System overall scheme design 1. Basic description of the project The system design is based on 4G wireless transmission video surveillance system. The portable 4G image transmission equipment is fired with the fire truck. After reaching the scene, it is quickly set up on site, and 4G is used to transmit video signals without laying network cables. Greatly reduce the construction cost, and at the same time, it can easily realize remote video monitoring anytime and anywhere. The video data can be recorded at any time for easy retrieval and review. In addition, law enforcement officers wear 4G individual image transmission equipment, record and record live scenes at close range, and the command center can directly direct to the individual through two-way voice. The system design fully considers the system scalability. When the system is expanded, only 4G equipment needs to be added, which does not affect the normal operation of the system, and can realize the convenient expansion of the system. Compared with traditional video surveillance has an irreplaceable advantage.

The 4G individual image transmission equipment is worn by law enforcement officers in front, and the small size does not affect the action.
The front-end video surveillance device uploads the video images of each monitoring point captured by the camera and compresses them to the monitoring center through 4G to realize remote viewing of the video. At the same time, according to the commands issued by the operation of the monitoring center, it can control video switching, lens zoom, close-range/distant view, aperture adjustment, etc., as well as controlling the up, down, left and right, and automatic patrols of the pan/tilt. The specific design is:
(1) The armed police fire truck adopts portable 4G image transmission equipment and PTZ cameras, and law enforcement personnel wear 4G individual image transmission equipment to complete the layout of all monitoring stations;
(2) The power of the front-end equipment is provided by the battery, and the equipment can be turned on at any place.
(3) The front-end device automatically dials up for wireless Internet access and obtains a dynamic public IP address. After the dialing is successful, the encoded image information stream is actively sent to the 4G gateway program through the 4G wireless channel.
(4) The installation location of the 4G gateway program must have a fixed public IP address, or in a local area network with a fixed public IP address, the port can be changed by the user!
(5) The user connects to the 4G gateway program through the monitor software to acquire video or control the camera.
monitoring Center:
In the monitoring center computer room, one server is configured as a central server (wireless video gateway), a storage server, and a monitoring host to realize management, storage, and video browsing of each monitoring point video, and control of the front camera.
(1) Install “Zhongchuang Hexin Server Management Platform Software†on the central server, responsible for the management of the entire system;
(2) The monitoring host installs “Zhongchuang and Xin video surveillance management softwareâ€, which is responsible for the image of the video data of each monitoring point. It can perform operations such as recording, snapping, voice intercom, GPS track monitoring and query, video download and playback. The amount of hard disk space required for recording is determined by the number of video recordings, the length of recording time, the recording save period, image quality, frame rate, and picture complexity. Usually, the video file size of a mobile device for 1 hour is about 800M, and the video file size of a mobile device for 1 hour is about 250M. For example, portable video 10 video recording 3 days, daily video recording 3 hours, required disk Space: 800M/H×3H×3 days×10 roads≈72G;
