In this paper, the embedded of remote video monitor system based on S3C2440 of core hardware platform has been successfully developed, and the key technologies have been researched and discussed. Firstly, the overall hardware and software system design are given; vivi has been modified and transplanted for the hardware. The transplantation of the compiler and production of Linux kernel, file system of Yaffs2 also be studied in detail. It is focused on gathering video data used Video4Linux API function and Webcam-Server works
