Abstract

A method allowing the audio and video signals of an intercom system to be extended to a mobile communication device via Internet is provided. A server device functions as a relay between a residence-end device of the intercom system and a mobile communication device. The server device is able to forward the audio and video signals from the residence-end device to the mobile communication device through the Internet. Correspondingly, the voice, video, and control signals from the mobile communication device are passed to the server device which in turn feeds the signals to the voice, video, and control circuits of the residence-end device.

Claims

1. A method of integrating an intercom system and a mobile communication device, said intercom system having a residence-end device and a visitor-end device with an appropriate cabling therebetween, said intercom system providing two-way audio communications and at least one-way video communications from said visitor-end device to said residence-end device, said mobile communication device having an audio interface, a video interface, and a mobile data function, comprising the steps of:

providing a server device having a first link to said residence-end device and a second link to Internet, said server device having a network identity;

connecting said mobile communication device to Internet by specifying said network identity and obtaining a network address for said mobile communication device; and

registering said network address in said server device via Internet and said second link;

connecting said server device to said mobile communication device based on said network address in response to said server device'"'"'s receiving a ring signal from said visitor-end device via said residence-end device and said first link; and

converting and forwarding a first audio signal and a first video signal from said visitor-end device via said first link and said server device to said mobile communication device;

converting and forwarding at least a second audio signal from said mobile communication device to said server device;

presenting said fist audio and video signals on said mobile communication device;

presenting said second audio signal on said visitor-end device via said residence-end device and said first link.

2. The method according to claim 1, wherein said first link comprises an audio link connected to a speaker and a microphone of said residence-end device;

a video input link connected to a display of said residence-end device; and

a ringing link connected to a ringing circuit of said residence-end device.

3. The method according to claim 2, wherein said first link further comprises a control link connected to a control button of said residence-end device for opening a gate of said intercom system;

and said method further comprising the step of;

converting and forwarding a control signal produced by a key combination of said mobile communication device to said server device and said residence device via said control link.

4. The method according to claim 2, wherein said mobile communication device comprises a camera;

said first link further comprises a video output link connected to a camera of said residence-end device;

said visitor-end device comprises a display connected to said camera; and

said method further comprising the step of;

converting and forwarding a second video signal obtained from said camera of said mobile communication device to said server device and said residence device via said video output link; and

presenting said second video signal on said display of said visitor-end device.

5. The method according to claim 1, wherein said step of registering said network address further comprises the step of:

authenticating said mobile communication device by requesting a password through an interface before registering said network address.

6. The method according to claim 1, wherein said step of registering said second network address is automatically carried out by said mobile communication device.

7. The method according to claim 5, wherein said password is automatically provided by said mobile communication device.

8. The method according to claim 1, wherein, in response to said server device'"'"'s receiving said ring signal from said visitor-end device, said server device records relevant information about said trigger for later review.

9. The method according to claim 1, wherein, in response to said server device'"'"'s receiving a ring signal from said visitor-end device, said server notifies a party with a short message or an email.

10. The method according to claim 1, wherein said first audio signal, said first video signal, and said second audio signal are synchronously recorded by said server device.

11. The method according to claim 4, wherein said first audio signal, said first video signal, said second audio signal, and said second video signal are synchronously recorded by said server device.
