The camera adapter 4 periodically extracts image signals from a plurality of imaging devices 3 connected to the camera adapter 4 and stores them in the memory 43. When the control unit 41 of the camera adapter 4 receives the transmission request signal from the control room master computer 1 by the communication unit 42, it reads out the image data of the specific time length contained in the imaging device 3 that transmits the request signal from the memory unit 43 . Then, the control unit 41 sends the image data of a specific time length from the communication unit 42 to the management room master computer 1 via the control device 5 (S5 in FIG. 4). When the communication unit 12 of the parent machine 1 of the management room receives the image signal from the camera adapter 4, the control unit 11 sends the call from the communication unit 12 via the control device 5 to the parent unit 2 of the called household (the parent unit 2 with the household number "1234") ) Send a call signal (S6 in Figure 4). When the communication unit 22 of the called household base machine 2 receives a call signal from the management room base machine 1 via the control device 5, it sends a response signal to the management room base machine 1 via the control device 5 (S7 in FIG. 4). When the communication section 12 of the parent machine 1 of the management room receives a response signal for the call signal from the parent machine 2 of the household, the control section 11 converts the image data of a specific time length received from the camera adapter 4 via the control device 5 into, for example, Animation files in compressed formats such as H.264 and MPEG-4 (Moving Picture Experts Group). Then, the control unit 11 sends the created animation file from the communication unit 12 to the called household base machine 2 via the control device 5 (S8 in FIG. 4). Here, when the communication unit 22 receives the call signal from the management room base unit 1, the control unit 21 of the household base unit 2 outputs a control command for outputting the call sound to the communication unit 25, and the communication unit 25 causes the call sound to be output from the speaker 252. In addition, when the communication unit 22 receives a call signal from the control room base unit 1, the control unit 21 displays a notification screen A3 (see FIG. 5) for notifying the call from the control room base unit 1 on the display unit 24.

The button B22 is used to select the button of the camera device 3B, and the machine name of the camera device 3B (for example, "camera 2") is displayed on the button B22. Button B23 is a button that is operated when answering a call from the master phone 1 of the management room, and the text "Talk" is displayed on button B23. Here, the residents of the household 102 watch the animation of the camera device 3 displayed on the notification screen A3, and when deciding not to answer the call from the receptionist, do not perform any operation of the household base machine 2 and do not send from the household base machine 2 The signal to start a call with the control room base phone 1. When the occupant is not in the household 102, the household base machine 2 also does not send a signal to start a call with the management room base machine 1. If there is no response from the resident, the receptionist judges whether the resident refuses to meet with the visitor or the resident is absent, and responds to the visitor. On the other hand, when the occupant of the called household 102 observes the animation of the camera device 3 displayed on the notification screen A3, and decides to answer the call from the receptionist, he operates the button B23 for talking (Figure 4 S9). When the control unit 21 of the household base unit 2 inputs the operation signal corresponding to the button B23 from the operation unit 23, the call request signal requesting the start of a voice call is sent from the communication unit 22 to the management room base unit 1 via the control device 5 (S10 in FIG. 4) ). Then, when the communication unit 12 of the management room base unit 1 receives the call request signal from the called home base unit 2, the control unit 11 transmits and receives voice signals between the home base unit 2 via the control device 5 (S11 in FIG. 4). In this way, the resident of the household 102 can watch the image of the shared entrance 101 displayed on the parent phone 2 of the household while talking with the receptionist. The residents of the household 102 can ask the visitor about the reason through the receptionist, or instruct the receptionist to guide the visitor to the exclusive area of the collective residence. At this time, the control unit 11 of the master computer 1 of the management room obtains the dynamic image made from the image of the imaging device 3 output from the camera adapter 4, synchronizes with the sound signal output from the microphone 151, and makes it self-communicate The part 12 is sent to the household base machine 2. For example, the control unit 11 of the control room main unit 1 performs synchronization processing to reduce the time difference between the moving image and the sound by staggering one or both of the moving image and the sound signal on the time axis. Thereby, the time deviation between the dynamic image captured by the camera device 3 separated from the main unit 1 of the management room and the sound signal output from the microphone 151 of the main unit 1 of the management room is suppressed, so that the occupants of the household 102 can view the dynamic image at the same time. It is not easy to feel uncomfortable when listening to a sound signal. Furthermore, the so-called synchronization between the moving image and the audio signal does not mean that the moving image and the audio signal are output at the same time, and the moving image can be output in a slightly delayed or advanced state relative to the audio signal. In addition, the control unit 11 of the control room main unit 1 includes the identification information of the imaging device 3 that is to be sent to send the image signal in the transmission request signal at a specific time interval, and the communication unit 12 passes the control device 5 to the camera adapter 4 Send (S12 in Figure 4). When the communication unit 42 of the camera adapter 4 receives the transmission request signal from the management room main machine 1, the control unit 41 reads from the memory unit 43 the specific time length of the imaging device 3 corresponding to the identification information contained in the transmission request signal Image information. Then, the control unit 41 sends the image data of a specific time length from the communication unit 42 to the management room master computer 1 via the control device 5 (S13 in FIG. 4). When the communication part 12 of the parent machine 1 of the management room receives the image data of a specific length of time, the control part 11 converts the image data of the specific length of time into an animation file, and sends the converted animation file to the parent machine of the called household 2. In this way, from the management room base machine 1 to the household base machine 2, the animation files are sent at specific time intervals, and the animation files are played in the household base machine 2, so the resident using the household base machine 2 can confirm the image of the shared hallway 101 while performing call. If the animation created based on the image of the camera device 3A is displayed on the display portion 24 of the home phone 2 and the occupant operates the touch button B22, the image based on the camera device 3B can be created The animation is displayed on the display part 24 of the household base machine 2. When the occupant operates the touch button B22, the operation unit 23 outputs the operation signal of the button B22 to the control unit 21. The control unit 21 transmits a request signal for requesting an image of the imaging device 3B to the management room parent machine 1 via the control device 5 based on the operation signal of the button B22. When the communication unit 12 of the management room main unit 1 receives the request signal for the image of the imaging device 3B from the household main unit 2, the control unit 11 causes the request signal for the image of the imaging device 3B to be transferred from the communication unit 12 to the camera via the control device 5. Receiver 4 sends. When the communication unit 42 of the camera adapter 4 receives the request signal from the control room main machine 1, the control unit 41 reads out the image data of the camera device 3B for a specific time length from the memory unit 43, and sends the camera device 3B to the specific time The image data of the length is sent from the communication unit 42 to the control room master computer 1 via the control device 5. When the communication part 12 of the master computer 1 of the management room receives the image data of the specific time length of the camera device 3B, the control part 11 converts the image data of the specific time length of the camera device 3B into an action file. Then, the control unit 11 sends the converted animation file from the communication unit 12 to the called household base machine 2 via the control device 5, and displays the image of the camera device 3B on the household base machine 2. After the call is made between the occupant of the household 102 and the receptionist, if the operation section 13 of the base unit 1 of the management room or the operation section 23 of the base unit 2 of the management room performs an operation to end the voice call, the control section 11 of the base unit 1 of the management room And the control unit 21 of the home base phone 2 performs processing to end the voice call. However, there are cases where the receptionist calls the residents of the household 102 in order to convey to the residents several reasons other than the visitor's visit. In this case, in the call screen A2, the receptionist only needs to operate the button B13 for making a call to the home base machine 2 without sending an image signal to the home base machine 2. When the receptionist operates the button B13 in the call screen A2, the operation unit 13 outputs the household number information of the called household 102 and the information indicating that the second call operation has been accepted to the control unit 11 as operation information. At this time, the image signal of the camera device 3 is not sent from the management room main machine 1 to the household main machine 2, but only audio signals are sent and received between the management room main machine 1 and the household main machine 2. Therefore, the image of the camera devices 3A and 3B are not displayed on the display portion 24 of the home base machine 2, and the receptionist and the residents of the home 102 only make voice calls. As described above, in the state where the call screen A2 is displayed on the display section 14 of the management room base machine 1, if the button B12 is operated, the image of the camera device 3A or 3B is displayed on the display section 24 of the household base machine 2. Therefore, the occupant of the household 102 can view the display on the display unit 24 to confirm the visitor before answering the call from the parent machine 1 of the management room. Therefore, the resident of the household 102 can confirm the image of the visitor and the receptionist in a state where their own information is not known to the visitor. In addition, since the camera devices 3A and 3B are configured separately from the management room main unit 1 and are arranged in the common entrance 101, it is not easy to manage the viewing angles of the camera devices 3A and 3B as in the case where the camera devices 3A and 3B are installed in the management room main unit 1 Restrictions on the installation location of the main room machine 1. If the camera devices 3A, 3B are installed in places where the visitor is not easy to notice, the visitor will not easily notice the images taken by the camera devices 3A, 3B, so the visitor is warned or the visitor feels less likely to feel uncomfortable. In addition, the occupant of the called household 102 can change the camera device 3A, which displays the image on the notification screen A3 by operating the buttons B21 and B22 while the notification screen A3 is displayed on the display part 24 of the household base machine 2. 3B.
