On the other hand, the mobile intelligent video surveillance system, which is a component of the mobile intelligent video surveillance system based on the SDN fusion mobile ad-hoc capable of self-powered according to an embodiment of the present invention, further includes an angle adjusting member 40 for direction adjustment from multiple angles. It can be configured. This will be described with reference to FIGS. 6 to 10.

6 is a perspective view of an angle adjustment member according to an embodiment of the present invention, FIG. 7 is an internal configuration diagram viewed by cutting the body of the angle adjustment member of FIG. 6, and FIGS. 8A to 8D illustrate a method of operating the angle adjustment member. It is a view for explaining, and FIG. 9 is an exemplary view of a guide groove cover provided to minimize exposure of the components of the angle adjusting member of FIG. 6, and FIGS. 10A to 10D are cylinders of various diameters or various areas It is an example of the use of a fixture that can be deformed according to the shape of the square pillar of.

At this time, when motion is detected in the image monitoring shaded area (B), the one image monitoring device (10-1) Motion is detected in two places (A, B) in the vicinity, but it is difficult to shoot two places (A, B) with only one video surveillance device (10-1). Video surveillance shadows by adjusting the shooting position to monitor the direction (B) in which the motion is detected by using the video surveillance device (10-2) in which the surrounding motion is not detected among the monitoring devices (10-2 to 10-4). Area (B) can be minimized.

Here, if there are a plurality of video surveillance devices in which the surrounding motion is not detected, a clearer and more accurate image can be obtained by allowing the video surveillance device closest to the one video surveillance device 10-1 to adjust the photographing position.
