Roke Manor Research wants to use the Internet to turn your door bell into an
answering service (GB 2354394). When someone comes to the door while you’re out,
a loudspeaker tells your visitor that they can leave a message while a video
camera records them. A personal computer or WAP cellphone downloads the video
message to your homepage. You pick up your message by tapping in a password and
logging onto your homepage. Should you be online at the time of a call, you can
even talk back to the caller in real time.
