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

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.
