A Lock Opening and Closing System with the Image Base Using a Cellular Phone through the Internet
Description
Now a day, we use cellular phones to display color images, characters, and to connect to the Internet. As an Internet applications for future generations, we built a system in which electric equipment was connected to a web server and controlled by a cellular phone. More specifically we constructed a system to open and close a door using a cellular phone. One of the most important problems is that nobody knows the condition of a room, if somebody is not present in the room. In order to solve this problem, a pan-tilt camera is set in the room. The web server can control this camera, and the user can select various directions from which the image can be taken. An automatic lock system is built with human detection. Movement and color information is used in aiding human detection. By experimenting with this automatic lock system, the security of this system was confirmed.
