Design Of Lightweight Network Camera And Implementation Of Monitoring System

In recent years,with the increasing improvement of living standards,the people’s demand for safety has also increased.Video surveillance is an important part of social security maintenance,and it is the most accessible monitoring method for the people in their lives.In some small and medium-sized enterprises and institutions or small and medium-sized surveillance scenes such as daily life,they are more sensitive to cost control and are not suitable for purchasing large-scale video surveillance equipment.In addition,due to the current popularity of smart phones,a video surveillance system implemented through user APP has become an urgent demand.Therefore,this article takes the needs of small and medium-sized surveillance scenarios as the background,in order to meet the needs of office surveillance,home surveillance,and kindergarten surveillance,combined with the technology and industry status of domestic and foreign video surveillance systems,according to the most widely used video codec and streaming media.Transmission technology,proposed a lightweight network camera design and monitoring system solution.The main research contents of this article are as follows:(1)First,analyze the open source code of Easy Darwin,modify part of the interface and data structure according to the needs of this article,to adapt to the signaling transmission;design the execution sequence flow of the signaling to realize the data interaction between the camera and the monitoring program;implement the Easy Darwin-based Streaming media forwarding service program to ensure efficient forwarding of streaming media.(2)Second,complete the integration of Easy Camera on the MSTAR-AIT8328 platform to realize the signaling interaction between the camera and the server;based on the push mode of Live555,the design realizes a lightweight,high-resolution,multifunctional,easy-to-install,The easy-to-configure camera product supports H264 video encoding format,G711,AAC and other audio encoding formats to realize the collection and encoding and decoding of video and audio signals.(3)Again,from the perspective of user privacy protection,this thesis studies and analyzes various encryption algorithms,and in conjunction with the characteristics of RTP packets,designs and implements the use of AES encryption algorithm to encrypt H264 data packets,which can ensure the safety of data transmission.,Improve user privacy protection.(4)Finally,based on the BANDOTT platform,an APP video surveillance system on Android smartphones is designed and implemented,and users can directly watch and manage camera devices.Through the above-mentioned methods for research and development and deployment,the research and development of a practical and lightweight video surveillance system in small and medium-sized surveillance scenarios has been completed.
