Since the configuration of the part is generally known technology, detailed description thereof will be omitted.

The operation of the security monitoring system using the sensor and the camera according to the present invention based on such a configuration will be described with reference to FIGS. 1 to 5 as follows.

First, for the security surveillance operation of the present invention, as shown in Figure 3, a plurality of security monitoring sensors (11-1 ~ 11-16) and a video recording for security surveillance is possible in the place where security surveillance is required. At least one camera 13-1 or 13-2 capable of rotating movement according to the sensor detection signal should be installed. FIG. 3 illustrates a case where a security surveillance system is implemented by installing 16 sensors 11-1 to 11-16 and two cameras 13-1 and 13-2.

When the plurality of sensors 11-1 to 11-16 and the at least one cameras 13-1 and 13-2 are installed in this way, the security monitoring control unit 15 reaches the designated security monitoring time, and the database unit. By accessing the system information storage unit of (10), the overall security monitoring function including the sensor manager 12 and the camera drivers 14-1 and 14-2 is activated (step S21), whereby the sensor manager 12 By driving each sensor (11-1 ~ 11-16) in conjunction with the self to start the detection operation of the movement or sound of the object, the camera driving unit (14-1, 14-2) is linked with itself By driving the cameras 13-1 and 13-2, image capturing for security monitoring is started (step S22).

At this time, the cameras 13-1 and 13-2 driven by the camera driving units 14-1 and 14-2 perform real-time image capturing on a region visible within a predetermined shooting angle. The image information photographed by -1 and 13-2 is transmitted to the security monitoring controller 15 by the camera drivers 14-1 and 14-2 in a wired or wireless manner.

The security monitoring controller 15 collects image information captured by each of the cameras 13-1 and 13-2 and transmitted through the corresponding camera driving units 14-1 and 14-2 and the database unit 10. It stores and manages each camera 13-1 and 13-2 in the video information storage unit, and simultaneously displays the collected video information on at least one monitor screen to provide a security monitoring service (step S23). ).

While the security surveillance service is in progress, each sensor 11-1 to 11-16 installed in a path or location where an outsider is expected to invade performs a certain sensing operation, and the movement or sound of an object within a certain distance. If this is detected, a corresponding detection signal is generated and output to the sensor manager 12.

Then, the sensor management unit 12 confirms whether the sensor detection signal is input from the sensors 11-1 to 11-16 (step S24), and the sensor detection signal from any of the sensors 11-1 to 11-16. When is input, after analyzing the input sensor detection signal to confirm the type of the sensor detection signal (step S25), the information about the type of the sensor detection signal with the sensor identification number to which the detection signal is inputted, the security monitoring control unit ( 15) (step S26).

Subsequently, when the type of the sensor detection signal currently detected from the sensor manager 12 and the sensor identification number to which the detection signal is input are reported, the security monitoring controller 15 accesses and reports the control information storage unit of the database unit 10. After extracting the camera rotation control information corresponding to the type of sensor detection signal and the sensor identification number, and the current photographing direction information of the cameras 13-1 and 13-2 to be rotated, the extracted camera rotation control information and the current The rotation direction and the rotation angle of the cameras 13-1 and 13-2 are calculated based on the camera photographing direction information (step S27).

In this way, after calculating the rotation direction and rotation angle required for camera rotation control, the security monitoring control part 15 uses the calculated camera rotation direction and rotation angle information with the cameras 13-1 and 13-2 which are rotation control objects. The control information of the database unit 10 transmits the current camera photographing direction information according to the rotational movement of the corresponding cameras 13-1 and 13-2 while being transmitted to the interlocking camera drivers 14-1 and 14-2. It will be stored in the storage.

Then, the camera driving units 14-1 and 14-2 are configured according to the camera rotation control of the security monitoring control unit 15, that is, the camera rotation direction and the rotation angle information received from the security monitoring control unit 15. By moving the 1, 13-2 by a certain angle in the up / down / left / right directions, the cameras 13-1, 13 are moved in the direction in which the movement or the sound of the object is detected by the arbitrary sensors 11-1 to 11-16. The photographing direction of -2) is rotated (step S28).

Thereafter, the cameras 13-1 and 13-2 that are rotated and moved like the other cameras perform real-time image capturing on an area visible within a predetermined angle in the direction of rotated movement, and the security monitoring controller 15 performs the step S23. As shown in FIG. 2, the camera collects image information captured by the cameras 13-1 and 13-2 and transmitted through the camera driving units 14-1 and 14-2, so that each camera ( 13-1, 13-2) repeatedly performs a series of operations to store and manage, and at the same time to provide a security monitoring service by displaying the collected image information on at least one monitor screen.

In addition, the security monitoring control unit 15 may generate an alarm in response to the movement of the object or the sound to the administrator. Thus, the cameras 13-1 and 13-2 corresponding to the direction in which the movement or the sound of the object is detected by the sensors 11-1 to 11-16 installed throughout, even if the administrator does not manually operate the camera rotation movement. Automatically rotates and performs a series of video tracking shots to perform efficient security surveillance.

For example, as shown in FIG. 3, the first camera 13-1 photographs an area A and the second camera 13-2 photographs an image of the area D, while the first sensor 11-1 detects an object. When a motion is detected and a corresponding detection signal is generated and output to the sensor manager 12, the sensor manager 12 analyzes the input sensor detection signal and confirms that the type of the sensor detection signal is a motion detection signal. In addition, by reporting the information on the type of the sensor detection signal to the security monitoring control unit 15 with the sensor identification number to which the sensor detection signal is input, security monitoring that the motion detection signal has occurred in the first sensor 11-1 Report to the controller 15.

Subsequently, the security monitoring controller 15 accesses the control information storage unit of the database unit 10 and detects the sensor as the motion detection signal is generated from the sensor 11-1 from the sensor manager 12. The camera rotation control information corresponding to the signal type and the sensor identification number and the current photographing direction information of the camera 14-1 to be rotated are extracted. In this case, the control information storage unit of the database unit 10 includes the following. Assuming the state as shown in Table 1 and Table 2, since the motion detection signal has been reported from the first sensor 11-1, the first camera 13-1 is rotated 70 degrees to the right. The camera rotation control information is extracted, and at the same time, the current photographing direction information of the first camera 13-1, which is the camera to be rotated, is extracted. At this time, the first camera 13-1 extracts the initial photographing direction information since the photographing state of the area A is taken.

The security monitoring controller 15 calculates the camera rotation direction and the rotation angle based on the extracted camera rotation control information and the current camera photographing direction information. At this time, the first camera 13-1 determines the initial photographing direction. Since it is maintained, the camera rotation direction and rotation angle that the first camera 13-1 should be rotated 70 degrees to the right direction are calculated.

At the same time, the current camera photographing direction information according to the rotational movement of the first camera 13-1 is stored in the control information storage unit of the database unit 10.

In addition, the camera driver 14-1 rotates the first camera 13-1 by 70 degrees to the right as shown in FIG. 4, according to the camera rotation control of the security monitoring controller 15. When the movement of the object is detected by -1), an image of the region C in which the first sensor 11-1 is located can be taken.

Also, as shown in FIG. 4, while the first camera 13-1 photographs the region C and the second camera 13-2 photographs the image of the region D, a predetermined sound is output from the second sensor 11-2. When the sensor generates a detection signal corresponding to the detected signal and outputs the detected signal to the sensor manager 12, the sensor manager 12 analyzes the input sensor signal and generates a sound detection signal from the second sensor 11-2. Report to the security monitoring control unit 15, and the security monitoring control unit 15 accesses the control information storage unit of the database unit 10 according to the report that the sound detection signal is generated from the sensor 11-2. Camera rotation control information corresponding to the currently reported sensor detection signal type and sensor identification number and current shooting direction information of the camera to be rotated are extracted, and at this time, the second sensor 11-2 detects a sound detection signal. Is reported to have occurred, The first camera 13-1 rotates by 90 degrees in the right direction and the second camera 13-2 extracts camera rotation control information to rotate by 90 degrees in the left direction. The current photographing direction information of the first camera 13-1 and the second camera 13-2, which are the cameras, is extracted.

The security monitoring controller 15 calculates the camera rotation direction and the rotation angle based on the extracted camera rotation control information and the current camera photographing direction information. At this time, the first camera 13-1 as shown in Table 3 below. ) Is rotated 70 degrees in the right direction to capture the image in the C region, and the second camera 13-2 maintains the initial shooting direction, so the first camera 13-1 is right in the current state.

Thereafter, the security monitoring controller 15 moves the camera rotation direction and the rotation angle information calculated above, that is, the first camera 13-1 rotates 20 degrees to the right in the current state, and the second camera 13-2 moves to the left. Camera rotation control information for rotating the camera 90 degrees in the direction is transmitted to each of the camera drivers 14-1 and 14-2, and at the same time, the first camera 13-1 and the second camera 13-2 are rotated. The current camera photographing direction information according to the movement is stored in the control information storage unit of the database unit 10 as shown in Table 4 below.

Camera number Current shooting direction information One Rotate right by 90 degrees (image recording status for C 'area) 2 Rotate 90 ° to the left (image recording status for E 'area)

Then, the camera driving unit 14-1, 14-2 rotates the first camera 13-1 by 20 degrees to the right as shown in FIG. 5, according to the camera rotation control of the security monitoring controller 15. The first camera 13-2 is rotated 90 degrees in the left direction so that a predetermined sound is detected by the second sensor 11-2, the first camera 13-1 and the second camera 13-2. It is possible to take images of the C 'and E' area around the second sensor 11-2 is located using.

In addition, as shown in FIG. 4, the first camera 13-1 photographs the region C, and the second camera 13-2 photographs the image of the region D while the motion of the object is detected by the third sensor 11-3.
