See how Hikvision uses artificial intelligence to secure campus security
Campus security is greater than days.
On campus, we listen to the sounds of books, smell the paper and ink, and the school education has a long history and is associated with thousands of families. The safety of the campus is directly related to the peace and stability of the entire society. However, in recent years, the incidents of vicious criminal cases, child abuse cases, and sexual assaults on campus have frequently appeared in newspaper networks. Campus security issues have become increasingly prominent, and campus security has gradually become the focus of social attention.
Under this circumstance, the General Office of the State Council has also promulgated the "Opinions on Strengthening the Construction of Safety Risk Prevention and Control System for Primary and Secondary School Kindergartens". The opinion pointed out that the education supervision institutions at all levels of the People's Government should regard school safety work as an important part of education supervision. Further improve the school's measures of civil air defense, physical defense, technical defense, etc., and promote local areas to do a good job in risk prevention, control, accident handling and risk mitigation as soon as possible.
As the world's security giant, Hikvision has quickly launched a comprehensive campus security solution in the face of the increasingly prominent campus security issues and the urgent need for school management.
What is the key to campus security management?
According to Su Hang, senior management manager of Hikvision, campus security is divided into higher education security and general education security. The business scope of the two is different. For the general education, the security system of the education system has a single source of funds and a small scale. Therefore, the brand awareness and popularity requirements are lower. Therefore, this market competition is fierce. In addition to the need to improve the cost performance of its own products, various security companies need to improve the service value of their products. For higher education, the project is larger and the sources of funds are richer. More recognition of market brand products, more concerned with mature engineering cases and product features and added value of services. Therefore, security manufacturers should launch their own special products and industry solutions for the higher education market, providing customers with one-stop services, products to create markets, services to create value.
The main target of Hikvision is the higher education market. The high education security is mainly composed of civil air defense, technical defense and physical defense. The three are indispensable.
In recent years, with the continuous development of science and technology and the ever-changing needs of users, it is necessary to make the increasingly large and increasingly complex campus security business continue to play its due capacity, improve the response speed and disposal capacity of civil air defense, and deepen the technology. The system business and humanized design of the defense, the use of the physical defense and the life of the system are urgent problems to be solved in campus security.
In his view, the scope of campus security management is relatively wide, and it can be summarized as the management of people, cars and things. The current campus security infrastructure (video surveillance) is relatively complete, providing post-mortem verification and simple incident alert services. However, with the strengthening of social security, the expansion of school education, and the public's attention to campus safety, campus security management needs to be developed in a refined way, through pre-existing prevention, safety supervision and events through more advanced technical means. Track disposal. The key to refined management is to accurately identify and classify different management objectives, and to extract target information (such as deep learning technology, Internet of Things technology, big data analysis technology, etc.) by using multiple technologies.
He said that the campus security system is divided into three parts: data collection, data storage, and data application. Today's products and systems have changed dramatically compared to earlier systems. The previous analog video surveillance images were invisible, incomplete, and brand confusing; the monitoring networks of each branch were independent, and the actual video resource utilization rate was low, which restricted the expansion of the construction system.
Nowadays, in the data acquisition process, the 2 megapixel camera becomes standard and develops towards higher definition (4K, 8K); the night vision effect achieves a qualitative leap, and the camera with the latest technology still has the brightness of 0.0004Lux environment. Can complete clear color imaging; through the "edge calculation" technology, the camera itself can support multi-dimensional information extraction and recognition of face, human body, license plate, vehicle attributes, etc., greatly improving system availability; in camera classification, new A variety of specialized products such as thermal imaging, wireless transmission, and Internet of Things.
In the data storage segment, cloud storage has become a new favorite. Different cloud storage products can be selected for different data (video data, structured data, etc.), and the corresponding cloud storage systems are supported for different construction scales, making the system more flexible, data safer, and writing. More efficient.
In the data application process, cloud computing has proved its enormous practical significance in many industries and projects. Through cloud computing, users can find more events that cannot be judged in the vast amount of data, greatly reducing the manpower input of security management, and providing a scientific basis for accurate management.
Hikvision uses "AI" to protect the safety of Huanong campus
Referring to this, Suhang also gave a detailed case to Lei Feng.com (Public No.: Lei Feng). Hikvision deployed a complete comprehensive security system for colleges and universities in Huazhong Agricultural University, including over 7,000 acres of campus monitoring, key personnel control, vehicle management and control of entrances and exits, and police and student-intensive areas. The monitoring center comprehensive command and other services help users complete smart security upgrades, realize the transformation of preventive measures beforehand, and provide users with more precise and efficient management services.
Among them, Haikang also applied a lot of AI products.
Front-end equipment such as “Haikang Squat†and “Hikang God Capture†completes the structural information extraction and feature modeling of people and vehicles:
Due to the regularization of the life and study of teachers and students in colleges and universities, it is easy to appear the peak period of human traffic, which leads to the recognition of a person's face in a short period of time. This has put forward higher requirements for the face grabber. Traditional face collection is often limited by angles, capture rates, etc., and cannot effectively solve the above problems. In this regard, Hikvision launched the “Haikang Squat†face acquisition camera based on technologies such as deep learning, which has greatly improved the selection of capture angles and imaging images. It is worth mentioning that its parallel processing capability is also improved. At the same time, it is possible to detect and capture 30 faces at the same time, which effectively ensures the face capture effect.
Back-end equipment such as “Haikang Facebookâ€, “Hikang Super Brain†and “Hai Kang Falcon†complete the comparison and alarm of structured information and target features:
The flow of people in colleges and universities is huge. According to the scale of 20,000 teachers and students and the frequency of 10 times per person per day, there are 6 million face pictures per month, more than 70 million pieces per year, and more than 200 million pieces in 3 years. It makes it difficult to store and extract massive data. In response to this, Hikvision also provides a "Hikang Facebook" series of servers that support cluster GPUs different from the previous X86 architecture for data secondary structuring, enabling face multi-condition retrieval, face search and other requirements; In addition, for the dormitory, key laboratory and other scenes, "Hikang Super Brain" can quickly analyze the face image, complete the face comparison in a short time, realize face recognition, blacklist control alarm, no permission stranger Enter the alarm and other services.
Difficulties in the program and the focus of Party A (school)
Of course, before and after the project deployment, there are some difficulties. Su Hang said that in the process of practical application of deep learning technology, how to design intelligent analysis services corresponding to different scenarios and the feasibility and replication of such services Sex is a problem that needs to be solved. In response to this, Hikvision is also better able to solve the above problems by communicating with the first-line users, business needs, research and development, continuous improvement of the effectiveness of intelligent analysis, in-depth project verification and correct application mode.
In the view of Suhang, it is not easy to bid on a project. In the process of communication with Lei Feng.com, he also shared several aspects that Party A is concerned about when adopting relevant programs:
Whether it meets its current management needs and meets the expected construction content;
Whether it has flexible capacity expansion and upgrade capabilities to ensure future business applications;
Whether it has certain advanced nature, improve security capabilities, and reduce manpower input;
Whether it has an easy-to-use maintenance function to ensure reliable operation of the system.
He said that the campus security business tests the company's research and development capabilities and project delivery capabilities, and also challenges Party B's project design experience. If the company wants to get involved, it must understand the user's pain points and be able to propose different business needs for different customers. System design and future construction planning, using mature and deliverable science technologies (such as deep learning, big data, cloud computing, etc.) to help users deepen their refined management capabilities, improve system value and reduce construction costs.
Conclusion
The campus can be said to be the purest and hopeful place. Every campus security incident happens to touch everyone's sensitive nerves. Fortunately, with the development of related technologies, technical defense has largely solved many problems in campus security work. In the future, campus security construction must continue to be subject to requirements, technically continuous improvement, and continue to maintain in the field of civil air defense. The combination of the two maintains the pure land of the campus, making the campus more secure and more savory. mine
