Safe City is the goal of urban security construction in China in recent years. How can we achieve this goal? HD intelligent video surveillance is the foundation of Safe City's security business. Here we introduce the composition, characteristics, and functions of the high-definition intelligent video surveillance system.

System Overview With the development of economy and the speed of urban construction, the density of population and the increase of floating population in urban areas have caused many urban management problems such as traffic, social security, and prevention in key areas in urban construction. The increase in public security police forces is far from satisfactory. The speed of actual demand. In order to combat all kinds of economic criminal crimes, protect the life and property security of the country and the people, ensure the normal operation of all walks of life and all sectors of society, and use high-tech means to prevent and stop all kinds of crimes from becoming the development direction of security prevention, As an important technical precautionary measure, video surveillance has been more and more widely used.

Pingan City's video surveillance system is mainly applied video processing technology and transmission technology to conduct real-time monitoring of public security dynamics in large gathering places, complex security areas, important units and other parts, discovering criminal activities in a timely manner, using surveillance video data to verify criminal clues, Real-time monitoring of on-site dynamics of large-scale events and mass incidents, realizing the integrated application of surveillance image information and other information, and improving public security agencies' services in managing public security situations. In the end, the prominent issues of social security in urban areas were basically solved, the security environment was significantly improved, and the people’s sense of security continued to increase.

System composition The safe city HD intelligent video monitoring system mainly involves audio and video acquisition, transmission, storage, management, sharing and other links. The entire solution can be divided into front-end monitoring resource collection, monitoring resource access, networked centralized management platform, image resource storage, and image resource sharing platform construction. The front-end video collection mainly includes: road bayonet, red street intersection, hotels, entertainment venues, cybercafes, city streets, police station detention rooms, and other public areas. In these key areas, millions of high-definition network cameras are installed to implement high-definition on-site monitoring. , capture, intelligent analysis; to enable relevant management departments to fully grasp the details of the scene, to provide high-quality screen to the monitoring staff or back-end intelligent analysis system, in the completion of the traditional post-event analysis function, while gradually implementing advance warning tips. In each area, a front-end high-definition monitoring subsystem is built to complete detailed recording and monitoring of each area. At the same time, each subsystem is integrated into a private network through a video fiber private network to implement high-definition centralized urban high-definition video surveillance to achieve unified scheduling. Sharing, improve the efficiency of the relevant law enforcement agencies. At the same time as the video surveillance, the command center can simultaneously evangelize (broadcast) multiple front ends and provide voice assistance to help-seekers. It can act as a deterrent to crimes committed by criminals, achieve visible control, and promote harmony and prosperity for the city. Build a high-definition video security monitoring network.

Social security monitoring is monitored at the gates of government agencies, at the gates of financial institutions, administrative agencies, densely populated areas, important transportation areas, complex environmental sites (squares, theaters, entertainment venues, railway stations, hotels, restaurants, parks, etc.), and urban roads. Fixed intersections are monitored by high-definition camera guns, and high-definition network domes are used to implement large-scale surveillance, so that security monitoring personnel can more accurately and timely detect and track alarms and improve response speed.

The transmission network adopts the “cable-based, wireless-assisted” construction mode, focusing on cost control and access quality, and focuses on the point-to-point and network management access modes. The wired mode uses self-built fiber access or leased line access; wireless access uses 3G or WIFI.

The monitoring center consists of management server, streaming media server, storage server, intelligent analysis server, client, HD decoding matrix, large-screen video wall, etc. It can monitor and control multi-monitoring front-ends under unified operation platform and unified interface. Features.

Webcasts are installed in public security complexes, important intersections, plazas, communities, and other security monitoring sites. Based on the installation of network cameras for video surveillance, audio equipment such as pickups, IP network broadcasting, and horns are installed, as well as emergency help buttons and alarm probes. The broadcasting terminal transmits the above signal to the public security bureau command center through the monitoring private network, and configures the network microphone and the speaker at the command center, so that the audio and video alarm linkage function can be realized. That is, the command center can simultaneously perform single or multiple simultaneous video monitoring. Front-end propaganda (broadcasting) can provide voice assistance to help-seekers, and can act as a deterrent to offenders' criminal acts to reduce the crime rate.

High-definition bayonet installs the high-definition security security bayonet system on interprovincial, intercity, urban arterial roads, major traffic arteries, and main entrances and exits, captures all vehicles passing through, obtains vehicle images, and automatically recognizes the license plate characters in real time. Record the time, location, license plate number, driving direction and other data of the vehicles passing through, and all of them are imported into the network transmission subsystem and transmitted to the central management platform. The platform can compare front-end uploaded pictures with the blacklist library in real time, and discovers that the vehicle is alerted through software interfaces, sounds, and text messages after the vehicle is controlled; the system can perform single-condition query and combination query according to license plate, location, lane, time, and other information. And fuzzy inquiries; the system can be based on day, week, month, year and other time periods, statistics of different points, different equipment, vehicle information, and reports, graphs, charts and other intuitive ways to display.

High-definition electronic police use 140/200/500 million CCD high-definition integrated cameras for the collection of the main body, a single camera covering one-way lanes 1-3; simultaneous support for flash and LED strobe lights for night fill light. The system can automatically judge three consecutive violations of traffic safety violations in the vehicle by judging the intelligent analysis of the video to determine whether the vehicle is running red light, right/left turn, reverse driving, pressure line, cross line, or violation of prohibited lines. Violation pictures and illegal photos can clearly reflect the basic situation of illegal vehicles such as "red light, parking line, vehicle type, license plate, time and place". The system is capable of organic integration of people, roads, and vehicles. It fully applies the red light recording system to make traffic monitoring truly "intelligent", greatly improving the efficiency of traffic management and ensuring traffic safety.

Social resources access In order to increase the monitoring of important public security and complex places, strengthen the management of key public security units and internal units of the Ministry of Public Security, improve the ability of public security agencies to discover, control, deter, and crack down on all types of illegal and criminal activities, and improve the city’s society. The overall level of public order prevention requires the organic integration of a large number of social resource monitoring systems to achieve unified management and resource sharing. Social resource monitoring includes: important traffic intersections, road sections; head offices, key parts, public complexes, places for personnel gathering; Internet cafes, entertainment venues; hotels, hotels; civil explosives storage and use units; internal security units; residential communities; public security grassroots Units; public security institutions; GPS monitoring of special vehicles.
