Preface
Prisons are national first-level risk units. The security of prisons is related to the stability of the society. Traditional security methods have gradually been unable to meet the security needs of the new era. The concept of multi-system integration and unified management has been reached in the prison and security industry. consensus.
Project Introduction
Under the wave of prison information construction and comprehensive improvement of prison security control, a prison has adopted advanced security technology to comprehensively improve prison security and management. In addition to the construction of traditional alarm, patrol, access control, voice intercom, fence, AB gate, high-voltage power grid and other technical defense and physical defense facilities, it also focused on three aspects: first, flexible construction and deployment, and system stability , A video surveillance system that can be centrally managed; the second is to achieve full integration and comprehensive management of the decentralized security systems to improve management efficiency; the third is to achieve real-time linkage between the video surveillance system and other security systems to enhance the prison’s comprehensive security capabilities.
In response to the security needs of a prison, Keda provides a complete set of solutions. One is to build a fully functional and centralized management video surveillance system based on a networked architecture; the other is to provide a comprehensive security management system for each security subsystem Carry out a high degree of integration and unified management, and realize the linkage between the video monitoring subsystem and other security subsystems, and finally comprehensively improve the prison’s comprehensive security capabilities and management efficiency.
1. The construction of network video surveillance system
Networking can ensure the openness, compatibility and manageability of the video surveillance system, while making system deployment more flexible and convenient. It is also a necessary condition for the integration and linkage of video surveillance images with other security systems.
A prison video surveillance system is based on a networked architecture, adopts the deployment plan of “one-level platform, two-level center”, and uses the Kodak monitoring management platform as the core to realize the flexible deployment and centralized management of the entire system. More than 300 video surveillance point images are gathered to the master control center through the analog monitoring system, and are divided into two channels by the video distributor. One channel is directly connected to the TV wall through matrix control to ensure the real-time and high-definition image, and the other channel is centralized through Kodak KDM201 After encoding, the encoder is connected to the Keda monitoring and management platform, which is forwarded, stored and managed by the management platform.
“First-level platform” refers to the unified network management of all equipment in the system based on a single platform, with a high degree of system integration and flexible authority management; “two-level center” refers to the general control center and the sub-control center, which is the management mode usually adopted by prisons. .
Master Control Center
The general control center is deployed in the prison administration building. It is the command and control center for the entire prison security business. It has the highest management and scheduling authority, and plays the role of monitoring, command, scheduling, coordination and control of the entire prison security. The central control center deployment, central management platform, IP SAN storage, TV wall decoding and control clients and other facilities, all surveillance point videos are collectively encoded and uploaded to the central control center monitoring and management platform through the local area network, and the management platform is unified Distribute, and realize centralized video storage and decoding on the wall.
A certain prison has very high requirements on the security, reliability and image quality of video storage, requiring 24 hours of uninterrupted video recording. The video storage time is generally 15-30 days. The image quality adopts a mixed method of D1 and CIF. Key areas such as prisons , Workshops, surrounding walls, etc. use D1 image storage, and other secondary areas use CIF storage. This system uses IP SAN disk arrays for centralized storage in the master control center. IP SAN arrays have significant advantages such as high reliability, large capacity, and scalability, which can ensure highly reliable storage of videos, while preventing illegal deletion and facilitating centralized management.
Sub-control center
A prison is divided into multiple prison areas by building, and each prison area has a sub-control center. After the general control center is authorized, each sub-control center can control and manage the monitoring points in its jurisdiction. Users can view the monitoring points in the monitoring area by logging in to the central management platform through the sub-control client PC. Adopting the “one machine with dual display” browsing mode, one screen displays the monitoring screen and the other screen displays the electronic map. The two correspond to each other, and the location and specific conditions of the alarm points can be determined more intuitively and quickly. The establishment of the sub-control center realized hierarchical and domain-based management, shared the monitoring pressure of the general control center, refined the monitoring work, and improved the emergency response speed.
Based on the management principle of classification and decentralization, the monitoring platform can assign different permissions to users at all levels. The master control center can manage and call all monitoring resources. Each sub-control center can only manage and call the monitoring resources under its jurisdiction. For special needs, users at all levels can’t skip access.
Unified management of the prison administration
Based on the network characteristics of a prison video surveillance system, the prison administration can realize remote viewing and decoding of surveillance images on the wall by setting up a sub-control center. With the help of the multi-level cascading feature of the Keda monitoring and management platform, the prison administration can also cascade through the deployment management platform and the management platform of the prison under its jurisdiction to form a larger-scale distributed networked monitoring system to achieve more effective, More convenient unified management and centralized scheduling.
The security construction of a prison this time will fully reflect the advantages of integrated management. Keda’s integrated security management solution for prisons can realize video surveillance, access control, patrol, intercom, public broadcasting, AB gate, high-voltage power grid, etc. through a unified platform The unified management of various security subsystems simplifies the management process, improves management efficiency, and can realize the integration and linkage of video surveillance and other security services, and enhance the comprehensive security capabilities of the prison.
The entire system is composed of an integrated management platform, an integrated management client and multiple security subsystems. The integrated management platform is the core of the system. It is deployed in the main control center and is responsible for the access and unified management of all security subsystems, as well as the realization of video surveillance and Integration and linkage of other security businesses. The integrated management client provides users with a unified login, operation and management interface.
2. Comprehensive management of each security subsystem
Alarm management
Through the integrated management platform, unified management of various manual and automatic alarms such as emergency alarm buttons, perimeters, and high-voltage power grids can be realized, including the setting of alarm points, operation and group management, alarm plan settings and alarm information query, etc.
Intercom management
Through the integrated management platform, the intercom equipment in prison warehouses, corridors, duty rooms, watchtowers, family meeting rooms and other areas can be managed uniformly, including group management of intercom points, control operations, status display, linkage settings, etc.
Patrol management
Through the integrated management platform, each patrol point can be managed uniformly. Including patrol point group management, patrol plan setting, patrol status display, linkage setting, etc. After the patrol record is uploaded in real time through the patrol system, the patrol record can be inquired.
Access control
Through the integrated management platform, the prison access control system can be uniformly managed. Including access control, group management, alarm settings (such as the door has not been closed within the specified time / multiple wrong passwords / input duress password / malicious access control), access control status display, card swiping record query, linkage settings, etc.
Video surveillance management
Through the integrated management platform, the video surveillance system can be managed uniformly. In this system, all management and business functions in the video surveillance subsystem can be realized, such as image browsing, video storage, retrieval and playback, equipment grouping control and management, user and authority management, network management, log management, and alarm linkage, etc. .
Third, the integration and linkage of video surveillance and other security systems
In addition to the unified management of various security subsystems, the prison security integrated management system can also realize the linkage between video surveillance and other security subsystems, embodying the intuitive and convenient advantages of video information in all other security services. A prison security integrated management system can realize the following video linkage services:
Alarm linkage
Once an alarm occurs in the prison, the video surveillance subsystem will automatically issue a sound and light alarm, switch the image of the alarm point to the wall, capture the image, and start video storage. At the same time, a pre-edited alarm processing plan will pop up to remind the prison guards of the next processing process. In addition, the LED information screen of the monitoring center separately displays the warning text information, and the large screen displays the warning image and electronic map. The video corresponds to the warning information and the warning point one by one, which is intuitive and clear, so that the prison guard can understand the warning situation in the fastest time.
Access control linkage
Based on the integrated management service platform, the video surveillance subsystem can be linked with the access control subsystem. As long as someone swipes the card, it will automatically capture the scene image and start the video storage to record the personnel entry and exit information in time, leaving a real-time entry and exit record for each entry Image and video information. At the same time, the card reader can be compared with the legal personnel information in the prison administration information system in real time. For illegal intrusion events, such as the door has not been closed for a long time, the wrong password has been entered many times, and the access control system has been maliciously damaged, the access control system will send out an alarm message to trigger a series of linkage operations of the monitoring system.
Patrol linkage
The integrated management system can realize the linkage between the video surveillance subsystem and the electronic patrol subsystem. The police officer on duty will automatically trigger the video surveillance system for image capture and video storage when the patrol point button is registered. If there is no patrol record within the specified time, the linkage operation of the monitoring system will be triggered through the alarm information of the patrol system, and the video image in the corridor of the alarm floor will be automatically displayed on the large screen of the monitoring center, and the electronic map will be synchronized with the alarm prompt.
Intercom linkage
Through the integrated management system, the video monitoring subsystem can be linked with the intercom subsystem. Once the phone is taken, the monitoring subsystem is automatically triggered to make a series of linkage operations, including switching the monitoring warehouse image on the wall, starting video storage, etc., for recording The live video information of the prison room during the intercom. All intercom records can be queried in the system, and the corresponding video files can be viewed.
AB door linkage
Door AB is used to identify the personnel entering and exiting the prison, and to provide security for the inspection and testing of entering and exiting vehicles. Through the linkage of the video surveillance subsystem and door AB, when a person or vehicle enters door A or door B, the video surveillance system is automatically triggered to capture images, switch images to the wall, and record video at the same time. If an abnormal situation occurs, an alarm is automatically triggered, and the corresponding linkage operation is performed to lock the target in the buffer between AB.
High-voltage grid linkage
Through the integrated management system, the video monitoring subsystem can be linked to the high-voltage power grid. When a power grid alarm occurs, the monitoring center automatically pops up the alarm point image, starts the video storage, and the linkage broadcast system provides the highest-level voice warning prompt, and the searchlight executes the alarm area. The comprehensive management client pops up the “Prisoner Escape Treatment Plan”, and the on-duty prison guards follow the procedures marked by the plan for emergency treatment.
digital map
Electronic map is an important component and tool in the integrated management system. A prison integrated management system integrates a multi-layer electronic map. Subsystems such as alarm, access control, intercom, monitoring, and corresponding equipment all realize intuitive information point positioning, query and management on the map. The electronic map is managed by the layer tree. The prison areas, floors, security points, security subsystems, and security equipment are presented in a list. The user only needs to click on the corresponding sub-category, and the electronic map will jump to the corresponding interface, and different maps You can jump directly between layers, without jumping step by step, and browsing is simple and convenient. When an alarm occurs, the electronic map will automatically locate the alarm point and flash a reminder. The user can click on the alarm point to switch to the real-time video of the alarm point to view the specific situation. At the same time, the electronic map also provides a thumbnail function, so that the user can still grasp the overall situation when viewing the interface of a certain alarm point.
Fourth, the conclusion
Digitization, networking, and integration are irreversible trends in the security field, and “comprehensive security management” is the only way for prisons to strengthen security construction. The prison security integrated management solution adopts advanced digital and network technology to integrate multiple prison security subsystems to truly realize the prison security and create a safe defense system for a prison.
