Abstract

A surveillance system is provided having a base unit for receiving digital video and audio transmissions from accessory units equipped with a camera having pan and tilt functions, a motion sensor, an intercom, infrared sensors and a doorbell button for contacting the interior of the dwelling a recording feature is provided to both automatically and on demand record video and audio transmissions received by the base unit from the accessory units.

Claims

1. A surveillance apparatus comprising:

at least one base unit, said base unit having a radio frequency transmitter and a radio frequency receiver for transmitting and receiving digital radio frequency audio and video signals, a liquid crystal display for displaying received video signals to a user, a speaker for transmitting received audio signals to said user, a microphone for receiving audio signals from said user, a pan and tilt control for signaling and manipulating a remote video camera, a digital video recorder memory for recording video images received by said base unit from said remote video camera, and

at least one first auxiliary unit having a radio frequency transmitter and a radio frequency receiver for transmitting and receiving digital radio frequency audio and video signals to and from said base unit, a speaker for transmitting received audio signals to a visitor, a microphone for receiving audio signals from said visitor for transmission to said base unit, a remote video camera responsive to said pan and tilt control manipulation signals received from said base unit and for receiving a video image for transmission to said base unit and said first auxiliary unit having switch thereon for permitting said visitor to activate a dwelling door bell.

2. The apparatus as claimed in claim 1 further comprising at least one second auxiliary unit comprising a radio frequency transmitter and radio frequency receiver for transmitting and receiving digital radio frequency audio and video signals to and from said base unit, a speaker for transmitting received audio signals to a visitor, a microphone for receiving audio signals from said visitor for transmission to said base unit, a remote video camera responsive to pan and tilt control manipulation signals received from said base unit and for receiving a video image for transmission to said base unit.

3. The apparatus as claimed in claim 1 further comprising a selector switch on said base unit for user determination of which of said auxiliary units said base unit is to receive and transmit signal between.

4. The apparatus as claimed in claim 1 further comprising a plurality of infra-red lights on said first auxiliary unit for providing illumination for said video camera.

5. The apparatus as claimed in claim 2 further comprising a plurality of infra-red lights on said second auxiliary unit for providing illumination for said video camera.

6. The apparatus as claimed in claim 1 further comprising a motion detector on said first auxiliary unit for sensing movement proximate to said first auxiliary unit and to activate transmission of a video signal from said first auxiliary unit to said base unit.

7. The apparatus as claimed in claim 2 further comprising a motion detector on said second auxiliary unit for sensing movement proximate to said second auxiliary unit and to activate transmission of a video signal from said second auxiliary unit to said base unit.

8. A surveillance apparatus comprising:

at least one base unit, said base unit having a radio frequency transmitter and a radio frequency receiver for transmitting and receiving digital radio frequency audio and video signals, a liquid crystal display for displaying received video signals to a user, a speaker for transmitting received audio signals to said user, a microphone for receiving audio signals from said user, a pan and tilt control for signaling and manipulating a remote video camera, a digital video recorder memory for recording video images received by said base unit from said remote video camera,

at least one first auxiliary unit having a radio frequency transmitter and a radio frequency receiver for transmitting and receiving digital radio frequency audio and video signals to and from said base unit, a speaker for transmitting received audio signals to a visitor, a microphone for receiving audio signals from said visitor for transmission to said base unit, a remote video camera responsive to said pan and tilt control manipulation signals received from said base unit and for receiving a video image for transmission to said base unit and said first auxiliary unit having switch thereon for permitting said visitor to activate a dwelling door bell, and

at least one second auxiliary unit comprising a radio frequency transmitter and radio frequency receiver for transmitting and receiving digital radio frequency audio and video signals to and from said base unit, a speaker for transmitting received audio signals to a visitor, a microphone for receiving audio signals from said visitor for transmission to said base unit, a remote video camera responsive to pan and tilt control manipulation signals received from said base unit and for receiving a video image for transmission to said base unit.

9. The apparatus as claimed in claim 8 further comprising a selector switch on said base unit for user determination of which of said auxiliary units said base unit is to receive and transmit signal between.

10. The apparatus as claimed in claim 8 further comprising a plurality of infra-red lights on each of said first and said second auxiliary units for providing illumination for said video camera.

11. The apparatus as claimed in claim 8 further comprising a motion detector in each of said first and second auxiliary units for sensing movement proximate to said first auxiliary unit and/or said second auxiliary unit and to activate transmission of a video signal from said first auxiliary unit or said second auxiliary unit to said base unit.
