Here, when the image collecting device 120 and the image storage device 110 are connected by using a short range wireless communication method, the image collecting device 120 may be manufactured in a portable form.

Meanwhile, when the image collecting device 120 and the image storage device 110 are connected by using a mobile communication method, the image collecting device 120 may be used as a server in a control center.

As such, even when the image collection device 120 and the image storage device 110 are connected by using a mobile communication method, the video surveillance system 100 according to an embodiment of the present invention is similar to a conventional video surveillance system. Instead of delivering real-time images, only the images stored in the image storage device 110 are connected to each other only when they are not normally connected to each other and are transferred to the image collection apparatus 120 through a mobile communication method. Therefore, the communication cost of the conventional zero

Compared to the phase monitoring system, it can be greatly reduced, and there is no need to upgrade the performance of the image capturing apparatus 120, and there is no need to increase the storage capacity.

Meanwhile, the image collecting device 120 may communicate with the image storage device 110 through a wired communication method.

After capturing and storing an image of an area, the image collecting device 120 collects the stored image from the image storage device 110 only when necessary and retrieves the stored image to monitor the surveillance area afterwards.

Therefore, no cable construction is required for network connection, and since the captured image is not transmitted in real time, communication cost can be greatly reduced, and the image storage device 110 for capturing and storing the image is different from the image collection apparatus 120. Since it can be installed independently, there is an advantage that it is very easy to install and is not restricted by the installation site.

On the other hand, since the image storage device 110 for capturing and storing the image of the surveillance area can be arranged independently without a network connection, the image storage device 110 is concentrated in the main surveillance area and then searched for after image.

The collection device 120 may perform communication through a wireless communication method. More preferably, the image storage device 110 and the image collection device 120 may perform communication through a short range wireless communication method.

When the image storage device 110 and the image collection device 120 are connected through communication, an image request signal is generated from the image collection device 120 and transferred to the image storage device 110 (S130).

When the image request signal is transmitted to the image storage device 110, an image stored in the image storage device 110 is transmitted to the image collection device 120 and stored according to the image request signal (S140).

In more detail, when the image request signal is transmitted to the processor (114) of the image storage device 110, the processor 114 collects the image stored in the memory unit 112 by the modem 113 Is transmitted to the image collecting device 120 and stored.

For example, the image collecting device 120 transmits a list and an installation position of the image storage device 110, which is downloaded and stored from the server 131 of the real-time video monitoring device 130, to the navigation to perform the navigation. The installation location and the optimal path of the image storage device 110 can be guided through the moving means such as a vehicle or a drone of the user, and the image stored in the image storage device 110 can be received and stored.

Here, the navigation may be a navigation that is provided in a moving means such as a user vehicle or a navigation 124 included in the image collecting device 120.

Here, when it is determined that the movement of the surveillance region is detected through the image storage device 110, the image storage device 110 operates the camera unit 111 to capture and store an image of the surveillance region, and the image storage device. If it is determined through the 110 that the movement of the surveillance zone is not detected, the image storage device does not operate the camera unit 111.

Referring to Figure 7 will be described in more detail with respect to step S100.

Referring to FIG. 7, in the detecting of the movement of the surveillance region through the image storage device 110 (S100), first, the movement of the surveillance region is detected by the sensor unit 115 of the image storage device 110. Or detect the movement of the surveillance region through the change processing of the image acquired by the processor 114 (S101).

Thereafter, the processor 114 determines whether the surveillance region moves (S102). In the case where the sensor 115 is not present in the image storage device 110, the processor 114 determines whether the image is acquired by the processor 114. Change processing can be used to determine whether or not to move.

If it is determined by the processor 114 that the movement of the monitoring area is detected, the processor 114 transmits an operation signal to the camera unit 111 (S103).

On the other hand, if it is determined that the movement of the monitoring area is detected by the processor 114, the processor 114 continues from the sensor unit 115 without transmitting an operation signal to the camera unit 111. Only when it is determined that the movement of the surveillance region is detected while receiving the motion detection signal, the camera unit 111 transmits an operation signal so that the camera unit 111 can capture an image of the surveillance region.

As described above, in the video surveillance system and the video surveillance method using the same, the video storage device 110 and the video acquisition device 120 display an image of the surveillance region through the video storage device 110 without a real-time network connection. After capturing and storing the image, the image collecting device 120 collects the stored image from the image storage device 110 only when necessary and searches the stored image to monitor the surveillance area afterwards.

Therefore, no cable construction is required for network connection, and since the captured image is not transmitted in real time, communication cost can be greatly reduced, and the image storage device 110 for capturing and storing the image is different from the image collection apparatus 120. Can be installed separately and independently so installation is very easy and is not restricted by the installation site

On the other hand, since the image storage device 110 for capturing and storing the image of the surveillance area can be arranged independently without a network connection, the image storage device 110 is concentrated in the main surveillance area and then searched for after image. See more accurately and closely behind the major events

In addition, the image storage device 110 can shoot and store the image of the surveillance area independently to solve the image transmission distance problem, it is possible to obtain a high-quality image can significantly improve the video surveillance effect.

In addition, the storage capacity of the image storage device 110 may be reduced by capturing and storing an image of the surveillance area by the image storage device 110 only when motion is detected in the surveillance area.

Therefore, it can be easily installed in areas where power supply or cable construction is difficult, or in areas where camera installation is difficult, and can be conveniently used in areas requiring post-response, and concentrated in places like crime-prone areas where crime is likely to occur. Prevent blind spots from occurring
