When the intercom base unit 2 is not connected, the terminal resistor SW is connected to the terminal of the signal line L1 by operating the terminal switch SW4 provided near the input terminal 3d.

  Next, the operation of each unit will be described. First, the control unit 3a receives image data and call voice data captured by the camera 1a and the sensor camera 5 and transmitted from the doorphone slave unit 1 to the interphone master unit 2 via the input terminal unit 3d and the reception unit 3f. The data received from the device 2 and compressed in the compression method used in the Internet network NT (for example, MPEG4 for moving images, JPEG for still images, MP3 for audio, etc.) and stored in the memory unit 3i To do. The image data and call voice data stored in the memory unit 3i are transmitted from the LAN connector 3b through the LAN interface unit 3c and transferred to the center device 7 through the router 6 and the Internet network NT (transfer function). .

  The center device 7 is composed of a general-purpose computer device having a network function, and has a function of storing and relaying each data transmitted through the Internet network NT.

  The mobile terminal 8 is a mobile terminal device such as a notebook personal computer, a mobile phone, or a PDA (Personal Digital Assistance), and performs data communication with the center device 7 via the Internet network NT. Thus, the image data and call voice data stored in the center device 7 can be reproduced by the portable terminal 8 and the visitor confirmation, monitoring, etc. can be performed when the user is away from home. However, since the center device 7 and the portable terminal 8 having the Internet connection function as described above are well known in the art, illustration and description of the detailed configuration are omitted.

  Next, an example of the operation when the image captured by the camera 1a of the doorphone slave unit 1 is accumulated in the center device 7 and the accumulated image is reproduced on the portable terminal 8 will be described with reference to the sequence diagram of FIG. To do.

  First, when an answering machine is set in the interphone master unit 2 (1), an answering setting notification is transmitted from the interphone master unit 2 to the recording transfer controller 3 (2), and the recording transfer controller 3 is also set up (3). ).

  When the visitor presses the call button of the doorphone slave unit 1, the sound / image transmission function of the doorphone slave unit 1 is activated, and the image (image data) and microphone captured by the camera 1 a of the doorphone slave unit 1 are activated. The call voice (call voice data) collected in step (b) is transmitted to the intercom base unit 2. The interphone master unit 2 records the image data and call voice data transmitted from the doorphone slave unit 1 in the semiconductor memory (4), and transmits a visitor notification to the recording / transfer controller 3 (5).

  The recording / transfer controller 3 that has received the visitor notification transmits a visitor event notification to the center device 7 through the router 6 and the Internet network NT (6), and starts recording / recording of image data and call voice data (7). In the video recording / transfer controller 3, the image data and call voice data transmitted from the interphone master unit 2 following the visitor notification are compressed by the control unit 3a using the compression method used in the Internet network NT and stored in the memory unit 3i. Store (8). When the image transfer notification is transmitted from the intercom base unit 2 (9), the recording / transfer controller 3 ends the recording / recording (10), and the image data and call voice data files stored in the memory unit 3i are transferred to the router. 6. Transfer to the center device 7 through the Internet network NT (11), and the center device 7 stores the received image data and call voice data in a recording medium. When the transfer ends, a file transfer completion event is transmitted from the recording transfer controller 3 to the center device 7 (12).

  As described above, since the image data and the call voice data are temporarily stored in the memory unit 3i, even when the communication speed between the recording / transfer controller 3 and the center device 7 is low, the data can be transferred satisfactorily.

  Further, after receiving the visitor event notification from the video recording / transfer controller 3 (6), the center device 7 transmits a visitor notification email to the email address of the pre-registered mobile terminal 8 to notify the resident who is out. If the householder who has received the visitor notification mail wishes to confirm the visitor, the portable terminal 8 may send a browsing request for image / audio reproduction to the center device 7 (14). Upon receiving the browsing request, the center device 7 processes (converts) the image data and call voice data stored in the recording medium into a file format that can be played back by the portable terminal 8, and the processed image data and call voice data are transferred to the portable terminal. (15). As a result, the housekeeper who is out can check the visitor by reproducing the image and the sound on the portable terminal 8 (16).

  As described above, the housekeeper who is out can receive the visitor notification mail from the center device 7, thereby confirming the visitor at the time of absence from the destination, and the timing for requesting the center device 7 to transfer the data to the portable terminal 8. Recognize.

  In addition, when the sensor camera 5 installed in the garden or the like detects the presence of a person in the detection area, image data captured by the sensor camera 5 is transmitted by transmitting an intruder notification from the intercom base unit 2 to the recording transfer controller 3. Is transferred from the recording transfer controller 3 to the center device 7 as described above. Then, a housekeeper who has gone out receiving the intruder notification mail instead of the visitor notification mail can check the intruder by reproducing the image transferred from the center device 7 on the portable terminal 8 as described above. .

  Next, referring to the sequence diagram of FIG. 5, the operation when the image captured by the camera 1 a and the sensor camera 5 of the intercom slave unit 1 is reproduced on the portable terminal 8 by using the image monitor function of the interphone master unit 2 will be described. I will explain.

  This intercom system includes two cameras, a camera 1a of the doorphone slave unit 1 and a sensor camera 5, and a householder who is out can select a camera for reproducing an image. First, when a camera list information request is transmitted from the portable terminal 8 to the center device 7 (1), the center device 7 transmits a camera name acquisition request to the recording / transfer controller 3 (2). In the recording / transfer controller 3 that has received this image monitor request, the camera names registered in advance with respect to the camera 1a and the sensor camera 5 (for example, “location” where the camera is installed, “garden”, etc.) The file is transmitted to the center device 7 as a camera name notification (3). The center device 7 processes (converts) the received camera name notification into a file format that can be played back by the mobile terminal 8, and transmits the processed camera list information to the mobile terminal 8 (4).

  The housekeeper who has gone out displays the camera list information on the portable terminal 8 and selects one of the camera 1a and the sensor camera 5 of the doorphone slave unit 1 to be reproduced (hereinafter, the sensor camera 5 is selected). The camera image request is transmitted to the center device 7 (5), and the center device 7 further transmits the camera image request to the recording / transfer controller 3 (6).

  Upon receiving the camera video request, the recording / transfer controller 3 transmits a camera video request response to the center device 7 (7), and sends a slave unit activation request for enabling the image transmission function of the sensor camera 5 to the interphone master unit 2. (8). The interphone master device 2 that has received the child device activation request activates the image transmission function of the sensor camera 5 and activates the sensor camera 5 (9), and then transmits a child device activation notification to the recording transfer controller 3 ( 10).

  The video recording / transfer controller 3 that has received the slave unit activation notification starts recording the image data (11). In the video recording / transfer controller 3, the control unit 3a transmits the image data transmitted from the interphone master unit 2 to the Internet network. It compresses by the compression system used by NT, and stores in the memory part 3i (12). Then, when the recording time reaches a predetermined time, the recording transfer controller 3 ends the recording (13) and transmits an end request to the intercom master unit 2 (14).

  Receiving the end request, the intercom master unit 2 disables the image transmission function of the sensor camera 5 and stops the sensor camera 5, and then transmits an end completion to the recording transfer controller 3 (15).

  Upon receipt of the completion of completion, the recording / transfer controller 3 transfers the image data file stored in the memory unit 3i to the center device 7 through the router 6 and the Internet network NT (16), and the center device 7 receives the received image data and call. Audio data is stored in a recording medium. At the end of the transfer, a file transfer completion event is transmitted from the recording transfer controller 3 to the center device 7 (17).

  Receiving the file transfer completion event, the center device 7 processes (converts) the image data stored in the recording medium into a file format that can be played back by the mobile terminal 8, and transfers the processed image data to the mobile terminal 8 (18). ). As a result, the housekeeper who is out can reproduce the image on the portable terminal 8 and check the image of the sensor camera 5 (19).

  In this way, by simply adding the recording transfer controller 3 to the interphone system that does not have a recording transfer function built-in, it is possible to check and monitor a visitor when you are away from home. Since there is no need to purchase a new interphone master unit, the recording transfer function can be realized at low cost.

  In addition, a user who does not need the recording transfer function can use the small interphone master unit 2 that does not have a recording transfer function built in in advance, and can construct an interphone system at low cost.

  In this embodiment, the number of cameras is two (camera 1a, sensor camera 5). However, the number is not limited to two. If the recording / transfer controller 3 is used in an interphone system including one or more cameras. The same effects as described above can be obtained.
