[0005] Patent Document 1: Japanese Patent Application Publication No. 2009-24427 Summary of the Invention

[0006] [The problem the invention aims to solve]

[0007] Smart keys, which unlock or lock doors electronically without the use of mechanical keys, are becoming increasingly common. To balance security and convenience when using smart keys to enter a residence, the inventors believe it is necessary to switch security levels based on whether the person entering is a resident or an outsider.

[0008] This disclosure was made in view of the above issues, and one object of it is to provide a technology that balances security and convenience when using a smart key to enter a residence.

[0009] [Technical solutions used to address technical problems]

[0010] To address the aforementioned issues, one proposed solution for a residential building intercom system includes: a shared intercom and a first reading device installed in the shared entrance hall of the residential building; individual intercoms installed in each unit of the residential building; and a first control device for controlling at least the shared intercom and the individual intercoms. The shared intercom captures images of people present in the shared entrance hall. When the first reading device receives an authentication operation performed by a person using a smart key, it sends authentication information related to that person to the first control device. The first control device (1) determines whether the person is a resident or a visitor based on the authentication information; (2) if the person is determined to be a resident, it sends an unlock signal to the shared entrance hall door; (3) if the person is determined to be a visitor, it outputs content from the shared intercom prompting the visitor to input a room number. Upon inputting the room number into the shared intercom, it sends an unlock signal to the shared entrance hall door and sends the image capture result from the shared intercom to the individual intercom corresponding to the input room number.

[0011] Other solutions disclosed herein are also residential intercom systems for multi-family homes. The multi-family residential intercom system includes: a shared intercom and a reading device installed in the shared entrance hall of the multi-family home; individual intercoms installed in each resident's home; and a control device that controls at least the shared intercom and the individual intercoms. When the reading device receives an authentication operation performed by a person using a smart key, it sends authentication information related to the person to the control device. The control device (1) determines whether the person is a resident of the multi-family home or a visitor based on the authentication information, and (2) if the person is determined to be a visitor, it causes the shared intercom to photograph the visitor for a specified period and sends the photographing result from the shared intercom to the individual intercom.

[0012] Another solution disclosed herein is a residential intercom system for multi-family homes. This multi-family residential intercom system includes: a camera and a reader installed in the common entrance hall of the multi-family home; intercoms installed in each unit of the multi-family home; and a control device that controls at least the camera and the intercoms. When the reader is input with an authentication operation performed by a person using a smart key, it sends authentication information related to the person to the control device. The control device (1) determines whether the person is a resident of the multi-family home or a visitor based on the authentication information, and (2) if the person is determined to be a visitor, it causes the camera to take a picture of the visitor for a specified time and sends the picture result to the intercom.

[0013] Another aspect of this disclosure is a residential intercom system. This residential intercom system includes: an entrance intercom and a reading device installed in the entrance hall of the residence; an indoor intercom installed inside the residence; and a control device for controlling at least the entrance intercom and the indoor intercom. When the reading device receives an input of a smart key unlocking operation performed by a person, it sends authentication information related to the person to the control device. The control device (1) determines whether the person is a resident or a visitor based on the authentication information; (2) if the person is determined to be a resident, it sends an unlocking signal to the entrance hall door; (3) if the person is determined to be a visitor, it begins taking photos of the visitor via the entrance intercom, sends an unlocking signal to the entrance hall door, and sends the photos taken by the entrance intercom of the visitor to the indoor intercom.

[0014] Furthermore, any combination of the above-mentioned constituent elements, or any manner of converting the present disclosure into an apparatus, method, computer program, or recording medium containing the computer program, is also valid as a form of the present disclosure.

[0015] [Invention Effects]

[0016] According to the technology disclosed herein, it is possible to balance security and convenience when using a smart key to enter a residence. Attached Figure Description

[0022] Figure 6 This is a diagram showing the configuration of a residential intercom system. Detailed Implementation

[0023] The main body of the apparatus or method disclosed herein includes a computer. The computer executes a program to achieve the function of the main body of the apparatus or method disclosed herein. As a primary hardware component, the computer includes a processor that operates according to a program. The processor is not limited in type as long as it can perform the function by executing the program. The processor consists of one or more electronic circuits, including integrated circuits (ICs) or large-scale integration (LSIs). These are referred to herein as ICs or LSIs, but the terminology varies depending on the degree of integration; they may also be called system LSIs, VLSIs (Very Large Scale Integration), or USLIs (Ultra Large Scale Integration). Field-programmable gate arrays (FPGAs) that are programmed after the LSI is manufactured can also be used for the same purpose, or reconfigurable logic devices capable of reconfiguring the internal bonding relationships or circuit partitioning within the LSI. Multiple electronic circuits can be integrated onto one chip or disposed on multiple chips. Multiple chips can be concentrated in one device or disposed on multiple devices. The program is recorded on a non-transitory recording medium such as a computer-readable ROM (Read Only Memory), optical disc, or hard disk drive. The program can also be pre-stored on the recording medium or supplied to the recording medium via a wide area network, including the Internet.

[0024] In this embodiment, a technology is proposed that balances security and convenience when entering and exiting a multi-family residential building with shared and private areas. The intercom system for this multi-family residential building switches security levels based on whether the person entering or exiting the shared or private area is a resident or a non-resident (hereinafter also referred to as a "visitor"). Visitors include not only relatives and friends of residents but also various service providers (service personnel). Service personnel include, for example, postal or delivery personnel, managers of household services, and in-home caregivers.

[0025] Figure 1 This illustration shows the configuration of the apartment intercom system 20 in an embodiment. The apartment 10 in which the intercom system 20 is constructed is an apartment building including dedicated units 12, common units 14, and a common entrance hall 16. Dedicated units 12 are private spaces for residents of the apartment 10. The apartment 10 includes multiple dedicated units 12 (residents). Common units 14 are spaces shared by multiple residents of the apartment 10, including, for example, a lobby or corridor, an elevator, etc. The common entrance hall 16, also called a shared entrance hall, is an entrance space shared by multiple residents of the apartment 10.

[0026] An indoor intercom 30 is installed in the dedicated unit 12 as an intercom for use by the residents of the dedicated unit 12. The indoor intercom 30 may also be referred to as a resident intercom. The indoor intercom 30 includes at least a display unit and a speaker. The display unit displays images of visitors captured by the shared intercom 24 and the outdoor intercom 34. The speaker outputs a ringtone for calling within the resident's unit.

[0027] A shared entrance hall 16 is equipped with a shared entrance hall door 22, a shared intercom 24, and a shared entrance hall reader 26. The shared entrance hall door 22 is a door device separating the shared entrance hall 16 from the common area 14. The shared intercom 24 is an intercom shared by multiple residents and visitors of the apartment complex 10. The shared intercom 24 includes at least an input section for entering room numbers, etc., and a camera for photographing people present in the shared entrance hall 16.

[0028] The shared entryway reader 26, acting as the first reader, wirelessly communicates with the smart key 42 (described later) to read data (authentication information in this embodiment) from the smart key 42. The shared entryway control device 28, acting as the first control device, communicates with the shared entryway door 22, the shared intercom 24, the shared entryway reader 26, and the indoor intercom 30, and controls these devices. In the apartment complex 10, indoor intercoms 30 are installed in each of the multiple dedicated units 12 (residents). The shared entryway control device 28 manages the multiple indoor intercoms 30 corresponding to the multiple dedicated units 12 (residents) by associating them with the identification number (room number in this embodiment) of each resident.

[0029] The entrance hall of the dedicated unit 12 (hereinafter also referred to as the "resident's entrance hall") is equipped with a resident's entrance hall door 32, an outdoor intercom 34, and a resident's entrance hall reading device 36. The resident's entrance hall door 32 is a door device that separates the dedicated unit 12 from the common unit 14; in other words, it is a door device that separates the inside and outside of the resident's home. The outdoor intercom 34, also referred to as the resident's entrance hall intercom, is an intercom shared by the residents of the dedicated unit 12 and visitors. The outdoor intercom 34 includes at least a camera for photographing people present in the resident's entrance hall.

[0030] The resident entryway reader 36, acting as a second reader, wirelessly communicates with the smart key 42 (described later) via short-range wireless communication to read data (authentication information in this embodiment) from the smart key 42. The resident entryway control device 38, acting as a second control device, communicates with the resident entryway door 32, the outdoor intercom 34, the resident entryway reader 36, and the indoor intercom 30, and controls these devices. In this embodiment, the resident entryway control device 38 is integrated with the indoor intercom 30; in other words, the functions of the resident entryway control device 38 are incorporated into the indoor intercom 30.

[0031] The smart key 42 is a smart key application imported into the smartphones held by residents or visitors of the apartment complex 10. As a variation, the smart key 42 can also be a dedicated smart key device. The smart key 42 includes at least a communication unit and a storage unit. The communication unit communicates wirelessly with the shared entryway reader 26 and the resident entryway reader 36 over a short range.

[0032] The storage unit of the smart key 42 stores authentication information pre-assigned to the holder of the smart key 42. The authentication information may be data unique to each holder of the smart key 42 (e.g., a resident or visitor of the residential complex 10), such as a key code. In this embodiment, the authentication information system assigned to residents of the residential complex 10 differs from the system assigned to visitors. Therefore, based on the value shown by the authentication information read from the smart key 42, it is possible to identify whether the holder of the smart key 42 is a resident or a visitor of the residential complex 10.

[0033] Storage device 40 is a memory device that stores data referenced or updated by the shared entrance control device 28 and the resident entrance control device 38. Storage device 40 stores formal authentication information pre-assigned to multiple residents and legitimate visitors of the apartment complex 10. The authentication information can also be stored in correspondence with the identification information of the assigned resident or visitor, i.e., the resident or visitor can be uniquely identified based on the authentication information. Additionally, storage device 40 can also store permission information indicating permission to enter the shared area 14 and permission information indicating permission to enter the private area 12, corresponding to the visitor's authentication information. This permission information can also be registered and changed by the residents of the apartment complex 10.

[0034] Additionally, storage device 40 stores data (also known as video recording data) of the footage captured by shared walkie-talkie 24 and outdoor walkie-talkie 34. The captured data stored in storage device 40 is provided to external devices such as the terminal of the administrator of the residential complex 10 and the terminal of a security service company. The location of storage device 40 is not limited; it can be installed within the residential complex 10 or at a remote location (such as a cloud service or data center).

[0035] The operation of the above-described intercom system 20 for multi-family residential buildings will be explained.

[0036] Figure 2 This is a flowchart illustrating the operation of the residential intercom system 20. The diagram shows the actions related to unlocking the common entrance door 22 of the common entrance hall 16. The processing of each device described below can also be implemented by the computer program stored in each device. The CPU of each device can also implement the processing by reading the computer program into main memory and executing it.

[0037] The shared intercom 24 remains in standby mode until a pre-defined call operation is input (S10: No). If a pre-defined call operation is input for the shared intercom 24 (S10: Yes), the shared intercom 24 begins the process of photographing a person present in the shared entrance 16 (hereinafter also referred to as the "authentication subject") (S11). The authentication subject may be a resident of the apartment complex 10 or a visitor. In this embodiment, the call operation is the operation of the call button on the shared intercom 24 by the authentication subject. If the shared intercom 24 accepts the operation of the call button, the photographing process by the built-in camera begins.

[0038] The shared intercom 24 notifies the shared entryway control device 28 that recording has begun, and the shared entryway control device 28 controls the shared entryway reader 26 to be in a state capable of accepting authentication operations (S12). In this embodiment, the authentication operation is the operation of the person being authenticated bringing the smart key 42 (e.g., a smartphone with the smart key application activated) close to the shared entryway reader 26.

[0039] If the authentication operation performed by the user using the smart key 42 is not entered within the specified time, in other words, if short-range wireless communication with the smart key 42 is not initiated within the specified time (S13 No), the shared access reading device 26 skips the subsequent processing and ends the flow of this diagram. If the authentication operation performed by the user using the smart key 42 is entered, in other words, if short-range wireless communication with the smart key 42 is initiated (S13 Yes), the shared access reading device 26 reads the authentication information related to the user stored in the smart key 42 (S14).

[0040] The shared entryway reader 26 sends the authentication information read from the smart key 42 to the shared entryway control device 28. The shared entryway control device 28 compares the valid authentication information stored in the storage device 40 with the authentication information received from the shared entryway reader 26 to determine whether the authentication information received from the shared entryway reader 26 is valid. If the authentication information received from the shared entryway reader 26 is valid, the shared entryway control device 28 determines whether the person being authenticated is a resident of the apartment complex 10 or a visitor based on the value shown in the authentication information (S15). Furthermore, if the shared entryway control device 28 determines that the person being authenticated is a visitor based on the authentication information, it can also use the correspondence between the authentication information in the storage device 40 and the permission information indicating permission to enter the shared area 14 as a further condition to perform the processing after S19 described later.

[0041] If the person to be authenticated is determined to be a resident of the apartment complex 10 (S16), the shared entrance control device 28 sends an unlock signal to the shared entrance door 22, enabling the shared entrance door 22 to open (S17). Additionally, the shared entrance control device 28 terminates the recording process performed by the shared intercom 24 (S18). If the person to be authenticated is a resident, the data from the shared intercom 24's recording (also referred to as video data of the resident) may be deleted without being saved. Alternatively, the shared entrance control device 28 may obtain the recording data from the shared intercom 24 and store it in the storage device 40, corresponding to the authentication information of the person to be authenticated (or the resident's identification information determined by the authentication information).

[0042] If the person being authenticated is determined to be a visitor (S16 No), the shared entrance control device 28 controls the shared intercom 24 to display a message prompting the visitor to enter a room number on the display unit, or to output the message via a speaker (S19). The shared intercom 24 receives the room number entered by the person being authenticated (hereinafter referred to as the visitor) into the input unit and sends the entered room number to the shared entrance control device 28 (S20). If the shared entrance control device 28 receives the room number from the shared intercom 24, it sends an unlock signal to the shared entrance door 22, enabling the shared entrance door 22 to open (S21).

[0043] Next, the shared entryway control device 28 ends the recording process performed by the shared intercom 24 (S22). The shared entryway control device 28 obtains the recording result data (also known as the video recording data of the visitor) from the shared intercom 24 and associates the recording result data with the room number entered by the visitor (S23).

[0044] The shared entryway control device 28 sends the captured data to the intercom 30 corresponding to the room number entered by the visitor (S24). The intercom 30 displays the captured data on the display unit. Thus, residents of the apartment the visitor will subsequently visit can confirm the visitor's image. The captured data sent to the intercom 30 may also include the visitor's authentication information (or the visitor's identification information determined by the authentication information). Furthermore, the shared entryway control device 28 stores the captured data, along with the visitor's authentication information (or the resident's identification information determined by the authentication information) and the room number entered by the visitor, in the storage device 40.

[0045] Figure 3 This is also a flowchart illustrating the operation of the residential intercom system 20. The diagram shows the actions related to unlocking the entrance door 32 of a specific resident (hereinafter also referred to as "specific resident") in the residential complex 10. The resident entrance reading device 36 remains in standby mode until an unlocking operation using the smart key 42 is entered by the person wishing to enter the specific resident (also referred to as "authentication target") (S30 no). The unlocking operation using the smart key 42 can also be called an authentication operation for unlocking, such as the operation of bringing the smart key 42, set to unlocking mode, close to the resident entrance reading device 36.

[0046] When the unlocking operation performed by the authenticating subject using the smart key 42 is entered, in other words, when short-range wireless communication with the smart key 42 in unlock mode is started (S30), the resident entrance reading device 36 reads the authentication information related to the authenticating subject stored in the smart key 42 (S31).

[0047] The resident entryway reader 36 sends the authentication information read from the smart key 42 to the resident entryway control device 38. The resident entryway control device 38 compares the valid authentication information stored in the storage device 40 with the authentication information received from the resident entryway reader 36 to determine whether the authentication information received from the resident entryway reader 36 is valid. If the authentication information received from the resident entryway reader 36 is valid, the resident entryway control device 38 determines whether the person being authenticated is a resident of the apartment complex 10 or a visitor based on the value shown in the authentication information (S32). Furthermore, if the resident entryway control device 38 determines that the person being authenticated is a visitor based on the authentication information, it can also use the correspondence between the authentication information in the storage device 40 and the permission information indicating permission to enter the dedicated access unit 12 as a further condition to perform the processing after S35 described later.

[0048] If the person being authenticated is determined to be a resident of the apartment building 10 (S33), the resident entrance control device 38 enables the resident entrance door 32 to open by sending an unlocking signal to the resident entrance door 32 (S34).

[0049] If the person being authenticated is determined to be a visitor (S33 no), the resident entrance control device 38 controls the outdoor intercom 34 to begin the process of photographing the person being authenticated (hereinafter referred to as the visitor) (S35). Furthermore, the resident entrance control device 38 controls the indoor intercom 30 to perform a call from inside the resident's home (e.g., outputting a ringtone) (S36). The resident entrance control device 38 waits for a predetermined time (e.g., several seconds to tens of seconds) (S37), and then sends an unlocking signal to the resident entrance door 32, enabling the resident entrance door 32 to open (S38). By allowing a certain period of time from the call from inside the resident's home to the unlocking of the resident entrance door 32, residents can be mentally prepared for the visitor's entry.

[0050] Next, the resident entryway control device 38 finishes the recording process performed by the outdoor intercom 34 (S39). The resident entryway control device 38 obtains the recording data (also referred to as video data of the visitor) from the outdoor intercom 34 and associates the recording data with the room number of the specific resident the visitor wants to enter. The resident entryway control device 38 sends the recording data to the indoor intercom 30 (S40). The recording data sent to the indoor intercom 30 may also include the visitor's authentication information (or the visitor's identification information determined by the authentication information). In addition, the resident entryway control device 38 stores the recording data, the visitor's authentication information (or the resident's identification information determined by the authentication information), and the room number of the specific resident in the storage device 40.

[0051] Figure 4 This is also a flowchart illustrating the operation of the intercom system 20 for the apartment building. The diagram shows the operation related to locking the entrance door 32 of a specific resident (specific resident) in the apartment building 10. The entrance door reader 36 remains on standby until a locking operation using the smart key 42 is entered by someone who wants to exit the specific resident's apartment (also called the "authentication target") (S50: No). The locking operation using the smart key 42 can also be called an authentication operation for locking, such as the operation of bringing the smart key 42, set to lock mode, close to the entrance door reader 36.

[0052] When the user enters a lock operation using the smart key 42, in other words, when short-range wireless communication with the smart key 42 in lock mode is initiated (S50), the resident access reading device 36 reads the authentication information related to the user stored in the smart key 42 (S51).

[0053] The resident entryway reader 36 sends the authentication information read from the smart key 42 to the resident entryway control device 38. The resident entryway control device 38 compares the valid authentication information stored in the storage device 40 with the authentication information received from the resident entryway reader 36 to determine whether the authentication information received from the resident entryway reader 36 is valid. If the authentication information received from the resident entryway reader 36 is valid, the resident entryway control device 38 determines whether the person being authenticated is a resident of the apartment complex 10 or a visitor based on the value shown in the authentication information (S52). Furthermore, if the resident entryway control device 38 determines that the person being authenticated is a visitor based on the authentication information, it can also use the correspondence between the authentication information and the permission information of the access permission unit 12 as a condition to execute the processing after S55 described later.

[0054] If the person to be certified is a resident of the apartment building 10 (S53), the resident entrance control device 38 locks the resident entrance door 32 by sending a door locking signal to the resident entrance door 32 (S54).

[0055] If the person being authenticated is determined to be a visitor (S53 No), the resident entrance control device 38 controls the outdoor intercom 34 to begin the process of photographing the person being authenticated (hereinafter referred to as the visitor) (S55). The resident entrance control device 38 waits for a specified time (e.g., a few seconds to a dozen seconds) (S56), and then locks the resident entrance door 32 by sending a door locking signal to the resident entrance door 32 (S57). By allowing a certain amount of time until the resident entrance door 32 is locked, residents can be mentally prepared for the visitor to leave or for the resident entrance door 32 to be locked.

[0056] Next, the resident entryway control device 38 finishes the recording process performed by the outdoor intercom 34 (S58). The resident entryway control device 38 obtains the recording data (also referred to as video data of the visitor) from the outdoor intercom 34 and associates the recording data with the room number of the specific resident the visitor wants to lock. The resident entryway control device 38 sends the recording data to the indoor intercom 30 (S59). The recording data sent to the indoor intercom 30 may also include the visitor's authentication information (or the visitor's identification information determined by the authentication information). In addition, the resident entryway control device 38 stores the recording data, the visitor's authentication information (or the resident's identification information determined by the authentication information), and the room number of the specific resident in the storage device 40.

[0057] According to the embodiment, the residential intercom system 20 can switch security-related processing based on whether the person entering the common area 14 of the residential complex 10, the person entering and using the residential complex 10, or the person leaving the residential complex 10 is a resident of the residential complex 10 or a visitor. This balances security and convenience when entering and exiting the residential complex 10 using the smart key 42. Furthermore, when using the smart key 42 to unlock the common entrance door 22 or to unlock / lock the resident's entrance door 32, the security of the residential complex 10 can be further enhanced by storing the visitor's photographed data corresponding to the room number of the destination and providing this data to the indoor intercom 30 at the destination.

[0058] The present disclosure has been described above based on embodiments. Those skilled in the art should understand that these embodiments are merely examples, and various modifications may exist in the combination of the constituent elements or processing flows of the embodiments, and such modifications are also within the scope of this disclosure.

[0059] The first variation is explained. In the above embodiment, the shared walkie-talkie 24 begins photographing the person to be authenticated upon receiving a call button operation on the shared walkie-talkie 24 as a call operation. As a variation, the call operation may also be an operation of entering a registration number that has been pre-notified to the person to be authenticated (e.g., a resident or visitor). That is, the shared walkie-talkie 24 may also begin photographing the person to be authenticated upon receiving a registration number that has been pre-notified to the person to be authenticated.

[0060] Registration numbers can also be assigned unique numbers for each type of service provider (postal, housekeeping, etc.). The shared entryway control device 28 can also send and display data from the shared intercom 24, authentication information read from the visitor's smart key 42, and the registration number (or the type of service provider identified by the registration number) entered through the call operation on the indoor intercom 30. Furthermore, the shared entryway control device 28 can also correspondingly store the data from the shared intercom 24, authentication information read from the visitor's smart key 42, and the registration number (or the type of service provider identified by the registration number) entered through the call operation in the storage device 40.

[0061] As another variation, the shared intercom 24 may also begin the process of photographing people present in the shared entrance 16 without requiring input from a user-performed readout operation. For example, the shared intercom 24 may also automatically begin photographing a person (the person to be authenticated) if the camera detects that someone is in the shared entrance 16.

[0062] Explain the second variation. Figure 5 This is a flowchart illustrating the operation of a modified intercom system 20 for a multi-family dwelling. The diagram shows actions related to the recording of visitors to the shared entrance hall 16. The shared entrance hall reader 26 remains in standby mode until an authentication operation (S60) is performed using the smart key 42 by a person (also referred to as the "authentication target") wishing to enter the common area 14 from the shared entrance hall 16 of the multi-family dwelling 10.

[0063] When the shared entryway reader 26 receives an authentication operation performed by the authenticator using the smart key 42 (S60), it reads the authentication information related to the authenticator stored in the smart key 42 (S61). The shared entryway reader 26 sends the authentication information read from the smart key 42 to the shared entryway control device 28. The shared entryway control device 28 compares the valid authentication information stored in the storage device 40 with the authentication information received from the shared entryway reader 26 to determine whether the authentication information received from the shared entryway reader 26 is valid. If the authentication information received from the shared entryway reader 26 is valid, the shared entryway control device 28 determines whether the authenticator is a resident of the apartment complex 10 or a visitor based on the value shown in the authentication information (S62).

[0064] If the person to be authenticated is determined to be a visitor (as in S63), the shared entrance control device 28 controls the shared intercom 24 to begin filming the person to be authenticated (hereinafter referred to as the visitor) (S64). If a predetermined time has elapsed after the start of the filming process, the shared entrance control device 28 ends the filming process performed by the shared intercom 24 (S65). That is, the shared entrance control device 28 keeps the filming process of the visitor performed by the shared intercom 24 for a predetermined time.

[0065] The shared entryway control device 28 obtains the data of the captured images (also known as video data of the visitors) from the shared intercom 24 and sends the captured images to the indoor intercom 30 (S66). The destination of the captured images data can also be the same as that in the... Figure 5 In the process not shown in the diagram, the room number entered by the visitor corresponds to the indoor intercom 30. Additionally, the shared entrance control device 28 stores the captured data in the storage device 40.

[0066] If the person to be authenticated is determined to be a resident of the apartment complex 10 (No in S63), the subsequent processing is skipped and the process in this diagram ends. In this embodiment, the authentication process is performed only when the person to be authenticated is a visitor. In this modified example, the security-related processing is switched depending on whether the person entering the common area 14 of the apartment complex 10 is a resident of the apartment complex 10 or a visitor other than a resident, thus balancing security and convenience when using a smart key to enter the apartment complex 10.

[0067] The third variation is explained. The shared intercom 24 of the above embodiment has a built-in camera that captures images of people in the shared entrance 16. As a variation, the camera capturing images of people in the shared entrance 16 can also be installed in the shared entrance 16 as a separate device from the shared intercom 24. As a combination of the second and third variations, the shared entrance control device 28 can also control the camera, separate from the shared intercom 24, to capture images of the visitor for a specified period when it determines that the person to be authenticated is a visitor. The shared entrance control device 28 can also obtain the image capture data from the camera and send the image capture data to the indoor intercom 30.

[0068] The fourth variation is explained. The technology of the multi-family residential intercom system 20 of the above embodiment can also be applied to detached houses. Figure 6 This describes the configuration of the residential intercom system 50. The residential intercom system 50 is a technology that applies the technology described in the embodiment related to entering and exiting the dedicated unit 12 (resident) of the collective residential building 10 to entering and exiting the residential building 51, which is an independent residence.

[0069] Residence 51 includes a house 52 and an entrance hall 54. An intercom 62 for use by the residents of residence 51 is installed in the house 52. The intercom 62 has the same functions as the intercom 30 in the embodiment.

[0070] An entrance hall 54 is equipped with an entrance door 56, an outdoor intercom 58, and a reading device 60. The entrance door 56 separates the entrance hall 54 from the house 52. The outdoor intercom 58, also known as an entrance hall intercom, is shared by residents and visitors of the residence 51. The outdoor intercom 58 has the same functions as the outdoor intercom 34 in the embodiment. The reading device 60 has the same functions as the resident entrance hall reading device 36 in the embodiment.

[0071] The entryway control device 64 corresponds to the resident entryway control device 38 in this embodiment. The entryway control device 64 communicates with and controls the entryway door 56, the outdoor intercom 58, the reading device 60, and the indoor intercom 62. In this modified example, the entryway control device 64 and the indoor intercom 62 are integrated; in other words, the functions of the entryway control device 64 are incorporated into the indoor intercom 62.

[0072] The operation of the residential intercom system 50 described above will be explained.

[0073] First, the actions of a resident of residence 51 or a visitor (other than a resident) entering house 52 through entrance hall 54 will be explained. When the person entering house 52 (also referred to as the "authentication target") performs an unlocking operation using smart key 42, in other words, upon initiating close-range communication with smart key 42 in unlocking mode, reading device 60 reads the authentication information related to the authentication target stored in smart key 42. Reading device 60 sends the authentication information read from smart key 42 to entrance hall control device 64. In this variation, the authentication information read from smart key 42 can also identify whether the holder of smart key 42 is a resident of residence 51 or a visitor.

[0074] The entryway control device 64 compares the legitimate authentication information stored in the storage device 40 with the authentication information received from the reading device 60 to determine whether the authentication information received from the reading device 60 is legitimate. If the authentication information received from the reading device 60 is legitimate, the entryway control device 64 determines whether the person being authenticated is a resident of the residence 51 or a visitor based on the value shown in the authentication information. Furthermore, if the entryway control device 64 determines that the person being authenticated is a visitor based on the authentication information, it can also use the correspondence between the authentication information and permission information indicating permission to enter the house 52 as a condition to perform subsequent processing.

[0075] If the person being authenticated is determined to be a resident of residence 51, the entrance control device 64 enables the entrance door 56 to open by sending an unlocking signal to the entrance door 56.

[0076] If the person being authenticated is determined to be a visitor, the entryway control device 64 controls the outdoor intercom 58 to begin photographing the person being authenticated (hereinafter referred to as the visitor). Simultaneously, the entryway control device 64 controls the indoor intercom 62 to perform an in-house call (outputting a ringtone, etc.). The entryway control device 64 remains on standby for a predetermined time (e.g., several seconds to tens of seconds), after which it sends an unlocking signal to the entryway door 56, enabling the entryway door 56 to open.

[0077] Next, the entryway control device 64 terminates the recording process performed by the outdoor intercom 58. The entryway control device 64 obtains the recording data (also referred to as video data of the visitor) from the outdoor intercom 58 and sends this data to the indoor intercom 62. The recording data sent to the indoor intercom 62 may also include the visitor's authentication information (or the visitor's identification information determined by the authentication information). Furthermore, the entryway control device 64 stores the recording data in the storage device 40, corresponding to the visitor's authentication information (or the resident's identification information determined by the authentication information).

[0078] Next, the actions of a resident or visitor of residence 51 when exiting from house 52 to entrance 54 will be explained. When the person exiting house 52 (also referred to as the "authentication subject") performs a locking operation using smart key 42, in other words, when short-range wireless communication with smart key 42 in lock mode is initiated, reading device 60 reads the authentication information related to the authentication subject stored in smart key 42. Reading device 60 then sends the authentication information read from smart key 42 to entrance control device 64.

[0079] As described above, the entryway control device 64 determines whether the person being authenticated is a resident of residence 51 or a visitor based on the authentication information received from the reading device 60. If the person being authenticated is determined to be a resident of residence 51, the entryway control device 64 locks the entryway door 56 by sending a door locking signal to the entryway door 56.

[0080] If the person being authenticated is determined to be a visitor, the entryway control device 64 controls the outdoor intercom 58 to begin taking a picture of the person being authenticated (hereinafter referred to as the visitor). The entryway control device 64 waits for a specified time (e.g., several seconds to tens of seconds), and then locks the entryway door 56 by sending a door lock signal to the entryway door 56.

[0081] Next, the entryway control device 64 terminates the recording process performed by the outdoor intercom 58. The entryway control device 64 obtains the recording data (also referred to as video data of the visitor) from the outdoor intercom 58 and sends this data to the indoor intercom 62. The recording data sent to the indoor intercom 62 may also include the visitor's authentication information (or the visitor's identification information determined by the authentication information). Furthermore, the entryway control device 64 stores the recording data in the storage device 40, corresponding to the visitor's authentication information (or the resident's identification information determined by the authentication information).

[0082] The residential intercom system 50 in this variation also achieves the same effect as the integrated residential intercom system 20 in the embodiment. For example, the residential intercom system 50 switches security-related processing based on whether the person entering or exiting the residence 51 using the smart key 42 is a resident or a visitor. Thus, both security and convenience when entering and exiting the residence 51 using the smart key 42 can be taken into account.

[0083] Any combination of the above embodiments and variations is also useful as an implementation of this disclosure. New implementations resulting from such combinations combine the effects of both the combined embodiments and variations. Furthermore, those skilled in the art should understand that the functions to be performed by the constituent elements recited in the claims are achieved through the individual elements shown in the embodiments and variations, or through their cooperation.
