Abstract
Description
[Technical Field]
[0001] The present invention relates to a broadcasting system equipped with a surveillance camera with a speaker. [Background technology]
[0002] In recent years, an increasing number of regions have been installing security surveillance cameras outdoors to prevent crimes, etc., and the applicant has already proposed a standalone security surveillance camera for use outdoors (Patent Document 1: Patent No. 5698104). The above-mentioned stand-alone type security surveillance cameras can be installed anywhere because they can secure their own power source, and therefore the number of such cameras being installed is increasing dramatically. Meanwhile, disaster prevention speakers are being installed to notify local residents and others of disaster occurrence information, evacuation information, and the like in the event of a disaster. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent No. 5698104 Summary of the Invention [Problem to be solved by the invention]
[0004] The inventors noticed that in the event of a disaster, it would be advantageous to combine security surveillance cameras, the number of which is increasing, with disaster prevention speakers in order to more accurately ascertain the situation at the time of the disaster and to inform residents in necessary areas of appropriate disaster occurrence information and evacuation information, etc., by checking the situation at the time of the disaster and accurately grasping the situation at the time of the disaster through images, and informing necessary areas of the situation at the time of the disaster and evacuation information, etc. However, as mentioned above, while the number of security surveillance cameras installed has been increasing in recent years, the number of disaster prevention speakers installed has not, and because security surveillance cameras and disaster prevention speakers are installed without any relationship between them, even if the security surveillance cameras can accurately grasp the situation of a disaster, disaster prevention speakers are not necessarily installed in areas where they are needed, resulting in the problem that disaster occurrence situations and evacuation information cannot be notified to necessary areas. While it is possible to notify a wider area of disaster occurrence situations and evacuation information by increasing the volume of the disaster prevention speakers, if the volume is turned up too high, problems such as the sound distorting and being difficult to hear can occur. Furthermore, since a disaster occurring in one area may cause damage to other areas after some time has passed, even if disaster prevention speakers are installed in areas where security surveillance cameras are installed, if disaster prevention speakers are not installed in other areas where disasters can be predicted to occur, it cannot be said that disaster situations and evacuation information can be communicated to areas that need it. The above-mentioned problems apply not only to disasters but also to crime prevention. The present invention aims to solve the above-mentioned problems and to provide a broadcasting system that uses a surveillance camera equipped with a speaker to enable information on disaster prevention and crime prevention to be confirmed in images, and that reliably disseminates the information on disaster prevention and crime prevention to necessary areas using the speaker installed in the surveillance camera.

[Brief explanation of the drawings]
[0007] [Figure 1] 1 is a schematic system diagram of a broadcasting system including a surveillance camera with a speaker according to the present invention; [Figure 2] 1 is a schematic block diagram of a surveillance camera with a speaker. [Figure 3] 1 is a flowchart showing a method of using a broadcasting system including a surveillance camera with a speaker according to the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0008] Hereinafter, an embodiment of a broadcasting system including a monitoring camera with a speaker according to the present invention will be described with reference to the accompanying drawings. An embodiment of a broadcasting system including a monitoring camera with a speaker according to the present invention (hereinafter simply referred to as a "broadcasting system") will be described below with reference to FIGS. In this embodiment, the broadcasting system according to the present invention is used as a disaster and crime prevention broadcasting system used for disaster prevention and crime prevention. As shown in the drawing, this broadcasting system includes a plurality of monitoring cameras 1 with speakers and one or more terminal devices 10.
[0009] As shown in Fig. 2, the speaker-equipped surveillance camera 1 includes an IP camera 2, an IP remote broadcasting device 3, an amplifier 4, and a speaker 5, is wired to an LTE router 6, and is wirelessly connected to an LTE communication network via a communication antenna 7 provided on the LTE router 6. The speaker-equipped surveillance camera 1 may be configured to be powered by a built-in battery (not shown), or may be configured to be powered by an AC 100V power source in locations where a power source is available, such as from a utility pole. Furthermore, the speaker-equipped surveillance camera 1 may be equipped with a solar panel (not shown), and if equipped with a solar panel, the battery may be configured to be rechargeable via the solar panel. Furthermore, the LTE router 6 and communication antenna 7 may be built into the speaker-equipped surveillance camera 1, or may be configured separately from the speaker-equipped surveillance camera 1. In the embodiment of Fig. 1, the LTE router 6 is configured separately from the speaker-equipped surveillance camera 1, and the speaker-equipped surveillance cameras 1a to 1d and 1g are connected to the LTE routers 6a to 6d and 6f, respectively, and the speaker-equipped surveillance cameras 1e and 1f are connected to the LTE router 6e. Each speaker-equipped surveillance camera 1 is assigned unique camera identification information, specifically a fixed IP address, and a global IP address is assigned to each LTE router 6. This allows the terminal device 10 to communicate with the speaker-equipped surveillance camera 1 connected to the LTE router 6 via the LTE communication network by registering the global IP address of the LTE router 6 in each terminal device 10.
[0010] The terminal device 10 consists of, for example, a smartphone or a personal computer configured to be connectable to an LTE communication network, and is configured to install dedicated software so that images captured by the IP camera 2 of any speaker-equipped surveillance camera 1 that constitutes the broadcasting system can be viewed, and audio information can be output from the speaker 5 of any speaker-equipped surveillance camera 1. The terminal device 10 and the IP camera 2 of the speaker-equipped surveillance camera 1 are connected by P2P communication via the LTE communication network, and the terminal device 10 and the speaker 5 are connected via the LTE communication network using VOIP (Voice over Internet Protocol). Specifically, audio data output from the terminal device 10 to the speaker 4 of a specific speaker-equipped surveillance camera 1 is converted into an audio signal in the IP remote broadcasting device 3, amplified by the amplifier 4, and output from the speaker 5. The maximum output of the speaker 5 is desirably a high volume in order to deliver audio information over as wide a range as possible, and in this embodiment, this can be 108 dB. Furthermore, the IP remote broadcasting device 3 is normally powered off and is configured to be powered on when a trigger signal is input from the terminal device 10, thereby minimizing battery consumption when the speaker-equipped surveillance camera 1 is battery-powered. Furthermore, the dedicated software installed in the terminal device 10 is configured to pre-register the global IP address of the LTE router 6 and the camera identification information (in this embodiment, fixed IP address) of the speaker-equipped surveillance camera 1 connected to the LTE router 6, and to register installation location information regarding the location where each speaker-equipped surveillance camera 1 is installed in association with the camera identification information of the corresponding speaker-equipped surveillance camera 1.
[0011] Furthermore, the dedicated software is configured to be able to store the camera identification information of each speaker-equipped surveillance camera 1 in association with area identification information relating to the area in which each speaker-equipped surveillance camera 1 is installed. Specifically, the area identification information is determined based on the area where disaster occurrence information, evacuation information, etc. should be broadcast simultaneously in the event of a disaster, etc., and is determined based on, for example, addresses, surrounding environments, etc. In the embodiment of Fig. 1, two areas A1 and A2 are set based on addresses, and the camera identification information of speaker-equipped monitoring cameras 1a to 1c included in area A1 is stored in association with the area identification information of area A1, and the camera identification information of speaker-equipped monitoring cameras 1d to 1g included in area A2 is stored in association with the area identification information of area A2.
[0012] In addition, in the embodiment of Figure 1, an area B is set based on the surrounding environment of a riverside, and the camera identification information of the speaker-equipped surveillance cameras 1a and 1d included in the riverside area B is also stored in association with the area identification information of area B. As described above, the area identification information can be set arbitrarily based on the area in which disaster occurrence information, evacuation information, etc. should be broadcast simultaneously in the event of a disaster, and the camera identification information of a surveillance camera with a speaker can be associated across multiple area identification information. Specifically, for example, in the embodiment of Figure 1, it is also possible to divide riverside area B into an upstream riverside area and a downstream riverside area.By setting it up in this way, for example, if there is a possibility of river flooding from upstream to downstream due to heavy rain or the like, it is possible to first broadcast evacuation information, etc. in the upstream riverside area, broadcast disaster occurrence information in the downstream riverside area, and then broadcast evacuation information to the downstream riverside area depending on the flooding situation.Conversely, if there is a possibility of river flooding from downstream to upstream due to a tsunami or the like, it is possible to first broadcast evacuation information, etc. in the downstream riverside area, broadcast disaster occurrence information in the upstream riverside area, and then broadcast evacuation information to the upstream riverside area depending on the flooding situation.
[0013] The association between the above-mentioned camera identification information and area identification information can of course be set and stored on each individual terminal device, but it is also possible, for example, to store the association data on a server located on the cloud and download the association data to a terminal device and use it as needed, or to upload the association data set on each individual terminal device to a server located on the cloud so that the uploaded data can be used on other terminal devices. The dedicated software installed in the terminal device 10 is configured so that, based on the association data between the camera identification information and the area identification information, the user of the terminal device 10 can select an area where audio information should be output simultaneously, and can simultaneously view images from one or more loudspeaker-equipped surveillance cameras 1 included in that area, select one or more loudspeaker-equipped surveillance cameras 1 that will output audio information based on the viewed images, and can also select a broadcasting method for the selected one or more loudspeaker-equipped surveillance cameras 1 to output the audio information. Specifically, the broadcasting method can be selected between a live voice broadcast that broadcasts audio information input through a microphone (not shown) of the terminal device 10, and a fixed message broadcast that broadcasts a pre-recorded fixed message.
[0014] In addition, the terminal device 10 may have translation software or may communicate with translation software on the Internet. When live voice broadcasting is performed, the voice information input through the microphone of the terminal device 10 may be translated into a required language, and then the voice may be output in the translated language.
[0015] By configuring the terminal device 10 as described above, for example, in the broadcasting system of Figure 1, when there is a high possibility of river flooding due to heavy rain or the like, the user of the terminal device 10 can select riverside area B, check images taken by IP cameras 2 of speaker-equipped surveillance cameras 1a and 1d included in area B, select all speaker-equipped surveillance cameras 1a and 1d included in area B, and then output evacuation information by voice broadcast; and select area A1 which overlaps with riverside area B, check images taken by IP cameras 2 of speaker-equipped surveillance cameras 1a to 1c included in area A1, select speaker-equipped surveillance cameras 1b and 1c excluding speaker-equipped surveillance camera 1a which has already broadcast evacuation information, and output disaster occurrence information; and then select area A2 and output necessary audio information from the necessary speaker-equipped surveillance cameras as needed. In this way, an area where multiple surveillance cameras with speakers are installed is divided into multiple areas based on addresses, surrounding areas, etc., area identification information and camera identification information are associated and stored, and the image captured by IP camera 2 is confirmed based on the associated data, and then Erica and / or the surveillance cameras with speakers included in that area to which audio information should be broadcast can be selected, making it possible to accurately provide the necessary information to the necessary areas by audio.
[0016] An example of a method for operating the broadcasting system in the terminal device 10 in which the dedicated software configured as described above is installed will be specifically described below with reference to the flowchart of FIG. FIG. 3 is a flowchart showing an example of a method for operating the dedicated software. First, the user starts up the dedicated software using the smartphone that constitutes the terminal device 10 (step 1). Next, the user enters the ID and password previously registered in the dedicated software (step 2), and selects the next operation on the initial setup and broadcast destination area selection screen (step 3). In the initial setup, for example, the speaker-equipped surveillance cameras 1 are selected and registered (using camera identification information such as the global IP address of the LTE router or the fixed IP address assigned to each speaker-equipped surveillance camera 1), the installation location information (name) of each speaker-equipped surveillance camera 1 is set, the camera identification information is associated with area information, and a fixed message is recorded. Furthermore, if the association data between the camera identification information and area information is stored in a server provided in the cloud as described above, the association data is selected and downloaded. If the broadcast destination area selection screen is selected in step 3, the terminal device 10 displays the registered area identification information (or the name assigned to each area identification information) (step 4). If the user selects a broadcast area in step 4, the terminal device 10 displays a mode selection screen (step 5). On the mode selection screen, it is possible to select between a broadcast mode, which immediately broadcasts to the selected broadcast area, and a camera mode, which allows the user to check images captured by the IP camera 2 of the speaker-equipped surveillance camera 1 included in the selected broadcast area. When the broadcast mode is selected, the terminal device 10 displays a list of the speaker-equipped surveillance cameras 1 included in the selected broadcast destination area (step 6). When the user selects all or some of the speaker-equipped surveillance cameras 1 in step 6, the terminal device 10 displays a broadcast method selection screen (step 7). On the broadcasting method selection screen, it is possible to select between a live voice broadcasting mode in which voice information input from the microphone of the terminal device 10 is output, and a fixed message broadcasting mode in which a pre-recorded fixed message is output. Depending on the mode selected in step 7, the terminal device 10 outputs the audio information input from the microphone or a pre-recorded standard message to the selected speaker-equipped surveillance camera 1, and the speaker-equipped surveillance camera 1 converts the received audio data into an audio signal using the IP remote broadcasting device 3, then amplifies it using the amplifier 4 and outputs it from the speaker 5. When the camera mode is selected in step 5, the terminal device 10 displays a list of the speaker-equipped surveillance cameras 1 included in the selected broadcast destination area, and the user can select to display images captured by the IP cameras 2 of all or some of the speaker-equipped surveillance cameras 1 (step 8). The user checks the captured image displayed in step 8 and decides whether to immediately broadcast audio information from the speaker-equipped surveillance camera 1 selected in step 8, or to reselect the broadcast destination area or a speaker-equipped surveillance camera 1 included in the broadcast destination area (step 9). Specifically, for example, if you select area A1 because of heavy rainfall and check the image, and there are areas in area A1 where flooding has begun, you can reselect area B to check the image to see if the river is overflowing in adjacent area B along the river, and broadcast evacuation information to area B and disaster occurrence information to area A1, or output evacuation information to areas A1 and A2 in addition to area B. When a loudspeaker-equipped monitoring camera 1 that should broadcast audio information is selected in step 9 based on the photographic information viewed in step 8, the terminal device 10 displays a broadcasting method selection screen (step 10). In step 10, when either a live voice broadcasting mode in which voice information input from the microphone of the terminal device 10 is output or a standard message broadcasting mode in which a pre-recorded standard message is output is selected, voice data is output in the selected mode.
[0017] In the above-described embodiment, camera identification information is assigned to the speaker-equipped surveillance camera 1, the area in which the speaker-equipped surveillance camera 1 is installed is divided into multiple areas based on the address, surrounding environment, etc., and area identification information is assigned to each area, the camera identification information and the area identification information are associated and stored, and based on the associated data, it is possible to view images captured by the IP camera and select and decide which speaker-equipped surveillance camera should broadcast audio information, and the user is configured to make judgments about the occurrence of disasters, etc. by referring only to the images. However, this is not limited to this embodiment, and for example, on the screen for selecting the broadcast destination area, it may be configured to display that a weather warning or weather advisory has been issued for the corresponding area based on weather warnings and weather advisories issued by the Japan Meteorological Agency, and further, it may be configured to display the possibility of river flooding, etc., when listing the identification information of the broadcast destination area or each speaker-equipped surveillance camera, using an AI program that predicts river flooding based on time-lapse rainfall information issued by the Japan Meteorological Agency. In the above-described embodiment, the broadcast destination area is set based on the conditions of an address and being along a river, but the area can be set arbitrarily depending on the local environment in which the broadcasting system of the present invention is used, and can be set, for example, to an area along the coast where damage from a tsunami is likely to occur, an area of soil and sand where landslides are likely to occur, or an area along a volcano where damage from a volcanic eruption is likely to occur. Furthermore, the broadcasting system according to the present invention can be used not only for disaster prevention but also for crime prevention. In this case, for example, the broadcast area can be set arbitrarily according to the surrounding environment of a school, etc. For example, it is possible to set an area along the route to and from school for elementary school students. By setting it in this way, for example, if a crime has occurred in the area and the perpetrator is still at large, it is possible to broadcast audio information calling attention to the crime situation, etc., from a surveillance camera 1 with a speaker set on the route to and from school in time to coincide with the time when people are going to and from school.
