After the message reproduction is completed, the tape recorder 12 switches the mode to the recording mode and records the business, etc., of the visitor.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a door phone device having a function of keeping records of visitors when the door is away.

2. Description of the Related Art Conventional door phone devices have only a ringing function and a function for communicating with a telephone receiver in a house.

Problems to be Solved by the Invention However, the above-mentioned conventional device has the inconvenience that it does not function at all when a visitor arrives while the family member is away.

Means for solving the problem In order to solve the above problem, when the door 2-on button is pressed, a pre-recorded message is sent to the tape recorder, and at the same time, the guest's business is recorded on the tape recorder. In addition to recording, a function is added to input images of visitors from a TV camera (door camera), convert them to still images, and then record them in a still image recording database.

By adding the above-mentioned functions, the present invention makes it possible to record a visitor's business and record a video of a visitor's person when one is away, and after the family member returns home, the family member can play it back on a tape recorder or search a database for still image recording. By playing back the information, it is possible to confirm whether there are any guests, the business of the guests, and the person of the guest.

Example Embodiments of the present invention will be described in detail below with reference to the drawings.

First, in the normal state (at home mode), the call path switching device 6 can make a call between the doorbell outside device 2 and the interphone device 9, and can also communicate with visitors through the television camera 1 and television (monitor) 16. can be monitored.

Next, the operation of this device when the family member is away will be explained. In order to operate this device when the user is away from home, first switch to the away mode using the away switch 8 installed in the door-on control section 7. By switching to the absence mode, the door 7 on control unit 7 controls the call path switching device 6 to connect the door fob/outside device 2 to the tape recorder 12 for playing messages and recording messages, and at the same time stops the television camera 1. It is connected to the image conversion device 13. This operation sets the device to the away mode. Next, when the visitor presses the push-button switch 6 of the door phone device 2 set to the absentee mode, the door 7 on control section 7 is notified of the presence of the visitor. At this time, the door phone control unit 7 sends a message playback request signal to the tape recorder 12 for message playback, and at the same time as starting the message playback, sends a video signal capture signal to the still image conversion device 13 for video signal conversion, and Input the video signal. The still image conversion device 13 converts the input video signal into still image data, transfers it to the database device 14, and records it. Further, after the message reproduction is finished, the tape recorder 12 switches to the recording mode and records the visitor's business matters.

Next, there are two types of means for reproducing still image data and recordings of business matters recorded by the above method, and each will be explained.

The first method is to receive the video from outside the home via a public telephone line on a portable image communication terminal 19, and the second method is to play it back on the television (monitor) 16 after the family member returns home.

First, the first method will be explained.

If a person (operator) is out of the house and wants to know if there are any visitors while he/she is away, what to do if there are any visitors, and who the visitors are,
First, call the house. In this case, since the device is set to the absentee mode, the automatic call receiving device 17 answers the incoming call, connects the modem 20 to the public telephone line 18, and communication between the database device 14 and the outside is established. Make it possible. The operator confirms that the modem 2o is connected to the public telephone line 18 by listening to the carrier sound from the modem 2o, and connects the portable image communication terminal 19 to the public telephone line 1.
Connect with 8. Next, the operator uses the input device of the portable image communication terminal 19 to input the PIN number and connects the public telephone line 1.
8 to the database device 14. The database device 14 determines whether the input password is the same as a preset number, and if the password is correct, the database device 14 transmits the recorded still image data to the portable image communication terminal 19. Forward. The portable image communication terminal 19 receives this still image data and displays it on the display. Further, after transmitting the still image data, the database device 14 controls the tape recorder 12, transfers the recorded business to the public telephone line 18, and receives it at the portable image communication terminal 19. By the above operations, the operator who is out of the house can view the still image of the visitor who is away, and can also listen to the visitor's business recorded on the tape recorder 12.

Next, the second method will be explained.

The second method is when a family member returns home from going out.
By pressing the answering switch 8 of the door phone control unit 7, the call path switching device 6 is controlled to return the call path to the normal state, and at the same time, a control signal for a playback request is first sent to the database device 14. The still image data is transferred from the still image demodulator 14 to the still image demodulator 15, demodulated into a video signal, and then reproduced on a television (monitor) 16. Then, a reproduction request signal is similarly sent to the tape recorder 12 from the door phone control unit 7, and the television (monitor) 1
The recorded audio is played back from the 6 speakers.

As explained above, this device not only keeps records of visitors when you are away, but also allows family members to play back and monitor video and audio signals recorded via public telephone lines after returning home or from outside the home. It functions as a door phone device with an answering machine function.

Effects of the Invention As described above, the present invention expands the functions of the doorbell, thereby making it possible to record and reproduce the history of guests while the householder is away, which was not possible with conventional devices.
