AN information server has been developed to work as the kernel of remote monitoring system. Web, mail, and database facilities are integrated in the server function. The picture information is obtained from the network camera, accumulated in the server, and distributed to its clients according to their requests. In addition to the remote monitoring function, our server can provide a service for household appliance control. As a GUI client, we have utilized some kinds of cellular phones, and CLDC-based Java programming has been employed to realize the function of clients. For the sake of enhancement of our monitoring function, change from an acquisition picture to another can be analyzed through simple image processing. A service of urgent connection between clients and server is also adopted based on the result of image processing. We introduce an outline of our monitoring system and the contents of its various services, and then explain the detail of Java application which operates on our client devices such as mobile phones.
