Industry Status
In January 2019, the General Office of the State Council issued the Guiding Opinions on the Comprehensive Implementation of the Administrative Law Enforcement Publicity System, the Law Enforcement Full Process Record System, and the Legal Review System for Major Law Enforcement Decisions, which put forward clear requirements for the work related to the comprehensive implementation of the administrative law enforcement publicity system, the law enforcement full process record system, and the legal review system for major law enforcement decisions. Law enforcement recorders have since become standard equipment for law enforcement activities in public security organs.
In the daily work of front-line police officers, there is a current situation of "too much equipment and heavy burden", which urgently needs to be equipped with intelligent law enforcement terminals and a comprehensive command platform based on the principles of "reducing the burden on the grassroots, increasing efficiency on the basis, empowering practical combat, and guiding service".
Build an intelligent comprehensive command and dispatch system with law enforcement recording equipment as the contact point, focusing on business such as "standardized law enforcement, service supervision, major security, counter-terrorism and emergency response".

The system has the qualification of information security level three protection. Protective wall devices are deployed at the network boundary to provide access control services for the information system, and intrusion prevention devices are deployed to provide security protection services for the application system.
Adopting J2EE technology architecture provides a good mechanism for building scalable, flexible, and easy to maintain business systems.
According to different storage requirements, the middleware used is divided into Redis services for memory storage and MySQL services for permanent storage, enabling the system to support higher concurrency.
Adopting a layered architecture design to achieve high cohesion and low coupling, with better disaster recovery capabilities.
The system uses group codes to distinguish between various units and departments, and adopts a top-down permission management approach.
The platform supports GB28181 standard protocol and RTMP protocol access to achieve video fusion.
Platform Function Overview
Supporting intelligent analysis, it can perform big data statistical analysis on trajectory, upload, and login, and dynamically display it on a large screen.
Based on functions such as voice communication, video feedback, and real-time positioning, achieve "call to call, visible, and adjustable".
Intelligent interactive experience enables easy video classification, video review, and video analysis.
The system interface is open, allowing for deep coupling with the actual business content of the enterprise, and customized development to meet the functional requirements of the enterprise's own application scenarios.

Hailian High Availability Architecture Solution
Audio and video data transmission scheme for public security intranet
The operator establishes a VPN dedicated wireless network channel for wireless transmission of mobile law enforcement terminals.
Deploy the Hailian platform (streaming/signaling services, etc.) in the VPN dedicated network to achieve real-time feedback of mobile law enforcement terminal positioning, video and other data.
Establish a one-way video stream transmission channel between the VPN private network and the public security video private network using a dedicated switch.
The Hailian server uses a forwarding service to convert the video uploaded by law enforcement terminals into a standard GB28181 video stream, which is then transmitted to the video private network through a dedicated switch. The video system within the private network can store and apply related business applications.
The video private network transmits real-time audio and video streams to the public security intranet centralized management platform through cascading security gateways, thereby achieving unified application of the intranet centralized management platform.

Inspection and patrol function
On-Site Inspection
Patrol tag cards, frontline personnel can report tag information by swiping NFC cards through smart terminals.
Inspection supports various scenarios such as disorderly inspection, orderly inspection, and timely inspection.
The inspection label card adopts IP65 technology, has positioning holes, comes with 3M double-sided tape, and can be used outdoors.
The inspection clock in function is suitable for inspection application scenarios where indoor GPS signals are weak and clock in by floor.
patrol
Set patrol points on the map, and frontline personnel can clock in and report upon arrival at the patrol points.
Patrol supports various scenarios such as disorderly patrol, orderly patrol, and on-time patrol.
Suitable for patrol application scenarios where outdoor check-in points are far apart, such as grasslands, forest farms, etc.
Patrol points allow for accuracy errors, therefore each patrol point has an accuracy range.
Scene recording function
The law enforcement recorder can provide users with customized recording of specific work content according to the scene,The saved video file name contains specific characters to achieve video file taggingIt is convenient for quick video retrospective analysis.
Scene recording is suitable for video analysis scenarios, when it is necessary to target different law enforcement activities of frontline police officersPlays a significant role in the association of legal cases and the standardization of law enforcement inspections.
