1、 System Overview

In order to effectively improve the overall quality of the city22The public security bureau of a certain city has decided to carry out the construction of social security monitoring and network management throughout the city to improve the quality of social security work in various districts and counties. According to the requirements of the Municipal Public Security Bureau, the social units that are required to be connected to the city's public security video surveillance management system that has been put into construction include hotels, restaurants, internet cafesKTVMultiple industries including cinemas, bathing, seal carving, mechanical repair, and waste recycling. In order to reduce duplicate investment, it is required to preserve the existing devices of front-end users as much as possible when constructing the system, and achieve a large-scale network for video management. Based on this, we propose a comprehensive solution for public security video surveillance that is compatible with multiple devices and has multi-level video networking. We strive to achieve compatibility with existing hard disk recorders, video servers, network cameras, capture cards, etc. for front-end users. This not only enables local management of videos, but also uploads them to various district and county control centers for unified monitoring, which is then cascaded between the servers of each control center and the city control center. The video stream is forwarded from front-end users to the district and county public security bureaus, and then forwarded to the municipal public security bureau's security detachment for secondary transmission. The security detachment macroscopically regulates the entire system, and the overall project is a three-level video networking system architecture.

The key functions of the city's public security monitoring network management system are as follows:

1.The city control center can view real-time videos of all front-end users, and videos from various regions can be combined arbitrarily on the display screen of the control center. It can also adjust the cloud mirrors of all front-end devices at will.

2.Most front-end users adoptADSLGo online and focus on solving dynamic issues when connectedIPThe difficult problem.

3.Unified management of alarms, displaying alarm information for front-end users in a unified manner, where the names, addresses, detailed locations, contacts, and phone numbers of each alarm point can be seen at any time for quick processing.

2、 Advantages of Xinrongquan Social Security Monitoring System

1.True implementationThree level networking for video surveillance, where front-end users can manage local videos. County and district public security bureaus will establish sub control centers, deploy center server software, and implement 24/7 monitoring of all videos within their jurisdiction. The Municipal Public Security Bureau has set up a central control center, deployed a central control center server, and implemented three-level video management after installing the central server software.

2.successCompatible with various existing hardware devices, focusing on the principle of economy, the Municipal Public Security Bureau has requested to be as compatible as possible with existing hardware devices, including hard disk recorders, video servers, network cameras, and video capture cards. In order to reduce the workload of pre-sales and after-sales, the compatibility mode of global eye flashing compatibility should not be used. After investigation, it was found that5000Among users, there are nearly a hundred device brands, making compatibility quite difficult. My platform was originally compatible with hardware such as Hikvision, Dahua, Hanbang, Langchi, Hengyi, Carl, etc. Based on this, we have made direct installation and configuration for users using the above brands. The remaining devices are classified as common brands and obtained from manufacturersSDKThen proceed directly to secondary development. According to user requirements, a small amount is neither available nor availableSDKAnother very common brand directly exchanges equipment.

3.Resolve dynamicsIPThe challenge of difficult networking is that most front-end users are from traditional industries, usingADSLOnline, in this network situation, it is necessary to solve the dynamic problem of video networking with the sub control centerIPThe difficult problem. In traditional solutions, domain name resolution is generally used to bind dynamicsIPThis' active cow '. Xinrongquan Software Company organized senior R&D engineers to focus on technical development and successfully solved the problemADSLThe problem of directly connecting to the network control center avoids5000The workload of domain name resolution,This kind of penetrationADSLThis technology is the first to appear in China and is a leading technology in the industry.

4.Powerful functionality and simple interface, in order to make grassroots users use and make good use of the security video surveillance system, we must take them seriouslyITIn the reality of a lack of knowledge, an excellent platform not only needs to achieve powerful video networking, but also needs to make it easy for all users to use. This system simplifies all complex operations, making it easy to understand with a single click and avoiding two-step operations. Whenever possible, try to make the system autonomous and set non essential settings and operations to run automatically.

5.Meeting the needs, assisting in operations, and providing security video surveillance systemsThe purpose is to achieve security monitoring management and maintenance under digital video through technological innovationSocial order ensures the safety of citizens.Therefore, the primary requirement of the project is to meet the business needs. We consider hotels, innsKTVInternet cafes and other places have high population mobility and are prone to disputes and conflicts. It is best for these users to have real-time business communication with the center. System DesignDeveloping important functions such as identity card recognition and comparison, real-time video retrieval, multiple alarm methods, and alarm information,When a user reports an alarm, the user's name, business type, address, contact person, phone number, detailed location, etc. can be uploaded to the sub control center with just one click. During rest time, the information can also be automatically sent to the mobile phone of the police officer in charge, greatly reducing the time for reporting and responding to the alarm. Technology supports business, system ensures safety.

6.Good scalability, the average video access in each county during project implementation is200To facilitate the access of more front-end users, the system must maintain good scalability. The Xinrongquan video surveillance platform adopts automatic integration technology, which reserves huge space for the increase of later users. At the same time, during the second phase expansion, the sub control center does not need to make any modificationsAll added front-end users are automatically integrated into the control system. In addition, interfaces have been reserved for connecting with the Provincial Public Security Department.
