Abstract

One embodiment of the present invention is a door viewer comprising a light sensing means coupled to an exterior side of a door, an image system for receiving and processing the signals from the light sensing means, and a display mechanically coupled to the interior side of the door and in communication with the image processing system such that image signals from the image system may be viewed on the display.

In another embodiment, the door viewer is coupled to a motion detecting device such that when an outsider approaches the door, a digital camera records and stores an image of the person. The resident can later determine who approached the door by reviewing the stored images from a display coupled to the interior side of a door.

Claims

1. A door viewer, comprising:

an image sensor adapted for receiving video input signals from a first side of a door and converting the video input signals into output signals,

a processing circuit in communication with the image sensor, wherein the processing circuit is adapted for processing the output signals into processed signals,

a memory device in communication with the processing circuit, wherein the memory device is adapted for storing the processed signals

a display in communication with the processing circuit, wherein the display is adapted to be viewable from a second side of the door, and

an actuating device in communication with the processing circuit, such that upon activating the actuating device, the processed signals are displayed in the form of an image on the display,

a triggering mechanism in communication with the processing circuit such that when the triggering mechanism is triggered, the processed signals are stored in the memory device,

a timer circuit in communication with the processing circuit to measure an interval between triggering events, such that storing of the processed signals is prevented if the interval is less than a predetermined value,

a user interface in communication with the image processing circuit, wherein the user interface is adapted to allow the input of user selectable preferences,

an amplifying circuit coupled to the processing circuit,

a first microphone positioned to receive audible signals from the first side of the door, wherein the first microphone is in communication with the amplifying circuit,

a first speaker in communication with the amplifying circuit and positioned on the second side of the door,

a second microphone positioned to receive audible signals from the second side of the door, wherein the second speaker is in communication with the audio processing circuit, and

a second speaker in communication with the amplifying circuit and positioned on the first side of the door.

2. The door viewer of claim 1 wherein the triggering mechanism is selected from the group consisting of:

a motion detector, circuitry adapted for determining motion coupled to the processing circuit, a radio receiver, and a user interface.

3. The door viewer of claim 1 further comprising a clock circuit in communication with the image processing circuit to determine the time and date of the triggering of the triggering mechanism.

4. The door viewer of claim 1 further comprising:

a memory device,

an audio processing circuit in communication with the first microphone and the memory device, wherein the audio processing circuit is adapted for processing output signals from the microphone such that the processed signals may be stored in the memory device.

5. The door viewer of claim 1 further comprising a radio transmitter in communication with the processing circuit, wherein the radio transmitter is adapted to transmit the processed signals to a radio receiver which is coupled to a network access point.

6. A door, comprising

a planar main body adapted to be hinged in a door frame,

a digital camera adapted to be coupled to the main body such that the digital camera receives at least one image from a first side of the main body,

a control circuit in electronic communication with the digital camera, wherein the control circuit is adapted for processing signals from the digital camera,

a display in communication with the control circuit,

an enclosure for housing the display and control circuit, the enclosure adapted for coupling to a second side of the door such that the display is viewable from the second side of the main body, and

an actuating device in communication with the control circuit, such that upon activating the actuating device, signals from the digital camera are processed by the processing circuit and displayed on the display.

7. The door of claim 6 further comprising:

a memory device in communication with the control circuit, wherein the memory device is adapted for storing the processed signals.

a triggering mechanism in communication with the control circuit such that when the triggering mechanism is triggered, the processed signals are stored in the memory device.

8. The door of claim 7 wherein the triggering mechanism is selected from the group consisting of:

a motion detector, circuitry adapted for determining motion coupled to the processing circuit, a radio receiver adapted to receive signals from a doorbell unit, a radio receiver adapted to receive signals from a motion detection device, and a user interface.

9. A method of identifying a visitor positioned at a first side of a door, the method comprising:
