The communication device 143 transmits / receives various information to / from the indoor parent device 10 and to the visitor terminal device 300.

  The HDD 110 stores a database. The database includes a business menu database (FIGS. 8 and 9 to be described later) that stores a plurality of business items that ask the visitor's purpose of visit, and is collected from each intercom device 1 in association with each of the multiple business items. A suspicious information database (FIG. 10 to be described later) for storing the suspicious information is provided. The contents stored in the business menu database and the suspicious information database are transmitted to each door phone device 1 via the network and stored in the storage unit 44 of the indoor parent device 10.

  Note that the circuit configuration of the visitor terminal device 300 is not shown. As the visitor terminal device 300, a general-purpose personal computer having a circuit configuration as shown in FIG. 6 or a mobile phone can be adopted.

  Next, the reservation information database will be described with reference to FIG.

  FIG. 7 shows a reservation information database provided in the door phone device 1. The reservation information database stores visit reservation information including a visitor name, a visitor's e-mail address, a scheduled visit date and time, and a visit purpose, and authentication information including a password and face authentication data in association with each other.

  The door phone device 1 acquires the visit reservation information transmitted from the visitor terminal device 300, and when an input for accepting the visit reservation information is performed by the responder, a password is generated and stored in advance. The information associated with the visitor name is read from the face authentication data. Then, the password and face authentication data (for example, the corresponding address) are registered in the reservation information database in association with the visit reservation information.

  As the data used as the password, an arbitrary character string made up of symbols and numbers can be adopted, but in this embodiment, a number string made up of a number randomly selected from the range of “0 to 9” is used. The face authentication data is data in which feature points such as the position, distance, shape, and skeleton of eyes, nose, and mouth are extracted from individual visitor face images. The face authentication is performed by matching the facial feature point included in the facial authentication data with the feature point extracted from the visitor's face imaged by the camera 57. In the reservation information database, each visit reservation information and authentication information are arranged on the basis of the scheduled visit date and time, and the data can be given any configuration.

  Next, the business menu database will be described with reference to FIGS.

  FIG. 8 shows the main business menu database. FIG. 9 shows a sub business menu database. In the present embodiment, a plurality of main item items (main item information) and a plurality of sub item items (sub item information) that are subordinate concepts of each main item item are stored as associated item items. is doing. In the example shown in the figure, each item is separately shown, but is managed as a database. In the present embodiment, the visitor is caused to select any of the plurality of main item items, and subsequently, to select any of the plurality of sub item items related to the selected main item item. Thus, the visit purpose of the visitor is specified in more detail.

  The main message menu database stores a plurality of main message items and a main message ID that is information for identifying each main message item. The main item is information for asking the visit purpose of the visitor. For example, contents such as “home delivery (main item ID: 1)” and “solicitation (main item ID: 2)” are stored. Yes.

  The sub-item menu database stores a plurality of sub-items and a sub-item ID that is information for identifying each sub-item in accordance with each main item. The sub-requirement item is information for asking a visitor's purpose of visit by a lower-level concept in relation to the main requirement item (that is, for classifying in more detail). “Pizza (sub-item ID: 11)” in relation to “Subject ID: 1)”, “Religion (sub-item ID: 21)” in relation to “Solicitation (main item ID: 2)”, Contents such as “insurance (sub business ID: 22)” and “newspaper (sub business ID: 23)” are stored.

  Next, the suspicious information database will be described with reference to FIG.

  The suspicious information database stores suspicious information, time information, and position information in accordance with each of the plurality of item items (more specifically, main item ID and sub item ID). .

  The suspicious information is data that is input as a result of the visitor being evaluated by the respondent in the residence where each of the plurality of door phone devices 1 is installed. The suspicious information is collected from the plurality of door phone devices 1 via the network. The content of the suspicious information includes, for example, the evaluation of the respondent to the suspicious person such as “There was persistent solicitation” or “I am afraid of tone”.

  The time information is data indicating the date and time when the suspicious information was input by the respondent. For example, “year / month / date hour / minute / second” is stored. The suspicious information database is collated based on the current date and time, and suspicious information related to the date and time within the predetermined period from the current date and time (for example, within the past one week) and the same time zone (for example, 15:00 to 17:00) If the suspicious information is acquired, the suspicious person's information related to the current date and time is known, and the reliability as a material for determining whether or not to respond is increased.

  As the time information, the date and time when the suspicious information is input to the doorphone device 1 or the date and time when the management server 100 receives the suspicious information from the doorphone device 1 can be adopted. You can also use the date and time. There may be a case where the visitor does not input suspicious information immediately after the visitor has been treated, and it is possible to deal with a case where there is a gap between the date and time of the actual treatment and the entered date and time.

  The position information is data for specifying the position of the residence where the door phone device 1 to which the suspicious information is input is installed. For example, when the GPS is installed in the zip code or the door phone device 1, position data specified by the GPS can be adopted. If you check the suspicious information database based on the location information and obtain suspicious information about the residence (for example, within the range where the postal codes match), you can know and respond to the information of the suspicious person that appeared around the residence. Reliability as a material for determining whether or not is increased. In the suspicious information database, each suspicious information can be arranged according to each business item, and the data can be held in any manner.

  Next, the contents of a program executed by the CPU 31 of the indoor parent device 10 of the door phone device 1 will be described with reference to FIGS.

  First, with reference to FIG. 11, the indoor main unit main flowchart executed by the CPU 31 of the indoor base unit 10 will be described.

  First, the CPU 31 of the indoor parent device 10 determines whether or not there is an input from the indoor parent device 10 (S1). Specifically, it is determined whether or not an operation input by the respondent is detected by the touch panel 14. When it is determined that there is an input from the indoor parent device 10, the CPU 31 performs various setting processes (S2). For example, various settings such as browsing display of visit reservation information, registration of face authentication data, registration of position information (for example, zip code) of the door phone device 1, adjustment of the volume output from the speaker 11 of the indoor base unit 10, etc. Processing is performed.

  On the other hand, when it is determined that there is no input from the indoor parent device 10 in S1, the CPU 31 determines whether there is an input from the front door device 50 (S3). Specifically, it is determined whether or not an input notification signal is received from the entrance terminal 50 via the communication I / F 43. When detecting that the call button 55 has been pressed by the visitor or an operation input by the visitor is detected by the touch panel 14, the CPU 81 of the entrance child device 50 transmits an input notification signal to the indoor parent device 10 via the communication I / F 94. Like to do.

  If the CPU 31 determines that there is no input from the entrance cordless handset 50, it proceeds to S1 described above. On the other hand, when the CPU 31 determines that there is an input from the entrance cordless handset 50, the CPU 31 performs visitor confirmation processing described later with reference to FIG. 12 (S4). When this process is performed, the process proceeds to S1 described above.

  Next, a visitor confirmation process is demonstrated with reference to FIG.

  First, the CPU 31 of the indoor base unit 10 displays a screen (see (1) in FIG. 3) asking whether there is a reservation on the monitor 53 of the front door unit 50 (S21). The visitor is made to input the presence / absence of reservation by touching either “with reservation” or “without reservation” displayed on the monitor 53 with a fingertip or the like. An announcement asking whether there is a reservation may be output from the speaker 51.

  Next, CPU31 discriminate | determines whether there existed the input of the presence or absence of the reservation in the entrance subunit 50 (S22). When it is determined that there is no input, the CPU 31 proceeds to S22 and waits until there is an input. On the other hand, when determining that there is an input, the CPU 31 acquires the input content (S23). Specifically, the CPU 31 acquires information indicating whether or not there is a reservation input by the visitor at the entrance terminal 50 via the communication I / F 43. When the touch panel 54 detects an input made by a visitor, the entrance terminal 50 transmits a signal corresponding to the detected input content to the indoor base unit 10 via the communication I / F 94.

  Next, the CPU 31 determines whether or not “reserved” is input (S24). When the CPU 31 determines that there is an input of “reserved”, it performs an authentication process described later with reference to FIG. 13 (S25). In the authentication process, authentication information (password and face image data) acquired from a visitor is checked against authentication information registered in the reservation information database.

  Next, the CPU 31 determines whether or not the password and the face image are a correct combination (S26). In other words, the password acquired from the visitor matches the password registered in the reservation information database, and the face authentication data extracted from the face image data acquired from the visitor is registered in the reservation information database. It is determined whether or not the face authentication data being matched.

  When the CPU 31 determines that the password and the face image are not a correct combination, the CPU 31 notifies the entrance slave device 50 that the password is not authenticated (S27). When the entrance terminal 50 receives a signal indicating that the authentication is not performed, the entrance terminal 50 displays that fact on the monitor 53.

  The CPU 31 performs a menu selection process which will be described later with reference to FIG. 14 after S27 or when it is determined in S24 that “no reservation” has been input (S28). In the menu selection process, a process is performed in which a visitor selects any one of the plurality of item items, suspicious information related to the selected item item is acquired from the database, and displayed on the monitor 13. When this process is performed, the visitor confirmation process is terminated.

  On the other hand, when the CPU 31 determines in S26 that the password and the face image are a correct combination, the CPU 31 notifies the entrance slave device 50 that the password has been authenticated (S29). When the entrance terminal 50 receives a signal indicating that it has been authenticated, it displays that fact on the monitor 53.

  Next, the CPU 31 enters a call state with the front door 50 (S30). Voices collected by the microphone are exchanged between the indoor parent device 10 and the entrance child device 50, and are output by the speaker, so that a call between the respondent and the visitor is performed. At this time, the image of the visitor imaged by the camera 57 of the front door unit 50 is displayed on the monitor 13 of the indoor base unit 10. Next, the CPU 31 deletes the visitor record from the reservation information database (S31). The visit reservation information and the authentication information registered in the reservation information database are cleared.

  Next, the CPU 31 determines whether or not there is an input to end the call (S32). The CPU 31 displays an item indicating “end of call” on the monitor 13 after the above S30, and determines whether or not the input of “end of call” is detected by the touch panel 14. When the CPU 31 determines that there is no call end input, it waits until there is a call end input. On the other hand, when the CPU 31 determines that there is an input for ending the call, the CPU 31 enters a call disconnecting state with the front door 50 (S33). When this process is performed, the visitor confirmation process is terminated.

  Next, the authentication process will be described with reference to FIG.

  First, the CPU 31 of the indoor base unit 10 displays a screen requesting the visitor to input a password on the monitor 53 of the front door unit 50 (S41). A visitor is made to input a password by touching any one of “0” to “9” displayed on the monitor 53 with a fingertip or the like.

  Next, CPU31 discriminate | determines whether there existed the input of the password and the visitor's face image in the entrance subunit 50 (S42). The password is acquired by the touch panel 54, and the visitor's face image is acquired by the camera 57. When it is determined that there is no input, the CPU 31 proceeds to S42 and waits until there is an input. On the other hand, when determining that there is an input, the CPU 31 acquires the input content (S43). In the front door device 50, when a visitor is imaged by the camera 57, the captured image data is transmitted to the indoor parent device 10 via the communication I / F 94.

  Next, the CPU 31 collates the password and face image with the reservation information database (S44). CPU31 collates the password input by the visitor with the password registered in the reservation information database. Further, the CPU 31 selects image data suitable for recognizing the visitor's face portion from the visitor image data captured by the camera 57 by the personal verification control unit 47, and the image of the selected face portion. Extract feature points such as eye, nose, mouth position, distance, shape, and skeleton from the data. The data from which the feature points are extracted is collated with face authentication data registered in the reservation information database. When this process is performed, the authentication process is terminated.

  Next, menu selection processing will be described with reference to FIG.

  First, the CPU 31 of the indoor parent device 10 displays a service menu on the front door device 50 based on the service menu database (S51). Specifically, the CPU 31 displays a plurality of item items (including a main item item and a sub item item) stored in the storage unit 44 on the monitor 53 of the front door device 50.

  First, as shown in FIG. 3 (3), a plurality of main item items such as “delivery”, “solicitation”, and “collection” are displayed on the monitor 53 of the entrance terminal 50. A visitor is made to input by touching each main item displayed on the monitor 53 with a fingertip or the like. Although not shown, for example, when “solicitation” is input, the screen is switched to a screen on which a plurality of sub-items such as “insurance” and “newspaper” are displayed. Then, the visitor is caused to input by touching each sub-item displayed on the monitor 53 with a fingertip or the like.

  Next, CPU31 discriminate | determines whether there existed the input of the requirement item in the entrance cordless handset 50 (S52). When it is determined that there is no input, the CPU 31 proceeds to S52 and waits until there is an input. On the other hand, when it is determined that there is an input, the CPU 31 acquires the input content (S53).

  Next, the CPU 31 performs a suspicious information acquisition process which will be described later with reference to FIG. 15 (S54). In the suspicious information acquisition process, a process of acquiring suspicious information related to the item selected by the visitor from the management server 100 is performed.

  Next, the CPU 31 determines whether or not suspicious information exists (S55). When the CPU 31 determines that there is suspicious information in the reply content from the management server 100, the CPU 31 displays the acquired suspicious information on the monitor 13 as shown in (2) of FIG. 2 (S56). In addition, as shown in (2) of FIG. 2, the visitor can interact with the visitor by touching one of the “call allowed” and “call rejected” displayed on the monitor 13 with a fingertip or the like. Lets you enter a decision on whether to do it. When there is no suspicious information, the suspicious information related to the item is not displayed on the monitor 13 and a display prompting input of either “call permission” or “call rejection” is made. .

  After determining that there is no suspicious information after S56 or when there is no suspicious information in S55, the CPU 31 determines whether or not “call permission” has been input (S57). When it is determined that “call rejection” has been input, the CPU 31 notifies the entrance terminal 50 that the call is rejected (S58). When the front cordless handset 50 receives a signal indicating that the call is rejected, it performs corresponding processing. For example, the monitor 53 of the entrance cordless handset 50 displays that it is out of office and that it cannot respond due to circumstances.

  On the other hand, when the CPU 31 determines that the “call permission” has been input, the CPU 31 enters a call state with the front door 50 (S59). Voices collected by the microphone are exchanged between the indoor parent device 10 and the entrance child device 50, and are output by the speaker, so that a call between the respondent and the visitor is performed.

  Next, the CPU 31 determines whether or not suspicious information exists (S60). When the CPU 31 determines that there is no suspicious information, that is, no suspicious information is displayed on the monitor 13, the menu selection process is terminated. On the other hand, when the CPU 31 determines that the suspicious information exists, the display of the suspicious information ends (S61).

  Next, the CPU 31 determines whether or not there is an input to end the call (S62). The CPU 31 displays an item indicating “end of call” on the monitor 13 after S59, and determines whether or not the input of “end of call” is detected by the touch panel 14. When the CPU 31 determines that there is no call end input, it waits until there is a call end input. On the other hand, when the CPU 31 determines that there is an input for ending the call, the CPU 31 enters a call disconnecting state with the front door 50 (S63). When this process is performed, the menu selection process is terminated.

  Next, the suspicious information acquisition process will be described with reference to FIG.

  First, the CPU 31 of the indoor base unit 10 transmits to the management server 100 the business item input by the visitor and the position information set in the indoor base unit 10 (S71). The position information is stored in the storage unit 44 of the indoor parent device 10.

  Next, the CPU 31 waits for a response from the management server 100 (S72). Next, the CPU 31 stores the reply content from the management server 100 (S73). When suspicious information related to the business item exists in the database, the suspicious information is returned from the management server 100 and stored in the storage unit 44.

  Next, the CPU 31 determines whether or not the reply content is an error (S74). When the CPU 31 determines that the reply content is not an error, the suspicious information acquisition process ends. On the other hand, when determining that the reply content is an error, the CPU 31 performs error processing (S75). The CPU 31 displays that an error has occurred on the monitor 13 of the indoor base unit 10. When this process is performed, the process proceeds to S71.

  Next, the server-side suspicious information return process executed by the CPU 131 of the management server 100 will be described with reference to FIG.

  First, the CPU 131 of the management server 100 waits for transmission from the indoor parent device 10 (S201). Next, the CPU 131 determines whether or not the transmission item from the indoor base unit 10 includes a requirement item and position information (S202).

  When the CPU 131 determines that the business item and the position information are not included, the CPU 131 returns an error to the indoor parent device 10 (S203). When this process is performed, the process proceeds to S201 described above.

  On the other hand, when the CPU 131 determines that the business item and the location information are included, the CPU 131 refers to the suspicious information database (FIG. 9), acquires the suspicious information based on the business item and the location information, A reply is sent to the base unit 10 (S204).

  At this time, the CPU 131 obtains suspicious information including position information for specifying the position of the house within a predetermined range from the position of the house specified by the received position information, among the suspicious information related to the business item. To do. Further, the CPU 131 refers to the date and time when the item item and the position information are received from the indoor parent device 10 and acquires suspicious information. That is, the CPU 131 acquires suspicious information that is suspicious information related to the business item and includes time information for specifying a date and time within a predetermined range from the received date and time. In addition, for the main business item included in the business item, the one that stores a large number of suspicious information among the multiple sub business items related to the main business item is selected with priority. It is also possible to obtain suspicious information related to the sub-item. When these processes are performed, the process proceeds to S201 described above.

  Next, the terminal device side visit reservation process executed by the CPU of the visitor side terminal device 300 will be described with reference to FIG.

  First, the CPU of the visitor side terminal device 300 determines whether or not the visitor name, the scheduled visit date and time, the visit purpose, and the contact information (email address) constituting the visit reservation information have been input (S301). When determining that there is no input, the CPU proceeds to S301 and waits until there is an input. On the other hand, when determining that there is an input, the CPU acquires the input content and transmits it to the management server 100 (S302).

  Next, the CPU waits for a response from the management server 100 (S303). Next, the CPU determines whether or not there is a reservation acceptance message in the reply content from the management server 100 (S304). If the CPU determines that there is no reservation acceptance message in the reply from the management server 100, the CPU proceeds to S301. On the other hand, when it is determined that there is a reservation acceptance message, the CPU displays a reservation acceptance message on the monitor (S305).

  Next, with reference to FIG. 18, the parent machine side reservation receiving process executed by the CPU 31 of the indoor parent machine 10 will be described.

  First, the CPU 31 of the indoor parent device 10 waits for transmission from the visitor terminal device 300 via the management server 100 (S81). Next, the CPU 31 determines whether the contents transmitted from the visitor terminal device 300 via the management server 100 include visit reservation information (including visitor name, scheduled visit date and time, purpose of visit, and contact information). Is determined (S82).

  When the CPU 31 determines that the visit reservation information is not included in the content transmitted from the visitor terminal device 300 via the management server 100, it returns an error to the management server 100 (S83). When this process is performed, the process proceeds to S81. On the other hand, when the CPU 31 determines that the visit reservation information is included in the content transmitted from the visitor terminal device 300 via the management server 100, it registers the visit reservation information in the reservation information database (S84). .

  Next, the CPU 31 returns a reservation acceptance message to the management server 100 (S85). The management server 100 transmits the returned reservation acceptance message to the visitor terminal device 300. When this process is performed, the process proceeds to S81.

  Next, with reference to FIG. 19, the master unit side reservation result reply process executed by the CPU 31 of the indoor master unit 10 will be described.

  First, the CPU 31 of the indoor base unit 10 determines whether or not there is visiting reservation information that has not returned permission or rejection in the reservation information database (S101). When the CPU 31 determines that there is no visit reservation information that has not been returned as a permission or rejection in the reservation information database, the CPU 31 waits until there is visit reservation information that has not been returned as a permission or rejection in the reservation information database.

  On the other hand, when the CPU 31 determines that there is visit reservation information that has not been returned as a permission or rejection in the reservation information database, the CPU 31 displays the corresponding visit reservation information on the monitor 13 (S102). As shown in (1) of FIG. 2, the visit reservation information is displayed on the monitor 13, and the visitor is allowed to touch either “acceptance acceptance” or “acceptance rejection” displayed on the monitor 13 with a fingertip or the like. Thus, a decision as to whether or not to interact with the visitor is input.

  Next, the CPU 31 determines whether or not “acceptance permission” has been input (S103). When the CPU 31 determines that there has been an acceptance permission input, it generates a password (S104). Next, the CPU 31 transmits an e-mail notifying permission of acceptance with the generated password to a contact (e-mail address) included in the visit reservation information (S105). Next, the CPU 31 registers the password and face authentication data in the reservation information database (S106). Note that information associated with the visitor name included in the visit reservation information is read from the face authentication data stored in a predetermined storage area of the storage unit 44 and registered in the reservation information database. When this process is performed, the process proceeds to S101.

  On the other hand, when the CPU 31 determines in S103 that there has been an input of acceptance refusal, it sends an email notifying acceptance refusal to the contact (mail address) included in the visit reservation information (S107). When this process is performed, the process proceeds to S101.

  Next, the suspicious information registration process executed by the CPU 31 of the indoor parent device 10 will be described with reference to FIG.

  First, the CPU 31 of the indoor parent device 10 determines whether or not there is an input from the indoor parent device 10 (S91).

When it is determined that there is no input from the indoor parent device 10, the CPU 31 moves to S91 and waits until there is an input.

  On the other hand, when the CPU 31 determines that there is an input on the indoor base unit 10 side, the item selected by the visitor, the positional information registered in the indoor base unit 10 and the input by the respondent The suspicious information is transmitted to the management server 100 (S92). When this process is performed, the process proceeds to S91.

  Next, a server-side suspicious information registration process executed by the CPU 131 of the management server 100 will be described with reference to FIG.

  First, the CPU 131 of the management server 100 waits for transmission from the indoor parent device 10 (S221). Next, the CPU 131 determines whether or not the transmission item from the indoor base unit 10 includes a business item, position information, and suspicious information (S222).

  When the CPU 131 determines that the business item, the position information, and the suspicious information are not included, the CPU 131 returns an error to the indoor parent device 10 (S223). When this process is performed, the process proceeds to S221 described above.

  On the other hand, when the CPU 131 determines that the business item, the position information, and the suspicious information are included, the CPU 131 associates the business item, the positional information, and the suspicious information with the suspicious information database (FIG. 9). Store (S224). When this process is performed, the process proceeds to S221 described above.

  As described above, the door phone apparatus 1 acquires visit reservation information including a visitor name and a scheduled visit date from a visitor, and associates authentication information (password and face authentication data) with the reservation information database ( Register in Figure 7). Then, when it is detected that the visitor has visited the entrance terminal 50, the visitor is asked whether there is a visit reservation, and the visitor's reply to the question is acquired. When a response indicating that there is a visit reservation is obtained, the visitor is requested to enter authentication information, and the authentication information entered by the visitor is collated with the authentication information registered in the reservation information database. . As a result of the collation, when the authentication information input by the visitor matches the authentication information registered in the reservation information database, the voice call with the visitor is controlled.

  That is, by acquiring visit reservation information from a visitor in advance, the identity of the visitor and the scheduled visit date and time can be grasped in advance. Then, by requesting the visitor to input authentication information associated with the visit reservation information, it is possible to respond to the visitor specified in advance. Accordingly, the responder can avoid having an opportunity to respond to a visitor whose identity is unknown, and as a result, the risk of contact with a suspicious person can be avoided as much as possible.

  Further, the door phone device 1 generates a password every time visit reservation information is acquired from a visitor, and registers the generated password in the reservation information database in association with the visit reservation information. The generated password is notified to the target visitor. Therefore, the security of the password can be increased, which is suitable for providing more reliable support to the respondent.

  In addition, when the door phone device 1 receives the visit reservation information transmitted from the visitor terminal device 300, the door phone device 1 determines on the monitor 13 of the indoor parent device 10 whether or not to allow the visitor to permit the visitor. Display the screen to ask. The door phone apparatus 1 registers the registration information in the reservation information database by associating the authentication information with the visit reservation information when an input to permit the visitor to permit the visit is made.

  That is, since the respondent can determine whether or not to accept the visit reservation information, the visitor who performs the response and the responder who does not perform the response can be assigned in advance. Therefore, it is suitable to respond to a visitor specified in advance, and more reliable support can be provided to the responder.

  Further, the door phone device 1 associates the face authentication data, which is the biometric authentication information of the visitor, with the password, which is authentication information different from the biometric authentication information, in the reservation information database in association with the visit reservation information acquired from the visitor. The face image data of the visitor registered and imaged by the camera 55 of the front door 1 and the password input by the visitor are collated with the reservation information database. Therefore, compared with the case where only one of them is employed, the security of the authentication information can be improved, and it is suitable for providing more reliable support to the respondent.

  In addition, the door phone device 1 receives a request when the authentication information input by the visitor does not match the authentication information registered in the reservation information database, or when a reply indicating that there is no visit reservation is acquired. The item is displayed on the monitor 53 of the entrance cordless handset 50, the requirement item is selected by the visitor, and the purpose of the visit is specified. Then, the suspicious information related to the item selected by the visitor is acquired from the suspicious information database (FIG. 10) provided in the management server 100 and displayed on the monitor 13 of the indoor parent device 10.

  That is, since the suspicious information history collected from a plurality of other intercom devices 1 is displayed to the respondent according to the item entered by the visitor, the information on the suspicious person who has appeared in another residence is known. Will be able to. Therefore, for visitors who have not been specified in advance, the visitor determines whether or not to respond to the visitor by referring to the requirement items entered by the visitor and related suspicious information. can do.

  Further, the suspicious information evaluated by the responder is registered in the suspicious information database in association with the item selected by the visitor. In other words, as a result of the interaction between the visitor and the visitor, if the visitor feels suspicious, the information may be stored in the suspicious information database in association with the item selected by the visitor. It becomes possible. Therefore, it is possible to improve the reliability of suspicious information as a material for determining whether or not to respond.

  Moreover, according to the door phone apparatus 1, based on the position information registered in the door phone apparatus 1, the suspicious information including the position information for specifying the position of the house within the predetermined range from the position of the house is obtained from the suspicious information database. Try to get. Therefore, since it becomes possible to know the information of the suspicious person who appears in the vicinity of the residence, it is possible to improve the reliability of the suspicious information that is used as a material for determining whether or not to respond.

  Further, according to the door phone device 1, based on the time information specifying the date and time of the suspicious information evaluated by the respondent, the suspicious information including the time information specifying the date and time within a predetermined range from the current date and time is included. Information is obtained from the suspicious information database. Therefore, in relation to the date and time when the visitor visited, for example, information on the suspicious person who appeared recently or information on the suspicious person who appeared at the same time zone can be known. The reliability of suspicious information used as the judgment material can be improved.

  Moreover, according to the door phone apparatus 1, as a plurality of item items that ask the visit purpose of the visitor, a plurality of main item items are associated with a plurality of sub-item items that are subordinate concepts of the main item items. I remember. Then, the visitor is made to select one of a plurality of main item items and to select one of a plurality of sub item items related to the selected main item item. That is, the responder can know the visit purpose of the visitor in more detail, and can help to determine whether or not to respond.

  Further, according to the door phone device 1, since the suspicious information is registered in the suspicious information database in association with the main business item and the sub business item selected by the visitor, it is possible to determine whether or not to respond. The reliability of suspicious information can be improved.

  As described above, according to the door phone device 1, while responding to a visitor specified in advance, the visitor who has not been specified in advance is responded to based on information input to the visitor. By making it possible to determine whether or not to perform, it is possible to provide more reliable support to the respondent.

  In the above-described embodiment, when the authentication information input by the visitor matches the authentication information registered in the reservation information database, the visitor's password is deleted (FIG. 12). s32) is not limited to this, and the following configuration can be adopted.

  As shown in FIG. 22, the reliability data indicating the visitor's evaluation in association with the visitor name is registered in the reservation information database, and the authentication information input by the visitor and the authentication registered in the reservation information database. When the information matches, the reliability data does not satisfy the threshold value (for example, when “1” to “5” are provided, “1” to “3” below “4”, etc.) You can also erase your password. In addition, as shown in FIG. 22, an expiration date for deleting the password can be set according to the reliability.

  In this case, a password generated once can be fixedly used for a visitor who has made a specific evaluation, such as a visitor to whom the responder trusts. Therefore, it is possible to eliminate troublesome operations such as management of authentication information in relation to a specific visitor, and it is possible to provide highly convenient support for the respondent.
