| The wireless video surveillance system is a new type of surveillance system that combine surveillance system with wireless network.The system transmits video data to the surveillance terminal through the wireless network.In recent years,ordinary wireless video surveillance system has been unable to meet the needs of users.They wish to be able to surveil anytime and anywhere.Therefore,many security companies have begun to focus on the realization of wireless video surveillance products available on mobile phones.This paper designs and implements a wireless video surveillance system based on the three-layer structure of the collector /server/client.At the collector,the two technologies of OpenCV and FFmpeg are mainly used in this system,to imply image acquisition and push flow.As to the server,the platform mainly uses lightweight development framework spring-Boot development,the database uses the stable PostgreSQL database.Use Nginx acts as a streaming media distribution server.The server depend on XGPush SDK to imply alarm pushing function.On the client part,the system mainly uses the ijkplayer on the iOS system to receive,decode the stream.This paper completed the system requirements analysis and system use case analysis based on the background of the wireless video surveillance system and mobile application.Then,the system design was completed: the system was divided into the collector,the server,and the client,and the three-terminal structure design was carried out according to the self-blame conversion of each terminal;and the design of the database table related to the main business logic of the system was introduced.Finally,the specific implementation,operation logic and test results of the mobile application are expounded in detail,and the function screenshots of the system are given.After testing,the system implemented in this paper can achieve all the functional requirements,and can achieve the requirements of the wireless video surveillance system. |
