Research Of Remote Video Surveillance System Based On ARM

Video surveillance system is a integrated technology, including computer,communication and digital video technology. At present the video surveillancesystem is developing at digitization and network. An embedded system device is keyto video surveillance based on network. It should be able to gather video data andcarry on data through network.This article introduced a method of network video surveillance system based onLinux. At first, has analyzed a design plan of network surveillance system from thewhole, introduced the hardware and the software system, and discussed emphasislyMPEG-4 encoding on ARM processor. Next constructed armlinux in the ARMhardware platform successly including Bootloader design, configuring linux kernelas well as JFFS2 file system. Starting U-BOOT from nandflash is a new method. Inorder to complete next work, the paper has realized the driver of USB camera. In theapplication programming, has first designed video gathering program based on theVideo4Linux, and uses mmap () to capture. Next has emphasisly analyzed XVIDcode, MPEG-4 module, and optimizing the code of movement estimate part. Finallyuses JRTPLIB to carry video stream.All design is based on SUPER-ARM hardware platform in Shenzhen. Linuxkernel version is 2.4.18. ADS 1.2(ARM Developer Suite) is used testing MPEG-4code. This paper has made the beneficial exploration realize network videosurveillance system based on ARM, and help to further study on remote embeddedvideo surveillance system.
