Abstract According to the development of industry, conventional surveillance system has not already satisfied by the demand today. The combination application of the CCD camera and image analysis technology in personal computer could enhance the functionality and more and more get a lot of attraction on it. Therefore, CCD camera is gradually popular in people live and industry application. However, CCD camera depends on the process ability of personal computer very much. Furthermore, it can¡¦t work well independently on the application. Based on these problems, this paper proposes an effective monitoring technique to establish an image servo module through using the embedding Ethernet controller with CMOS image sensor. The ¡§image servo module¡¨ can execute independently the designate image monitor work. Eventually, an ¡§Internet-based remote visual monitoring system¡¨ was built by integrating ¡§image servo module¡¨ and ¡§database service system¡¨ to widely promote the application on surveillance system. From the experiment system, user can use the IE explore or Netscape to supervise the internet-based image monitor system from web-server. In addition, a real-time monitor system based on VB program tool was also developed for any computer to monitor or setup the remote image server module to achieve the designated work. The transfer speed of Internet image server system is 7~8 frames/s. Keywords¡Gimage servo module, Internet-based remote visual monitoring systems
