  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram showing an example of an interphone system according to the present invention. 1 is an interphone slave unit (hereinafter simply referred to as a “slave unit”) for selecting and calling a destination, and 2 is a slave unit 1. Interphone master unit (hereinafter simply referred to as “master unit”) for responding to a call from, 3 is a recording device for recording video transmitted from slave unit 1, and includes a plurality of slave units 1 and 2. The devices are connected via a general-purpose communication network 4 such as a LAN.

  The subunit | mobile_unit 1 selects the subunit | mobile_unit 2, the subunit | mobile_unit operation part 11 which performs a call operation, the microphone 12 and speaker 13 for calling, the camera 14 for imaging a visitor, and subunit | mobile_unit CPU15 which controls the subunit | mobile_unit 1 A slave unit communication IF 16 for communicating with the master unit 2 and the like via the general-purpose communication network 4 is provided.

  The base unit 2 displays a base unit operation unit 21 composed of a touch panel for performing various operations such as video display operation, a call button 22 for responding to a call, a microphone 23 and a speaker 24 for making a call, and a video and the like. Display unit 25, a parent CPU 26 that controls the parent device 2, and a parent device communication IF 27 for communicating with the child device 1 and the like via the general-purpose communication network 4.

  The recording device 3 includes a storage unit 31 that stores a password for permitting access to the parent device 2 in addition to recording the captured image of the slave camera 14, a recording device CPU 32 that controls the recording device 3, and a general-purpose communication network 4. And a recording device communication IF 33 for communicating with the child device 1 and the parent device 2 and the like.

The operation of the intercom system configured as described above is as follows. An operator such as a visitor operates the slave unit operation unit 11 of the slave unit 1 to select a call destination master unit 2 and perform a call operation. For example, in the case of an office building, the department to be visited is selected, and when the callee master unit 2 is selected, a call button (not shown) is pressed to select the master unit 2 selected by the control of the slave CPU15. A call signal is transmitted.
The slave CPU 15 activates the camera 14 in response to the call button operation, and transmits the captured image to the master 2 and the recording device 3. At this time, in the video signal transmitted from the slave unit CPU 15 to the master unit 2 and the recording device 3, the slave unit ID information for identifying the source slave unit 1 and the parent unit for identifying the callee master unit 2 are included. Machine ID information is attached and transmitted by multicast.

The base unit 2 that has received the call signal reports a ringing tone from the speaker 24 under the control of the base unit CPU 26, and the received video is displayed on the display unit 25.
When the call button 22 is operated by the responder who recognizes this call, a call path is formed with the handset 1, and the responder makes a call while watching the video of the visitor displayed on the display unit 25. Can be implemented. Thereafter, when a predetermined call termination operation is performed, the communication path is disconnected and the video display is also terminated.

  On the other hand, the recording device 3 that has received the video signal is recorded in the storage unit 31 under the control of the recording device CPU 32. At this time, the slave unit ID information and the master unit ID information attached to the video signal are also stored in the storage unit 31 together. This video recording ends when the transmission of the video signal is received from the slave unit 1, that is, when the end operation of the master unit 2 is received.

The video recorded in the recording device 3 in this way can be browsed / erased by the parent device 2. When a predetermined browsing operation of the parent device operation unit 21 is performed in the standby parent device 2, the parent device CPU 26 transmits a list request signal to the recording device 3.
When the recording device 3 receives the list request signal, the recording device CPU 32 reads the video information associated with the parent device 2 of the signal transmission source from the storage unit 31 based on the parent device ID, and creates a list of the recorded videos. To the base unit 2. The base unit 2 that has received the list information displays the list on the display unit 25.
FIG. 2 is an explanatory diagram of a list displayed on the display unit 25, in which list information of ID information of a slave unit that has called the master unit 2 and date / time information (recording date / time information) that has been called is displayed.

Upon receiving this display, when a predetermined display operation is performed by selecting a video column to be viewed from the display list on the touch panel, a selection display signal is transmitted to the recording device 3. The recording apparatus CPU 32 that has received this selection display signal returns a password request signal, and a password input screen is displayed on the display unit 25.
When the operator inputs a password registered in advance on the password input screen by touch panel operation or the like, the recording device CPU 32 collates it, and if it matches, the selected video is read from the storage unit 31 and the master unit 2 is read. Sent to. In this way, in the master unit 2, the received video is displayed on the display unit 25.

  Erasing the recorded video can be performed by the same operation as browsing, and is specifically performed as follows. First, the list information is displayed on the display unit 25 as in the case of browsing the recorded video. When a column to be erased is selected from the list in the displayed state and a predetermined erasing operation is performed, a selective erasure signal is transmitted to the recording device 3. The recording device CPU 32 that has received this selection / erasure signal returns a password request signal in the same manner as the video display control, and a password input screen is displayed on the display unit 25. The video selected by inputting the password on the password input screen is deleted from the storage unit 31.

Thus, since the recording device 3 records the visitor video imaged by the handset 1, the recorded video can be managed collectively, which helps to improve security. Further, it is not necessary to provide recording means for each parent device 2. Also, when playing back recorded video on the master unit 2, a list of recorded videos with the master unit 2 as the call destination is displayed first, so that the desired video can be displayed smoothly and the recorded video can be managed. It is easy, and since it is not possible to see the video when calling another base unit 2, privacy can be maintained.
In addition, since it is necessary to input a password to play / delete the recorded video, it is possible to prevent a third party from viewing or deleting the password and to protect privacy.
Furthermore, although video signals are transmitted to two locations at the same time, since the video is transmitted by multicast, the amount of data to be transmitted can be kept to a minimum, and other communications are not affected.

Note that the recorded video of the recording device 3 can be browsed / erased by connecting a dedicated recorded video operation means consisting of a personal computer or the like. It can be managed and is effective in improving security.
Moreover, although the said form demonstrated the case where both the subunit | mobile_unit 1 and the main | base station 2 were two or more, even if the subunit | mobile_unit 1 is one and the main | base station 2 is a several system, it records by the recording apparatus 3 collectively. The above system can be applied satisfactorily, and can be applied satisfactorily in a system including a plurality of master units 2.

Next, another example of the intercom system of the present invention will be described. The configuration differs from the above configuration in that the recorded video list creation form is different and the slave unit 1 from which the master unit 2 can obtain video is predetermined. Hereinafter, the system configuration including a plurality of slave units 1 and 2 is the same as that in FIG. 1 described above, and thus description thereof will be omitted. The description will focus on the operation of displaying a recorded video list.
The storage unit 31 of the recording device 3 stores a table of the slave unit 1 from which each master unit 2 can obtain video, and FIG. 3 shows an example of this table. Specifically, FIG. 3 shows a list of parent devices 2 associated with each child device 1 in a configuration including five child devices 1 and two parent devices 2.

When the parent device 2 is selected in the child device 1 and a calling operation occurs, the captured image of the camera 14 is transmitted to the called parent device 2 and the recording device 3 in the same manner as in the above embodiment. At this time, the caller's child device ID is attached to the video signal transmitted to the recording device 3.
Receiving the video signal, the recording device CPU 32 records the video in the storage unit 31 and stores the attached child device ID. Thereafter, when the call is finished and the video output from the camera 14 is finished, the recording is finished in the same manner as in the above embodiment.

When a predetermined browsing operation of the parent device operation unit 21 of the parent device 2 is performed on the video thus recorded, the parent device CPU 26 transmits a list request signal to the recording device 3. Receiving the list request signal, the recording device CPU 32 reads the slave unit 1 associated with the requesting master unit ID from the storage unit 31 and creates a list of captured images of the camera 14 of the associated slave unit 1. To base unit 2.
For example, if there is a browsing request from the parent device 2 with the parent device ID “1”, a list of videos recorded when the child device 1 with the ID “1”, “2”, and “3” receives a call operation from FIG. Is generated and transmitted to the parent device 2 and displayed on the display unit 25. Thus, a list similar to that shown in FIG.
In response to this display, the base unit 2 performs the same operation as described above, and inputs the password, whereby the video stored in the storage unit 31 is displayed on the display unit 25 of the base unit 2.

As described above, when the recorded video is played back, the recorded video of the camera 14 of the slave unit 1 associated with the master unit 2 is selected and a list is displayed, so that all the recorded videos of the specific slave unit 1 are displayed. Can be confirmed by the same base unit 2, and it is easy to confirm a suspicious person, etc., and helps to improve security.
In addition, since all recorded videos cannot be viewed from a single parent device 2, it is effective in maintaining the privacy of the recorded videos.

  In the above embodiment, the case where it is installed in an office building has been described as an example. However, the intercom system of the present invention can be applied to an intercom in a general house, and has a function of selecting and calling a household as in a two-family house. It is suitable when it is desired to provide it.
