JPH04133588A - Video monitoring system and video monitoring system for multiple dwelling house - Google Patents

Abstract

PURPOSE:To prevent the transpiration of privacy in a multiple dwelling house by constituting the above system of a transmitting/receiving section which receives data signals set from a central control unit, controlling section which analyzes received data, relay section which is actuated by the controlling section, video inputting section which inputs video signals, and an outputting section which outputs the video signals selected by the relay section. CONSTITUTION:When a visitor depresses a call button 1b after inputting the number of the house the visitor wants to visit by operating ten-key buttons 1a, the data signal of the house number is transmitted to a central controller 2 and, at the same time, the video signal of a TV camera 1c is transmitted to a video switching device 6. At the device 6, a transmitting/receiving section 6d receives data sent from the controller 2 and, when a pertinent house exists, the video signal inputted from a video input terminal 6a is switched at a relay section 6f by means of a relay controlling section 6e. When no pertinent house is found among video output terminals 6b, the video signal is not switched, but outputted to a video output terminal 6c. In the pertinent house, on the other hand, when the resident of the house actuate a monitoring television receiver 4 in response to the ringing sound of the call bell of an interphone 3, the video of the visitor is displayed on the receiver 4.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a video monitor system used in apartment complexes and the like.

(Prior Art) In recent years, video monitoring systems that can monitor visitors at the front door of apartment complexes have become commonplace for the purpose of safety and comfort. This type of conventional video monitor system will be explained with reference to FIG.

This figure is a configuration diagram of a conventional video monitoring system for an apartment complex.A common entrance device 1 installed at the entrance of a multi-story apartment complex has a numeric keypad button la to specify the house to be visited.
It consists of a call button 1b, and a television camera IC that takes a picture of the visitor. The center control device 2 is connected to the above-described communal entrance device 1, an interphone 3 and a monitor television 4 installed in each residence. Further, the above-mentioned common entrance device 1 installed on each floor and the connected video distributor 5 are connected to the monitor television 4 of each house on the installation floor.

The operation of the video monitoring system for an apartment complex configured as described above will be explained.

When the visitor first operates the numeric keypad 1a to input the house number he/she wishes to visit and then presses the call button lb, the data signal of the house number is sent to the center control device 2, and at the same time the television camera The video signal captured by the IC is transmitted to all houses via the video distributor 5. Next, the center control device 2 rings the call bell of the intercom 3 of the residence corresponding to the transmitted data to notify that there is a visitor.

At the residence where the notification has been received, the monitor TV 4 is activated and an image of the visitor at the entrance is displayed.

(Problem to be Solved by the Invention) However, in the above configuration, since the image of the visitor is transmitted to all residences, there is a problem that privacy is leaked.

The present invention solves the above problems and provides a video monitor system that allows video to be viewed only in the relevant residence.

(Means for Solving the Problems) In order to solve the above problems, the present invention replaces the video distributor with a video switching device, and includes a receiving section for data signals sent from the center control device, and the above-mentioned video switching device. A control unit that analyzes received data, a relay unit that is controlled by the control unit, a video input unit that receives input from the center control device, and a video output unit that outputs the video selected by the relay unit to a monitor television. and a video output section for outputting video to another video switching device.

(Operation) With the above configuration, images of visitors can be received only at the corresponding residence.

(Example) An example of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram showing a video switching device of the present invention;
FIG. 2 is a block diagram of a video monitor system according to the present invention. First, the video monitor system according to the present invention will be explained with reference to FIG. This embodiment differs from the conventional example shown in FIG. 3 in that a video switching device 6 is installed in place of the video distributor 5 of the conventional example. Since the rest is the same as the conventional example, the same components are given the same reference numerals and their explanations will be omitted.

Next, the above-mentioned video switching device 6 will be explained with reference to FIG. 1, taking as an example the case where it is installed on the negative floor. The video switching device 6 has a video input terminal 6a connected to a television camera lc (both not shown) of the common entrance device 1, and a video input terminal 6a connected to a television camera lc (both not shown) of the common entrance device 1, and a monitor television 4 of each house divided on the first floor from room 101 to room N.
(not shown), a plurality of video output terminals 6b connected to
A video output terminal 6c connected to a video switching device 6 (not shown) installed on the floor, a transmitting/receiving section 6d connected to the center control device 2 (not shown) and transmitting/receiving data thereto; Relay control unit 6e that analyzes and controls the relay
and a relay section 6f that switches the video signal to each video output terminal 6b.

The operation of the video monitor system for an apartment complex configured as described above will be explained.

The visitor first operates the numeric keypad 1a to input the house number to visit, and then presses the call button 1b.
At the same time that the data signal of the house number is transmitted to the center control device 2, the video signal of the television camera 1c is transmitted to the video switching device 6.

When the center control device 2 receives the above data signal, it notifies the corresponding residence and video switching device 6 that there is a visitor.

In the video switching device 6, the transmitting/receiving section 6d receives the data from the center control device 2, and if there is a corresponding house, the relay control section 6e switches the video signal input from the video input terminal 6a using the relay section 6f. If there is no corresponding house at the video output terminal 6b, the relay is not switched and output is made to the video output terminal 6c. On the other hand, at the relevant residence, the intercom 3's call bell rings, and when the monitor television 4 is activated, an image of the visitor at the entrance is displayed.

As described above, according to this embodiment, since the image is displayed only on the monitor television 4 of the house number input by the visitor, leakage of privacy can be prevented.

(Effects of the Invention) As explained above, according to the present invention, a video monitor system is provided that can prevent leakage of privacy in an apartment complex because the video is displayed only on the monitor TV of a specific residence specified by a visitor.
