(Embodiment)
A configuration of a monitoring camera control apparatus according to an embodiment of the present invention and a monitoring camera system using the same will be described with reference to FIG. FIG. 1 is a diagram illustrating a surveillance camera system according to an embodiment of the present invention.

  As shown in FIG. 1, the surveillance camera system 1 is connected to a plurality of surveillance cameras 2 (2a to 2d), a surveillance camera control device 3 that controls the surveillance camera 2, and the surveillance camera control device 3, and displays an image. And a monitor 4.

  The monitoring cameras 2a to 2c and the monitoring camera control device 3 communicate with each other via the Internet 5 which is one of telecommunication lines. The monitoring cameras 2a and 2c and the Internet 5 are connected via a router (not shown) with a cable such as 100BASE-T, and the monitoring camera 2b and the Internet 5 are connected via a wireless access spot (not shown) provided on the Internet 5. Connected wirelessly. The monitoring camera 2d and the monitoring camera control device 3 are directly connected by 100BASE-T or USB (Universal Serial Bus). These connection methods can be appropriately determined depending on the installation location of the monitoring camera 2 and the distance between the monitoring camera 2 and the monitoring camera control device 3.

  The monitoring cameras 2a to 2d are installed so as to monitor the respective ranges of the monitoring areas A to D on roads such as shopping streets and sites such as facilities. The number of surveillance cameras 2 installed can be determined according to the size of the monitored range, but is limited to the number to which the surveillance camera control device 3 can be connected.

  The monitoring camera 2 includes a detection sensor using sound waves, and can detect that the moving body has entered the monitoring area that is the reachable range thereof. Since this detection sensor is simple, it can detect that the moving body has entered, but cannot detect the distance and direction. Information that the detection sensor detects the moving body is transmitted to the monitoring camera control device 3.

  The surveillance camera 2 also has a zoom function for zooming in and out to adjust the viewing angle of the lens, and a pan function and a tilt function for adjusting the direction of the lens.

  The monitoring camera control device 3 displays the image data transmitted by the monitoring cameras 2 a to 2 d directly or via the Internet 5 on the monitor 4. In this display, the image data transmitted from any of the monitoring cameras 2a to 2d can be displayed on the entire screen of the monitor 4, or for example, the screen can be divided into four and displayed simultaneously for four devices. The monitoring camera control device 3 transmits to the monitoring camera 2 a control command for controlling a zoom function for adjusting the viewing angle of the lens, a zoom function for performing zoom-in and zoom-out, and a pan function and a tilt function for adjusting the lens direction. It has a function to do.

  The operation of the surveillance camera system according to the embodiment of the present invention configured as described above will be described with reference to FIG. FIG. 2 is a diagram for explaining the operation of the surveillance camera system according to the embodiment of the present invention.

  As shown in FIG. 2, it is assumed that a suspicious person M as a moving object has entered the monitoring area D. When the detection sensor provided in the monitoring camera 2d detects the suspicious person M, the detection information, which is information indicating that the detection sensor has detected the moving body, is transmitted to the monitoring camera control device 3.

  When the monitoring camera control device 3 receives this detection information, when the transmission source is the monitoring camera 2d, the monitoring camera control device 3 performs a zoom-out operation to the non-detecting monitoring cameras 2a to 2c other than the monitoring camera 2d detected by the detection sensor. Control command to be sent. Thereby, since the viewing angle of the non-detected monitoring cameras 2a to 2c can be widened, each of the monitoring cameras 2a to 2c can capture the suspicious person M as an image. Therefore, the suspicious person M can be captured in the video even by the monitoring cameras 2a to 2c located at a position away from the suspicious person M.

  The monitoring camera control device 3 transmits a control command for performing a zoom-out operation to the non-detected monitoring cameras 2a to 2c, and transmits a control command for performing a zoom-in operation to the monitoring camera 2d detected by the detection sensor. . As a result, the surveillance camera 2d closest to the suspicious person M can magnify and shoot the suspicious person M, so that the face and characteristics of the suspicious person M can be captured in the video.

  Next, a surveillance camera system according to another embodiment of the present invention will be described with reference to FIGS. 3 and 4 are diagrams for explaining a surveillance camera system according to another embodiment of the present invention. 3 and 4, the same components as those in FIGS. 1 and 2 are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 3, it is assumed that a suspicious person M as a moving object has entered the monitoring area D. When the detection sensor provided in the monitoring camera 2d detects the suspicious person M, the detection information is transmitted to the monitoring camera control device 3.

  When the monitoring camera control device 3 receives this detection information, when the transmission source is the monitoring camera 2d, the monitoring camera control device 3 performs a zoom-in operation on the non-detecting monitoring cameras 2a to 2c other than the monitoring camera 2d detected by the detection sensor. Together with the control command, the detection sensor transmits a control command for directing the lens in the direction of the monitoring camera 2d that detected the suspicious person M.

  The detection sensor can detect the presence of the suspicious person M as described above, but cannot accurately grasp the direction and distance. Accordingly, when any of the monitoring cameras 2 detects a moving body, the non-detected monitoring cameras 2 are monitored in advance in which direction and to what extent the lens is panned or tilted. By setting the camera control device 3 in advance, the lens orientation of the non-detected surveillance camera 2 can be accurately controlled. In other words, the inexpensive surveillance camera 2 provided with a detection sensor that can detect the presence of the moving body but cannot measure the direction and distance thereof can accurately point the lens in that direction.

  As described above, even when the undetected surveillance cameras 2a to 2c are separated from the suspicious person, the camera can be enlarged and zoomed in by the zoom-in operation, and the direction of the lens is the surveillance camera 2d that has detected the suspicious person M. Therefore, the supervisor can grasp the state and behavior of the suspicious person M in more detail.

  In addition, the monitoring camera control device 3 transmits a control command for performing a zoom-in operation to the monitoring camera 2d detected by the detection sensor. As a result, the surveillance camera 2d closest to the suspicious person M can magnify and shoot the suspicious person M, so that the face and characteristics of the suspicious person M can be captured in the video. That is, by directing all the surveillance cameras 2 capable of capturing the suspicious person M to the suspicious person M, the suspicious person M can be enlarged and captured from various angles.

  As shown in FIG. 4, it is assumed that the suspicious person M next moves in the traveling direction F and enters the monitoring area C. When the suspicious person M enters the monitoring area C, the detection sensor of the monitoring camera 2c detects the suspicious person M. The monitoring camera 2c transmits the detection information to the monitoring camera control device 3. When the monitoring camera 2c detects the suspicious person M, the monitoring camera control device 3 does not execute the control command for directing the lens toward the monitoring camera 2c in which the detection sensor detects the suspicious person M and the control command for performing the zoom-in operation. It transmits to the monitoring camera 2a, 2b, 2d of a detection.

And the surveillance camera control apparatus 3 transmits the control command which performs a zoom-in operation to the detected surveillance camera 2c. Furthermore, the monitoring camera control device 3 sends a control command to the monitoring camera 2c so that the direction of the lens facing the monitoring area D direction, which is the direction of the monitoring camera 2d before the detection, faces the lens toward the monitoring area C. Send.

  As described above, the surveillance camera control device 3 captures the suspicious person M in the image by causing the surveillance camera 2 that has not detected the suspicious person M to perform a zoom-in operation or a zoom-out operation. However, whether to select the zoom-in operation or the zoom-out operation can be selected by the monitoring camera control device 3 by setting, and is determined as appropriate according to the size of the range to be monitored and the purpose of use. It is possible.

  When a suspicious person enters the surveillance area, the present invention can easily capture the suspicious person as an image even with a surveillance camera located away from the intruder. This is suitable for a monitoring camera control device that controls a monitoring camera.
