中文摘要：

为设计基于ARMCotex-M3内核的视频监控安防系统，采用NXP的LPCI768芯片及USB免驱动摄像头，首先利用USB摄像头采集现场环境的图像，图像数据经由ARM处理器通过以太网传输到用户电脑的上位机软件显示，通过UDP打洞或服务器转发的方法，实现全国范围内的远距离视频监控。实验效果好，视频图像流畅清晰。重点介绍视频监控安防系统的系统设计，硬件构造，及相关软件设计。

英文摘要：

In order to design based on the ARM cotex- M3 core of video surveillance systems,the NXP lpc1768 chips and driver free USB cameras were adopted. First,the USB camera was used to catch the environmental image data,image data was sent by the ARM processor through ethernet to the user~ computer software and displayed on upper computer software, through UDP hole punching or Server forwarding to achieve nationwide distance video surveillance. The experimental result was effectual and the video image was clear and fluency. The video surveillance security system＇s system design,hardware construction,software design process and the methods of related software were mainly introuduced in this paper.
