[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a television door phone device for confirming the appearance of each outdoor visitor from indoors by using a plurality of camera-equipped entrance slaves.
[0002]
[Prior art]
FIG. 4 shows a schematic configuration of a television door phone device described in Japanese Patent Application No. 8-354474 filed earlier by the applicant of the present application. In FIG. 4, reference numerals 1 and 2 denote camera-equipped entrance slave units, which are connected to the monitor-equipped indoor master unit 3 by two lines. Reference numeral 4 denotes a normal camera-less entrance cordless handset. The camera-less entrance cordless handset 4 is connected to a terminal different from the terminal to which the camera-equipped entrance cordless handset 2 is connected. The indoor base unit 3 with a monitor includes a call circuit, a video demodulation circuit, a CRT, a power supply circuit, an incoming call detection circuit, an incoming ringing circuit, a camera power supply circuit, a data transmission / reception circuit, an FMAGC circuit, and a control circuit for controlling them. Has been. 5 and 6 are indoor cordless handsets with a monitor.
[0003]
Next, the operation of the above apparatus will be described. In FIG. 4, when one of the call buttons of the entrance slave unit with camera 1 or 2 with no camera is pressed by the visitor, the incoming call detection circuit of the indoor master unit 3 with monitor is input via the two lines. Then, the control circuit is activated, sends a ringtone (ping-pong) to the incoming ringing circuit, and in the case of the entrance cordless device 1 or 2 with the camera, the camera feeding circuit is activated, and the entrance cord with the camera 1 2 is fed. The control circuit supplies power to the CRT, whereby the CRT is activated, receives the modulation signal transmitted from the camera-equipped entrance units 1 and 2 by the video demodulation circuit, and displays the demodulated video signal on the CRT. The modulated signal is output to the indoor units 5 and 6 with a monitor through the FMAGC circuit. Furthermore, the indoor slave units with monitors 5 and 6 connected via the data transmission / reception circuit are notified by data of which entrance slave unit is incoming. After that, if you pick up the handset, you can talk to the camera-equipped cordless handsets 1 and 2 through the call circuit.
[0004]
In this way, the above-described TV door phone apparatus can also display a visitor's video by receiving an incoming call, sound a ringing tone, and activate the connected indoor slave units 5 and 6 with a monitor.
[0005]
[Problems to be solved by the invention]
However, the conventional TV door phone device including the above-described TV door phone device could not be connected to any other than the handset with the camera or the handset without the camera as the doorphone slave. The problem to be solved by the present invention is to further expand the functions of the TV door phone device, and its first purpose is to use the surveillance camera and sensor to display the video of the surveillance camera when someone approaches. The second purpose is to use the surveillance camera and the cameraless entrance cordless handset to push the call switch of the entrance cordless handset to the TV doorphone. The third purpose is to make a two-way call with a camera-less entrance cordless handset while checking with the camera. It is to be able to monitor and monitor the video of the surveillance camera.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the television door phone device of the present invention selects an entrance cordless device with a camera, an entrance cordless device without a camera, a monitoring camera with or without a microphone, and a sensor for detecting the situation before the entrance. When the indoor base unit is connected, the entrance unit with camera that can be connected when selecting the entrance unit with camera or the surveillance camera and the entrance unit without camera or sensor are selected. Connectable camera-less entrance cordless handset connection means, camera-less entrance cordless handset connection means for judging whether the entrance cordless handset connected to the cameraless entrance cordless handset connection means is a camera-less entrance cordless handset or a sensor, and no camera A communication path switching means for switching the communication path between the camera-less entrance terminal connection means side or the camera-equipped entrance slave connection means side according to the determination result of the entrance terminal connection determination means. When a cameraless entrance cordless handset is connected to the cameraless entrance cordless handset connection means, the communication path is switched to the cameraless entrance cordless handset connecting means side, and a sensor is connected to the cameraless entrance cordless handset connecting means side Is to switch the communication path to the entrance device connection means side with a camera. Accordingly, the television door phone device can be used as various monitoring systems, and the functions thereof can be expanded. For example, a suspicious person who cannot be found with a normal television door phone device can be found.
