Abstract

PURPOSE:To attain the confirmation of a visitor during absence and the recording of a voice message by constituting a monitor equipment such that a video signal from a camera and a voice signal from a microphone are converted into a television signal, the signal is sent in a radio wave, the radio wave is received and selected by a tuner section and recorded on a magnetic tape and monitored by a receiver. CONSTITUTION:When a switch 1 is closed by a visitor, a power supply 2 is supplied to a camera 3, a microphone 4, a television signal transmitter 7, a chime 6 and a sensor input terminal 10c of a VTR 10. A television signal transmitter 7 modulates the inputted video signal and voice signal and converts them into a television signal and the signal radiates in air from a transmission antenna 8 as a radio wave. The radio wave is received by a reception antenna 9 and selected by a tuner of the VTR 10 and recorded on a magnetic tape loaded to the VTR 10 finally. In this case, the receiver 5 receiving the video signal from the video output terminal 10a and the voice signal from the voice output terminal 10b simultaneously identifies and monitors the visitor indoor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a monitoring device used for home use or the like.

[Conventional technology]

FIG. 2 shows the configuration of a conventional monitoring device. In FIG. 2, 1 is a push-button switch installed at the entrance door or gate, 2 is a power source, 3 is a camera for imaging, 4 is a microphone, 5
is a monitor receiver, and 6 is a chime. camera 3
and microphone 4 are installed outdoors near switch 1.

Next, the operation will be explained. When switch 1 is closed by the visitor, power 2 is supplied to the system and cameras 3.
Microphone 4. The receiver 5 becomes operational. Additionally, chime 6 sounds to notify the visitor that there is a visitor. Inside the house, the receiver 5 inputs the video signal output from the camera 3 that images the visitor and the audio signal output from the microphone 4 that converts the visitor's voice. Visitors can be recognized and monitored using the screen and audio in step 5.

[Problem to be solved by the invention]

Conventional surveillance devices are configured as described above, so they are useless if a visitor arrives while you are away, and they are not suitable for monitoring suspicious persons. There were issues such as the need for additional wiring work.

This invention was made to solve the problems mentioned in J.2.1. Even if you are absent, you can check who visited you later and whether they left a message, and you can monitor for a long time. The purpose is to obtain a monitoring device that can

[Means to solve the problem]

The monitoring device of the present invention converts a video signal from a camera and an audio signal from a microphone into a television signal, emits it as a radio wave from a television signal transmitter, receives the radio wave, and selects a channel in a chase section. This allows the video to be recorded over a long period of time using a video recorder and simultaneously monitored using a television receiver.

[Function] The monitoring device according to the present invention transmits video signals and audio signals as radio waves using a television signal transmitter, tunes them using a long-time video tape recorder with a tuner, and records them on a magnetic tape. It can be recorded and monitored using a receiver.

〔Example〕

Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 shows the configuration of a monitoring device according to an embodiment of the present invention.

When the switch 1 is closed by the visitor, the power supply 2 is applied to the camera 36 microphone, the television signal transmitter 7, the chime 6, and the sensor input terminal 10c of the VTRIO, and the video signal from the camera 3 and the microphone 4 are output. The audio signal is supplied to the television signal transmitter 7.

However, when switch 1 is pressed, power supply voltage is applied to the sensor input terminal 10c. , the VTR 10 switches to continuous recording mode, and after a predetermined period of time has elapsed, returns to long-term recording mode again.

With VTRlO, it is currently impossible to record audio in long-term recording mode, but in continuous recording mode, it is possible to record audio without any problems, and it is possible to record messages from visitors when you are absent. Can record.

(Effects of the Invention) As described above, according to the present invention, a video signal from a camera and an audio signal from a microphone are converted into television signals and transmitted by radio waves, and the radio waves are received and a television signal is transmitted. The system was configured so that the department can select a channel and record it on magnetic tape while simultaneously monitoring it on the receiver, so it is possible to check on visitors when they are absent, and even record voice messages. It also has the effect of allowing constant monitoring.Also, since it transmits and receives via radio waves, there is no need for cable wiring work, and since it is a long-time VTR with a built-in part, it can be easily used with a regular VTR. It can also be used for both purposes, making it effective for monitoring in a tea room, etc.
