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.
