From the perspective of the entire security industry, security mainly includes intelligent monitoring systems, anti-theft alarm systems, intelligent access control, building intercom systems, etc. Among them, video surveillance occupies half of the entire security market, accounting for 49%. From the perspective of market size and development, the intelligent improvement of existing security is the most important direction of the entire security field.

Before the advent of 5G, AI was hot, and there would be no security without AI. However, intelligent security is still constrained by low-quality, low-bandwidth, and low-speed network transmission systems. With the construction of smart cities, massive amounts of video surveillance data and IoT data are continuously produced, and existing communication technologies cannot meet the multi-node links and massive video transmission requirements required for security. From the beginning, 5G technology was defined as being developed for ultra-high speed, high reliability, and low latency. This series of characteristics just meets the demands of the development of a new generation of intelligent security. The combination of 5G and AI intelligent algorithm models makes the data accumulation process faster and faster, ultimately achieving real-time updates and scene optimization.

4K and 8K video application solutions led by 5G and AI technologies will reconstruct the intelligent security system for security scenarios. Smart security mainly uses basic equipment such as video applications and sensors to transmit key information to intelligent systems, realize more dynamic real-time video analysis applications, and further achieve the purpose of predicting threats and responding in a timely manner. 5G+AI technology will improve the application system's functions such as high-speed transmission of massive data, high resolution, and intelligent decision-making, making the entire journey visual and promoting the development of ultra-high-definition video applications.

5G + AI + video is "smarter and clearer"

In the field of video surveillance, "ultra-high-definition and smarter" video surveillance is one of the main development directions of the security industry. The previous 8M IP camera network transmission speed is not fast enough, the response is slow, the post-verification and the low efficiency caused by manual decision-making are unable to meet the needs of data collection, especially the small movements of the human body, subtle features, fragmented external parts, small cracks on the equipment, small black spots and other details in the picture have exceeded the recognition ability of the existing monitoring.

4K and 8K security monitoring solutions and related application scenarios with high frame rate, ultra-high definition and wide dynamic range led by 5G+AI technology will become an inevitable choice. AI intelligent algorithms will parse more detailed information including the appearance, characteristics, movements, behaviors, etc. of the human body from the video. For example, in terms of power monitoring and maintenance, users can directly observe the operation of power transmission lines and power equipment through ultra-high-definition video images, greatly reducing time and labor costs; in the field of industrial manufacturing, higher-definition display technology can replace the current industrial defect monitoring technology on the production line.

5G + AI + video applications are more convenient and faster

During various major events, the network cabling, power cables, wireless quick-control ball kits, etc. that can be seen everywhere on the ground are important security conditions for an event. How to meet the needs of on-site monitoring for network and power supply without damaging the environment and road surface and ensuring safety has always been a difficult problem for security units and construction units.

"Video + 5G + AI" is a new combination to solve this problem. 5G can quickly and securely transmit surveillance videos to the command center, and based on the edge computing capabilities of AI, AI cameras can provide all the computing power support on the device side, thus forming a new rapid deployment and monitoring solution.

"5G+AI camera+mobile battery pack" can not only play an important role as a rapid deployment and control equipment in the security of major events, but also play a huge role in some scenarios that require temporary deployment and control, such as roadside security, checkpoints, temporary checkpoints, rivers, and places with high construction difficulty.

Driven by the dual technologies of "5G+AI", AI algorithms such as face recognition, behavior recognition, license plate recognition, and target classification will be more widely used in the future due to ultra-high-definition video surveillance, and the boundaries of security applications will be further expanded.

5G+AI ultra-high-definition intelligent video surveillance will be widely used

Busy public places: real-time accurate regional flow of people

High-point 5G+AI ultra-high-definition monitoring has unique application advantages in large scenes and complex environments. The efficient video transmission rate and edge real-time intelligent analysis capabilities enable it to play an important role in busy public places with large traffic flow.

The AI ​​algorithm based on head and shoulder detection can assist high-point monitoring to accurately count the real-time flow of people in the entire area in high-definition images, form more accurate crowd statistical analysis reports and predictions such as congestion analysis, and solve problems such as repeated crowd analysis and low accuracy of trend analysis due to the limited single-screen scenes of ordinary monitoring.

The AI ​​algorithm based on deep learning can accurately identify the physical features and behavioral movements of people from high-definition images, and make intelligent responses and processing in the background in a timely manner. For example, it can accurately identify the difference between waving and asking for help, the difference between running and brisk walking, and distinguish the differences in physical appearance and behavior of different people.

The ambient light in busy public places with large flow of people places higher demands on the performance of the monitoring system. Video surveillance with wide viewing angles and high positions requires higher-definition pixels to ensure the accuracy of recognition. These application requirements also place higher demands on data traffic. The high-speed transmission advantage of 5G can better meet the implementation of such scenario applications.

Critical security infrastructure: Intelligent analysis of abnormal conditions

The high transmission rate of 5G provides good network conditions for ultra-high-definition video images. For critical infrastructure, ultra-high-definition video surveillance can improve the security level around the facilities and can also quickly make intelligent analysis of abnormal conditions.

Based on the in-depth research of AI algorithms, intelligent analysis can be performed on the physical appearance and behavioral characteristics of people in the warning area of ​​key infrastructure. In addition to face recognition analysis, it also includes the recognition and collection of information such as human body characteristics and appearance characteristics; the abnormal status of key infrastructure can also be detected in real time in high-definition images, including abnormalities of doors, equipment, lines, etc., and automatic analysis and warning can be made. In this way, video surveillance can be used to collect security linkage applications from multiple aspects such as faces, bodies, and basic key facilities.

Ultra-high-definition smart community: monitoring of facilities and personnel, and emergency response

On March 2, 2019, the Ministry of Industry and Information Technology issued the "Ultra-High Definition Video Industry Development Action Plan (2019-2020)", which pointed out the future development direction of the domestic ultra-high definition video industry. The action plan requires that by 2020, 4K cameras, monitors, switchers and other special equipment for gathering, editing and broadcasting will form industrial capabilities, and carry out application demonstrations based on ultra-high definition video in the fields of culture, education and entertainment, security monitoring, medical health, etc., and the community is the first stop for the ultra-high definition video industry to land.

Community ultra-high-definition surveillance creates a smart community with ultra-high pixel and wide-angle image quality. It can identify abnormal targets in roads, parking spaces, substations, garbage rooms and other areas within the community, such as residents falling, calling for help, children and the elderly walking alone, and abnormal running movements. It can not only achieve overall target recognition, but also take into account key details, such as individual faces and small movements. It can provide more details for AI and improve its efficiency and accuracy.

In community applications, from outdoor license plate recognition, commercial, facial access control, visitor, elevator control to indoor smart access control, smoke alarm, smart switch, etc., AI and 5G are indispensable. The data collected by a large number of IoT devices needs to be aggregated into the intelligent platform through 5G, and then the instructions for recommendation, prediction, and judgment are accurately sent to the devices, turning the traditional device linkage mode into a more intelligent joint linkage mode, making smart devices smarter.

In addition to ultra-high-definition radio and television, cultural and educational entertainment to enrich residents' cultural and entertainment life, AI smart communities also improve residents' living safety experience and quality. 5G is the bridge connecting AI and IoT, and is an excellent combination of the latest self-developed technology and community scenario applications.
