You may output the produced | generated audio | voice from the speaker 203 as needed.

  The voice for the loudspeaker broadcast generated by the text generation function 201a for the loudspeaker broadcast or the voice for the loudspeaker broadcast generated by the voice conversion function 201b is regenerated according to the correction content when the correction instruction from the input unit 207 is received. The

  When a loudspeak broadcast instruction is issued from the input unit 207, the sound for the loudspeak broadcast is transmitted to the base station specified by the center station antenna 13 or all the terminal stations 30 via the radio I / F 210 and the base station radio transceiver 1 or / And wirelessly transmitted to the door-to-door receiver 40. When the terminal station 30 receives the sound for loud sound broadcasting, the sound for loud sound broadcasting is loudly broadcast from the trumpet speaker 34 via the wireless unit 32 and the control unit 31.

  A radio communication method in a radio communication system which is an embodiment of the information communication system of the present invention will be described with reference to FIG. Here, the process from detecting an abnormal event with the camera to implementing the loudspeaker will be described.

  The camera 35 installed in the terminal station device 30 captures an image of the monitoring area and acquires an image by converting incident light into an electrical signal by the image acquisition unit 36 (S1). The acquired image is subjected to image processing by the image processing unit 37, and the presence or absence of an abnormal event is determined (S2). If an abnormal event is detected (Yes), the process proceeds to S3. If no abnormal event is detected (No), the process of S1 is repeated.

  Here, the determination of the abnormal event in S2 will be described. For example, if the water level is increased, a certain mark is set. If the water level reaches the mark in the acquired image, it can be determined that the water level has increased. If it is a fire, an infrared sensor is used for the image acquisition unit 56, and fluctuations are detected in the image. If a certain high-temperature area exists for a certain period of time, it can be judged as a fire. If so, it can be determined that the bridge has collapsed when it is detected that a part of the bridge is missing compared to the reference image of the bridge. Various other events can be detected, and these can be realized by known image processing techniques such as pattern matching.

  When an abnormal event is detected in S2, the image and the type information of the detected event are transmitted to the center station 10 via the wireless line 21 together with the detection time and the terminal station ID (S3). Here, we will also send images, but only send information with a small amount of data, such as event type information, time information, terminal station ID, etc., which are the minimum necessary to create a text for loudspeaker broadcasting. It is good.

  When receiving the information, the center station 10 inputs the information to the center station control unit 201 in the console 2. Then, the loudspeaker broadcast text generation function 201a generates the loudspeaker broadcast text based on the received event information (S4). Here, the operator is made to judge whether or not the loud sound broadcasting is necessary (S5). If it is judged that it is necessary (Yes), the process proceeds to S6, and if it is judged unnecessary (No), the loud sound broadcasting is not performed. The process ends. If it is determined that loudspeaker broadcasting is necessary, the process branches depending on whether or not it is necessary to confirm the content of the text for the loudspeaker broadcast (S6).

In addition, since the configuration and operation of each of the individual receivers 40 (1) to 40 (m) are the same, only one of the individual receivers 40 (1) is given a reference numeral to indicate the configuration. Yes, since the configuration and operation of the monitoring terminal station devices 50 (1) to (l) are the same, only one monitoring terminal station device 50 (1) is denoted by a reference numeral and the configuration is shown.

  Further, in the present embodiment, a case where communication is performed mainly between the center station device 10, the terminal station devices 30 (1) to 30 (n), and the monitoring terminal station devices 50 (1) to (l) will be described. However, for example, the same configuration and operation as the terminal station devices 30 (1) to 30 (n) can be applied to the individual receivers 40 (1) to 40 (m).

  The configuration and operation of the center station apparatus 10 are basically the same as those in the first embodiment, but the terminal station management table 209a of the storage unit 209 has event detection of the monitoring terminal station apparatuses 50 (1) to (l). Status information such as time and time and position data indicating the installation position are also stored together with information of the terminal station devices 30 (1) to 30 (n). Note that state information such as event detection and time is mainly stored when an abnormal event is detected by the camera 55.

  The configuration and operation of the terminal station devices 30 (1) to 30 (n) are the same as those in the first embodiment except that there is no camera, but some of them have a camera installed. Good. When an abnormal event is detected by the camera, the operation is the same as that of the first embodiment. The configurations and operations of the door-to-door receivers 40 (1) to 40 (m) are the same as those in the first embodiment.

  Each of the monitoring terminal station devices 50 (1) to (l) includes a monitoring terminal station control unit 51, a monitoring terminal station radio unit 52, a monitoring terminal station antenna 53, and a terminal station body device 5 that performs radio communication, and an image.

Such a system configuration may be used.

  In the center station 10, when an operator designates a camera from the input unit 207 of the console 2 and requests an image, an image request signal is generated by the center station control unit 201, and the center station via the base station wireless transmission / reception device 1. Radio transmission is performed from the antenna 13. In the monitoring terminal station device 50, when the image request signal is received from the monitoring terminal station antenna 13, the monitoring terminal station control unit 51 receives the image request signal via the wireless unit 52 of the monitoring terminal station body 5 and requests an image from the camera 55. . The camera 55 outputs an image to the monitoring terminal station control unit 51 upon request, and the monitoring terminal station control unit 51 directs the image from the monitoring terminal station antenna 53 to the center station 10 via the monitoring terminal station radio unit 52. Wirelessly transmit. In the center station 10, when an image is received from the center station antenna 13, the control unit 11 receives the image via the wireless unit 12 of the base station wireless transmission / reception device 1 and outputs it to the console 2. In the console 2, the center station control unit 201 outputs the received image to the display unit 208 and the image is displayed on the display unit 208. Thereby, a desired image can be browsed by operation on the center station 10 side.

  The process of acquiring an image in the monitoring terminal station device 50, detecting an abnormal event, and wirelessly transmitting to the center station is the same as the process in the first embodiment.

  Here, a radio communication method in a radio communication system which is an embodiment of the information communication system of the present invention will be described with reference to FIG. Here, the process from detecting an abnormal event with the camera to implementing the loudspeaker will be described.

  The camera 55 installed in the monitoring terminal station apparatus 50 captures the monitoring area, and acquires an image by converting incident light into an electrical signal by the image acquisition unit 56 (S1). The acquired image is subjected to image processing by the image processing unit 57, and the presence or absence of an abnormal event is determined (S2). If an abnormal event is detected (Yes), the process proceeds to S3. If no abnormal event is detected (No), the process of S1 is repeated.

  When an abnormal event is detected in S2, the image and the type information of the detected event are transmitted to the center station 10 through the wireless line 24 together with the detection time and the monitoring terminal station ID (S3). Here, an image is also transmitted, but only information with a small amount of data such as event information may be transmitted.

  When receiving the information, the center station 10 inputs the information to the center station control unit 201 in the console 2. Then, the loudspeaker broadcast text generation function 201a generates a loudspeaker broadcast text based on the received event information (S4). Here, the operator is made to judge whether or not the loud sound broadcasting is necessary (S5). If it is judged that it is necessary (Yes), the process proceeds to S6, and if it is judged unnecessary (No), the loud sound broadcasting is not performed. The process ends. If it is determined that loudspeaker broadcasting is necessary, the process branches depending on whether or not it is necessary to confirm the content of the text for the loudspeaker broadcast (S6). If the confirmation is not necessary (No), the process proceeds to S9 and the voice broadcast is automatically performed. If confirmation is required (Yes), the process proceeds to S7.

  When the setting requires confirmation, the operator confirms the loudspeaker broadcast text displayed on the display unit 208 (S7). If correction is necessary (Yes), the process proceeds to S8, and correction is not necessary. In (No), a loudspeaker broadcast start operation is input by the operator, and the process proceeds to S9. If the voice broadcast text needs to be corrected, the operator corrects the voice broadcast text using the input unit 207 (S8), inputs the voice broadcast start operation, and proceeds to the process of S9. At this time, the terminal station device 30 and / or the door-to-door receiver 40 to be broadcasted by the operator's operation is designated, or all the terminal station devices 30 and / or the door-to-door receiver 40 are designated or set in advance. You may keep it.

  In S9, the text for the loudspeak broadcast is converted into the voice for the loudspeak broadcast (S9). The converted voice for voice broadcasting is transmitted to the designated or all the terminal stations 30 and / or the individual receivers 40 (S10).

  When the terminal station device 30 receives the sound for the loudspeaker broadcasting, the terminal station device 30 broadcasts the sound for the loudspeaker broadcast from the trumpet speaker 34 (S11). Further, when receiving the audio data for the loudspeaker broadcasting, the door-to-side receiver 40 outputs the sound for the loudspeaker broadcast from its own speaker.

  In the determination of S5, the operator determines whether or not the loudspeaker broadcasting is necessary. However, the center station control unit 201 may automatically determine the event, and in that case, the event table 209b displays the event. The center station control unit 201 refers to the event table 209b of the storage unit 209 and makes a determination according to the setting of whether or not the sound broadcast is necessary.

  As described in detail above, according to the present embodiment, an abnormal event is detected by a camera installed in the monitoring terminal station device, and the text and voice for loudspeak broadcasting are automatically generated. The residents can be informed of dangers faster.

  In the above-described two embodiments, the generation of the text and voice for the loudspeaking broadcast is automatically executed. However, it is generated after receiving the voice generation operation for the loudspeaking broadcast from the input unit. Also good.

  Moreover, the abnormal event was detected by performing image processing on the image acquired by the camera and the text was generated. However, the present invention is not limited to this. For example, the abnormal event is detected from the information of a sensor such as a rain gauge. Also good.

  In FIG. 5, the monitoring center station device 60, the monitoring terminal station devices 70 (1) to 70 (p), and the broadcasting terminal station devices 80 (1) to 80 (q) are respectively connected via a network. . The network may be wired or wireless. Although not shown, an image recording apparatus is often connected to the network, and records an image acquired by a camera or distributes a requested recorded video.

  The monitoring center station device 60 includes a monitoring center station control unit 601 including a CPU and a memory for storing an operation program of the monitoring center station device 60, and the monitoring center station control unit 601 is connected to a storage unit 609 and an interface group. Has been. The interface group includes an output interface 602, an input interface 604, a display interface 606, and a network interface 610.

  The monitoring center station control unit 601 includes a loudspeak broadcast text generation function 601a and a voice conversion function 601b. All of these control functions are realized by causing the CPU to execute application programs stored in a program memory (not shown).

  Each of the monitoring terminal station devices 70 (1) to 70 (p) includes an image acquisition unit 71 including an image sensor such as a CCD that acquires an image, an image processing unit 72 that detects an abnormal event by image processing, and a network. And a network interface 73 that transmits and receives signals to and from the connected device.

  Broadcast terminal station apparatuses 80 (1) to 80 (q) are network interfaces that transmit and receive signals between a speaker 81 that reads received voice for loudspeaker broadcasting and loudspeaks and broadcasts it as voice, and a device connected to the network. 82.

  Here, in the present embodiment, a plurality of monitoring terminal station devices 70 (1) to 70 (p) and a plurality of broadcasting terminal station devices 80 (1) to 80 (q) are provided for the monitoring center station device 60. A system configuration directly connected via network lines 61 to 23 is shown. For example, a relay station device is provided, and a monitoring center station device 60 and a plurality of monitoring terminal station devices 70 (1) to 70 (p) Alternatively, a system configuration in which a plurality of broadcasting terminal station devices 80 (1) to 80 (q) are connected via a relay station device may be used.

  The monitoring center station 60 will be described in detail. The output interface 602 converts the audio signal generated by the center station control unit 601 into an analog signal and outputs the sound from the speaker 603. A microphone 605 and an input unit 607 are connected to the input interface 604. The input interface 604 converts the voice of the system administrator input from the microphone 605 and the operation information input from the input unit 607 into a digital signal and outputs the digital signal to the monitoring center station control unit 601. The display interface 606 displays the display data output from the monitoring center station control unit 601 on the display unit 608. For the display unit 608, for example, a display device such as an LCD is used. The network interface 610 transmits and receives signals to and from devices connected to the network under the control of the center station control unit 601.

  The storage unit 609 stores a terminal station management table 609a, an event table 609b, and audio data 609c. In the terminal station management table 609a, data representing a change in state of the terminal station, its time, and position data representing the installation position of the terminal station are stored in association with the ID of the terminal station belonging to this system. The position data is represented by, for example, latitude and longitude, the name of the facility to be monitored, the floor name, the room name, the district name, and the like.

  Upon receiving the event information detected by the monitoring terminal station 70 transmitted from the monitoring terminal station device 70, the voice broadcast text generation function 601a extracts the event type, the occurrence time, and the terminal station ID, and the terminal station management table 609a. And text for loudspeak broadcasting is generated from the information. At this time, the monitoring center station control unit 601 refers to the terminal station management table 609a and the event table 609b in the storage unit 609, and for example, incorporates time and place information into a text fixed sentence according to the event, and the text for the loudspeaker broadcasting Is displayed on the display unit 608 together with an image or the like. The text generated at this time is, for example, “I found an intruder at the front door around XX hours.” “A fire broke out from the conference room around XX hours. Evacuated quickly. "A suspicious object was found in the A corridor on the 2nd floor of the □ building around XX hours and minutes." Here, the location information may store the address of the location where the monitoring terminal station 70 is installed, or the name of the facility to be monitored, the name of the floor, the name of the room, the name of the district, etc. are stored, and these information are extracted. To be converted into text.

  The voice conversion function 601b converts the loudspeak broadcast text generated by the above-described loudspeak broadcast text generation function 601a into the voice for the loudspeak broadcast. At this time, the monitoring center station control unit 601 refers to the voice data 609c in the storage unit 609 and generates a voice corresponding to the text. For example, the voice corresponding to the fixed sentence may be stored, and the voice of time or place may be generated by connecting the voice of each character, or may be generated by connecting the voices of all characters. In the case of an image monitoring system, when an abnormal event transmitted from the monitoring terminal station device 70 is received and a text and voice for loudspeak broadcasting are generated, it is preferable to first output the sound from the speaker 603 and notify the supervisor.

  The text for the loudspeaker broadcast generated by the text generation function for the loudspeaker broadcast 601a or the voice for the loudspeaker broadcast generated by the voice conversion function 601b is regenerated according to the correction content when the correction instruction from the input unit 607 is received. The

  When an instruction for loudspeak broadcasting is given from the input unit 607, the sound for loudspeak broadcast is transmitted to the broadcast terminal station apparatus 80 designated by the network I / F 610 or all of them. When the broadcast terminal station apparatus 80 receives the sound for the loudspeak broadcast, the loudspeak broadcast sound is loudspeaked from the speaker 81.

  A communication method of the image monitoring system which is an embodiment of the information communication system of the present invention will be described with reference to FIG. Here, the process from the detection of the abnormal event by the monitoring terminal station device 70 to the execution of the loudspeaker broadcasting will be described.

  In the monitoring terminal station apparatus 70, a monitoring area is photographed, and an image is acquired by converting incident light into an electrical signal by the image acquisition unit 71 (S21). The acquired image is subjected to image processing by the image processing unit 72, and the presence or absence of an abnormal event is determined (S22). If an abnormal event is detected (Yes), the process proceeds to S23. If no abnormal event is detected (No), the process of S21 is repeated.

  Here, the determination of the abnormal event in S22 will be described. For example, if it is an intruder, it can be judged as an intruder if a new moving object is detected by comparing the acquired image with a reference image acquired in advance, and if it is a suspicious object, the acquired image is stored in advance. When a new object that does not move for a predetermined time compared with the acquired reference image is detected, it can be determined as a left object. Various other events can be detected, and these can be realized by known image processing techniques such as pattern matching.

  When an abnormal event is detected in S22, the image and the type information of the detected event are transmitted to the monitoring center station device 60 via the network together with the detection time and the terminal station ID (S23). In the image monitoring system, an image is basically transmitted, but only information with a small amount of data such as event information may be transmitted.

  Upon receiving these pieces of information, the monitoring center station device 60 inputs the information to the monitoring center station control unit 601. Then, the voice broadcast text generation function 601a and the voice conversion function 601b generate the voice broadcast text and voice based on the received event information, and output the voice from the speaker 81 (S24). Here, the operator is made to judge whether or not the loud sound broadcasting is necessary (S25). When it is judged that it is necessary (Yes), the process proceeds to S26, and when it is judged unnecessary (No), the loud sound broadcasting is not performed. The process ends. If it is determined that loudspeaker broadcasting is necessary, the process branches depending on whether or not it is necessary to confirm the content of the text for the loudspeaker broadcast (S26). If the confirmation is not necessary (No), the process proceeds to S29 and the loudspeaker is automatically broadcast. If confirmation is required (Yes), the process proceeds to S27.

  When the setting requires confirmation, the operator confirms the loudspeaker broadcast text displayed on the display unit 608 (S27). If correction is necessary (Yes), the process proceeds to S28, and correction is not necessary. In (No), a loudspeaker broadcast start operation is input by the operator, and the process proceeds to S29. When the voice broadcast text needs to be corrected, the operator corrects the voice broadcast text using the input unit 607 (S28), inputs the voice broadcast start operation, and proceeds to the processing of S29. At this time, the broadcast terminal station device 80 for performing the loud-speaking broadcast may be designated, or the entire broadcast terminal station device 80 may be designated, or may be set in advance by the operator's operation.

  In S29, the voice conversion function 601b converts the text for the loudspeaker broadcast into the voice for the loudspeaker broadcast (S29). The converted voice for voice broadcasting transmits the voice data for voice broadcasting to the designated or all broadcasting terminal station devices 80 (S30).

  And the broadcast terminal station apparatus 80 will carry out louding broadcasting of the sound for loudspeaking broadcasting from the speaker 34, if the sound for loudspeaking broadcasting is received (S31).

  In the determination of S25, the operator determines whether or not the loudspeaker broadcasting is necessary. However, the monitoring center station control unit 601 may automatically determine, and in that case, the event table 609b stores the determination result. Whether or not the loudspeaker broadcast is necessary is set for each event, and the monitoring center station control unit 601 refers to the event table 609b of the storage unit 609 and determines according to the setting of the necessity or nonexistence of the loudspeaker broadcast.

  As described in detail above, according to the present embodiment, an abnormal event is detected by the monitoring terminal station, and the text and voice for the loudspeak broadcast are automatically generated. Can be informed.

(Third embodiment)
An embodiment according to the present invention will be described with reference to FIG. In the present embodiment, a case will be described in which voice data is created directly without creating text data for loudspeaker broadcasting based on information on an event detected in a terminal station device.

  The camera 35 installed in the terminal station device 30 captures an image of the monitored area, and the image acquisition unit 36 converts the incident light into an electrical signal (S41). The acquired image is subjected to image processing by the image processing unit 37, and the presence or absence of an abnormal event is determined (S42). If an abnormal event is detected (Yes), the process proceeds to S43. If no abnormal event is detected (No), the process of S41 is repeated.

  If an abnormal event is detected in S42, the image and the type information of the detected event are transmitted to the center station 10 through the wireless line 21 together with the detection time and the terminal station ID (S43). Here, we will also send images, but only send information with a small amount of data, such as event type information, time information, terminal station ID, etc., which are the minimum necessary to create a text for loudspeaker broadcasting. It is good.

  When receiving the information, the center station 10 inputs the information to the center station control unit 201 in the console 2. Then, by using the sound generation function for the sound broadcast (not shown), sound data for the sound broadcast is generated based on the received event information (S44), and the converted sound data for the sound broadcast is designated or all To the terminal station 30 and / or the individual receiver 40 (S45). When the terminal station device 30 receives the sound data for the loudspeaker broadcast, the terminal station device 30 broadcasts the sound for the loudspeaker broadcast from the trumpet speaker 34 (S46). Further, when receiving the audio data for the loudspeaker broadcasting, the door-to-side receiver 40 outputs the sound for the loudspeaker broadcast from its own speaker.

  According to the present embodiment, when an abnormal event is detected by the terminal station device or the monitoring terminal station, the center station or the monitoring center station can automatically generate the voice for the loudspeaker broadcast and can perform the loudspeaker broadcast. Can inform about abnormal situations.

(Fourth embodiment)
An embodiment according to the present invention will be described with reference to FIG. In the present embodiment, text data for loudspeak broadcasting is created based on information on an event detected by the terminal station device, and transmitted to a staff terminal registered in advance.

  The camera 35 installed in the terminal station apparatus 30 captures an image by photographing a monitoring area and converting incident light into an electrical signal by the image acquisition unit 36 (S51). The acquired image is subjected to image processing by the image processing unit 37, and the presence or absence of an abnormal event is determined (S52). If an abnormal event is detected (Yes), the process proceeds to S53. If no abnormal event is detected (No), the process of S51 is repeated.

  If an abnormal event is detected in S52, the image and the type information of the detected event are transmitted to the center station 10 via the wireless line 21 together with the detection time and the terminal station ID (S53). Here, we will also send images, but only send information with a small amount of data, such as event type information, time information, terminal station ID, etc., which are the minimum necessary to create a text for loudspeaker broadcasting. It is good.

  When receiving the information, the center station 10 inputs the information to the center station control unit 201 in the console 2. Then, the loudspeaker broadcast text generation function 201a generates a loudspeaker broadcast text based on the received event information (S54). The generated voice broadcast text data is transmitted to a registered staff terminal (for example, a mobile phone, a personal computer, or other dedicated terminal, not shown) by a sending function (not shown) such as e-mail. (S55). At this time, if there is an image received on the center station 10 side, it may be transmitted to the staff terminal.

  When the staff terminal receives the text data information for the loudspeaker broadcast, the text data for the loudspeaker broadcast is displayed on the screen as a character string and edited as necessary. At the same time, a check box for selecting whether or not loud sound broadcasting is necessary and a code input field are also displayed, and information on the necessity of loud sound broadcasting is generated based on the input of the staff. The text data for the loudspeaker broadcast is returned to the center station 10 together with information on the necessity of the loudspeaker broadcast with the original content after the modification if it is modified (S56).

  When the center station 10 receives the data returned from the staff terminal (S57), based on the information on the necessity of the loudspeaker broadcast, if the loudspeaker broadcast is "necessary" (Yes), the received text data for the loudspeaker broadcast Is converted to voice data (S59), and the voice data for the loudspeak broadcast is transmitted to the designated or all the terminal stations 30 and / or the individual receivers 40 (S60). On the other hand, if the broadcast is “No” (No), the process ends without performing the broadcast.

  When the terminal station device 30 receives the sound for the loudspeaker broadcast, the terminal station device 30 broadcasts the sound for the loudspeaker broadcast from the trumpet speaker 34 (S11).

  In this embodiment, the text data for the loudspeak broadcast is transmitted by e-mail, but the URL of the dedicated site may be transmitted so that the text can be corrected and the broadcast instruction can be operated on the dedicated site. . It is also possible to automatically make a call, output the contents for the loudspeaker broadcast as sound, and determine whether the loudspeaker broadcast is necessary by dialing from the staff's mobile phone.

  Also, in this embodiment, it is left to the staff's operation to determine whether or not loudspeaker broadcasting is necessary, but assuming that the staff cannot respond immediately, the staff will respond within a predetermined time (for example, 5 minutes). If the instruction is not accepted, the loudspeaker broadcast may be automatically started with the created content. On the other hand, if the instruction from the staff is not received within a predetermined time, the broadcast may not be performed, and it is better that the operator sets in advance whether to broadcast automatically. .

  As described in detail above, according to the present embodiment, an abnormal event is detected by the monitoring terminal station, and by sending a voice broadcast text to the staff, the staff in charge is absent from work hours, etc. Even in such a case, the occurrence of the abnormal event can be confirmed remotely, and the voice broadcast can be instructed remotely, so that the abnormal event can be dealt with regardless of time and place.

  In each of the embodiments described above, when an event is detected in the terminal station device, an image and event information (type information, time information, and terminal station ID) are transmitted to the center station device. However, for example, only the event information may be transmitted, and the loudspeak broadcast data may be created without displaying an image.

  In addition, when the camera is a pivotable camera such as a pan head-integrated camera, usually, a plurality of predetermined points called preset operations are operated cyclically based on time, etc. The location information is acquired by registering the target and location being imaged for each preset position in advance or by identifying the location by comparing the map information with the camera location information, orientation and zoom ratio, and more detailed location Information may be transmitted to the center station apparatus side.

  Also, in the case of a system that transmits text data from the center station device to the terminal station device, and converts the text data received at the terminal station device into a voice-enhanced broadcast, the text created based on the event information in the center station device Data may be transmitted to the terminal station apparatus, and voice conversion may be performed at the terminal station apparatus for voice conversion.

  In the case of a system that sends text data from the center station device to the individual receiver and displays the text data received at the individual receiver as characters, or converts the voice and outputs it as a loud voice, The text data created based on the information is transmitted to the door-to-door receiver, and the door-to-door receiver displays the text data for the loudspeaker broadcast as characters on the display unit, or the voice data is converted and broadcasted. Good.

  As mentioned above, although this invention has been demonstrated using several embodiment, it is not limited to these embodiment. For example, the image processing function for detecting an abnormal event is provided in the camera in the present embodiment, but an image processing device separate from the camera may be provided, or may be provided on the monitoring center side. . In addition, the text generation function and the voice conversion function may be provided in the same medium, or may be provided in different media.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be deleted from all the components shown in each embodiment. Furthermore, you may combine suitably the component covering different embodiment.
