Background of program construction

Law Enforcement Recorder is a kind of scientific and technological law enforcement product developed rapidly in recent years, and it is also a kind of police equipment which is concerned by the public security system all over the country. Law Enforcement Recorder set of digital photography, photography, audio recording and other functions in one, can be on the law enforcement process of action, static and objective records. At present, the law enforcement recorder can not only effectively promote the police to enforce the law in a normal, just and civilized manner, but also effectively safeguard the police‘s legitimate rights and interests. But while most existing law enforcement recorders can record audio and video of the scene, they can not transmit images in real time, nor do they have global GPS or Beidou positioning, it can not cooperate with the back-end monitoring, dispatching and commanding platform system to realize the remote dispatching and commanding function for outdoor mobile individuals.

To build a 4G/5G visual command and dispatch system, to realize the global positioning of the police while on duty, 4G/5g wireless graph transmission function, and to record video and audio on the spot, and upload the recorded data to the system database, it can realize the functions of storage, cataloging, retrieval, management, examination, research and judgment, etc. . Compared with the traditional recorder, the 4G/5G intelligent law enforcement recorder can transmit the video in real time, which is helpful for the remote dispatch and the real-time inspection of the scene, and makes the law enforcement more convenient and the command dispatch more powerful, will further promote the regularization of the team, law enforcement standardization, effectively enhance the police‘s law enforcement credibility.

Based on the background of the law enforcement industry, the requirements of the visual command and dispatch system of the law enforcement of the public security system were investigated in-depth. The requirements were as follows:

Real-time control: the leadership of remote supervision and management, through monitoring and command platform, synchronization of 4G/5G law enforcement recorder voice, video on-site situation, real-time control of on-site law enforcement process, results, enhance the level of law enforcement management;

Standardized law enforcement: cross-regional and cross-level law enforcement information inquiry, transfer and statistics, effective control of law enforcement officers on the scene of law enforcement, standardize the law enforcement process, to play the value of law enforcement information.


Visualization of law enforcement: to display the information of law enforcement personnel and their location through geographic information map, so as to enhance the overall control ability of the command center.

Fixed evidence in time: due to the law enforcement recorder with synchronous audio and video recording function, for some of the sudden illegal facts can be fixed timely evidence, on-site law enforcement is crucial.

Coordinated Command: in the event of a major incident, the platform provides a flexible means of dispatch, the command centre personnel can direct command of front-line personnel, civilian police on duty on the front line can report directly to the command centre as needed, can also be live video back to the commander, to achieve flat command of emergency operations.

Improve the efficiency of disposal: through 4G/5G law enforcement recorder can real-time transmission of the scene to the command center, to facilitate the command center staff to conduct timely research and disposal, improve the overall efficiency of law enforcement.

Prevention of non-compliance law enforcement: Command Center personnel through 4G/5G remote control real-time access to duty personnel scene, the formation of invisible supervision deterrent, to ensure the implementation of public justice, to eliminate human relations law enforcement.


Improve public satisfaction: the command center can real-time access to 4G/5G law enforcement terminal video and audio, in law enforcement in the face of the people pay attention to words and deeds, pay attention to attitude, let duty personnel to maintain a rational, smooth, civilized, standard law enforcement process, and improve the people‘s satisfaction.


Effective Protection of officers on duty: in case of non-cooperation with law enforcement, the front-line law enforcement police can truthfully restore the situation on the scene after the event by recording the whole process of the incident, to protect the rights and interests of frontline law enforcement police to provide effective evidence.



Visual Law Enforcement Command and dispatch system framework

Hua Mai Zhi Lian 4G/5G visual command and dispatch system is integrated with video, voice and data services, it provides a multi-function platform for voice scheduling, trunking, video conference, audio and video monitoring, audio and video on demand, live broadcast, data upload, data forward, short message, service data application, GPS positioning and tracking, etc. .


Advantages and characteristics of the scheme

1.Real-time video

Dispatchers can remotely turn on the phone‘s side camera and start recording video, sending the video back to the platform in real time. Through this function, the platform can satisfy the fact monitoring of the scene of the incident, and according to the monitoring process through the intercom on-site implementation strategy, the video will become a historical preservation, to meet the need for evidence preservation.

Mobile launch video back: Mobile Launch Video Back Channel members can view the video, and in the scheduling platform can real-time view this video.


The platform requires the mobile phone to initiate video playback: the platform dispatcher can make a user‘s phone start recording video, and in the scheduling platform can view the video.



2.Law enforcement intercom system

In the process of dealing with emergencies need to communicate with the command center, emergency also need to quickly report to the police and upload relevant materials such as audio, video, pictures, etc. , at the same time, the command center needs to supervise the process of dealing with the emergency, to know the working status and location of the rescuers in real time, and to dispatch the emergency in order to control the whole process of dealing with the emergency. In addition, rescue workers also need to carry out real-time communication, in order to facilitate the emergency situation and the surrounding situation of the timely understanding.


3. Flat Command and dispatch based on GIS

Member location, real-time display,

historical track, online query,

one-click Circle selection, Rapid Command

GPS/Beidou/AGPS positioning

1) track playback


At a particular time, due to some events, the dispatcher may need to extract and analyze the trajectory of a user during this time, so that the scenario, the track playback feature addresses this need. After you select the start and end times, the user‘s track is displayed on the map. In the data area, you can also view the component points of the track, each point contains the details of the time, and the reporting time is satellite positioning or base station positioning, as well as the address of the point, at the same time, the point can be viewed on the map.

2) electronic fence

It is mainly used to control the daily work area of the mobile phone users, because the dispatcher can not pay attention to every working user on the screen 24 hours a day, then the electronic fence will become an early warning platform for violation of the rules of the work area. From the perspective of regularity, the electronic fence supports the prohibition of entry and exit.


3) circle the call

To facilitate scheduling, users can circle the map, and then circle the selected area of the online user to call.



4.Multimedia IM

Dispatchers can interact with field workers based on group or peer-to-peer multimedia messaging, including voice, video, text, pictures, and location. Through more interactive forms of rapid remote consultation, and can be used as a basis for later verification.
