Safe City HD Intelligent Video Surveillance Solution

1.1 System Overview

With the development of the economy and the speed of urban construction, the population density and the floating population in the city have increased, which has led to many urban management problems such as transportation, social security, and prevention of key areas in urban construction, and the increase in public security police force is far from meeting actual needs. speed. In order to combat various economic and criminal crimes, protect the lives and property of the country and the people, ensure the normal operation of all walks of life and all sectors of society, and adopt high-tech means to prevent and stop various crimes from becoming the development direction of security. Video surveillance has become more and more widely used as an important technical defense.

Ping An City video surveillance system mainly uses video processing technology and transmission technology to monitor the security situation of large gathering places, complex security areas, important units and other parts in real time, timely discover illegal and criminal activities, use surveillance video data to verify criminal cues, Real-time master the dynamics of large-scale events and mass emergencies, realize the comprehensive application of monitoring image information and other information, and improve the public security organs to control the social security situation. In the end, the outstanding problems 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.

1.2 System components

Ping An City HD intelligent video surveillance system mainly involves the collection, transmission, storage, management and sharing of audio and video. The whole 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. Front-end video capture mainly includes: road bayonet, red street junction, hotel hotel, entertainment venue, Internet cafe, city street, police station detention room, other public areas, etc., installing high-definition Network Cameras in these key areas to implement high-definition on-site monitoring , capture, intelligent analysis; enable relevant management departments to fully grasp the details of the site, provide high-quality pictures to the monitoring staff or the back-end intelligent analysis system, and gradually realize the pre-warning prompts while completing the traditional post-analysis function. Each area builds a front-end HD monitoring subsystem to complete detailed recording and monitoring of each area. At the same time, each subsystem is integrated into the private network through the video fiber-optic private network to realize high-definition video surveillance in large-scale centralized cities, achieving unified scheduling and resources. Sharing and improving the efficiency of relevant law enforcement agencies. At the same time of video surveillance, the command center can simultaneously call (broadcast) multiple front-ends, provide voice help to help-seekers, and act as a deterrent to criminals' crimes, realize visible control, and achieve harmony and prosperity for the city. Build a high-definition video security monitoring network.

1.2.1 Social Security Monitoring

Monitoring at the gates of government agencies, financial and administrative agencies, densely populated areas, traffic routes, complex environmental sites (plazas, theaters, entertainment venues, stations, hotels, parks, etc.), urban roads, etc. The high-definition camera gun is used for monitoring, and the moving point adopts the high-definition network ball machine to implement a wide-range monitoring, so that the security monitoring personnel can find and track the alarm more timely and accurately, and improve the response speed.

The transmission network adopts the "wire-based, wireless-assisted" construction mode, focusing on cost control and access quality, with the idea of point-to-point and network management access mode. The wired mode adopts self-built optical fiber access or leased private line access; the wireless access adopts 3G or WIFI.

The monitoring center is composed of a management server, a streaming media server, a storage server, an intelligent analysis server, a client, a high-definition decoding matrix, a large-screen video wall, etc., and can realize monitoring and control of the multi-channel monitoring front end under a unified operation platform and a unified interface. Features.

1.2.2 Webcast

In the public security complex areas, important intersections, plazas, communities and other public security monitoring sites, on the basis of installing network cameras for video surveillance, install audio equipment such as pickups, IP network broadcasts, horns, etc., as well as emergency help buttons, alarm probes, via network broadcast terminals. By monitoring the private network to transmit the above signals to the command center of the Public Security Bureau, and configuring the network microphone and speaker in the command center, the audio and video alarm linkage function can be realized, that is, the command center can simultaneously call the single or multiple front ends while monitoring the video. (Broadcast), it can provide voice help to help-seekers, and can act as a deterrent to criminals of criminals to reduce crime rate.

1.2.3 HD card slot

By installing high-definition security bayonet systems in provincial, intercity, urban main roads, main traffic routes, main entrances and exits, all vehicles passing through are captured, vehicle images are obtained, and license plate characters are automatically recognized in real time, and vehicles are recorded. Data such as time, place, license plate number, and driving direction are all transferred to the network transmission subsystem and transmitted to the central management platform. The platform can compare the pictures uploaded by the front end with the blacklist library in real time, and find out that the vehicle is controlled by software interface, sound, SMS, etc. after the vehicle is controlled; the system can perform single condition inquiry and combined inquiry according to the license plate, location, lane, time and other information. And fuzzy query, etc.; the system can count the vehicle information of different points and different devices according to the time of day, week, month, year, etc., and display them in various intuitive ways such as reports, graphs, and histograms.

1.2.4 HD Electronic Police

The 140/200/5 million CCD high-definition integrated camera is used as the main body of the acquisition. The single camera covers one-way 1~3 lanes; the synchronous flash and LED strobe light are synchronized to fill the light at night. The system can judge the vehicle's straight traffic red light, right/left turn, reverse driving, pressure line, over-line, violation of the prohibited line and other illegal behaviors through intelligent analysis of the video, and can automatically detect three consecutive violations of the traffic safety law. Violation of the picture, illegal photos can clearly reflect the "red lights, parking lines, models, license plates, time, location" and other illegal vehicles. The system achieves the organic combination of people, roads and vehicles, and fully applies the red light recording system to make traffic monitoring truly “intelligent”, greatly improving the efficiency of traffic management and ensuring traffic safety.

1.2.5 Social resource access

In order to increase the monitoring of important public security complex sites, strengthen the management of key public security units and internal units of the Ministry of Public Security, improve the ability of public security organs to discover, control, stop, and combat all kinds of illegal and criminal activities, and improve the overall level of social security in the city. It is necessary to organically integrate a large number of social resource monitoring systems to achieve unified management and resource sharing. Social resource monitoring includes: important traffic intersections, road sections; summit organs, key parts, public complex, personnel gathering places; Internet cafes, entertainment venues; hotels, hotels; units for the storage and use of civilian explosives; internal insurance units; residential quarters; Unit; public security bureau; special vehicle GPS monitoring.
