Video and audio security system
First Claim
1. A video and audio security system for monitoring an area, passage beyond which is controlled by a remotely actuable device, the system comprising:
- (1) a video and audio assembly including a video camera, a first speaker and a first microphone, said assembly being disposed to monitor said area and including means for mounting said assembly to a structure such as a door, a wall and the like near said area, said structure having an exterior side and an interior side, said means for mounting including (i) a first plate-like element having an interior and an exterior side, the interior side of said first plate-like element facing said structure when mounted thereto, said first microphone and said first speaker being mounted on the interior side of said first plate-like element, said first plate-like element further including means therein adjacent said first microphone and first speaker to permit sound to pass through said element, and a first light-transmitting aperture, and (ii) a second element adapted to be mounted to a side of said structure opposite the side to which said first plate-like element is mounted, said second element having an interior side facing said structure when mounted thereto and including a second light-transmitting aperture, (iii) a sleeve means extending through said structure between said first and second apertures when said assembly is mounted for use, said video camera being mounted to said second element and having a lens extending through said aperture into said sleeve; and
(iv) fixing means for attaching said first plate-like element and said second element to said structure, said system further comprising(2) a video and audio console spaced from said video and audio assembly, said console including a video display coupled with said video camera to display images received therefrom, a second speaker coupled with said first microphone, a second microphone coupled with said first speaker, and an actuating means operatively coupled with said remotely actuable device;
(3) electric circuitry means including electric circuits coupled with said first and second microphones and said first and second speakers to provide independent two-way sound transmission between said area and said console; and
(4) means for coupling said console to a source of power for supplying power to said console and said assembly.

Abstract
A video and audio system for monitoring an area, particularly an area adjacent a door, is disclosed. The system includes a video and audio assembly adapted to be mounted to a door and a video and audio console spaced from the door. Opening of the door is controlled by an electric door strike operated from the console. The assembly is quite compact which facilitates mounting of the assembly to the door. The video camera includes a right angle optical system which contributes to the compactness of the assembly. Both the console and the assembly include audio elements which permit simultaneous two-way communication. A limited number of conductors none of which carry high voltage couple the assembly and the console.

10. A video and audio assembly for a video and audio monitoring system adapted to be mounted to a structure such as a door, comprising:
-
a first plate-like element adapted to be mounted to one side of the structure and having an exterior side and an interior side, the interior side facing the structure when the first plate-like element is mounted thereto, a first speaker mounted to the interior side of the first plate-like element which adjacent the first speaker is structured to permit sound to be transmitted from the first speaker through the first plate-like element to the exterior side thereof, a first microphone mounted to the interior side of the first plate-like element which adjacent the first microphone is structured to permit sound to pass from the exterior side of the first plate-like element therethrough to the first microphone, the first plate-like element having a first light-transmitting aperture; a second element adapted to be mounted to another, opposite side of the structure and having an interior side facing the structure when the second element is mounted thereto, the second element having a second light-transmitting aperture; a sleeve adapted to extend through the mounting structure between the first and second apertures when the video camera is mounted to the second element and when the second element is mounted to the structure, and having a lens extending through the second aperture into the sleeve; and means for attaching the first plate-like element and the second element to the structure. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
