  The operation unit 20 includes a reading unit 201 for reading authentication information of the user, and a key input unit 202 operated to set a security set mode or a security release mode. The operation unit 20 allows the reading unit 201 to read the authentication information (ID information) of the user, and after the user is verified, the operation is permitted. The operation unit 20 may be configured by providing a touch panel on the liquid crystal monitor of the display unit 22 and using the touch panel.

  As a reading unit 201 for reading user ID information, a tag reader for reading a wireless signal from an RFID tag, a card reader for reading card information of an IC card or a magnetic card, biometric information acquisition for reading biometrics information such as fingerprints and face images Means or the like may be provided as appropriate.

  The communication unit 21 is a communication interface that connects the security device 2 and the monitoring display device 7. The security device 2 and the monitoring display device 7 are connected via a public network as the network or the Internet. In the present embodiment, an example in which the monitor display device 7 is connected via the recording processing server 5 will be described. However, when the monitor display device 7 can individually communicate externally, the present invention is not limited to this. It may be connected to the monitoring display device 7.

  The display unit 22 is configured of a liquid crystal display, an indicator light, a speaker, and the like. The display unit 22 is installed near or integrally with the operation unit 20, and has a function to display an operation guide or a menu. The display unit 22 may have a function of notifying of voice.

  The input / output unit 23 is an interface to which peripheral devices 26 such as the monitoring camera 1 and a security sensor are connected. The input / output unit 23 is a magnet sensor for detecting the opening and closing of a door arranged at an appropriate place in / outside the area to be a monitoring area, a crime prevention sensor such as an infrared sensor for detecting a human body by infrared rays, a smoke sensor or heat The communication interface is a communication interface connected to a disaster prevention sensor such as a sensor, an emergency button operated by the user, and the like to receive detection signals from various sensors. Each sensor is given a unique identification number, and the detection signal includes this identification number. Further, the input / output unit 23 may be connected to the monitoring camera 1 and outputs an abnormal signal when the security device 2 is determined to be abnormal.

  The storage unit 24 is a program for operating the control unit 25 as the security device 2, sensor information in which types of sensors and sensor installation positions are associated with each ID number of various sensors, and a user who operates the security device 2. It stores registration authentication information for authentication, an operation mode history, and an abnormality history. Further, each time the operation mode is set, the storage unit 24 stores, as an operation mode history, a set time, information on the set user, and information on the set operation mode.

  The control unit 25 has a function of performing various controls of the security device 2. In the present embodiment, the control unit 25 includes a check unit 251, a mode setting unit 252, and an abnormality determination unit 253.

  The collation unit 251 determines whether the user who inputs the operation unit 20 is a user registered in advance. Specifically, the collation unit 251 determines whether the ID information of the user acquired from the operation unit 20 matches the information registered in advance in the storage unit 24 (collation OK). If they match, the user is authenticated as having a valid operation right, and the operation mode of the security device 2 can be shifted by the operation performed through the operation unit 20 (by the mode setting unit 252).

  The mode setting unit 252 sets the operation mode of the security device 2 by the operation of the user determined by the verification unit 251 as the verification OK by the verification unit 251. As an operation mode of the security device 2, at least two types of security set mode and security release mode are set.

  Here, the security set mode is a mode in which when the detection signal is input from the crime prevention sensor, it is determined that an abnormality is detected in the monitoring area, and the center device 4 is notified of an abnormality. Further, the security release mode refers to a mode in which, even if a detection signal is input from the crime prevention sensor, no abnormality detection in the monitored area is made and no abnormality notification is made. The detection signals from the fire sensor and the emergency button are constantly monitored, and an abnormal notification is issued in either of the security set mode and the security release mode. For example, the user operates the operation unit 20 to set the security set mode when the security target is unmanned, and operates the operation unit 20 to set the security release mode when the security target is entered.

  When the operation mode of the security device 2 is set, the mode setting unit 252 transmits a mode setting signal indicating the set operation mode from the communication unit 21 to the recording processing server 5.

  When the abnormality determination unit 253 receives the detection signal from the sensor, the abnormality determination unit 253 compares the current mode and the sensor information of the storage unit 24 to determine the presence or absence of an abnormality. In addition, the abnormality determination unit 253 determines that an abnormality is received when a detection signal is received from any of various sensors when the security set mode is set, and the disaster prevention sensor or the emergency is configured when the security release mode is set. If a detection signal is received from any of the buttons, it is determined that an abnormality is present. The abnormality determination unit 253 transmits an abnormality signal indicating the abnormality from the communication unit 21 to the recording processing server 5 when it is determined that the abnormality is detected. The abnormality signal includes the identification number of the security device 2, the ID number of the sensor that has detected the abnormality, the type of sensor, and the information of the installation position thereof. Further, the abnormality determination unit 253 transmits a recovery signal to the recording processing server 5 when determining that the event is recovered at the transmission source of the detection signal determined to be abnormal.

<Center device>
FIG. 4 is a block diagram showing the configuration of the center device 4. As shown in FIG. 4, the center device 4 includes the recording processing server 5 and the WEB server 6. The recording processing server 5 includes an information storage unit 50, a disaster determination unit 51, an abnormality detection unit 52, an image storage unit 53, an image data conversion unit 54, a monitoring display control unit 55, and a user display control unit 56.

  The information storage unit 50, as installation area information in which the monitoring camera 1 is installed, includes a facility name where the monitoring camera 1 is installed, an address, an area name where an approximate area can be grasped, and a main facility (landmark) in the vicinity Management information corresponding to the information of the camera, the camera number and the identification number of the security device 2 is stored in advance. Further, as the management information, outdoor flag information for identifying whether the installation location is indoor or outdoor is stored as information registered at the time of installation for each monitoring camera 1. If the outdoor flag is ON, it indicates that the device is installed outdoors. The management information is managed as table information provided with various flags, and is updated as needed according to the operation mode setting of the security device 2, the presence or absence of abnormality, the presence or absence of a disaster, and the like.

  In addition, the information storage unit 50 stores, in the management information, the operation mode currently set for each of the security devices 2. When the recording processing server 5 receives a mode setting signal from the security device 2, the operation mode is recorded as current mode information in correspondence with the corresponding security device 2 in the management information. Furthermore, the information storage unit 50 stores an ID and a password as user verification information in association with each monitoring area.

  The disaster determination unit 51 receives disaster information including information on a disaster occurrence area from the information provision source device (external device). For example, when the disaster determination unit 51 receives distribution of disaster information from an information distribution device of a distribution provider of disaster information such as a public organization that is an information providing source device, the disaster determination unit 51 stores this together with the reception time. The disaster information is, for example, an earthquake early warning, but other information related to various disasters, such as information on tsunami prediction, typhoon warning, information on fire, etc. may be distributed as disaster information.

  The disaster determination unit 51 stores in advance a parameter (disaster intensity) indicating the intensity of disaster such as seismic intensity, precipitation, or wind speed as a disaster intensity threshold, and when disaster information exceeding the disaster intensity threshold is received, the disaster Determine the occurrence. When it is determined that a disaster has occurred, the disaster determination unit 51 determines whether any surveillance area is included in the disaster occurrence area, and if it is included, the surveillance camera 1 and the security device corresponding to the surveillance area Turn on the disaster flag for 2 (enable the disaster flag on the management information table). The disaster determination unit 51 turns off the disaster flag when a predetermined period has elapsed since the disaster flag was turned on. The predetermined period is a period set in advance according to the disaster intensity of the disaster information. For example, when the disaster information is an emergency earthquake alert, the predetermined period is set to 1 day when the seismic intensity is 3, and the predetermined period is set to 1 week when the seismic intensity is 6.

  The abnormality detection unit 52 detects an abnormality in the monitoring area based on information (an abnormality signal) input from the monitoring camera 1 or the security device 2. When an abnormality signal is input from the security device 2, the abnormality flag of the corresponding monitoring area in the management information is turned ON (the abnormality flag is enabled on the management information table). Further, when the amount of change is equal to or greater than a predetermined amount based on the image data input from the monitoring camera 1, it may be determined as abnormal. Further, the abnormality detection unit 52 determines the abnormality restoration of the monitoring area based on the information (restoration signal) input from the monitoring camera 1 and the security device 2, and turns off the abnormality flag of the corresponding monitoring area.

  The image storage unit 53 stores image data acquired from the monitoring camera 1 and a data table for managing the image data. The recording area of the image data is divided in advance for each camera or each monitoring area, and the image data of the corresponding monitoring camera 1 is recorded by receiving the image data.

  The data table is information for identifying the recorded image data, and includes a recording ID of the image data, additional information of the image data (camera ID, device type of the monitoring camera 1, device type of used lens, shooting condition , Shooting date and time) are recorded in association with the address information recording the image data.

  The image data conversion unit 54 down-converts the image data acquired from the surveillance camera 1 to a preset definition and converts it into low-definition image data. Specifically, the image data conversion unit 54 down-converts the image data received from the surveillance camera 1 if the image data received from the surveillance camera 1 has a higher image quality than a preset resolution (for example, VGA resolution), Convert to The converted low definition image data is recorded in the image storage unit 53 in correspondence with the basic image data before conversion (image data received from the monitoring camera 1).

  Here, although an example of reducing the resolution as the content of the down conversion is described, the scope of the present invention is not limited to this. The image data conversion unit 54 may reduce the definition by reducing the frame rate, increasing the compression rate, or a combination thereof.

  Further, although an example in which the image data conversion unit 54 performs down conversion at the time of acquiring image data and stores low definition image data in advance has been described here, the scope of the present invention is not limited to this. When outputting image data from the user display control unit 56, the image data conversion unit 54 may perform down conversion and conversion to low definition image data.

  Furthermore, when the disaster flag is already ON for the monitoring camera 1 that has acquired the image data, depending on the number (area or number of areas included) of the disaster occurrence area determined by the disaster determination unit 51, The degree of down conversion (definition) may be made different. For example, as the disaster occurrence area included in the disaster information of the disaster increases, the definition decreases. For example, the case where the disaster occurrence area is “the whole area of Tokyo” is downsized more than the case where “only Chiyoda-ku, Tokyo” is. As a result, the data size of the image data can be reduced as the potential browsing demand increases.

  The monitoring display control unit 55 outputs the image data received from the monitoring camera 1 to the monitoring display device 7 together with the information of the monitoring target and the information of the abnormality. When receiving the image data, the monitoring display control unit 55 outputs the abnormality flag of the corresponding monitoring area in the management information to the monitoring display device 7 if the abnormality flag is ON. Further, when a request for image data is received from the monitoring display device 7, if the abnormality flag of the monitoring area corresponding to the requested image data is ON, this image data is read out from the image storage unit 53 and the monitoring area Are output to the monitoring display unit 7 together with the area information (first area information) for specifying the The area information specifying the monitoring area is, for example, the facility name and address of the monitoring area.

  As described above, the image data provided to the surveillance staff is the image data maintaining the original definition, so that the cause of the abnormality can be grasped from the image, and the evidence of the image can be enhanced. There is. Further, in this case, the monitoring display device 7 displays information for specifying the object to be installed, such as the name and the address of the monitoring area (see FIG. 8).

  The user display control unit 56 reads out low definition image data of the image data corresponding to the requested area when the web server 6 receives the browsing request from the user, and outputs it to the web server 6 together with the area information. And transmit to the user terminal 9. In this case, the user display control unit 56 transmits, together with the low definition image data, an area name (for example, a name of a municipality or the like) from which an approximate area can be grasped as area information (second area information). The area information to be output at this time is information indicating a wide area area range, such as a division of a municipality name.

  Although an example in which the user display control unit 56 receives an area name as area information when the user display control unit 56 receives a browsing request from the user is described here, the scope of the present invention is not limited to this. The area information transmitted here represents an area unit that is wider than area information such as an address specifying at least the monitoring area, and may be information that can not be identified up to the location of the monitoring area.

  When receiving the input of the area information from the user terminal 9 as the browse request signal, the user display control unit 56 extracts the monitoring area corresponding to the area information from the management information. The user display control unit 56 controls so that the user can view the image only for the monitoring camera 1 whose disaster flag of the corresponding monitoring area is ON in the management information and the outdoor flag is ON. Therefore, when the user display control unit 56 receives a browsing request from the user, if the disaster flag of the corresponding monitoring area is ON in the management information, the monitoring camera 1 with the corresponding outdoor flag ON is The low definition image data which is the most recent recording unit is read out and output to the WEB server 6. If the disaster flag is OFF, or if all the corresponding surveillance cameras 1 are outdoor flag OFF, the image data is not read and an error message is returned.

  As described above, the image data provided to the user can be smaller in size than the original image data. As a result, in the peak image providing service for disaster images, even if access is concentrated at the time of a disaster, it is possible to continuously provide images to users while reducing the possibility of processing delays and system outages. It becomes. In this case, the user terminal displays an area name (e.g., the name of a city, etc.) where the approximate area of the monitored area can be grasped (see FIG. 7).

  Note that, as an exception to this process, the user display control unit 56 stores information in the information storage unit 50 when the information specifying the monitoring area and the ID / password are input from the user via the WEB server 6 as an authentication signal. If it is determined that the designated surveillance area or surveillance camera 1 is verified as collated with the collated information, the image browsing is permitted regardless of the disaster flag and the outdoor flag. In this case, not the low-definition image data, but the basic image data (image data received from the monitoring camera 1) which is not down-converted may be output to the user terminal 9. As a result, a legitimate user who is an installation target of the monitoring camera 1 who is a specific user can check the image of his / her management range via the WEB server 6. In this case, the user terminal 9 displays information specifying the property to be installed, such as the name and address of the monitoring area (see FIG. 8).

  The WEB server 6 includes an access receiving unit 60. The access receiving unit 60 has a function of receiving access from the user terminal 9.

  The user accesses the URL of the portal site set in the access receiving unit 60 of the WEB server 6 from the user terminal 9 serving as a client device such as a personal computer or a smartphone using a dedicated application or a WEB browser. It is possible to designate and refer to image data of the monitoring camera 1 that is publicly viewable.

  Further, the user can refer to the image data of the monitoring camera 1 of the monitoring area corresponding to the user by inputting collation information such as a preset ID and password.

  The WEB server 6 receives an access from the user terminal 9 and outputs image data. The WEB server 6 has a web page of a portal site on which is implemented an input unit for specifying area information that the user desires to view image data when accessed by the user, and an input unit for inputting user verification information. Transmit to the user terminal 9. The user designates area information desired to be browsed on the web page, and transmits a browse request signal for requesting image data to the web server 6. For example, it is possible to designate the division of the name of the city or the name of the city or the division of the town area as the area information. In addition, it may be possible to designate a main facility (landmark) in the vicinity as regional information. Alternatively, a user who has acquired collation information from the monitoring center in advance transmits, to the WEB server 6, an authentication signal for requesting authentication by inputting his own collation information.

  The WEB server 6 outputs the information input from the user terminal 9 to the user display control unit 56. When the user display control unit 56 determines that the corresponding image data can be referred to, when providing the image data to the user terminal 9, a known method such as file transfer or streaming may be adopted. The corresponding image data is the image data of the surveillance camera 1 installed outdoors for which the disaster flag is temporarily set to ON due to the occurrence of a disaster, and the surveillance camera 1 that is permitted to browse in advance in correspondence with the collation information ( For example, the user to be installed.

<Monitoring display device>
The monitoring display device 7 is composed of one or more computers and its operation unit and display unit, and displays various information such as image data received from the recording processing server 5 and the name and address of the monitoring area on the display unit An observer constantly monitors the monitoring target. The monitoring display device 7 can access the management information of the recording processing server 5 as a database storing information of the monitoring target and the security device 2 installed there.

  The display unit of the monitoring display device 7 displays information on the monitoring target and information on the abnormality to be dealt with based on the abnormality from the security device 2 and image data of the monitoring camera 1 installed in the monitoring target. For example, information for identifying the object to be installed, such as the name and address of the monitored area is displayed (see FIG. 8). If the observer sees such a display and determines that an abnormality has occurred in the surveillance area, he or she takes necessary measures such as a coping instruction for the person to be monitored. For example, the surveillance staff checks the image data to be received on the display unit, and if the occurrence of a fire such as flame or smoke is recognized, the surveillance staff member is instructed to cope with the surveillance target and a 119 alarm is issued.

  The operation of the image confirmation system configured as described above will be described with reference to the drawings.

  In the image confirmation system according to the embodiment of the present invention, when an image of the monitoring camera 1 is confirmed by the monitoring display device 7 at the time of abnormality, monitoring display control as shown in FIG. 5 is executed. The monitoring display control is executed by the recording processing server 5 (mainly the monitoring display control unit 55) of the center device 4.

  Monitoring display control is executed when an abnormality is detected in the monitoring area. Therefore, first, the recording processing server 5 determines whether an abnormality is detected in the monitoring area (S1). Then, when an abnormality is detected, image data of the monitoring area (monitoring area in which the abnormality is detected) is provided to the monitoring display device 7 so that the supervisor can select it (S2). When the surveillance staff selects image data (for example, by clicking on the image) on the surveillance display device 7, the recording processing server 5 reads out the selected image data (S3), and the image data and the installation target ( Information (such as the name and address of the monitoring area) for specifying the monitoring area is output to the monitoring display device 7 (S4). In this case, together with the image data, information (such as the name and address of the monitoring area) specifying the installation target (monitoring area) is displayed on the monitoring display device 7 (see FIG. 8). The output of the image data thus selected is repeated until the abnormality is recovered. Thereafter, when the abnormality in the monitoring area is recovered (S5), the output of the image data is inhibited (S6), and the process is ended.

  In the image confirmation system according to the embodiment of the present invention, when the user terminal 9 confirms the image of the monitoring camera 1 at the time of a disaster, the user display control as shown in FIG. . The user display control is executed by the recording processing server 5 (mainly the user display control unit 56) of the center device 4.

  The user display control is executed when there is a browsing request from the user terminal 9 via the WEB server 6. When there is a browsing request from the user terminal 9 (S10), first, it is determined whether the user is a specific user (S11). If it is not a specific user (that is, if it is a general user without input of unique collation information), it is determined whether or not the disaster flag of the monitoring area requested to be browsed is ON (S12). If the disaster flag is ON, it is determined whether there is an image of the monitoring camera 1 that can be browsed (S13). The viewable surveillance camera 1 is the surveillance camera 1 whose disaster flag is ON and whose outdoor flag is ON.

  If there is an image of the monitor camera 1 that can be browsed, the low definition image of the monitor camera 1 is read out (S14), and the low definition image and the area information of the monitor camera 1 are output to the user terminal 9 S15). In this case, along with the low definition image, the user terminal 9 displays an area name (for example, classification of a municipality name or division of a town area, etc.) where the approximate area of the monitoring area can be grasped (see FIG. 7). . Thereafter, it is determined whether the disaster flag has been turned OFF (S16). When the disaster flag is turned off, the output of the low definition image is inhibited (S17), and the process is ended. In addition, even if the disaster flag remains ON, if the input of viewing end is received from the user terminal 9 (S18), the processing ends.

  When the user is a specific user, the authentication signal input from the web server 6 is collated with the verification information to identify the monitoring area corresponding to the specific user (S19), and the image data of the monitoring area Are provided to the user terminal 9 so that the user can select (S20). When the user selects image data at the user terminal 9 (for example, by clicking on the image), the recording processing server 5 reads the selected image (S21), and the image data and the installation target (monitoring Information (such as the name and address of the monitoring area) specifying the area is output to the user terminal 9 (S22). In this case, the user terminal 9 displays, together with the image data, information (such as the name and address of the monitoring area) specifying the installation target (monitoring area) (see FIG. 8). Thereafter, when the input of viewing end is received from the user terminal 9 (S23), the process is ended.

  In the image confirmation system of the present embodiment, the image data received from the monitoring camera 1 is transmitted from the center device 4 to the monitoring display device 7 and the user terminal 9. At the monitoring center for crime monitoring purposes, where surveillance personnel are always resident and monitor the presence or absence of abnormalities, and at portal sites for disaster situation confirmation purposes, where many users check images at their own time in the event of a disaster, The characteristics are different. In the present invention, in the case of a monitoring video for abnormality monitoring, information (such as the name and address of the monitoring area) specifying the installation target (monitoring area) is transmitted to the monitoring display 7 together with the image data. In the case of a disaster video for the purpose of status confirmation, an area name (for example, a municipality name or the like) that can grasp an approximate area of the monitoring area is transmitted to the user terminal together with the image data. Thus, the installation target of the monitoring camera 1 can be specified at the time of abnormality, while the installation target can not be specified at the time of confirmation of a disaster situation, and privacy can be protected.

  Further, in the present embodiment, when an abnormality occurs in the installation target, the center apparatus 4 detects the abnormality and information (image area and name of the monitoring area) specifying the image data of the installation target and the installation target (monitored area) Etc.) are sent to the monitoring display unit 7. As described above, abnormality detection of the installation object and image data transmission are automatically performed by the center apparatus 4, and in the case of abnormality, the installation object of the monitoring camera 1 can be specified concretely. Further, since the image viewing from the monitoring display device 7 is prohibited when the abnormality is recovered, privacy can be ensured.

  Further, in the present embodiment, when a disaster occurs, it is determined whether the monitoring camera 1 is installed in the disaster occurrence area based on the installation area information where the monitoring camera 1 is installed and the information of the disaster occurrence area. Be done. Then, only for the monitoring camera 1 installed in the disaster occurrence area, in response to a request signal from the user terminal 9, the image data and an area name (for example, a municipality name etc.) where the approximate area of the monitoring area can be grasped Sent to 9 This makes it possible to protect privacy at the time of confirmation of a disaster situation.

  Further, in the present embodiment, for the image data received from the monitoring camera 1 corresponding to the specific user, the image data to be installed and the installation target (monitoring area) are specified to the user terminal 9 of the specific user. Image data is sent along with information (such as the name and address of the surveillance area). Thereby, the specific user (a legitimate user who is the installation target of the monitoring camera) confirms the image of the monitoring camera 1 in the management range of his own at the portal site etc., and the installation target of the monitoring camera 1 is specifically It can be identified.
