provide comprehensive services to the owners and consumers so as to ensure passenger flow.

If the urban complex relies heavily on manual operations, management, and monitoring, it will greatly reduce the operational efficiency and value of the complex. To achieve the full realization of the functions of urban complexes and the realization of smart operations and management, in addition to the concept of wisdom, it is also inseparable from the support of intelligent facilities, including intelligent lighting systems, intelligent control, information infrastructure, intelligent building equipment management systems, and intelligence. Security system and so on. Among them, the security issue is a top priority. Whether it is families, shopping malls, communities, or roads, etc., it is crucial to monitor all aspects of information in real time and respond to unexpected situations in a timely manner.
