Though typical video door phone systems can be used to talk to the visitors at the door, they have some shortcomings: the resident should stay in house and he/she could not be informed of any visitor information on his/her return to home. To overcome these limitations, we propose an architecture supporting user mobility, with which the resident at anywhere can view and converse with a visitor at the front door using PC’s, PDA’s and home servers with internet connections. We implemented the proposed architecture using SIP(session initiation protocol) and a home gateway system connected to a conventional intercom or a video door phone system.
