FIG. 4 is a diagram showing an example of the functional configuration of the monitoring system 1. The monitoring system 1 functions as a generation means 101, a transmission means 102, a reception means 103, a calculation means 104, a setting means 105, and an output means 106. Although two communication terminals 10 are shown in FIG. 4, these communication terminals 10 may be the same communication terminal 10 or different communication terminals 10.

In this example, the generating means 101 and the transmitting means 102 are mounted on the communication terminal 10. The generation means 101 is realized by a combination of a program stored in the memory 12 and a processor 11 that executes the program. The transmission means 102 is realized by a combination of a program stored in the memory 12, a processor 11 that executes the program, and a communication interface 13 that operates under the control of the processor 11.

The receiving means 103, the calculating means 104, the setting means 105, and the output means 106 are mounted on the server device 20.

The receiving means 103 and the output means 106 are demonstrated by a combination of a program stored in the memory 22, a processor 21 that executes the program, and a communication interface 23 that operates under the control of the processor 21. The calculation means 104 and the setting means 105 are realized by a combination of a program stored in the memory 22 and a processor 21 that executes the program.

The generation means 101 generates post information including information about the object perceived by each user. Here, a suspicious object witnessed by the user will be described as an example of an object perceived by the user. The information about the object includes, for example, at least one of information indicating the fact that the object has been perceived, image data indicating the image of the object, and feature information of the object. This posted information means, for example, information voluntarily sent by the user. The transmission means 102 transmits the posting information generated by the generation means 101 to the server device 20. In addition, as another example of the object perceived by each user, information such as a suspicious person witnessed by the user, a phenomenon such as a fire, an abnormal noise heard by the user, an explosion sound, or an offensive odor smelled by the user is targeted. You may try to do it.

The receiving means 103 receives the posted information transmitted from the transmitting means 102. The calculation means 104 calculates the number of posted information received by the receiving means 103. The setting means 105 sets a value indicating the degree of need for countermeasures for the target based on the number of posted information calculated by the calculation means 104. This value is, for example, a value indicating the possibility that a countermeasure is required for the countermeasure object. For example, the larger the value, the more likely it is that action will be required. For this value, for example, a coping level is used. This value is set with reference to, for example, the setting table 111. The setting table 111 is stored in the storage 24 in advance, for example.

The output means 106 outputs information according to the value set by the setting means 105. This information may be the value itself or the information corresponding to the value. The concept of the term "output" includes transmission.

In the following description, when the communication terminal 10 is described as the main body of the process, the process is specifically a combination of the program stored in the memory 12 and the processor 11 that executes the program, or these. , Means that it is executed in combination with the communication interface 13 that operates under the control of the processor 11. The same applies to the server device 20.

Operation FIG. 5 is a sequence chart showing an example of the operation of the monitoring system 1. FIG. 6 is a diagram showing an example of the monitored area 200 of the monitoring system 1. In this example, the monitoring system 1 monitors the suspicious object in the area 200. The area 200 is divided into areas A1 to A4. The area setting is not limited to the example of equal division as shown in FIG. 6, and the size may be set individually according to the area (commercial area, residential area), the shape of the structure, the road, and the like. In addition, a predetermined range including the first posted position may be set dynamically as an area.

Here, it is assumed that the spectator 201 in the area A1 witnesses a suspicious object. In the following description, the communication terminal 10 used by the spectator 201 is referred to as "communication terminal 10A". Audience 201 uses the input device 15 to perform an operation to generate posting information. This operation may be performed, for example, on the post information generation screen 210 displayed on the display device 16.

FIG. 7 is a diagram showing an example of the posting information generation screen 210. The generation screen 210 includes a preview area 211, a text box 212, and a post button 213. An image of a suspicious object is displayed in the preview area 211. For example, when the audience 201 captures an image of a suspicious object with the camera 17, the captured image is displayed in the preview area 211. The text box 212 is used for inputting text information regarding a suspicious object. This textual information may only indicate the fact that the suspicious object has been witnessed, or may include information indicating this fact as well as characteristic information indicating the characteristics of the suspicious object. This feature information may include, for example, information indicating the size, shape, color, or movement of a suspicious object. The post button 213 is used for an operation of transmitting post information. When the spectator 201 finishes generating the posting information, the spectator 201 presses the posting button 213 using the input device 15.

When the post button 213 is pressed, the process of step S101 shown in FIG. 5 is started. In this example, the processing of the following steps S101 and S102 is performed by the communication terminal 10A.

In step S101, the generation means 101 generates post information about the suspicious object in response to the operation of the spectator 201. In this example, the posted information includes image data indicating an image displayed in the preview area 211 shown in FIG. 7 and text information input in the text box 212. Attribute information is added to this image data. The attribute information includes position information indicating the position where the image was taken (hereinafter referred to as "shooting position") and date and time information indicating the date and time when the image was taken (hereinafter referred to as "shooting date and time"). included. As the position information indicating the photographing position, for example, information indicating the position of the communication terminal 10 measured by the positioning sensor 18 when the image is photographed is used. As the date and time information indicating the shooting date and time, for example, information indicating the date and time measured by the timekeeping function when the image is shot is used.

The posted information does not necessarily have to include image data. When the posted information does not include image data, the posted information does not include the position information indicating the shooting position and the date and time information indicating the shooting date and time.

In step S102, the transmission means 102 transmits the posting information generated in step S101 to the server device 20. This post information includes location information indicating the position where the post information was transmitted (hereinafter referred to as "post position") and date and time information indicating the date and time when the post information was transmitted (hereinafter referred to as "post date and time"). And a user ID that uniquely identifies the communication terminal 10A of the audience 201. As the position information indicating the posting position, for example, information indicating the position of the communication terminal 10 measured by the positioning sensor 18 when the posting information is transmitted is used. As the date and time information indicating the posting date and time, for example, when the posting information is transmitted, information indicating the date and time measured by the timekeeping function is used. The user ID may be stored in the storage 14 in advance. For example, the user ID may be an individual identification number, an e-mail address, or the like of the communication terminal 10. Further, when the posting function of the present embodiment is provided as a specific application, a user ID may be set when the application is installed on the communication terminal 10 and stored in the storage 14. The set user ID is also stored in the server device 20. When the user ID of the audience 201 is "U001", the posted information includes this user ID "U001". In the server device 20, the receiving means 103 receives the posted information from the communication terminal 10A.

In step S103, the server device 20 stores the received post information in the storage 24. In this way, the storage 24 stores the posted information transmitted from the plurality of communication terminals 10.

In step S104, the calculation means 104 calculates the number of posted information (hereinafter, referred to as “posted number”) stored in the storage 24 for each area. The process of step S104 may be performed every time new posted information is stored in step S103, or may be performed at a predetermined timing.

In the example shown in FIG. 6, the number of posts is calculated for each of the areas A1 to A4. The number of posts in area A1 is calculated according to the number of posted information regarding suspicious objects witnessed in area A1. In which area each posted information is related to a suspicious object witnessed is determined based on, for example, the position information indicating the posted position or the position information indicating the shooting position included in the posted information. For example, when the posting position is a position in the area A1, it may be determined that the posting information is related to a suspicious object witnessed in the area A1. Further, when the shooting position is a position in the area A1, it may be determined that the posted information is related to a suspicious object witnessed in the area A1.

Further, the calculation means 104 may calculate the number of posts by regarding the posted information as one posted information when the posted information is transmitted a plurality of times from the same person. For example, assume that the audience 201 transmits the posted information twice. In this case, the storage 24 stores two posting information including the user ID "U001" of the audience 201. These posted information may be regarded as one posted information and the number of posts may be calculated. That is, for these posted information, the number of posts may not be added by 2, but only by 1.

Returning to FIG. 5, in step S105, the setting means 105 sets the coping level for each area with reference to the setting table 111.

FIG. 8 is a diagram showing an example of the setting table 111. In the setting table 111, the range of the number of posts and the coping level are stored in association with each other. The range of the number of posts is defined by using at least one of the first threshold and the second threshold. The first threshold is set to, for example, the number of posts that are likely to require normal action against suspicious objects. The second threshold is set to, for example, the number of posts that are considered to require a high degree of urgency for dealing with suspicious objects. The second threshold value is a value larger than the first threshold value. For example, the first threshold may be 5 and the second threshold may be 10. Coping levels include 1, 2, and 3. For example, a coping level "1" means that it is unlikely that a suspicious object needs to be dealt with. The coping levels "2" and "3" both mean that it is highly likely that a suspicious object needs to be dealt with. In particular, the coping level "3" means that the urgency of coping with a suspicious object is high. The coping level increases as the number of posts increases.

For example, in the setting table 111, the number of posts "less than the first threshold value" and the coping level "1" are stored in association with each other. This indicates that when the number of posts is less than the first threshold value, the coping level "1" is set. For example, when the number of posts in area A1 is less than the first threshold value, 1 is set as the coping level of area A1.

Further, in the setting table 111, the number of posts "greater than or equal to the first threshold value and less than the second threshold value" and the coping level "2" are stored in association with each other. This indicates that the coping level "2" is set when the number of posts is equal to or greater than the first threshold and less than the second threshold. For example, when the number of posts in the area A1 is equal to or greater than the first threshold and less than the second threshold, 2 is set as the coping level of the area A1.

Further, in the setting table 111, the number of posts "2nd threshold value or more" and the coping level "3" are stored in association with each other. This indicates that when the number of posts is equal to or greater than the second threshold value, the coping level "3" is set. For example, when the number of posts in area A1 is equal to or greater than the second threshold value, 3 is set as the coping level of area A1.

Returning to FIG. 5, in step S106, the output means 106 transmits the notification information including the coping level set in step S105 to the operation terminal 30. In the following description, the post information that is the basis for setting this coping level is referred to as "target post information". In addition to the coping level, this notification information includes, for example, date and time information indicating the posting date and time included in the target posting information, date and time information indicating the shooting date and time, position information indicating the posting position, position information indicating the shooting position, and image data. At least one of the feature information and the user ID may be included. These pieces of information may be obtained from one target post information, or may be obtained from a plurality of target post information. The operation terminal 30 receives the notification information from the server device 20.

In step S107, the operation terminal 30 notifies the operator that an abnormality has been detected according to the notification information received from the server device 20. This notification may be performed, for example, on the monitoring screen 220 displayed on the display device of the operation terminal 30. Note that this notification does not have to be given according to all the notification information. For example, this notification may be given only when the response level included in the notification information is 2 or higher.

FIG. 9 is a diagram showing an example of the monitoring screen 220. The monitoring screen 220 includes a case image 221, case detailed information 222, a normal response instruction button 223, and an emergency response instruction button 224. The case image 221 is an image showing a case in which an abnormality is detected. As the case image 221, for example, an image indicated by image data included in the notification information may be used. The case detailed information 222 is information indicating the details of the case in which the abnormality is detected. The case detailed information 222 may include, for example, information indicating the time when the abnormality occurred, information indicating the place where the abnormality occurred, and information indicating the poster who posted the abnormality. As the information indicating the time when the abnormality occurs, for example, date / time information indicating the posting date / time or shooting date / time information included in the notification information may be used. As the information indicating the place where the abnormality has occurred, for example, the position information indicating the posting position or the position information indicating the shooting position included in the notification information may be used. As the information indicating the poster, for example, the user ID included in the notification information may be used.

For example, when notification information including two or more coping levels is received, a new case occurs on the monitoring screen 220. At this time, a new case image 221 and case detailed information 222 corresponding to the abnormality notified by the notification information are added on the monitoring screen 220. As a result, the operator is notified that a new abnormality has been detected.

Further, the content of the case detailed information 222 may be changed depending on the coping level included in the notification information. For example, the case detail information 222 may include a coping level. Further, the display method of the case image 221 may be changed depending on the coping level. For example, the case image 221 corresponding to the case having the coping level 3 may be arranged at a position more prominent than the case image 221 corresponding to the case having the coping level 2, for example, above the monitoring screen 220. Further, for example, the case image 221 corresponding to the case having the coping level of 3 may be highlighted and displayed. When such a display is made, the case image 221 may be changed, for example, in at least one of color, shape, and size.

The operator refers to the monitoring screen 220 and comprehensively considers various situations to determine whether or not to take measures against the notified abnormality. In addition, when dealing with a suspicious object, the operator determines the type of dealing. Types of this action include, for example, normal action and emergency action. These measures are measures with different urgency. Emergency response is a response that is more urgent than normal response. When it is determined that the normal action is to be taken, the operator presses the normal action instruction button 223 using the input device of the operation terminal 30. On the other hand, when it is determined that the emergency response is to be taken, the operator presses the emergency response instruction button 224 using the input device of the operation terminal 30. In this way, when the normal response instruction button 223 or the emergency response instruction button 224 is pressed, the process proceeds to step S108 shown in FIG.

In step S108, the operation terminal 30 transmits a coping instruction to the server device 20. The server device 20 receives a coping instruction from the operation terminal 30. This coping instruction includes, for example, the type of coping.

In step S109, the output means 106 is suspicious of the communication terminal 10 used by a person (hereinafter, referred to as a “handling person”) who plays a role of dealing with a suspicious object in response to a coping instruction received from the operation terminal 30. Send coping instructions for things. Coping personnel include, for example, at least one of security guards and staff. In the following description, the communication terminal 10 used by the coping staff is referred to as "communication terminal 10B". The communication terminal 10B is at least one communication terminal 10, and may be a plurality of communication terminals 10.

In addition to the type of coping, the coping instruction includes, for example, image data indicating an image of a suspicious object and position information indicating the position of the suspicious object. As the image data, for example, image data included in the target posted information may be used. As the position information, for example, position information indicating the posting position included in the target posting information or position information indicating the shooting position may be used. In addition, the coping instruction may include characteristic information indicating the characteristics of the suspicious object.

If the type of action included in the received action instruction is normal action, the normal action instruction is transmitted. On the other hand, if the type of response included in the received response instruction is emergency response, the emergency response instruction is transmitted. These coping instructions may be sent only to those who are near the suspicious object among the coping personnel. The person near this may be a person in the same area or a person in an adjacent area. Further, the contents of these coping instructions may be different. For example, the emergency response instruction may include information indicating that the degree of emergency is high. Further, these coping instructions may have different attributes of the recipient. For example, normal response instructions may be sent to staff and guards, while emergency response instructions may be sent only to guards. Further, these coping instructions may have different numbers of destinations. For example, the normal response instruction may be transmitted to the two communication terminals 10B, whereas the emergency response instruction may be transmitted to the five communication terminals 10B.

In the example shown in FIG. 6, the guard 202 exists in the area A1, the staff 203 and the guard 204 exist in the area A3 next to the area A1, and the guards 205 to 207 exist in the area A2 next to the area A1. To do. In this case, the normal handling instruction for the suspicious object in the area A1 may be transmitted to the communication terminal 10B of the guard 202 and the communication terminal 10B of the staff 203. On the other hand, the emergency response instruction for the suspicious object in the area A1 may be transmitted to the communication terminals 10B of the guards 202 and 204 to 207. The communication terminal 10B receives a coping instruction from the server device 20.

In step S110, the communication terminal 10B causes the display device 16 to display the instruction screen 230 corresponding to the received coping instruction. FIG. 10 is a diagram showing an example of the instruction screen 230. In this example, the instruction screen 230 includes an image 231 of the suspicious object and information 232 indicating the position of the suspicious object, as well as a text instructing to deal with the suspicious object witnessed in the area A1. As the image 231 of the suspicious object, for example, an image indicated by the image data included in the coping instruction may be used. As the information 232 indicating the position of the suspicious object, for example, the position information indicating the posting position included in the coping instruction or the position information indicating the shooting position may be used.

Looking at the instruction screen 230, the coping person moves to the area A1 and deals with the suspicious object. This coping may include, for example, finding a suspicious object and taking measures to prevent others from touching the suspicious object. Further, the measures may include confirmation of the suspicious object and appropriate measures for the suspicious object.

In the above example, since the audience transmits the posted information, the communication terminal 10 for transmitting the posted information and the communication terminal 10 for receiving the coping instruction are different communication terminals 10. However, it is not always necessary that the communication terminal 10 for transmitting the posted information and the communication terminal 10 for receiving the coping instruction are different communication terminals 10. For example, when a security guard or a staff member transmits posted information, the communication terminal 10 for transmitting the posted information and the communication terminal 10 for receiving the coping instruction may be the same communication terminal 10.

According to the above-described embodiment, the response level is set based on the number of posts of posted information regarding the suspicious object sent by the user. The operator makes a decision on how to deal with a suspicious object by referring to this coping level. By utilizing the posted information transmitted by an unspecified number of people in this way, a suspicious object can be found more quickly. In addition, when the number of posted information is large to some extent, the credibility of these posted information is considered to be high. That is, it is highly likely that it is necessary to deal with suspicious objects. Therefore, it is possible to reduce inappropriate judgments when deciding how to deal with suspicious objects.

Modifications The present invention is not limited to the above-described embodiments. Various modifications may be made to the above-described embodiment. Moreover, the following modification examples may be carried out in combination.

Modification 1
In the above-described embodiment, the server device 20 may change the threshold value based on the area to which the position of the suspicious object belongs. In this case, the server device 20 includes a changing means for changing the threshold value. This changing means is realized, for example, by a combination of a program stored in the memory 22 and a processor 21 that executes the program. For example, the changing means refers to the changing table 112 and changes at least one of the first threshold value and the second threshold value based on the shooting position indicated by the position information included in the posting information or the area to which the posting position belongs. You may. The change table 112 is stored in the storage 24 in advance, for example.

FIG. 11 is a diagram showing an example of the change table 112. In the change table 112, the area identification information and the threshold value are stored in association with each other. This threshold value may include both the first threshold value and the second threshold value, or may include only one of the first threshold value and the second threshold value.

For example, in the change table 112, the area identification information “A1” is stored in association with the first threshold value “3” and the second threshold value “5”. This indicates that the first threshold of area A1 is 3 and the second threshold is 5. In this case, the first threshold of area A1 is changed to 3, and the second threshold is changed to 5. As a result, for example, when the number of posts in area A1 reaches 3, the coping level of area A1 is changed from 1 to 2. When the number of posts in area A1 reaches 5, the coping level in area A1 is changed from 2 to 3.

In the example shown in FIG. 11, the change table 112 stores the threshold values corresponding to all of the areas A1 to A4, but only the threshold values corresponding to a part of the areas A1 to A4 may be stored. .. For example, of the areas A1 to A4, only the threshold value corresponding to the important area may be stored. In this case, a preset value may be used for the threshold value of the other area.

According to this modification, for example, for an important area, the degree of change in the coping level can be different for each area, such as raising the coping level even if the number of posts is small.

Modification 2
In the above-described embodiment, the server device 20 may change the threshold value based on the degree of congestion in the area to which the position of the suspicious object belongs. In this case, the server device 20 includes a changing means for changing the threshold value. This changing means is realized, for example, by a combination of a program stored in the memory 22 and a processor 21 that executes the program. For example, the changing means may change at least one of the first threshold value and the second threshold value based on the shooting position indicated by the position information included in the posting information or the area to which the posting position belongs. This area is an example of the range to which the position indicated by the position information included in the posted information belongs.

For example, when the degree of congestion in the area A1 is equal to or less than a predetermined degree of congestion, the changing means may reduce at least one of the first threshold value and the second threshold value. This predetermined degree of congestion is set according to, for example, the number of people whose number of posts is considered to be difficult to reach the first threshold value or the second threshold value. For example, when the degree of congestion is equal to or less than a predetermined degree of congestion, the first threshold value may be changed from 5 to 3, and the second threshold value may be changed from 10 to 5. The amount of change in the threshold value may be predetermined for each of the first threshold value and the second threshold value, for example.

For this degree of congestion, for example, the population density of each area may be used. This population density may be measured, for example, by analyzing an image of each area taken from the sky. This measurement may be performed by the server device 20 or by an external device capable of communicating with the server device 20. In either case, the server device 20 includes an acquisition means for acquiring the degree of congestion. This acquisition means is realized, for example, by a combination of a program stored in the memory 22, a processor 21 that executes the program, and a communication interface 23 that operates under the control of the processor 21.

In another example, the degree of congestion may be, for example, the degree of density of a person who has a communication terminal 10 in each area. In this case, the degree of congestion may be measured using, for example, the number of communication terminals 10 connected to the base station.

In another example, the posted information may be transmitted only to the communication terminal 10 in which a specific application program is installed. In such a case, the degree of congestion of a person who has a communication terminal 10 in which a specific application program of each area is installed may be used as the degree of congestion. Such a communication terminal 10 is connected to the server device 20 via the communication line 40, for example, when a specific application is started. In this case, the degree of congestion may be measured using the number of communication terminals 10 connected to the server device 20 in this way.
Alternatively, a value predicted from the data obtained by measuring the number of people in the past may be used as the degree of congestion. For example, the number of people measured for each time zone measured at a plurality of places may be accumulated, and the predicted value of the congestion situation may be obtained according to the position and time of each area, and this may be used as the degree of congestion.

When the degree of congestion is low, the number of posts is difficult to reach the threshold because the population parameter of the person who sends the posted information is small. According to this modification, in an area with a low degree of congestion, even if the number of posted information transmitted from the area is small, the level of coping with the target of the posted information can be raised.

Modification 3
In the above-described embodiment, the server device 20 may change the threshold value according to the amount of increase in the posted information. In this case, the server device 20 includes a changing means for changing this threshold value. This changing means is realized, for example, by a combination of a program stored in the memory 22 and a processor 21 that executes the program. For example, the changing means may reduce at least one of the first threshold value and the second threshold value when the increase amount of the number of posts is equal to or more than a predetermined increase amount. For example, when the amount of increase in the number of posts is equal to or greater than the predetermined amount of increase, the first threshold value may be changed from 5 to 3, and the second threshold value may be changed from 10 to 5. The amount of change in the threshold value may be predetermined for each of the first threshold value and the second threshold value, for example.

Further, when the increase amount of the posted information is equal to or more than the predetermined increase amount, the maximum coping level 3 may be set regardless of the number of posts.

If the posted information increases rapidly, it is considered that there is a high degree of urgency to deal with the target of the posted information. According to this modification, when the posted information increases rapidly, the level of coping with the target of the posted information can be raised even if the number of posted information is small.

Modification 4
In the above-described embodiment, the server device 20 may change the threshold value according to the passing situation of a specific person. In this case, the server device 20 includes a changing means for changing the threshold value. This changing means is realized, for example, by a combination of a program stored in the memory 22 and a processor 21 that executes the program.

A particular person is, for example, a top runner participating in a marathon event. Here, it is assumed that the top runner passes through the area A1 between 10:00 and 10:15. Information indicating the time for the Top Runner to pass through each area may be predetermined or may be acquired from an external device capable of communicating with the server device 20. In this case, the changing means may reduce at least one of the first threshold value and the second threshold value of the area A1 only during this time. For example, between 10:00 and 10:15, the first threshold value may be changed from 5 to 3, and the second threshold value may be changed from 10 to 5. The amount of change in the threshold value may be predetermined for each of the first threshold value and the second threshold value, for example.

In areas where important people pass, it is considered that the urgency of dealing with suspicious objects is high. According to this modification, when a specific person passes through, even if the number of posted information is small, the level of coping with the target of the posted information can be raised.

Modification 5
In the above-described modifications 1 to 4, the communication terminal 10 may transmit information for changing the threshold value to the server device 20. For example, when the threshold value is changed depending on the area as in the above-mentioned modification 1, the communication terminal 10 changes the threshold value corresponding to the area to which the position indicated by the position information included in the posted information belongs together with the posted information. Information indicating the above may be transmitted to the server device 20. In this case, the server device 20 does not have to store the change table 112. The same applies to other modified examples.

Modification 6
In the above-described embodiment, the calculation means 104 may refer to the weighting table 113 and weight the number of posts according to the attributes of the user. The attribute of this user may be determined based on the user ID included in the posted information. For example, the attributes of the user may be predetermined for each user ID of the user. In another example, the user ID of the staff and the user ID of the guard may be registered in advance. In this case, for example, when the user ID included in the posted information is not registered, the attribute of the user who posted the posted information may be determined to be "general public". The weighting table 113 is stored in the storage 24 in advance, for example.

FIG. 12 is a diagram showing an example of the weighting table 113. In the weighting table 113, the attribute information indicating the user's attribute and the weighting coefficient are stored in association with each other. User attributes include the general public, staff, and security guards. The general public is a person other than staff and security guards. The general public includes the audience. The weighting factor is a positive value. For example, the higher the reliability of the user's attribute, the larger the weighting coefficient.

For example, in the weighting table 113, the attribute information "general person" and the weighting coefficient "1" are stored in association with each other. This indicates that weighting is not performed when the weighting coefficient is 1. For example, when one post information is posted by the general public, the number of posts is added by one. This post means sending post information.

Further, in the weighting table 113, the attribute information "staff" and the weighting coefficient "2" are stored in association with each other. This indicates that the number of posts is weighted using the weighting coefficient "2" for the posted information posted by the staff. For example, if one post information is posted by the staff, the number of posts is added by two. That is, when the posted information is posted by the staff, the value added to the number of posts is doubled as compared with the case where the posted information is posted by the general public.

Further, in the weighting table 113, the attribute information “security guard” and the weighting coefficient “5” are stored in association with each other. This indicates that the number of posts is weighted using the weighting coefficient "5" for the posted information posted by the guards. For example, if one post information is posted by a security guard, the number of posts is added by 5. That is, when the posted information is posted by a security guard, the value added to the number of posts is five times as much as when the posted information is posted by the general public.

Posting information posted by staff or security guards is considered to be more credible than posted information posted by the general public. According to this modification, even if the number of posts is small, it is possible to raise the coping level corresponding to the posted information for such highly credible posted information.

Modification 7
In the above-described embodiment, the calculation means 104 may calculate the number of posts of the posted information transmitted within a predetermined period among the posted information received by the receiving means 103. The time when the posted information is posted is indicated by, for example, date and time information indicating the posting date and time included in the posted information. For example, when the predetermined period is 30 minutes, the number of posts is calculated based on the posted information transmitted between 30 minutes before the current time and the current time.

If the posted information was sent at very different times, the posted information may be about different suspicious objects. According to this modification, the possibility that the number of posts is calculated based on the posted information about different suspicious objects can be reduced.

Modification 8
In the above-described embodiment, the calculation means 104 may calculate the number of posted information regarding suspicious objects having the same or similar characteristics among the posted information received by the receiving means 103. In this case, the characteristics of the suspicious object that is the target of the posted information are extracted based on the posted information. This extraction may be performed, for example, by analyzing the image data included in the posted information, or by analyzing the feature information included in the posted information. For example, the number of posted information in which the similarity of the extracted features is equal to or higher than a predetermined similarity may be calculated. This predetermined similarity is set to, for example, a similarity that can be regarded as the same suspicious object.

If the characteristics of the suspicious objects recognized from the posted information are significantly different, the posted information may be related to different suspicious objects. According to this variant, it is possible to reduce the possibility that the number of posts will be calculated based on the number of posts about different suspicious objects.

Modification 9
In the above-described embodiment, the coping instruction may be output without the operation of the operator. For example, the output means 106 may output a coping instruction for a suspicious object according to the coping level set by the setting means 105. For example, the output means 106 may output a coping instruction for a suspicious object when the coping level set by the setting means 105 is equal to or higher than the reference value. This reference value is a value at which it is highly likely that a suspicious object needs to be dealt with. This reference value may be 2, for example. In this case, if the coping level is 2, a normal coping instruction may be output, and if the coping level is 3, an emergency coping instruction may be output. According to this modification, it is possible to reduce the labor of the operation of giving the coping instruction.

Modification 10
In the above-described embodiment, the target for implementing the function of the monitoring system 1 is not limited to the example shown in FIG. For example, some of the functions implemented in the server device 20 may be implemented in an external device capable of communicating with the server device 20.

The processing steps performed in the monitoring system 1 are not limited to the examples described in the above-described embodiment. The steps of this process may be swapped as long as there is no contradiction. The present invention may be provided as a monitoring method including steps of processing performed in the monitoring system 1.
