[Overview of surveillance system]
The whole image of the monitoring system according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an overview of the monitoring system according to the first embodiment. In the example illustrated in FIG. 1, 100 indicates a monitoring sensor, 200 indicates a monitoring server that receives monitoring information obtained by the monitoring sensor 100, and 300 indicates a user terminal that receives monitoring information from the monitoring server 200. Show. In the example illustrated in FIG. 1, as an example of the monitoring sensor 100, a monitoring camera 100a that captures a monitoring image, an interpersonal sensor 100b that detects the presence or absence of a person, and a doorphone 100c that detects whether or not a doorphone is pressed are illustrated. It was. In the example illustrated in FIG. 1, the connection device 400 such as a router connected to the Internet is also illustrated, and the monitoring sensor 100 is connected to the network via the connection device 400.

  In the example shown in FIG. 1, the case where the monitoring sensor 100 is connected to the network via the connection device 400 is shown, but the present invention is not limited to this, and the monitoring is not performed via the connection device 400. The sensor 100 may be directly connected to the network. In the example illustrated in FIG. 1, the monitoring camera 100a, the interpersonal sensor 100b, the door phone 100c, and the like are illustrated as an example of the monitoring sensor 100. However, the present invention is not limited thereto, and an arbitrary sensor is used. For example, a sensor mounted on a home appliance may be used. To explain with a more detailed example, a sensor for detecting opening / closing of a refrigerator door, a temperature sensor by air conditioning, or the like may be used.

  In the example illustrated in FIG. 1, the monitoring sensor 100 acquires monitoring information. For example, the monitoring camera 100a captures a monitoring image, the interpersonal sensor 100b detects whether or not a person is detected, and the doorphone 100c detects whether or not the doorphone is pressed. Then, the monitoring sensor 100 transmits monitoring information to the monitoring server 200 via the connection device 400.

  The monitoring server 200 stores the monitoring information transmitted by the monitoring sensor 100 in a predetermined storage unit, and transmits predetermined monitoring information among the stored monitoring information to the user terminal 300. The monitoring server 200 is owned, for example, by an operator that provides a service for transmitting monitoring information to the user terminal 300. For example, the monitoring server 200 stores specific conditions for specifying predetermined monitoring information to be transmitted to the user terminal 300 and transmits the monitoring information specified by the specific conditions to the user terminal 300. For example, the monitoring server 200 transmits the monitoring information retrieved from the user terminal 300 to the user terminal 300.

  According to such a monitoring system according to the first embodiment, monitoring information can be used flexibly. For example, as a result of the monitoring server 200 storing the monitoring information in a predetermined storage unit, monitoring images other than real time can be acquired, and the monitoring information can be used flexibly. Moreover, according to the monitoring system according to the first embodiment, as a result of the monitoring server 200 storing the monitoring information in a predetermined storage unit, even if the monitoring sensor 100 is taken out, the stored monitoring information can be acquired. Monitoring information can be used flexibly.

  Further, for example, a method of providing a monitoring sensor and a server at home can be considered. Specifically, information to be notified to the user terminal is preset in the server. Further, the server notifies the user terminal when the information received from the monitoring sensor matches information to be notified that is set in advance. In addition, the server transmits information from the monitoring sensor when a request is met from the user terminal. However, in this case, in order to operate the server at home, the hurdles are high, such as the need for capital investment such as 24-hour energization and UPS (Uninterruptible Power Supply). For example, even if the monitoring sensor and the server are provided at home, it is meaningless to provide the monitoring sensor and the server at home if the server itself is stolen due to an empty nest. In this regard, according to the monitoring system according to the first embodiment, for example, by using the monitoring server 100 provided by the service provider, the problem of the technique of providing the monitoring sensor and the server at home can be solved. .

  Also, for example, some small computers and monitoring sensors 100 currently have network connectivity. According to the monitoring system according to the first embodiment, for example, by providing the monitoring server 100 provided by the service provider, it is possible to easily and effectively use a small computer or monitoring sensor 100 having network connectivity. is there.

[Configuration of monitoring system]
An example of the configuration of the monitoring system according to the first embodiment will be described with reference to FIG. FIG. 2 is a block diagram illustrating an example of the configuration of the monitoring system according to the first embodiment. In the example illustrated in FIG. 2, the monitoring system includes a monitoring sensor 100, a monitoring server 200, and a user terminal 300.

  The monitoring sensor 100 is connected to the monitoring server 200 via a network. For example, the monitoring sensor 100 is connected via an arbitrary network such as the Internet or an intranet. The monitoring sensor 100 may be any general sensor, for example, a monitoring camera, a human sensor, a door phone, or the like. In the following description, a case where the monitoring sensor 100 belongs to a user and a plurality of users do not share the same monitoring sensor 100 will be described.

  In the example illustrated in FIG. 2, the monitoring sensor 100 includes a sensor side transmission control unit 110. When the monitoring sensor 100 acquires monitoring information, the sensor-side transmission control unit 110 transmits authentication information used for authentication of the monitoring sensor 100 by the monitoring server 200 to the monitoring server 200. The sensor-side transmission control unit 110 transmits authentication information such as a user name and a password using a technique that is difficult to eavesdrop such as CHAP (Challenge Handshake Authentication Protocol). The sensor-side transmission control unit 110 encrypts the communication path using, for example, SSL (Secure Socket Layer) or ssh (Secure SHell), and then transmits the authentication information using plain text or CHAP. . Note that the above-described authentication information transmission method by the sensor-side transmission control unit 110 is an example, and the present invention is not limited to this. For example, the sensor-side transmission control unit 110 may use an electronic signature, may use a VPN (Virtual Private Network), or may use any method.

  Upon receiving an authentication confirmation that is information indicating that the authentication process by the monitoring server 200 has been successful, the sensor-side transmission control unit 110 transmits identification information and monitoring information associated with the user of the monitoring sensor 100 to the monitoring server 200. To do. For example, as the monitoring information, the sensor-side transmission control unit 110 transmits a monitoring image every time a monitoring image is captured, transmits monitoring information indicating that the detection is performed every time a person is detected, and each time a doorphone is pressed. Monitoring information indicating that the button has been pressed is transmitted. For example, the sensor side transmission control part 110 transmits the user name allocated to the monitoring sensor 100 as identification information. The identification information is assigned in advance to the monitoring sensor 100, for example.

  Below, for convenience of explanation, a case where the sensor-side transmission control unit 110 uses a user name as identification information will be described as an example. However, the present invention is not limited to this, and arbitrary identification information is transmitted. good. For example, the sensor-side transmission control unit 110 may transmit an IP (Internet Protocol) address or a combination of an IP address and a user name. For example, when using an IP address as identification information, the monitoring server 200 has a table that associates an IP address with a user, and a user associated with the monitoring sensor 100 based on the association stored in the table. Identify

  An example will be described in which the monitoring sensor 100 to which the identification information “user 001” is assigned has taken a monitoring image at “2010/8/12 17:02”. In this case, when the sensor-side transmission control unit 110 acquires the monitoring image, the monitoring server 200 transmits the monitoring image acquisition time “2010/8/12 17:02”, the monitoring image, and the identification information “user 001”. Send to.

  The monitoring server 200 is connected to the monitoring server 200 and the user terminal 300 via a network. The monitoring server 200 is a server that receives monitoring information obtained by the monitoring sensor 100. The monitoring server 200 has a function as a Web server using, for example, Apache or IIS (Internet Information Server), and has a function as an E-mail server using sendmail, postfix, exim, or the like. For example, the monitoring server 200 searches for monitoring information by the user terminal 300 using the function as a Web server, and receives the monitoring information from the monitoring sensor 100. Note that the monitoring server 200 may receive the monitoring information using ftp (File Transfer Protocol) or ssh. In addition, the monitoring server 200 transmits monitoring information to the user terminal 300 using a function as an E-mail server, for example.

  In the example illustrated in FIG. 2, the monitoring server 200 includes a monitoring information DB 211, a specific condition DB 212, and a monitoring server control unit 220. The monitoring information DB 211 is connected to the monitoring server control unit 220. The monitoring information DB 211 stores data used for various processes performed by the monitoring server control unit 220. The monitoring information DB 211 corresponds to, for example, a semiconductor memory device such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk. In the monitoring information DB 211, monitoring information is stored by the monitoring server control unit 220, and the monitoring information is read by the monitoring server control unit 220 and transmitted to the user terminal 300.

  The monitoring information DB 211 stores identification information and monitoring information in association with each other. FIG. 3 is a diagram illustrating an example of information stored in the monitoring information DB according to the first embodiment. In the example illustrated in FIG. 3, the monitoring information DB 211 stores identification information, monitoring information, and time in association with each other. Hereinafter, the case where the time indicates the time when the monitoring information is acquired by the monitoring sensor 100 will be described. However, the present invention is not limited to this. For example, the time may indicate the time when the monitoring server 200 receives the monitoring information and the identification information, may indicate the time when the monitoring information and the identification information are transmitted by the monitoring sensor 100, and may be an arbitrary time. May be used.

  In the example shown in FIG. 3, the monitoring information DB 211 stores the time. However, the present invention is not limited to this, and the time may not be stored. Further, for example, when the time is not transmitted from the monitoring sensor 100, the time when the monitoring server 200 receives the monitoring information and the identification information, or the monitoring information and the identification information are received by the monitoring sensor 100. The transmitted time may be stored as the time.

  In the example illustrated in FIG. 3, the monitoring information DB 211 stores identification information “user 001”, monitoring information “doorphone pressing detection”, and time “2010/8/12 17:00” in association with each other. In other words, the monitoring information DB 211 stores that the monitoring sensor 100 of the user 001 detects that the door phone is pressed at “2010/8/12 17:00”. In the example illustrated in FIG. 3, the monitoring information “person detection” indicates that the person sensor has detected a person, and the monitoring information “monitoring image” indicates a monitoring image captured by the monitoring camera.

  As shown in FIG. 3, the monitoring information DB 211 stores monitoring information obtained by the monitoring sensors 100 of a plurality of users. For example, in the example illustrated in FIG. 3, the monitoring information DB 211 stores monitoring information for the user 001, stores monitoring information for the user 002, and stores monitoring information for other users.

  The specific condition DB 212 is connected to the monitoring server control unit 220. The specific condition DB 212 stores data used for various processes by the monitoring server control unit 220. The specific condition DB 212 corresponds to, for example, a semiconductor memory device such as a RAM, a ROM (Read Only Memory), or a flash memory, or a storage device such as a hard disk or an optical disk. The specific condition DB 212 is also referred to as a “specific condition storage unit”. In the specific condition DB 212, specific conditions are stored in advance, and the specific conditions are used by the monitoring server control unit 220.

  The specific condition DB 212 stores specific conditions for specifying predetermined monitoring information to be transmitted to the user terminal 300 used by the user associated with the identification information in association with the identification information. FIG. 4 is a diagram illustrating an example of information stored in the specific condition DB according to the first embodiment. In the example illustrated in FIG. 4, the specific condition DB 212 stores “identification information”, “specific condition”, and “transmission destination identification information” in association with each other. The transmission destination identification information is identification information for identifying the user terminal 300 as the transmission destination, and is identification information for identifying the user terminal 300 used by the user associated with the identification information.

  In the example illustrated in FIG. 4, the specific condition DB 212 stores the identification information “user 001”, the specific condition “monitoring image where a person is photographed”, and the transmission destination identification information “xxxxxxx@xxxxxx.co.jp” in association with each other. To do. That is, the specific condition DB 212 stores that the monitoring image in which a person is photographed among the monitoring information associated with the identification information “user 001” is transmitted to “xxxxxxx@xxxxxx.co.jp”.

  The specific condition “person detection” in FIG. 4 indicates a specific condition for specifying monitoring information indicating that the interpersonal sensor has detected a person. The specific condition “all” indicates a specific condition for specifying all the monitoring information. That is, the example shown in FIG. 4 indicates that all the monitoring information of the user 001 is transmitted to the device at “192.168.0.1”.

  In FIG. 4, when the transmission destination identification information is a telephone number, for example, the monitoring information is transmitted by voice, and when the transmission destination identification information is a mail address, for example, the monitoring information is sent to the mail. To send. Note that the specific condition shown in FIG. 4 is an example, and the present invention is not limited to this, and any specific condition may be used. For example, a plurality of conditions may be combined and used as the specific condition. Also good. For example, specifying the condition that there is both a condition that the user is often absent and a condition that there are both monitoring information indicating that a person has been detected by the interpersonal sensor and a monitoring image in which the person is photographed. It is good as a condition.

  The monitoring server control unit 220 has an internal memory that stores a program that defines various processing procedures and the like, and controls various processes. The monitoring server control unit 220 is an electronic circuit such as an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a central processing unit (CPU), or a micro processing unit (MPU). In the example illustrated in FIG. 2, the monitoring server control unit 220 includes a storage unit 221 and a server-side transmission control unit 222.

  When receiving the authentication information from the monitoring sensor 100, the storage unit 221 executes an authentication process. Note that the authentication processing by the storage unit 221 may use arbitrary authentication processing, and a description thereof is omitted. Here, when the authentication is successful, the storage unit 221 transmits an authentication confirmation to the monitoring sensor 100. On the other hand, when the authentication fails, the storage unit 221 terminates the process without transmitting.

  When the storage unit 221 receives the identification information and the monitoring information transmitted by the sensor-side transmission control unit 110 of the monitoring sensor 100 that has been successfully authenticated, the storage unit 221 stores the received identification information and the monitoring information in association with each other in the monitoring information DB 211. To do. For example, when receiving the monitoring image, the time “2010/8/12 17:02” and the identification information “user 001” from the monitoring sensor 100, the storage unit 221 stores the received monitoring image as monitoring information in the monitoring information DB 211. The time and identification information are stored in the monitoring information DB 211 in association with the monitoring information.

  The server-side transmission control unit 222 transmits predetermined monitoring information among the monitoring information stored in the storage unit 221 to the user terminal 300 of the user associated with the identification information associated with the monitoring information. Specifically, the server-side transmission control unit 222 identifies the monitoring information specified by the specific condition stored in the specific condition DB 212 among the monitoring information stored by the storage unit 221 in association with the specific condition. It transmits to the user terminal 300 linked | related with information.

  For example, when the monitoring information is stored in the storage unit 221, the server-side transmission control unit 222 reads the specific condition from the specific condition DB 212 using the identification information associated with the stored monitoring information as a search key. Here, if the server-side transmission control unit 222 determines that the read specific condition matches the monitoring information, the server-side transmission control unit 222 reads the transmission destination identification information associated with the specific condition determined to match, and reads the read destination identification The monitoring information is transmitted to the user terminal 300 identified by the information.

  For example, the case where the identification information “user 001” and the monitoring information “monitoring image” are stored in the monitoring information DB 211 will be described. In this case, the server-side transmission control unit 222 reads from the specific condition DB 212 the specific conditions “monitoring image in which a person is photographed”, “human detection”, and “all” associated with the identification information “user 001”. Then, the server-side transmission control unit 222 determines whether a person is included in the monitoring image stored in the monitoring information DB 211 by executing an arbitrary image identification process. Read the recipient identification information “xxxxxxx@xxxxxx.co.jp” associated with the “monitoring image where the person was photographed” and set the destination email address to “xxxxxxx@xxxxxx.co.jp” and monitor information “monitoring image” Send. The server-side transmission control unit 222 ends the process regarding the specific condition “person detection” because the monitoring information is “monitoring image” and is not monitoring information about the human sensor, and thus does not match the specific condition. Further, the server-side transmission control unit 222 reads the destination identification information “192.168.0.1” associated with the specific condition “all” because the specific condition “all” matches the specific condition. The monitoring information “monitoring image” is transmitted to the user terminal 300 identified by “0.1”.

  Specifically, when the server-side transmission control unit 222 receives request information for requesting monitoring information from the user terminal 300, the server-side transmission control unit 222 requests the monitoring information associated with the identification information associated with the user terminal 300. The monitoring information requested by the information is acquired from the monitoring information DB 211, and the acquired monitoring information is transmitted to the user terminal 300 as predetermined information. The request information includes, for example, a condition for specifying monitoring information that the user requests to acquire. To explain with a more detailed example, the request information includes a time condition, a condition for specifying the type of monitoring information, and the like. However, the present invention is not limited to this, and arbitrary information may be used as the request information.

  More specifically, when receiving the authentication information from the user terminal 300, the server-side transmission control unit 222 authenticates the user terminal 300 by executing an arbitrary authentication process. It transmits to the terminal 300. Thereafter, when the server side transmission control unit 222 receives the identification information and the request information from the user terminal 300, the monitoring information associated with the identification information received from the user terminal 300 among the monitoring information stored in the monitoring information DB 211. The search information is acquired from the monitoring information DB 211 by searching the monitoring information requested by the request information. Then, the server-side transmission control unit 222 transmits the monitoring information obtained as a result of the search to the user terminal 300.

  For example, the server-side transmission control unit 222 executes authentication processing using a combination of a user name and a password, an electronic signature, a terminal unique number, or the like. However, the authentication method by the server side transmission control part 222 mentioned above is an example, and is not limited to this, For example, VPN may be used and arbitrary methods may be used. In addition, the monitoring server 200 may be realized by, for example, mounting each function corresponding to each unit illustrated in FIG. 2 on an arbitrary information processing apparatus such as a known personal computer or workstation.

  The user terminal 300 is connected to the monitoring server 200 via a network. The user terminal 300 corresponds to a mobile communication terminal such as a personal computer, a home game machine, a PDA (Personal Digital Assistant), a mobile phone, or a PHS (Personal Handy-phone System). The user terminal 300 outputs the monitoring information received from the monitoring server 200 to the user from a display or a speaker. In addition, when the request information is input by the user, the user terminal 300 transmits the authentication information to the monitoring server 200, and then receives the authentication confirmation and transmits the request information to the monitoring server 200.

[Flow of monitoring information storage processing]
An example of the flow of monitoring information storage processing in the monitoring system according to the first embodiment will be described with reference to FIG. FIG. 5 is a sequence diagram illustrating an example of a flow of monitoring information storage processing in the monitoring system according to the first embodiment. Hereinafter, a case where the monitoring sensor 100 to which the identification information “user 001” is assigned has taken a monitoring image at “2010/8/12 17:02” will be described as an example.

  As shown in FIG. 5, in the monitoring sensor 100, when monitoring information is acquired (Yes at Step S101), the sensor-side transmission control unit 110 transmits authentication information to the monitoring server 200 (Step S102). For example, when acquiring the monitoring information, the sensor-side transmission control unit 110 transmits authentication information such as a user name and a password using CHAP.

  In the monitoring server 200, when the storage unit 221 receives the authentication information from the monitoring sensor 100, the storage unit 221 executes an authentication process (step S103). Then, when the authentication is successful (Yes at Step S104), the storage unit 221 transmits an authentication confirmation that is information indicating that the authentication processing is successful to the monitoring sensor 100 (Step S105). On the other hand, when the authentication has failed (No at Step S104), the storage unit 221 ends the process as it is.

  Thereafter, in the monitoring sensor 100 that has received the authentication confirmation, the sensor-side transmission control unit 110 transmits the monitoring information (step S106). Specifically, the sensor-side transmission control unit 110 transmits identification information and monitoring information associated with the user of the monitoring sensor 100 to the monitoring server 200. For example, when the sensor-side transmission control unit 110 acquires the monitoring image, the monitoring server 200 receives the monitoring image acquisition time “2010/8/12 17:02”, the monitoring image, and the identification information “user 001”. Send.

  Then, in the monitoring server 200 that has received the monitoring information, the storage unit 221 stores the monitoring information in the monitoring information DB 211 (step S107). Specifically, the storage unit 221 stores the received identification information and monitoring information in the monitoring information DB 211 in association with each other. For example, when receiving the monitoring image, the time “2010/8/12 17:02” and the identification information “user 001” from the monitoring sensor 100, the storage unit 221 stores the received monitoring image as monitoring information in the monitoring information DB 211. The time and identification information are stored in the monitoring information DB 211 in association with the monitoring information.

  In the monitoring server 200, the server-side transmission control unit 222 determines whether or not the monitoring information is a target of notification to the user terminal 300 (step S108), and determines that the information is a target of notification (Yes in step S108). The monitoring information is transmitted to the user terminal 300 (step S109). That is, the server-side transmission control unit 222 transmits the specific condition “monitoring image where a person is photographed” associated with the identification information “user 001” from the specific condition DB 212. If the monitoring image contains a person, the recipient identification information “xxxxxxx@xxxxxx.co.jp” associated with the specific condition “monitoring image where a person was photographed” is read and the recipient email The monitoring information “monitoring image” is transmitted with the address “xxxxxxx@xxxxxx.co.jp”. On the other hand, if the server-side transmission control unit 222 determines that the information is not a notification target (No at Step S108), for example, if no person is included in the monitoring image, the process ends without transmitting the monitoring image.

[Processing when request information is sent]
Next, an example of processing when request information is transmitted in the monitoring system according to the first embodiment will be described with reference to FIG. FIG. 6 is a sequence diagram illustrating an example of processing when request information is transmitted in the monitoring system according to the first embodiment.

  As shown in FIG. 6, in the user terminal 300, when request information is input by the user (Yes at Step S201), the user terminal 300 transmits authentication information to the monitoring server 200 (Step S202). For example, the user terminal 300 transmits a combination of a user name and a password as authentication information.

  Then, in the monitoring server 200 that has received the authentication information, the server-side transmission control unit 222 executes an authentication process (step S203). When the authentication is successful (Yes at Step S204), an authentication confirmation is transmitted to the user terminal 300 (Step S205). On the other hand, if the authentication fails (No at Step S204), the process is terminated as it is.

  Thereafter, the user terminal 300 that has received the authentication confirmation transmits the request information input by the user to the monitoring server 200 (step S206). For example, the user terminal 300 transmits, as the request information, a time condition, a condition for specifying the type of monitoring information, and the like.

  In the monitoring server 200, the server-side transmission control unit 222 sets the monitoring information associated with the identification information received from the user terminal 300 among the monitoring information stored in the monitoring information DB 211 as a search target. The monitoring information is acquired by searching the monitoring information requested by the request information (step S207). Then, the server-side transmission control unit 222 transmits the monitoring information obtained as a result of the search to the user terminal 300 (Step S208).

[Effect of Example 1]
As described above, according to the first embodiment, the monitoring sensor 100 transmits identification information and monitoring information to the monitoring server 200. In addition, the monitoring server 200 has a monitoring information DB 211, and when the identification information and the monitoring information transmitted by the monitoring sensor 100 are received, the received identification information and the monitoring information are associated with each other and stored in the monitoring information DB 211. Then, the monitoring server 200 transmits predetermined monitoring information among the stored monitoring information to the user terminal 300 associated with the identification information associated with the monitoring information. As a result, the monitoring information can be used flexibly.

  Although the embodiments of the present invention have been described so far, the present invention may be implemented in other embodiments besides the above-described embodiments. Therefore, other embodiments will be described below.

[Monitoring information storage timing]
For example, in the above-described embodiment, the monitoring server 200 stores the monitoring information in the monitoring information DB 211 and transmits the monitoring information to the user terminal 300 every time the monitoring information is received. However, the present invention is not limited to this. Absent. For example, when the monitoring server 200 receives a certain amount of monitoring information, the monitoring information may be stored together in the monitoring information DB 211 or may be stored at an arbitrary timing. In addition, for example, the monitoring server 200 may execute a process of periodically transmitting monitoring information to the user terminal 300, or may transmit at an arbitrary timing.

[Privacy preservation of monitoring information]
For example, the privacy of the monitoring information may be preserved. For example, the privacy of the monitoring information may be preserved by making the monitoring server 200 execute access control so that each user cannot access the monitoring information of other users. As a result, it is possible to easily realize privacy preservation of monitoring information.

  Further, for example, the storage unit 221 of the monitoring server 200 may encrypt the monitoring information and store it in the monitoring information DB 211 using an encryption key set for each user. Further, for example, the server-side transmission control unit 222 of the monitoring server 200 may encrypt the monitoring information using an encryption key set for each user and then transmit the encrypted information to the monitoring sensor. In this case, it is possible to cope with wiretapping. Also, for example, even if the line is encrypted using VPN or the like, and the storage unit 221 or the server-side transmission control unit 222 of the monitoring server 200 encrypts the monitoring information using an encryption key set for each user. good.

[Monitoring information transmission method]
Further, for example, in the above-described embodiment, the monitoring server 200 transmits the monitoring information specified by the specific condition to the user terminal 300 and transmits the monitoring information to the user terminal 200 according to the request information from the user terminal 200. Indicated. However, the present invention is not limited to this, and the monitoring server 200 displays the monitoring information specified by the specific condition in the user terminal 300, while the monitoring server 200 transmits the monitoring information according to the request information from the user terminal 200. You do not have to send to. Similarly, for example, the monitoring server 200 may not transmit the monitoring information specified by the specific condition to the user terminal 300, but may transmit the monitoring information to the user terminal 200 according to the request information from the user terminal 200. Moreover, the monitoring server 200 may transmit the monitoring information to the user terminal 300 at an arbitrary timing or trigger.

[Door phone]
Further, for example, when a door phone that stores an image of a visitor at the time of absence is used as the monitoring sensor 100, an image of the visitor at the time of absence may be stored in the monitoring server 200.

[Operation of home appliances when absent]
In addition, for example, when a home appliance is used as the monitoring sensor 100, the monitoring server 200 may transmit information indicating an abnormal situation to the user terminal 300 when the home appliance is operating in the absence. That is, the monitoring server 200 has an absence information table that stores, for each user, absence information indicating whether or not the user is absent. Then, when the monitoring server 200 receives monitoring information indicating that the home appliance has been operated from the monitoring sensor 100 as the home appliance when the user is absent, the monitoring server 200 transmits to the user terminal 300 that the abnormal situation has occurred. .

  For example, when the monitoring server 200 receives the information indicating the absence such as an arbitrary password and the identification information from the user terminal 300, the monitoring server 200 updates the absence information of the user identified by the received identification information to the information indicating the absence. Similarly, when information indicating that an arbitrary password is not absent and identification information are received from the user terminal 300, the absence information of the user identified by the received identification information is updated to information indicating absence. .

  In addition, for example, a notification device for notifying the monitoring server 200 of whether or not it is present may be provided, and the monitoring server 200 may update the absence information table based on information transmitted by the device. For example, the case where a door is used as a notification device will be described as an example. In this case, the door as the notification device transmits information indicating the absence to the monitoring server 200 when the door is locked from the outside, and displays the information indicating the absence when the door is unlocked. 200. In addition, for example, when there is a response to the person sensor when absent, the gate lamp may be turned on to dispose of the person at home, and the auxiliary lamp of the surveillance camera may be turned on.

[Fault detection]
For example, the monitoring server 200 may transmit information about the monitoring sensor 100 that has not transmitted the monitoring information for a predetermined period to the user terminal 300. If the monitoring information is not transmitted for a predetermined period, the monitoring sensor 100 may be broken or destroyed. Based on this, the monitoring server 200 stores the reception time at which the monitoring information is received in association with each ID for identifying the monitoring sensor 100, and stores the ID of the monitoring sensor 100 that has not received the monitoring information for a predetermined period. May be transmitted to the user terminal 300.

  For example, for the monitoring sensor 100 that periodically transmits monitoring information, the monitoring server 200 transmits the ID of the monitoring sensor 100 to the user terminal 300 when the monitoring information is not transmitted a predetermined number of times. Further, for example, for the monitoring sensors 100 other than the monitoring sensor 100 that periodically transmits the monitoring information, the monitoring server 200 sets a predetermined period for each monitoring sensor 100, and even if the set predetermined period has passed. When the monitoring information is not transmitted, the ID of the monitoring sensor 100 is transmitted to the user terminal 300.
