Due to the particularity of the prison itself, the prison security system covers a wide range of areas, including: integrated wiring, video surveillance, perimeter alarms, high voltage power grids, access control, emergency alarms, patrols, intercom, public broadcasting, interview recording, supervision More than a dozen subsystems such as information. Among them, the requirements for safety and reliability of security systems are significantly higher than other industries.
In recent years, although the prison security system has made certain progress in terms of intelligence, due to various reasons, there are still problems that need to be improved. For example, the security system of the judicial system now has problems with the compatibility of old and new systems and the transformation of old systems. Due to the batch construction, the lack of uniform standards, and the large number of security manufacturers, there is no unified standard agreement, resulting in more than one system in most units, each subsystem is running independently, information can not be shared, and there is no correlation between them. Formed an information island. In the event of an emergency, the systems cannot be associated with each other in time, and video surveillance images and other security resources cannot be shared, resulting in the management not being able to respond intuitively. It is impossible to quickly and efficiently play the role of early warning and prevention; it is difficult to check and find afterwards. Recording the correlation between information, wasting manpower and material resources, resulting in low management efficiency.
In addition, the requirements of the Ministry of Justice for digital security management systems are not only as simple as security monitoring, but also require a new level of information construction, in order to achieve digitalization of information resources, network of information transmission, popularization of information technology, and information management. Intelligent goal. The compatibility of new and old systems seems to be important in the entire security system, and the economic value of the new system cannot be ignored. The implementation of the compatibility of the old and new systems not only requires high requirements for the new system, but also cannot discard the traditional management applications of the old system. Only by optimizing the comprehensive application compatible with the old and new systems can the efficiency of the prison security integration platform be better realized.
Based on years of experience, traditional simulation solutions have many drawbacks. After one year of system operation, many BNC heads and lines are seriously aged and maintenance work is huge. The scalability of the system is poor. In some places, after the system is designed for a period of time, it is necessary to increase or decrease the points in some monitoring areas, and the budget for the supplementary points is difficult to be in place. This is a common problem in the operation of the simulation system.
The pure million HD webcam solution also has a single device type in actual use, and many front-end explosion-proof or some special functions cannot be effectively integrated. There are also some problems with pure network cabling to each point. Relatively speaking, the cost of the whole system is larger than that of the simulation.
We now mainly promote the VK-9900 series coding platform. The front end adopts flexible and diverse analog equipment, which is centrally coded in a small range, converted into a network digital signal, and then transmitted to the monitoring center via the optical transceiver. This not only has the flexibility of the analog system, but also the advantages of the digital system expansion and maintenance. The central backbone network forms the network structure, and the end can be collected through the coaxial line. At the same time, it can integrate some million HD network cameras and intelligent devices in the key areas, and the back-end unified digital matrix and DID splicing screens form a whole-generation solution for large-scale network LCD TV video wall.
Shenzhen Huaantai Company has started research and development breakthrough in coding technology since 2008. At present, it has formed a mature and feasible solution. The front end uses analog monitoring equipment, and the back end uses encoder to encode digital signal transmission and decode the upper wall to solve the prison. The system is old and new compatible with the upgrade problem and the upgrade of the analog system to the digital system.
Taking a prison project in Jiangxi Province as an example, there are 23 main buildings in a new prison area in Jiangxi Province; there are 7 buildings in the building, 3 labor houses, 1 logistics building, 1 hospital, 1 teaching building, criminals. 1 building, 1 high-security monitoring area, 1 meeting building, 1 old disabled building, 1 north gate, 1 prison office building, 1 police training room, 1 standby building, 1 dry police canteen The wall is about 1,500 meters and the guard building is 10.
The construction and development of the informationization of the prison is based on the standards of the modern and civilized prison of the Ministry of Justice and the requirements of the National Prison Informationization Construction Plan. Based on the efficient and safe network facilities, the premise of the scientific and standardized standard system is the function. Focus on complete application systems, adhere to scientific planning, overall planning, step-by-step implementation, and classified management, accelerate the construction of prison informatization, improve the technical support capability of prison penal enforcement, improve the application level of information technology in prison work, and improve the vast number of applications. The overall quality of the prison police, maintain the security and stability of the prison, improve the quality of criminal rehabilitation, promote the reform and development of prison work, and better play the role of the prison in serving the building of a harmonious socialist society.
This project has been designed since 2008. After more than two years, the network layout has exceeded 2,000 points, and it is a medium-sized and large-scale project in the national prison security system. When the prison's new surveillance area was rebuilt, VIKOR monitoring equipment was used from the front-end camera to the back-end storage equipment. The front end mainly used VK-D280-PT low-light dome camera and VK-K601X-PT low-illumination gun camera. With the strong support of the prison leadership and management, the joint efforts of the factory and the prison have made the prison's monitoring system very successful. At present, the technical equipment of the prison has reached the domestic leading level, and the legal, scientific and social level of the prison is also in the forefront of the country. The first phase of the project has been completed, the system is stable and the image is clear.
The central computer network system of the prison should establish a backbone network with advanced technology and extensibility, covering all functional areas of the prison, connecting various PCs, workstations, terminal equipment and local area networks of the prison to form a reasonable structure. Computer network system, and on this basis, establish a software and hardware environment that can meet the daily work and management of the prison, develop various information bases and application systems, and provide sufficient network information services for the prison staff.
In response to these requirements, the guiding ideology of the overall design plan is: functional application, advanced technology, economical rationality, convenient maintenance, sufficient room for expansion and compliance with the requirements of sustainable development of system technology, reflecting intelligence and meeting informationization. Development requirements.
After many field visits and equipment testing, a complete system solution has been formed, which has the following important features:
First, practicality and economy: always implement the application-oriented, pragmatic approach, adhere to the principles of practicality and economy, and maximize the potential of existing equipment. The most effective use of the equipment in the old system, the new system uses a professional prison camera, from the lens to the most professional configuration of the built-in configuration.
Second, compatibility and scalability: compatible with existing equipment, based on existing equipment for resource integration and potential digging; can seamlessly expand to support future new equipment, new features. Modular combination system, the front end uses analog monitoring equipment (anti-riot dome camera, wide dynamic gun camera), and the back end uses digital information system equipment.
Third, advanced and mature: the use of advanced integration concepts, technologies and methods to achieve management innovation, while paying attention to the relative maturity of system technology and equipment. The design is carried out synchronously with the infrastructure. In the infrastructure construction, all the weak electric wires are buried in advance. This alone saves a lot of wiring costs and improves the system's effectiveness.
Fourth, reliability and stability: fully consider the system structure, equipment performance, management process, maintenance capabilities and other factors to ensure the reliability and stability of the system operation. Using advanced million HD network cameras, the images are stored in a centralized manner to ensure the stability of the stored data.
V. Openness and Standardity: Establish a security information integration platform, which can seamlessly integrate OA and prison administration systems; reserve the interface with the provincial bureaus. This project is the largest in the existing prison security system. The construction of the province's integrated prison information integration platform plays a standard demonstration role.
The integrated security management plan of the prison uses the integrated management system as the platform and the network video technology as the core to realize the interconnection and intercommunication of various security resources of the prison. Through the effective transformation of the old system and the rational use of the old and new systems, the prison is effectively improved. Intuitive and convenient management and prevention.
Prisons are an important place for national security. Prisons are also making progress in the use of new technologies and the introduction of new design concepts. From the current point of view, it is imperative to strengthen the transformation of new and old systems. Secondly, the units with conditions should transition from passive monitoring to active monitoring. Through intelligent video analysis, active warnings can reduce the monitoring workload of the police. Computer, communication, multimedia and control technologies are developing rapidly. Under the general trend of digital integration, networking and intelligence, VIKOR is one of the earliest manufacturers in Shenzhen to focus on the development and production of millions of high-definition network cameras. The industry has a unique advantage. It is the recommended brand enterprise of the Ministry of Justice, providing professional products and quality services, and contributing to the construction of the prison security integrated system.

Prison is a special area of ​​high risk and seriousness. It is internally held by people who violate the national criminal law or criminal procedure law. Once a prison escape occurs, it is easy to cause extremely serious damage and influence on social security and stability. Potential social threats cannot be ignored. Therefore, prisons have always been an important and mature place for the application of security systems in China.
