  FIG. 3 shows the configuration of the pointing device 20. The pointing device 20 includes a communication unit 70, a identifying unit 72, and an instructing unit 74. The identifying unit 72 includes an area identifying unit 76 and an indoor device identifying unit 78. The indoor device identifying unit 78 includes a determining unit 80. The communication unit 70 communicates with each of the plurality of indoor devices 16 via the occupied trunk line 26. The communication unit 70 receives an alarm signal from the notification-side indoor unit 16 when an emergency occurs. As described above, the alarm signal includes identification information for identifying the indoor device 16. The communication unit 70 outputs an alarm signal to the identification unit 72.

  The area specifying unit 76 specifies an area in which the indoor device 16 as the output source of the alarm signal received by the communication unit 70 is installed. Here, the area is a unit obtained by dividing the inside of an apartment house into a plurality. An example of a zone is a floor number. The area specifying unit 76 extracts the identification information included in the alarm signal, and specifies the number of floors of the dwelling unit 14 in which the indoor device 16 is installed from the identification information. If the dwell unit number as the identification information is "603", the area identification unit 76 identifies "sixth floor" as the area. Thus, the area identification unit 76 identifies any one of the plurality of areas. The area specifying unit 76 outputs the information of the specified area to the indoor device specifying unit 78.

  The indoor device specifying unit 78 inputs information on the area from the area specifying unit 76. The indoor device specifying unit 78 specifies at least one indoor device 16 installed in the area specified by the area specifying unit 76. Here, the indoor devices 16 installed in the plurality of dwelling units 14 in the input floor number are identified.

  FIG. 4 shows an outline of processing in the indoor device identification unit 78. The outline of a plurality of dwelling units included in the apartment is shown in FIG. Since the apartment is nine floors from the first floor to the ninth floor, the aforementioned areas correspond to the first floor to the ninth floor, respectively. In addition, each floor includes dwelling units 14 of “10”, and an elevator EV is disposed at a central portion of each floor. The unit number of the unit 14 is indicated as "101". Furthermore, in the part of "101", an entrance such as a lobby of an apartment is arranged. If the identification information included in the alarm signal indicates the dwell unit number “603”, the area identification unit 76 identifies the sixth floor as the area. Furthermore, the indoor device identifying unit 78 identifies the dwelling units 14 of the dwelling unit numbers “601” to “610” included in the sixth floor. Return to FIG.

  As described above, when the area specifying unit 76 and the indoor device specifying unit 78 receive an alarm signal from the indoor unit 16 on the notification side, the area specifying unit 76 and the indoor device specifying unit 78 receive at least one reception to cause the imaging unit 58 included in the door phone 18 to start imaging. The indoor unit 16 on the information side is identified. Furthermore, the indoor device specifying unit 78 may specify the lobby intercom 10 and the additional camera 22. Whether to specify lobby intercom 10 and extension camera 22 may be determined according to the number of floors specified in area specifying unit 76. The indoor device identification unit 78 outputs information on the identified indoor device 16 to the instruction unit 74.

  The determination unit 80 determines an imaging period for each of the at least one indoor device 16 identified in the indoor device identification unit 78. The imaging period is set to be longer as the indoor device 16 installed in the dwelling unit 14 apart from the dwelling unit 14 in which the indoor unit 16 on the notification side is installed. On the other hand, the imaging period may be set to be longer as the indoor device 16 installed in the dwell unit 14 closer to the dwell unit 14 where the indoor unit 16 on the alert side is installed. Furthermore, the reference of the imaging period may be set based on the distance to the moving means to another floor such as an elevator or a stair. For example, the imaging period is set to be longer as the dwell unit 14 is closer to the elevator or the like. In the case of the first floor, the distance to the entrance may be used as a reference for the imaging period. In that case, the imaging period is set to be longer as the dwelling unit 14 is closer to the entrance. The determination unit 80 outputs the determined imaging period to the instruction unit 74.

  The instruction unit 74 inputs information related to the specified indoor device 16 from the indoor device specifying unit 78, and inputs an imaging period from the determination unit 80. The information on the identified indoor device 16 is, for example, indicated by a dwell unit number, and includes one or more dwell unit numbers. When a plurality of housing unit numbers are included, a plurality of imaging periods are also included, and the housing unit numbers correspond to the imaging periods on a one-to-one basis. Based on the correspondence, instruction unit 74 generates a combination of a dwell unit number and an imaging period, and generates an instruction signal including the generated combination. One instruction signal may include one combination, or may include multiple combinations. In the former case, a plurality of indication signals are generated for each of the plurality of combinations.

  The instruction unit 74 causes the communication unit 70 to transmit an instruction signal. Therefore, the instruction unit 74 instructs the at least one indoor device 16 specified in the specifying unit 72 via the communication unit 70 to perform imaging for a fixed period. The instruction unit 74 also instructs the imaging period determined by the determination unit 80.

  In terms of hardware, this configuration can be realized with the CPU, memory, or other LSI of any computer, and with software, it can be realized by a program loaded into the memory, etc. Are drawing functional blocks.
