Cl. 178 -6 1 Claim ABSTRACT OF THE DISCLOSURE A video and audio security system for a house under control of an occupant thereof. The system includes a video scanning device at the entrance door of the house to scan a visitor outside the door, and includes audio intercommunication equipment inside and outside the door for conversing with the vistor outside the door. A lock is provided for the door with releasing means for the lock manually controlled by the occupant of the house.

‘ This invention relates to a home security system, and more particularly concerns a system including apparatus mounted at an entrance door of a house, and other cooperating apparatus located remotely in a room of the house.

According to the invention a video scanning device is mounted on an entrance door of a house or apartment to scan a vistor standing at the door. A video picture is transmitted by wireless to a video receiver located in a bedroom or other room of the apartment or house so that an occupant of the house can see who is at the door. The apparatus includes audio intercommunication equipment so that the house occupant can converse with the visitor if desired. The door is equipped with a radio controlled lock which can be actuated by the house occupant to unbolt the dor if entry of the visitor is desired. Audio recording means are provided for recording the conversation with the visitor standing at the door. A radio controlled alarm may also be provided for alerting a guard, policeman or watchman at a security station. The alarm will be actuated by and under the control of the house occupant. The security station may be equipped with video and audio receiving equipment to monitor the video and audio signals passing betwen the apparatus at the entrance door and the house occupant. The monitoring of these signals will occur under control of the house occupant. The video scanning device at the door can be stationary with an optical arrangement for scanning the field of view at the entrance door. Alternatively, the scanning device can be movable under control of the house occupant -for varying the scanned field of view. It is therefore a principal object of the invention to provide a security system for a house, under control of an occupant thereof.

A further object is to provide an entrance door of a house with video equipment for scanning a visitor at the door, and with audio intercommunication equipment at the door so that an occupant of the house can converse with a visitor at the door.

A further object is to provide a security system for a house, the system having devices operable by an occupant of the house, such as devices including an alarm to alert a guard at a security station, video and audio receiving equipment for monitoring video and audio signals, audio recording apparatus, a solenoid controlled safety lock at the entrance door, motor means for moving a scanning device at the entrance door, etc.

For further comprehension and of the objects and advantages thereof, reference may be had to the following description and accompanying drawings and to the ap- 3,482,037 Patented Dec. 2, 1969 pended claim in which the various novel features of the invention are more particularly set forth.

Claims

What is claimed is:

1. A security system for protecting the interior of a place of residence having an entrance door, comprising a plurality of windows in the door disposed in vertically spaced array; protective plates covering the windows, respectively; means pivotally supporting said plates on the door to clear each of the windows; a cabinet containing avideo scanning device; gear means movably supporting the cabinet to move in a vertical path at the door; motor means in the cabinet engaged with said gear means to drive the video scanning device in said vertical path past the windows while the cabinet pivots each protective plate in turn to clear its associated window for exposing said video scanning device at the cleared Window; a video signal transmitter in said cabinet connected to said video scanning device to send a picture of a scanned field in front of each cleared window in turn to a remote location in the interior of said place of residence; radio receiver means in said cabinet; radio transmitter means at said remote location for sending radio signals to said radio receiver; power supply means connected to said motor means for energizing the same to drive the video scanning device up and down; and switch means connected in circuit with said power supply and said radio receiver means for turning on the motor means selectively in response to receipt of a signal from said radio transmitter means, whereby the field in front of each cleared window is scanned in turn.
