Abstract

An audio/video intercom system provides transmission of video and audio signals from a remote originating unit to a computer monitor and speaker for display and reproduction. The system includes an access point router coupled to the computer that receives the remotely originated video and audio signals. The access point router provides the remotely originated video and audio signals to the computer to enable display of the video signals on the monitor and reproduction of the audio signals on the computer speaker.

Claims

1. An audio video intercom system comprising:

a computer;

a monitor that displays images from video signals generated by the computer;

a speaker that reproduces sound from audio signals generated by the computer;

a remote camera and microphone unit that generate remotely originated video and audio signals, and

an access point router coupled to the computer that receives the remotely originated video and audio signals and provides the remotely originated video and audio signals to the computer for generation of corresponding video and audio signals to be displayed by the monitor and reproduced by the speaker.

2. The system of claim 1 further comprising a cable modem coupled to the access point router.

3. The system of claim 1 wherein the computer includes a hard drive for logging the video signals.

4. The system of claim 1 wherein the access point router is adapted to transmit audio signals to the remote camera and microphone unit for reproduction of corresponding sound by the microphone.

5. The system of claim 1 wherein the remote camera and microphone unit transmitter is a radio frequency transmitter and wherein the access point router includes a radio frequency receiver.

6. A wireless audio video intercom system comprising:

a computer;

a monitor that displays images from video signals generated by the computer;

a speaker that reproduces sound from audio signals generated by the computer;

a remote camera and microphone unit that generate remotely originated video and audio signals, and including a radio frequency transmitter that transmits the remotely originated video and audio signals; and

an access point router coupled to the computer including a radio frequency receiver that receives the remotely originated video and audio signals and provides the remotely originated video and audio signals to the computer for generation of corresponding video and audio signals to be displayed by the monitor and reproduced by the speaker.

7. A device comprising:

a camera that generates a video signal from an image;

a microphone that generates an audio signal from sensed sound;

a housing enclosing the camera and microphone; and

a transmitter within the housing that transmit the video and audio signals for reception by an access point router and distribution to a computer and monitor.

8. The device of claim 7 wherein the transmitter is a radio frequency transmitter.

9. The device of claim 7 wherein the transmitter is configured to transmit the video and audio signals over an alternating current power line.

10. The device of claim 7 wherein the transmitter is configured to transmit the video and audio signals over an Ethernet line.

11. A method comprising:

producing a video signal;

producing an audio signal;

transmitting the audio and video signals to an access point router; and

displaying the video signal on a computer monitor associated with the access point router.

12. The method of claim 11 comprising the further step of reproducing sound from the audio signal with a speaker associated with the computer.

13. The method of claim 11 comprising the further step of logging the video signal on a hard drive associated with the computer.

14. The method of claim 11 wherein the transmitting step includes transmitting with radio frequency energy.

16. An audio video intercom system comprising:

computer means for generating video signals containing images and audio signals containing sound;

display means for displaying the images from the video signals generated by the computer means;

speaker means for reproducing the sound from the audio signals generated by the computer;

remote unit means for generating remotely originated video and audio signals, and

access point router means for receiving the remotely originated video and audio signals and providing the remotely originated video and audio signals to the computer means for generation of corresponding video and audio signals for display by the display means and reproduction by the speaker means.

15. The method of claim 19 comprising the further step of conveying the video and audio signals from the access point router to a cable modem.

17. The system of claim 16 wherein the computer means includes hard drive means for logging the video signals.

18. The system of claim 16 wherein the access point router means includes means for transmitting audio signals to the remote unit means for reproduction of corresponding.

19. The system of claim 16 wherein the remote unit means includes radio frequency transmitting means for transmitting radio frequency signals and wherein the access point router means includes radio frequency receiving means for receiving the transmitted radio frequency signals.

20. The system of claim 16 wherein the remote unit means includes means for transmitting the remotely originated video and audio signals over an alternating current power line.
