Ruizhang solution:

1. The private network  4G multimedia dispatching system, can be independently constructed, deployed and used. The system combines  the characteristics of group dispatching and command of preset grouping,  and the advantages of high quality voice communication of 4G public network. At the same time, private network 4G can provide exclusive wireless transmission channel,providing  multimedia information distribution and scheduling such as voice, video and image a developed by the terminal based on Android system. Besides, the function of 4G terminal GPS / Beidou can be utilized to provide a map-based object selection and scheduling capabilities, so as to achieve a point-to-point vertical or emergency personnel scheduling. It can be integrated seamlessly with the existing digital cluster and the public security police platform 110 to provide more extensive space and possibilities for daily patrolling and police dispatch in public security departments. It also provides a safer and more reliable protection for mass incidents and major events. 

2. Construct various types of video surveillance and related access, storage, application, and maintenance platform platform and system; build an intelligent operation and maintenance management platform that fully guarantees the status and performance of the system; build a social video access platform to include more extensive social video resources into the security system; build “village to village” video surveillance platform extended to rural areas; build an intelligent combat platform for video images and provide more efficient and effective video applications for video retrieval, comparison and prediction and early warning, to achieve strong police in science and technology, to enhance the combat effectiveness of public security police personnel, and to reduce the pressure on public security officials; Strengthen the video detection management of key personnel, including the dynamic portrait access system and person-in-one comparison.

3. Construct the cloud platform of public security, information and data for public order  prevention and control are sorted out and regulated. According to the requirements of grid management, public order information of key units, key places, public security hot spots and difficult spots is preferentially collected, laying the foundation for grid-based management.

4. Build three-dimensional Geographic Information System (GIS), giving priority to the three-dimensional modeling of key sites and important facilities, and bring all kinds of spatial positioning information into the three-dimensional geographic information system management and application collected by security cloud platform.
