In this case, the security camera is a security camera that monitors an area where a fire occurrence detector providing a fire occurrence signal is installed, and determines whether the fire occurrence signal is authentic or not based on the image information collected through the security camera.

When the security camera is composed of a thermal imaging camera and a low-illuminance camera, the integrated control server uses a mapping between the optical image data generated by the low-illuminance camera and the thermal image data generated by the thermal imaging camera, A night image improving module (not shown) may be provided.

The night image improvement module is connected to the control module and provides the corrected image data to the control module. At this time, the control module outputs the image data provided from the night image improving module through the display device 200.

As described above, the night image improving module provides an effect of obtaining an image having sharp contours and colors by using the mapping between the optical image data generated by the low-illuminance camera and the thermal image data generated by the thermal imaging camera.

To this end, the night image improving module generates the corrected image data through a process of size adjustment of a subject to be imaged, an image acquisition process, an output image forming process, and an output image storing process.

More specifically, the image-capturing object size adjustment process may be performed by matching one of the low-illuminance camera and the thermal image camera to match the forward viewing angle, or adjusting the forward viewing angle of the low-illuminance camera and the thermal image camera, It is a process of coordinating all of them.

The image acquisition process is performed by collecting an optical image at night with respect to a region to be photographed through a low-illuminance camera equipped with an electronically amplifying CCD so that color images can be photographed in an environment of 1 to 0.2 lux, Is acquired and stored.

The output image forming process includes a matching data extracting step of extracting color data of an object to be photographed from the optical image and extracting contour data of the object to be photographed from the thermal image and digitally synthesizing the color data and the contour data And a digital synthesis process for composing one output image.

The output image storing process is a process of storing an output image generated through the output image forming step.

If such a night image improving module is provided, the integrated security control system according to the present invention can check the authenticity of the fire occurrence signal at night even on the screen of the display device 200. In other words, even if a fire occurs in a building with a light on, it is difficult to grasp a fire situation with a general CCD camera. However, since the integrated security control system of the present invention uses an image captured by a low- It is possible to accurately monitor the fire of the building where the intelligent building system is installed.

Meanwhile, the integrated control server 300 is configured to transmit a control signal for the traffic light and the traffic variable guide board to the traffic control system through the system interface middleware 360 when an event occurrence is detected through the event detection module 310 . In other words, when an event is detected, the administrator of the integrated security control system can output the emergency dispatch guide and the evacuation guidance through the traffic variable guide board and control the traffic light for rapid traffic control.
