CentOS系统管理，系统管理当中的常用命令及其说明文档。(The CentOS Project is a community-driven free software effort focused on delivering a robust open source ecosystem. For users, we offer a consistent manageable platform that suits a wide variety of deployments. For open source communities, we offer a solid, predictable base to build upon, along with extensive resources to build, test, release, and maintain their code.)

说明：  本设计是将安卓技术、单片机技术、无线通信技术等相关技术应用到视频监控系统中，可实现视频监控系统的设备移动化，由可移动监控平台、控制软件两部分组成。通过无线网络对监控平台进行移动方向、速度的控制，平台上的安卓手机摄像头实时采集视频图像信号并通过无线WiFi网络将视频信号实时传输到手机端观看。具有控制方便，监控灵活，模块化，可拓展性强等优点，可应用于险情探测、防爆、现场巡视、家庭安防、图像采集等领域。此部分是安卓端代码。(This design applies Android technology, microcontroller technology, wireless communication technology and other related technologies to the video surveillance system, which can realize the equipment mobility of the video surveillance system. It consists of mobile monitoring platform and control software. The mobile direction and speed of the monitoring platform are controlled by wireless network. The Android mobile camera on the platform collects video image signals in real time and transmits them to the mobile terminal for viewing through wireless WiFi network. It has the advantages of convenient control, flexible monitoring, modularization and expansibility. It can be used in danger detection, explosion-proof, on-site inspection, family security, image acquisition and other fields.)
