Application of Intelligent Video Analysis in Digital Prison

The prison is a place where prisoners are confined and reformed, and is one of the important state machines. The safety precautions of prisons, that is, whether or not criminals escaped, homicides, abnormal deaths, and other accidents affecting the safety and stability of prisons have brought about extremely unfavorable negative effects on social stability and the country’s tranquillity. Especially in the context of “building a harmonious society”, it is particularly important to construct a prison security system. Therefore, in the public security and judicial departments, the “policing of science and technology to police force” has become a trend in the management of prisons.

In recent years, despite the constraints of various restrictions such as the size of the incarceration, hardware facilities, and the execution system of penalties, the high degree of attention to prison security, the large number of prison safety talks, and the large investment in prison security may be unprecedented. Wu Aiying, Party Secretary and Minister of the Ministry of Justice, emphasized in the national prison director’s seminar at the National Prison Political Commissar Training Course that he must conscientiously implement the Party Central Committee and the State Council’s spirit of decision-making, deployment, and important instructions regarding prison work, and closely focus on further promoting social contradictions and social dissolution. Three key areas of management innovation, fair and honest enforcement, further strengthen the formal management of prisons, improve the quality of education reforms, ensure the continuous security and stability of prisons, and make new contributions to maintaining social harmony and stability and promoting stable and rapid economic development.

Prison work has always been valued by the Party Central Committee and the State Council. In particular, in recent years, the national prison system has persisted in focusing on the center, serving the overall situation, conscientiously fulfilling its functions, and continuously forging ahead. It has made remarkable achievements in all its work, and has made positive contributions to maintaining social harmony and stability and promoting economic and social development. The new situation and new tasks have put forward new and higher requirements for prison work. It is necessary to effectively strengthen emergency prevention and emergency management. Prison work must always regard strengthening the prevention of prison emergencies and emergency management as an important task, and vigorously improve the ability to prevent and respond to emergencies.

It is necessary to reinforce the ideological defense line, strengthen air defense deployment, improve physical defense facilities, improve technological defense capabilities, improve the joint defense system, and establish “a solid line of defense, tight deployment of personnel defense, perfect physical defense facilities, advanced technological defense means, coordinated defense coordination, and emergency disposal. "Efficient" integrated management, prevention, and control of the emergency management system for all types of emergencies to predict, predict, prevent, early warning and effective disposal.

Video surveillance is the basis of the entire prison security system. It not only ensures that all activities of detainees are within the line of sight of the on-duty police officers, but also ensures that video files are available for verification after the accident. Therefore, the prison video surveillance system is an important tool to improve the level of prison security and technical protection. It plays an irreplaceable role in supervising the reform of prisoners and preventing emergencies in prisons.

Prison Video Surveillance System Status The prison is an important part of the state's violent security agency, and is responsible for the education and reform of criminal personnel. Because in view of its own functional requirements, prisons require significantly higher safety and reliability requirements for security systems than other industries. The prison security system involves a wide range of areas, including network communication technology, information technology, electronic sensing intrusion detection, video imaging monitoring, access guard patrol, multimedia conferences, emergency command, emergency plans, social engineering, and more than 10 subsystems. However, the operation between the system and the system is relatively independent, information can not be shared, there is no correlation between each other, forming an island of information. In the event of an emergency, systems cannot be linked and linked in a timely manner. Monitoring images and other security resources cannot be shared, causing the management to fail to respond intuitively and quickly and efficiently play the role of early warning and prevention. Afterwards, it is difficult to uniformly check and search for records. The correlation between them is a waste of manpower and material resources, resulting in low management efficiency. The requirements for digital security management systems in prisons are now not only simple for security monitoring, but also related to the supervision of police officers and the daily supervision of prisoners. The systematic information islands have not been able to effectively protect the rights and obligations of prison guards and detainees, leading to unnecessary disputes.

At present, the closed-circuit monitoring system widely used in domestic prisons adopts matrix host control, monitors the front-end monitoring screen through the TV wall, and uses long-delay analog video recorders for recording and playback. This type of traditional video surveillance mode can only be used for ex post facto forensics in most cases and cannot play a role in prevention and warning. Since the monitoring system itself is controlled by humans, there are certain limitations in the monitoring capabilities. These limiting factors make the video surveillance system more or less alarm accuracy, false positives and false negatives, long alarm response time, Defects in video data analysis, such as difficulties, lead to a reduction in the overall system security and practicality. Strictly speaking, these are insufficient to meet the requirements of such a high security level of the prison system.

The emergence of intelligent video surveillance technology is to solve some of the defects inherent in traditional video surveillance systems. With the advent of intelligent video surveillance technology, the transition from passive to active surveillance has been realized. It is able to perform video surveillance continuously around the clock and automatically detect abnormal situations in the surveillance screen, thus helping staff to more effectively deal with crisis, and Minimize the phenomenon of false positives and false negatives to meet the security requirements of prison security systems.

The NPE Prison Intelligent Security Solution is based on digitization, network orientation, intelligent video analysis technology as the core, and a multi-level management program as a platform to integrate the separate and separate systems of the prison to form a one-piece solution. Realize the integration and integration of other security resources such as perimeter alarm, high-voltage power grid, emergency alarm, patrol, access control, intercom, public broadcasting, interview recording, supervision information, etc., to achieve management convenience, data intuitiveness, system intelligence security Other purposes.

The rapid response can also provide verification information within a certain period of time before and after the event, greatly reducing the pressure on supervisors and improving the efficiency and quality of management.
