Description

  The present invention relates to a security system that detects intrusion of a suspicious person into a garden of a house and checks detection information by a resident at home or an external monitoring center.

  Conventionally, a security system has been provided in which various sensors are arranged in a monitored building such as a detached house, an intruder into the building is detected, and an abnormality is reported to a monitoring center or the like. There has also been proposed a monitoring system that monitors a garden of a building with a sensor, detects an intruder outdoors before entering the building, and alerts early.

  For example, Patent Document 1 discloses a constant security system that transmits alarm information indicating that an abnormality has been detected to a monitoring center connected to the Internet when an abnormality in a detached garden is detected. In this system, when the crime prevention mode is set, the presence of a person is monitored by a human sensor installed at the entrance of the garden. When the stay of the human body is detected over a predetermined time, alarm information indicating that an abnormality has been detected is output. Also, the video data captured by the monitoring camera is output to the indoor monitor and the monitoring center monitor.

JP 2008-146401 A

  In the grounds of buildings such as single-family gardens, visitors such as visitors and delivery companies other than suspicious individuals enter and exit. If the security system detects these persons and reports them uniformly to the monitoring center, unnecessary notifications increase, resulting in an increase in security costs. Therefore, if the entrance area, such as the entrance, where there is a possibility of entry / exit from a suspicious person, is distinguished from other monitoring areas, and an entry into the entrance area is detected, the user of the security system once uses an indoor monitor. It is conceivable to notify the monitoring center as necessary after confirming the image.

However, it is not always possible for the user to check the presence or absence of an abnormality with an image or the like and determine whether or not a report is necessary. For example, there is a case where only a young child can be supported. In such a case, if the user reports the abnormality to the monitoring center etc., the notification to the monitoring center may not be made or delayed even though the suspicious person has entered the entrance area. There is a risk that the damage will spread.
Accordingly, an object of the present invention is to provide a security system that can appropriately set a monitoring area according to a user's situation when entry into a monitoring area is detected.

  In order to achieve the above object, the security system of the present invention is a security system in which a person who has entered a monitoring area consisting of at least a regular monitoring area and a semi-monitoring area set on the outer periphery of the building is detected and determined abnormally. A detection unit for detecting an invading person, an identification unit for identifying whether the person is the user, a storage unit for storing attributes of the user residing in a building, and the normal monitoring area A monitoring control unit that determines an abnormality when an intrusion other than a user is detected and determines an abnormality with a predetermined delay when an intrusion other than a user into the semi-monitoring area is detected, and is used in a building A monitoring control unit configured to perform abnormality determination by setting the semi-monitoring area as the regular monitoring area when the attribute of the person satisfies a predetermined condition.

  According to such a configuration, in normal times, when a semi-monitoring area where a person other than a suspicious person can come and go is distinguished from a regular monitoring area and the monitoring standard is set loosely, and a specific user is present in the building Therefore, the monitoring standard in the semi-monitoring area can be made as strict as the regular monitoring area, and appropriate monitoring processing can be executed according to the user's attribute. User attribute is an indicator that confirms whether or not an intruder is a suspicious person based on the contents of notification and the situation at the site, and directly or indirectly indicates whether or not notification is necessary and can be performed. It is. In other words, when a user with the ability to confirm a suspicious person is present, unnecessary notifications are suppressed by reporting to the monitoring center after confirmation of the user, and a user without confirmation ability (for example, When a child is resident, the monitoring standard can be set strictly even in the semi-monitoring area, and the safety of the resident user can be ensured. As described above, by variably setting the monitoring area according to the resident attribute and executing the monitoring process, it is possible to realize a security system that is highly convenient and highly safe.

Further, in the above configuration, the information processing apparatus further includes a notification terminal having a display unit for notifying detection information to a user in the building and an operation unit for inputting an emergency operation, and the monitoring control unit is configured for the user to the semi-monitoring area. When an intrusion other than the above is detected, if there is a resident user and the attribute of the user does not satisfy a predetermined condition, the detection information is transmitted to the notification terminal and the emergency operation is received. The abnormality is determined.
According to such a configuration, when the attribute of the resident user does not satisfy the predetermined condition (for example, there is an adult), an abnormality determination is performed after confirming the user with respect to the act of entering the semi-monitoring area. Therefore, it is possible to prevent unnecessary abnormality reports from being made by user confirmation.

In the above configuration, when the monitoring control unit detects an intrusion other than a user into the semi-monitoring area, if the resident user does not exist, detection of the intruding person continues for a predetermined time. Therefore, the abnormality is determined.
According to such a configuration, when the user is absent, an abnormality is determined by the stay of an intruder in the semi-monitoring area, and therefore, for the purpose of picking and the like while preventing an erroneous abnormality determination by a courier or the like A suspicious person's intrusion can be determined abnormally.

In the above configuration, the storage unit stores presence / absence information that is updated in response to the user's entry / exit, and the monitoring control unit enters the building from outside the user's premises through a monitoring area. When the movement of the user is detected, it is determined to enter, and when the movement of the user from the building through the monitoring area to the outside of the site is detected, it is determined to leave, and the presence / absence information is updated.
According to this configuration, it is possible to manage whether or not the user is resident using the person detection information and the user identification information. In addition, since the presence / absence information of the user can be managed without requiring any special operation by the user, a highly convenient security system can be realized.

  In the security system having the above-described configuration, the sensor terminal is further provided with an imaging unit that captures an image of a monitoring area and acquires an image, and the monitoring control unit transmits the detection information including an image acquired by the imaging unit to the notification terminal. It is also preferable to transmit to the monitoring center.

  Further, in the security system having the above configuration, the sensor terminal further includes a voice output unit that outputs the voice received from the monitoring center to the monitoring area, and a voice input unit that collects sound in the monitoring area. It is also preferable to be able to form a voice call with the notification terminal or the monitoring center.

  ADVANTAGE OF THE INVENTION According to this invention, a monitoring area can be set appropriately according to the user who lives, and a monitoring process can be performed, and the security system which has convenience and safety | security can be provided.

It is the figure which showed typically the operation image of the security system of this embodiment. It is a functional block diagram which shows schematic structure of a sensor terminal. It is a figure which shows an example of user management information. It is a flowchart which shows the monitoring process at the time of a human body detection. It is a flowchart which shows the monitoring process at the time of a human body detection.

  Hereinafter, a preferred embodiment of a security system according to the present invention will be described in detail with reference to the drawings, taking as an example a security system that targets a detached dwelling unit and detects an intruder into a dwelling yard.

First, the configuration and operation of the security system of this embodiment will be schematically described. FIG. 1 is a diagram schematically showing an operation image of the security system according to the present embodiment.
The security system uses the site (garden part) on the outer periphery of the building as the monitoring area 3, and notifies the sensor terminal 1 that monitors intrusion from outside the site and the users in the house of the occurrence of intruders in the garden part. It is comprised including the alerting | reporting terminal 2 to perform. A plurality of sensor terminals 1 are arranged at appropriate outdoor locations so as to cover the garden part which is the monitoring area 3. Further, in the monitoring area 3, an area in which a delivery agent or a visitor may go in and out is set as a semi-monitoring area 5, and an area in which only a normal user does not enter is monitored as a normal monitoring area 4. The semi-monitoring area 5 is set, for example, at a place that passes when moving from outside the site to the entrance, or a place where a meter meter or the like enters. The notification terminal 2 is provided in any place in the house, for example, in the living room. Two or more notification terminals 2 may be provided, and may be a portable terminal that can be carried instead of fixed installation.

When the sensor terminal 1 detects an intrusion into the regular monitoring area 4, the sensor terminal 1 determines that an intrusion has occurred by the suspicious person and makes an abnormality determination, and notifies the external monitoring center via the communication network. At this time, the current photographed image and sound are transmitted in real time, and the situation at the site where the abnormality occurs can be grasped at the monitoring center.
When an intrusion into the semi-monitoring area 5 is detected, the photographed image at the time of detection is transmitted to the notification terminal 2 together with the detection information in order for the user to confirm whether or not he / she is a suspicious person. The notification terminal 2 that has received the detection information and the image notifies the user at home that an intruder has occurred and displays the received image to prompt the user to confirm. The user checks the displayed image, and performs a notification operation when it is confirmed that the person who entered the site is a suspicious person. When the sensor terminal 1 detects the user's notification operation via the notification terminal 2, the sensor terminal 1 notifies the monitoring center of the abnormality. At this time, the image at the time of detection is transmitted, and the current captured image and sound are transmitted in real time. When there is no user at home, a report operation is performed to the monitoring center without requiring a report operation by the user. At the monitoring center that has received the abnormal report, the controller will respond to the intruder while checking the image and sound, warn to stop the crime through the sensor terminal 1, and to the guards and police who are waiting nearby Request a response, grasp the on-site situation, and take a prompt and appropriate response.

  Even if the user is at home, there is a possibility that the intrusion notification at the notification terminal 2 cannot be appropriately handled when the home user is a user with low judgment ability such as a young child. In other words, even if the image is confirmed, it may be impossible to correctly determine whether or not the person is a suspicious person, or the abnormality reporting operation itself may not be recognized. Therefore, in this security system, confirmation authority information consisting of attributes such as the user's age is managed. When only non-authorized persons are at home, the semi-monitoring area 5 is treated in the same manner as the regular monitoring area 4, and the semi-monitoring area is treated. Even when an intrusion is detected, an abnormality report is sent to the monitoring center without requiring a user's reporting operation, and the situation can be checked quickly and appropriately by the monitoring center.

Hereinafter, a specific structure and operation | movement are demonstrated about the security system of this embodiment.
In addition to the sensor terminal 1 and the notification terminal 2 described above, the security system further includes a wireless tag possessed by the user and capable of identifying that the user is a resident (or a qualified person). The security system identifies whether or not the person entering the monitoring area 3 is a user by the wireless tag. Further, based on the entrance / exit of the user who owns the wireless tag, the user's home status and the attributes of the user at home are managed.

The wireless tag corresponds to a so-called RFID system responder, and when a query wave having a predetermined frequency is received, a response wave with its own identification code is transmitted.
The notification terminal 2 includes a wireless communication unit for wireless communication with the sensor terminal 1, a display unit for displaying images and sounds received from the sensor terminal 1, an operation unit for inputting a user's notification operation, And a notification control unit that controls each unit. The wireless communication unit is means for wirelessly communicating with the notification terminal 2 and other sensor terminals 1. For example, a short-range wireless communication standard such as Bluetooth (registered trademark) or a wireless LAN standard represented by IEEE 802.11 can be used. The display unit includes a liquid crystal display and a speaker. The operation unit is realized by a button switch or an operation button displayed on the screen when the display unit is a touch panel display. The notification terminal 2 may be configured as a terminal dedicated to the security system, but may be configured integrally with the function of the interphone master so that it can be used in combination with a general interphone master.

FIG. 2 is a functional block diagram illustrating a schematic configuration of the sensor terminal 1.
The sensor terminal 1 includes a sensor 100, a tag reader 102, a camera 104, a microphone 106, a speaker 108, a home wireless communication unit 110, a public wireless communication unit 112, a battery 114, a storage unit 116, and a monitoring control unit.

  The sensor 100 detects a human body that has entered the monitoring area 3. For example, the scanning area 3 is configured by a laser distance measuring sensor that executes laser scanning at a predetermined cycle and can specify the presence and position of a human body according to the magnitude, angle, and distance of the change in distance. The sensor 100 is not limited to the laser distance measuring sensor, and various sensors capable of detecting the human body and its position, such as a microwave sensor that detects a change in the reflected wave of the microwave and an image sensor that detects an image change, are applied. Is possible.

  The tag reader 102 detects a wireless tag possessed by the user in the detection area. It corresponds to an interrogator of a so-called RFID system, transmits an interrogation wave to a detection area, receives a response wave from the radio tag, and reads an identification code given to the radio tag. The tag reader 102 may be driven constantly or periodically, and may be driven at a timing based on an instruction from the control unit. Here, the security system uses the detection information of the sensor 100 and the detection information of the tag reader 102 to determine whether the person entering the monitoring area 3 is a user. The detection area is set to be approximately the same.

The camera 104 acquires an image or video at a predetermined frame rate with the range including the monitoring area 3 of the sensor 100 as an imaging angle of view.
The microphone 106 is means for collecting sound generated in the monitoring area 3.
The speaker 108 is a means for generating a warning sound or sound for the monitoring area 3. Based on the control of the monitoring control unit, a warning sound such as a buzzer or warning guidance for an intruder or a voice received from the monitoring center is output.

The in-home wireless communication unit 110 is means for wirelessly communicating with the notification terminal 2 and other sensor terminals 1. For example, it comprises a communication module that complies with a short-range wireless communication standard such as Bluetooth (registered trademark) or a wireless LAN standard typified by IEEE 802.11.
The public wireless communication unit 112 is means for performing wireless communication with an external monitoring center via a public network. It is desirable that an image can be transmitted to the monitoring center in real time, and for example, a communication module conforming to a high-speed wireless communication standard represented by Wimax (registered trademark) or XGP (registered trademark) is used.
The battery 114 is means for supplying operating power to the monitoring control unit. A commercial power source may be used as the power supply means, or the commercial power source and the battery 114 may be used in combination.

The storage unit 116 stores various programs for operating the sensor terminal 1 and stores user management information, accumulated images, and area map information in an updatable manner. FIG. 3 shows an example of user management information.
The user management information includes the identification code of the wireless tag possessed by the user, the user's attributes, that is, the confirmation authority information indicating the presence or absence of confirmation authority for determining whether or not the person is a suspicious person, presence / absence indicating whether the user is at home or going out It is data in which information is associated with each other, and is updated as needed by the monitoring control unit. Here, the presence / absence of the confirmation authority is directly set as the user's attribute. However, the present invention is not limited to this, and the confirmation authority may be separated at a predetermined age by associating the age as the user's attribute. A relationship (father, mother, eldest son, second son, grandfather, etc.) may be associated with each other and confirmation authority may be set separately for the second son and grandfather.

The accumulated image is a data area in which an image captured by the camera 104 can be recorded for a predetermined time, and is recorded and controlled by the monitoring control unit.
The area map information is information representing the positional relationship between the actual layout of the building or garden to be monitored and the monitoring area 3, and the boundary between the monitoring target building and the monitoring area 3, the area outside the site, and the monitoring area 3 The boundary is shown. In addition, the positions of the normal monitoring area 4 and the semi-monitoring area 5 in the monitoring area 3 are stored.

The monitoring control unit is configured by an MPU or the like, and has a function of performing overall control of each unit.
The monitoring control unit detects a human body that has entered the monitoring area 3 based on the detection signal input from the sensor 100 and tracks the movement of the human body. The supervisory control unit refers to the area map information in the storage unit 116 and recognizes that the appearance point of the human body is a human body that has entered from the outside when the appearance point of the human body is on the boundary side with the outside of the site, and the building control unit on the boundary side with the building Recognize that it is a human body that came from within. Conversely, when the tracked human body disappears, if the disappearance point is on the boundary side with the outside of the site, it is recognized as exiting outside, and if it is on the boundary side with the building, it is recognized as entering the building. . Further, the monitoring control unit determines whether the human body belongs to the normal monitoring area 4 or the semi-monitoring area 5 based on the detected position of the human body and the area map information.

  When the monitoring control unit detects the human body, it drives the tag reader 102 to read the wireless tag in the monitoring area 3 and refers to the user management information in the storage unit 116 to determine whether the detected human body is a user. To do. The monitoring control unit updates the user management information based on the presence / absence of the wireless tag and the entrance / exit by moving body tracking. When it is recognized that the user has entered the building, the presence / absence information corresponding to the detected tag identification code is updated to “at home”. When it is recognized that the user has left, the corresponding presence / absence information is updated to “going out”.

  In addition, when the detected human body is not a user but a suspicious person, the monitoring control unit records an input image from the camera 104 as an accumulated image in the storage unit 116 until the human body disappears from the monitoring area. To do.

  In addition, when there is a possibility that the detected human body is a suspicious person, the monitoring control unit refers to the user management information and executes different alarm processing based on the presence / absence information and the confirmation authority information. Further, different alarm processing is executed based on whether the detected human body is in the regular monitoring area 4 or the semi-monitoring area 5.

  When the monitoring control unit detects an intrusion into the regular monitoring area 4, the monitoring control unit is highly likely to be a suspicious person, and prompt action at the monitoring center is required. Therefore, the monitoring control unit is based on reception of a notification operation signal from the notification terminal 2. First, the current image and sound input from the camera 104 and microphone 106 via the public wireless communication unit 112 are transmitted to the monitoring center in real time. When the resident is present, the detection information is transmitted to the notification terminal 2 via the home wireless communication unit 110 to notify the resident of the presence of the intruder.

  When an intrusion into the semi-monitoring area 5 is detected, it cannot be immediately determined whether the person is a suspicious person or a visitor. Therefore, there is a person who is home (there is a user whose presence / absence information is “at home”) and there is a home person with confirmation authority (use of “at home” with confirmation authority information among the “home” users) If there is a person), the input image from the camera 104 and the input sound from the microphone 106 are transmitted to the notification terminal 2 through the home wireless communication unit 110 together with the detection information. Then, when a notification operation signal resulting from the notification operation by the user is received from the notification terminal 2, the current input image and input voice are transmitted to the monitoring center in real time via the public wireless communication unit 112. Further, in response to an instruction command from the monitoring center, the stored image recorded in the storage unit 116 is transmitted to the monitoring center.

  On the other hand, if there is no occupant when the intrusion into the semi-monitoring area 5 is detected (the presence / absence information of all users is “going out”), the stay for a predetermined time in the semi-monitoring area 5 is detected. Then, the current input image and input sound are transmitted to the monitoring center in real time.

  Further, when an intrusion into the semi-monitoring area 5 is detected, there is a resident in the room and there is no resident with confirmation authority (the confirmation authority information of the “at-home” user is all “none”). In this case, since there is only a child and it is necessary to deal directly with the monitoring center, the current input image is received via the public wireless communication unit 112 without receiving the notification operation signal from the notification terminal 2. And the input voice is transmitted to the monitoring center in real time. Since there is a greater danger when only the child is at home than when there is no resident, the monitoring center is immediately notified without making a stay determination.

Next, the flow of processing executed by the monitoring control unit when an intruder appears in the monitoring area 3 will be described with reference to FIGS. 4 and 5.
4 and 5 are flowcharts showing a monitoring process at the time of detecting a human body. When the monitoring control unit detects a person (human body) in the monitoring area 3 based on the detection signal input from the sensor 100, the monitoring control unit executes the following monitoring process.

  The monitoring control unit starts tracking a person who appears in the monitoring area 3 (step 202), and determines whether the tag reader 102 has detected a wireless tag (step 204). If there is a wireless tag in monitoring area 3, it is recognized as a legitimate user, and the subsequent process recognizes entry / exit from the user's movement and manages the presence / absence of the user (shift to A) .

  Based on the position of the appearance point of the person who is the user, the monitoring control unit determines whether the entry is from the outside of the site to the monitoring area 3 or the entry from the building to the monitoring area 3 (step 302). . In the case of entering from outside the site, the tracking is continued until the person disappears from the monitoring area 3 (step 304). When the person disappears, the person leaves the site based on the position of the disappearance point or inside the building. It is determined whether or not to enter (step 306). If it is determined that the user has entered the building, the user has returned home, so the presence / absence information of the user management information corresponding to the read identification code of the wireless tag is updated to “at home” and the monitoring process is terminated. (Step 308). If it is determined that the user has left the site, the user has once entered the site but has not entered the building and has left the site again. Therefore, the user management information is not updated, and the process ends.

  Also, when it is determined that the person who is the user has entered the monitoring area 3 from the building (No in Step 302), the tracking is continued until the person disappears from the monitoring area 3 in the same manner. (Step 310) Based on the position of the vanishing point, it is determined whether to leave the premises or enter the building (Step 312). If it is determined that the user has left the site, the user has gone out, so the presence / absence information in the user management information corresponding to the read identification code of the wireless tag is updated to “out” and the monitoring process is terminated. (Step 314). If it is determined that the user has entered the building, the user once exits the building but does not go out of the premises but enters the building again, so the processing ends without updating the user management information.

  On the other hand, if the wireless tag cannot be detected in the monitoring area 3 (No in step 204), the detected person is recognized as a person other than the user, and subsequently monitored from outside the site based on the position of the detected appearance point of the person. It is determined whether the entry is to the area 3 or the entry to the monitoring area 3 from the building (step 206). In the case of entering from a building, it is not at least an intruding action by a suspicious person, but for example, when a user forgets to carry a wireless tag and comes out of the building. A voice guidance is output (step 208). In the case of entering from outside the site, there is a possibility that a person who entered the monitoring area 3 is a suspicious person who intends to enter the building and a non-malicious visitor such as a delivery person or acquaintance of delivery. Therefore, recording of the photographed image by the camera 104 is started, and whether or not the person is a suspicious person is checked according to the user's home situation.

  First, the monitoring control unit determines whether the detected person is in the regular monitoring area 4 or the semi-monitoring area 5 based on the detection information by the sensor 100 and the area map information (step 210). In the case of the intrusion into the regular monitoring area 4 (No in Step 210), it is recognized as an intrusion act by a suspicious person, and the photographed image and the acquired voice data are transmitted to the informing terminal 2 in the house and displayed on the informing terminal 2. (Step 212). Then, the captured image data and acquired voice data are transmitted to the monitoring center (step 214), and a warning message is output from the speaker 108 (step 216). In the monitoring center, images and sounds sent from the site are processed in real time, and if necessary, the controller warns a suspicious person via the sensor terminal 1 or dispatches a counselor to the site. In addition, when there is a person at home, the monitoring control unit transmits the image and audio data to the notification terminal 2 in the house, and causes the notification terminal 2 to display and output the data. Note that the notification to the notification terminal 2 may be omitted when there is no resident.

  If it is determined that the intrusion has occurred in the semi-monitoring area 5 (Yes in Step 210), it is checked whether there is a person in the building with reference to the user management information (Step 218). If there is no resident, that is, if the presence / absence information of all users is “going out”, a timer for measuring the residence time is started (step 220). Until the stay determination timer expires, the disappearance of the person being tracked from the monitoring area 3 and the movement of the person being tracked from the semi-monitoring area 5 to the regular monitoring area 4 are monitored (step 222). ~ 226).

  If the person disappears from the monitoring area 3 during the timer timing (Yes in Step 222), the process is terminated without judging abnormality because it is not an intruding act by a suspicious person such as a meter meter reader or a delivery person. On the other hand, when the movement to the regular monitoring area 4 is detected during the timer timing (Yes in step 224) or when the time is up, it is recognized as an intrusion act by a suspicious person, and the captured image and acquired voice data are sent to the monitoring center. And a warning message is output from the speaker 108.

  When it is determined that there is a person at home (Yes in Step 218), the monitoring control unit checks the attributes of the person at home and determines whether or not a user having the confirmation authority is at home (Step 232). If there is even one person who has the authority to confirm (Yes in Step 232), the captured image data and the acquired voice data are transmitted to the notification terminal 2 in the house, and are displayed on the notification terminal 2 (Step 234). The notification to the notification terminal 2 may be performed after detecting a stay for a certain time. The user confirms whether the person who entered the site is a suspicious person or a visitor such as an acquaintance by the image and sound displayed on the notification terminal 2, and when the user recognizes the person as a suspicious person, Operate the notification button. When the notification button is operated, the notification terminal 2 transmits a notification operation signal to the sensor terminal 1.

  After the notification data is transmitted to the notification terminal 2, the reception of the notification operation signal from the notification terminal 2 is awaited until the detected person leaves the monitoring area 3 outside the site (steps 236 to 238). When the notification operation signal is received (Yes in step 236), the user confirms that the user is a suspicious person or a suspicious person, and therefore transmits image and audio data to the monitoring center ( Step 214), a warning message is output from the speaker 108 to warn the suspicious person to stop the crime (Step 216). Also, when audio data is received from the monitoring center, audio is output via the speaker 108. If the disappearance of a person from the monitoring area 3 is detected without performing the reporting operation (Yes in step 238), the monitoring process is terminated without performing reporting or warning to the monitoring center.

  On the other hand, when only a user who does not have the confirmation authority is at home (No in Step 232), the semi-monitoring area 5 is set to the regular monitoring area 4 and the same monitoring process as that of the regular monitoring area 4 is executed. The monitoring control unit transmits the captured image data and the acquired voice data to the in-home notification terminal 2, and causes the notification terminal 2 to display and output the data (step 212). Then, the captured image and acquired voice data are transmitted to the monitoring center, and a warning message is output from the speaker 108 (steps 214 to 216). As a result, the monitoring center can perform real-time processing of images and sounds sent from the site and monitor whether or not the detected person moves suspiciously. Since the monitoring center can be monitored in real time, the output of the warning message may be omitted.

  As described above, the security system according to the present embodiment automatically manages entry / exit of a user without requiring a special operation, and detects an approaching action to a monitoring area around the building, The monitoring process is executed by switching the handling of the monitoring area according to the home status of the user and the attributes of the home. Specifically, a regular monitoring area with strict monitoring standards and a semi-monitoring area with relatively loose monitoring standards are set. If there are only children or elderly people in the house, the monitoring standards in the semi-monitoring area are strict and regular monitoring is performed. The monitoring process equivalent to the area is executed. Thereby, it is possible to appropriately cope with the act of entering the monitoring area according to the user's occupancy status.

  In the security system of the above embodiment, an operation unit for a user to perform a notification operation is provided in the notification terminal, but a notification button may be provided in the wireless tag. In this case, the wireless tag is configured to transmit a notification operation signal triggered by pressing of the notification button, and configured to receive the notification operation signal by a tag reader of the sensor terminal.

  In the security system of the above embodiment, when there is a home person having a confirmation authority, a notification operation is performed by the user to the monitoring center, but the cancel operation is not performed for a predetermined time. It can also be set as the structure reported in case. In this case, a cancel button is provided together with a report button, and when an intruder from the outside is detected, the report button is operated or when the cancel button is not operated within a predetermined time, a notification is sent to the monitoring center. And

  In the security system of the above embodiment, when configured using a plurality of sensor terminals, only one representative sensor terminal is provided with a monitoring processing function by the public wireless communication unit or the above-described monitoring control unit, and other sensors. The terminal may be configured to transmit input information from a sensor, a tag, or the like to a representative sensor terminal.

  Moreover, in the security system of the said embodiment, although it was set as the structure which provides a monitoring processing function and a communication function with a monitoring center in a sensor terminal, you may provide all or one part in a notification terminal in a house. In this case, the notification terminal is provided with a monitoring processing function by a public wireless communication unit or a monitoring control unit, and the sensor terminal is configured to transmit input information from a sensor, a tag, or the like to the notification terminal.

  In addition, the security system of the above embodiment realizes a security system that does not require any special operation by using a wireless tag to determine whether a person existing in the monitoring area is a user. However, it can be replaced by another configuration that can obtain the same effect. For example, as means for identifying a user, biometric authentication (biometric authentication) technology such as face authentication or iris authentication can be applied. By realizing biometric authentication by image processing, the sensor, tag reader, and camera can be replaced by an image sensor in the configuration of the sensor terminal of the above embodiment.

  In the security system of the above embodiment, the presence / absence information is managed based on the entrance / exit of the user who owns the wireless tag.
