Overview of intelligent monitoring solutions

[ Huaqiang Security Network News ]

China Security Network Xiaobian talks about intelligent monitoring solutions. With the development of video surveillance systems in the judicial prison management system, the existing passive manual monitoring is no longer able to meet the regulatory needs of the new situation, especially Now relying on the video surveillance method of polling, it is impossible to defend and deal with the first time of sudden malicious events. To complete the heavy real-time monitoring tasks of the prison, ensure the safety of the supervision office, and give full play to the role of the video surveillance system, it must develop towards active intelligent monitoring.

The intelligent video behavior analysis and alarm system provides a new means of technical realization for the modern prison management system. Its successful use will greatly improve the timely defense against vicious incidents, filter invalid information, and liberate police force; Discover and dispose of more and more kinds of emergencies that are currently occurring in domestic prisons, greatly reduce the occurrence of similar accidents, and implement the â€œscientific and technical policeâ€ strategy to meet the â€œmodernization office service system reform and information guidanceâ€. The need for service. The ultimate goal is to establish a monitoring system based on intelligent video surveillance technology, and combine intelligent video analysis system with prison management system and information system to provide a new video intelligent behavior analysis solution for public security supervision and judicial prison system.

Overview of intelligent monitoring solutions

Intelligent monitoring solution overview

First, the new security needs of prisons

The system construction content is mainly divided into the scenes within the institution, the external scenes, and the key parts of the supervision office.

Scenes within the institution: Through the daily security surveillance video of important parts such as the indoors, the confinement room, the review room, the wind-dissipating place, and the labor place, the detainees are overtaken by certain warning lines, abnormal climbing, nights, abnormal movements, abnormalities. Automatic analysis, prompting, early warning and alarm functions are realized by aggregating, entering a specific area and not returning for a long time.

External scene area: Through daily security surveillance video set up in prison walls, perimeters, specific isolation areas, etc., automatic analysis, prompting, early warning and alarm for all kinds of abnormal behaviors such as crossing walls, perimeters, and entering specific isolation areas . While capturing the image of the alarm event, it also pioneered the storage, search and playback functions of the â€œfirst 3 and 5â€ second video streams of the alarm event.

The key points of the prison's access: through the high-definition camera to the personnel and vehicles entering and leaving the prison to automatically extract license plates, faces. And store data, pictures, video stream information, for the supervision and management personnel to check and check. It can also improve the efficiency of post-mortem verification work.

In addition, while the detainees are being managed, the system can also be used to improve the management of the supervisors and supervisors. For example, the system can automatically record the patrol time and route of the patrol personnel; the person who automatically captures the inspection personnel Faces to avoid stealing beams and so on.

Second, the construction goals and design ideas

The goal of the prison safety technology prevention system is to make full use of the existing resources of the prison, through the transformation and upgrading of the original security system, using advanced computer intelligent vision technology and data integration and integration technology to build video surveillance, intelligent automatic alarm, The multi-level, all-round and three-dimensional prison digital security system and emergency command system, which integrate supervision, management and intelligent dispatching, achieve the goal of strong prison security, fair and law enforcement, and efficient command and management. With the support of modern information technology, the construction of a prison information framework system covering the network interconnection and intercommunication, information resource sharing, standardization and standardization, and complete application functions of the whole monitoring area. It lays a solid foundation for the standardization of prison information construction and the sharing of information resources for the national judicial system. In the specific design, two main ideas must be followed:

"Application integration, a platform"

With the high-level equipment integration of the unified application of each subsystem as the direction, through the development and application of the data integration platform, on the unified integrated application platform, realize the corresponding excuses for the systems such as the access control system and the interview system. The software enters the integrated application platform, and the distributed system including the OA and the prison management system outside the security system is also centralized into the system. At the same time, the open interface is reserved for the new application system that may appear in the future, and is compatible with future applications. Data and management software. Achieve centralized management of all systems and equipment and unified platform entry, so that operators or managers can realize the intervention and application of various information systems in the prison under a unified interface.

"Intelligent reuse, linkage support"

Intelligence is the development trend of security systems. In recent years, the product development and application of intelligent technology has advanced by leaps and bounds. In addition to the most advanced intelligent video analysis technology based on computer vision, the concept of â€œlogistics networkâ€ is the forerunner and based on RFID technology. Wireless wristband positioning technology also has broad prospects in prison applications. Through the development of a data integration platform, various possible alarm modes in the prison will be centralized to form a complete linkage mode, providing a rich linkage control function for the prison command center and the sub-control center, and constructing the nerve center and command system of the prison system. In order to improve the quality of emergency response plans for prison emergencies, it is effective to prevent human error from providing a strong guarantee for major cases.

Third, the intelligent monitoring system construction program

The intelligent video surveillance system is a software system that relies on the network to realize the management and control of all monitoring equipment and services in the equipment room, and has the function of interacting with the prison system and the OA system.

The system includes a dedicated video management server, a data management server, and a client. The video management server is a dedicated signaling server for centralized authentication, registration, configuration, control, and alarm forwarding control, and can implement a complete network coding and decoding device video management function. Support multiple signaling management servers to work together to form a multi-level and multi-domain management system. The main function of the data management server is to manage storage devices, storage resources and video data. It supports all-round monitoring and management of all storage resources of the system, and supports uninterrupted video retrieval and playback. The client can provide friendly and convenient human-machine interface functions, including real-time monitoring and monitoring of monitoring objects, query, PTZ control, alarm processing, and integrated basic GIS functions for user operation.

Intelligent video surveillance system function introduction

According to the intelligent needs of prisons, combined with the particularity of climatic conditions in certain areas, in this construction, intelligent video analysis system is mainly applied to perimeter prevention, so the main functions of intelligent video analysis are perimeter defense and face recognition. , regional prevention and control, flaw detection, off-the-job detection, video anomalies, etc.

Perimeter defense

The wall is the key prevention area of â€‹â€‹the prison or labor camp. In order to prevent the prisoner from jailbreaking, when a person approaches the wall, the system alarms the command center personnel to pay attention, and simultaneously links the voice equipment on the scene to prevent the prisoner from escaping. When the moving target appears over the prompt line, the alarm line or enters the warning area, the system triggers a preset alarm mechanism to prompt or alarm, and automatically uploads the alarm screen, automatically pops up the image, and pans the lens through the intelligent video integrated management platform. Look at and automatically call the sound and light alarm device in the actual scene to perform stereoscopic linkage processing such as alarm.

Regional intrusion detection

Through the intelligent video analysis system to monitor important areas, multiple arbitrary shape areas can be set in the video screen for arming, and the area detection function is enabled. When there is a moving target "enter" or "leave" the surveillance area, enter from any direction. When it leaves, it can trigger an alarm. The main application is to prevent the prison perimeter and form an electronic wall with the electronic fence system to achieve strict control over the perimeter of the prison.

Face recognition detection

The face recognition technology is based on the biometric technology of human facial image information. By analyzing the face of the video, the face is compared with the face feature database to achieve the purpose of identifying and identifying different people. The face recognition door is installed in the two AB doors of the prison, and the face recognition + IC card joint verification is performed on the entering and leaving personnel.

Parabolic (moving, detention) detection

Parabolic detection is provided in important areas such as walls or windows. When items are thrown from other areas into the set area, the system alarms to prevent theft and deliver the items through abnormal channels.

Personnel aggregation test

Within the scope of the scene monitored by the camera, the system calculates the density of the personnel in the alert area, and dynamically outputs the number of personnel. When a certain field value is exceeded, a prompt or alarm is triggered. It is used in sensitive areas of prisons and in areas with frequent incidents of incidents. It handles the police at the first time and avoids the expansion of the situation.

å¾˜å¾Š detection

The intelligent video analysis system monitors important areas of the prison room, and enables the area detection function in the video screen to trigger the system report when there is a moving target within the area for more than a certain time limit.

Detachment detection

In the prison command center, the gate duty room, the middle door duty room, the supervision area duty room, etc., the off-the-job detection function is applied to realize the supervision and management of the off-duty police on duty. When the duty officer is out of work for more than the set time, the system alarms and uploads the live video. Command center.
