Video surveillance system can provide remote video surveillance , convenient and intuitive , and can be widely used in industrial , transportation , finance , teaching and other fields . With the development of computer technology and network technology , the traditional monitoring system will be embedded network video surveillance system alternative, plays an important application in various fields . This article describes an infrared network video surveillance system based on embedded Linux software design , system hardware core ARM9 processor i.mx27 , using the Linux operating system , will be collected from the infrared CCD video image coding , network transmission , decode and display the RMON monitoring site , CCD monitoring the use of infrared light from dark , therefore , such a system can achieve all-weather monitoring . This paper focuses on the Linux embedded the infrared network video surveillance system development , the first to compare a variety of monitoring system hardware , selected hardware , system hardware development board . Then details the construction of a software development platform for Linux system characteristics , completed development board programmed the uboot operation and in order to do the guide transplant kernel , file system , and the brief introduction to the compilation of the driver . Download the. In system software design , this article describes the design process of the video image capture , encoding , transmission , decoding module . And, ultimately, the based embedded Linux infrared network video surveillance system software design .
