1.Background of scheme construction
Law enforcement recorder is a rapidly developing technology law enforcement product in recent years, and it is also a police equipment widely concerned by public security systems in various regions. The law enforcement recorder integrates functions such as digital camera, photography, and recording, and can objectively record the law enforcement process in action and static state. At present, law enforcement recorders can effectively promote standardized, fair, and civilized law enforcement by police officers, while also effectively safeguarding their legitimate rights and interests, becoming a "weapon" for frontline police officers at the grassroots level to carry out law enforcement work. However, although most existing law enforcement recorders can record on-site audio and video, they cannot transmit real-time images, nor do they have global GPS or BeiDou positioning, and cannot collaborate with backend monitoring and dispatch command platform systems to achieve remote dispatch and command functions for outdoor mobile individuals.
2.Customer needs in the law enforcement industry
Build a 4G/5G visual command and dispatch system to achieve global positioning and 4G/5G wireless image transmission functions for police officers during duty, and record video and audio on site. The recorded data can be uploaded to the system database for storage, cataloging, retrieval, management, assessment, and judgment functions. Compared with traditional recorders, 4G/5G intelligent law enforcement recorders can transmit captured images in real time, which helps remote dispatch and real-time viewing of on-site situations, making law enforcement more convenient and effective. This will further promote the regularization and standardization of law enforcement teams and effectively enhance the credibility of police enforcement.
Based on the background requirements of the law enforcement industry, Huamai Zhilian conducted in-depth research on the demand for a visual command and dispatch system for law enforcement in the public security system. The requirements are summarized as follows:
Real time control: The leadership remotely supervises and manages, synchronizes the on-site situation of the 4G/5G law enforcement recorder‘s voice and video through the monitoring and command platform, and real-time controls the on-site law enforcement process and results, improving the level of law enforcement management;
Standardized law enforcement: The query, retrieval, and statistics of cross regional and cross level law enforcement data, effectively controlling the law enforcement situation of frontline law enforcement personnel, regulating the on-site law enforcement process of law enforcement personnel, and leveraging the value of law enforcement data.
Visualization of law enforcement duty: Through geographic information maps, the information and distribution of duty personnel within the jurisdiction are visually displayed, comprehensively enhancing the overall control ability of the command center.
Timely fixation of evidence: Due to the synchronous recording and recording function of law enforcement recorders, it is crucial to collect and fix evidence in a timely manner for some sudden illegal facts in on-site law enforcement.
Collaborative command: In the event of a major event, the platform can provide flexible scheduling methods. The command center personnel can directly command frontline personnel, and frontline duty police officers can report directly to the command center as needed. They can also transmit real-time on-site videos back to the commander, achieving flat command of emergency operations.
Improving disposal efficiency: By using 4G/5G law enforcement recorders, the on-site situation can be transmitted in real-time to the command center, facilitating timely analysis and disposal by command center personnel, thereby improving overall law enforcement efficiency.
Prevention of non compliant law enforcement: Command center personnel use 4G/5G remote control to access real-time on-site footage of duty personnel, forming an intangible regulatory deterrent force, ensuring the transparency and fairness of enforcement, and preventing human relations law enforcement.
Improving public satisfaction: The command center can access real-time video and audio from 4G/5G law enforcement terminals, pay attention to words, deeds, and attitudes towards the public during law enforcement, and enable duty personnel to maintain a rational, gentle, civilized, and standardized law enforcement process, thereby improving the satisfaction of the people.
Effective protection of duty personnel: Frontline law enforcement officers can provide effective evidence for protecting the rights and interests of frontline law enforcement officers by recording the entire process of the incident and truthfully restoring the on-site situation afterwards.

4. Advantages and characteristics of the plan
Dispatchers can remotely turn on the camera on their mobile phones and start recording videos, which can be transmitted back to the platform in real time. Through this function, the platform can monitor the facts of the event scene and execute strategies on the scene through intercoms based on the monitoring process. The video will be preserved as history, meeting the need for evidence retention.
Mobile initiated video feedback: After the mobile initiated video feedback, all members in the channel can view the video and view it in real-time on the scheduling platform.
The platform requires the mobile end to initiate video feedback: the platform dispatcher can allow a user‘s mobile phone to start recording videos and view the videos on the scheduling platform.
B.Law Enforcement Intercom System
In the process of handling emergencies, it is necessary to communicate with the command center. In emergency situations, it is also necessary to quickly report to the police and upload relevant materials such as recordings, videos, pictures, etc. At the same time, the command center needs to supervise the process of handling emergencies, understand the work status and geographical location of rescue personnel in real time, and command and dispatch emergency situations to facilitate the control of the entire disposal process. In addition, real-time communication between rescue personnel is also necessary to facilitate timely understanding of the dynamics of emergencies and surrounding conditions.

GPS/Beidou/AGPS positioning
1) Track playback
In a specific period of time, due to certain events, dispatchers may need to extract and analyze the action trajectory of a user during this period. In such a scenario, the trajectory playback function can solve this need for you. After selecting the start and end times, the user‘s trajectory will be displayed on the map. In the data area, you can also view the composition points of the trajectory, each point containing detailed time, whether it was satellite positioning or base station positioning when reporting, and the address of this point. At the same time, this point can also be viewed on the map.
2) Electronic fence
Mainly used for controlling the daily work area of mobile phone users. As dispatchers cannot pay attention to every working user on the screen 24 hours a day, the electronic fence becomes a warning platform for violating work area rules during work. From a regulatory perspective, the electronic fence supports prohibition of entry and exit.
3) Circle call
For the convenience of scheduling, users can call online users in the selected area by drawing circles on the map.
D. Multimedia IM
Dispatchers can interact with on-site staff through group or peer-to-peer multimedia messaging, including voice recording, video recording, text, images, and location. Remote negotiation can be quickly carried out through more interactive forms, which can also serve as a basis for later verification.
E. File playback function
Select "File Playback", the file types are divided into: video file, audio file, and stored image. The video playback function is divided into two types: server cloud recording and PC client computer local recording, and is displayed in the form of "thumbnails" by default.
F. SOS linkage alarm function
When an emergency occurs, the SOS button defined on the intelligent terminal can be operated with one click to report one‘s real-time video and location to the command center and sound the alarm horn. The command center dispatch center will immediately see the video and accurate location of the law enforcement officer. Other members of the same group will also receive real-time alarm and distress messages from the individual, and be able to know the GIS location of the team member in real time. They can navigate to the scene based on the map to provide rescue support.
G. Video live streaming forwarding function
Real time live streaming of work site videos through 4G intelligent terminals, supporting multi-level scheduling stations and other mobile terminals to view the live video, and establishing multi-party conference calls for discussion and issuing commands. In video live streaming mode, it is possible to switch between a certain real-time feedback video as the main video source and forward the video to other mobile terminals for live streaming, suitable for video negotiation and combat collaboration purposes.
