The data receiving unit 212 transmits the data received from the additional apparatus 120 to the control center 150 via the network transmitting unit 218.

The traffic analysis unit 214 analyzes a network situation with the control center 150, for example, network traffic, and controls the data processing unit 216 based on the analyzed result. Specifically, the traffic analyzing unit 214 analyzes the network load state based on the network traffic, determines the resolution of the image when the analyzed network load state is equal to or greater than a predetermined threshold value (in case of overload) Lt; / RTI > For example, when the network load status is equal to or greater than a predetermined threshold (in case of an overload), the data processing unit 216 is controlled based on SD (Standard Definition) resolution. When the network load status is below a predetermined threshold value ), It controls the data processor 216 based on the HD (High Definition) resolution.

In addition, the traffic analysis unit 214 controls the transmission order of the image of the network transmission unit 218 when the network load condition is overloaded. The traffic analysis unit 214 may control the transmission order of the network transmission unit 218 to be a sequential transmission order when the network load state is overloaded, Respectively. Here, the important camera may be at least one of the multi-channel camera device 200 and the plurality of sub-cameras 100. [

For example, when the status checker 220 determines that a communication failure has occurred in one or more of the plurality of sub cameras 100 and the capacity of the data storage unit 224 exceeds a predetermined threshold capacity, for example, 50% It controls the data processing unit 216 to lower the resolution of the image received from the secondary camera 100, for example, from the HD level to the SD level. Accordingly, the data processing unit 216 converts the image of the secondary camera 100 received through the data receiving unit 212 into the SD level, and stores the SD level image in the data storage unit 224.

On the other hand, when the capacity of the data storage unit 224 exceeds the predefined capacity, for example, when the capacity of the data storage unit 224 exceeds 80%, the state control unit 220 determines And controls the data processing unit 216. Specifically, when the capacity of the data storage unit 224 exceeds 80%, the state control unit 220 determines that only the image of the specific sub camera 100 is stored in the data storage unit 224 And controls the processing unit 216. Accordingly, the data processing unit 216 converts only the image of the sub camera 100 corresponding to the selective storage setting and stores the converted image in the data storage unit 224. [

The state control unit 220 calculates and manages the total amount of electric power and the amount of power consumed through the interlocking with the power supply unit 226. The state control unit 220 further connects one or more sub cameras 100 or the additional devices 120 through the communication interface 210 The power supply unit 226 is controlled to supply power to the connected secondary camera 100 or the additional apparatus 120 based on the total power amount and the used power amount.

The state control unit 220 checks the operation state of the additional device 120 from the main control unit 222 to check whether there is an abnormality or not, and controls the state of the additional device 120 when an abnormality occurs. Here, the operating state means a communication, a data transmission state, and a power supply state, and a data transmission state means a transmission protocol, a transmission speed, and the like.

The state control unit 220 transmits the state check results of the multi-channel camera device 200, the plurality of sub cameras 100, and the additional device 120 to the control center 150.

The main control unit 222 determines the resolution of the image storage and transmission and controls the data processing unit 216 to control the operation state of the multi-channel camera device 200, the image transmission state of each of the plurality of sub cameras 100, The image setting state, the operation state of the additional apparatus 120, and supplies the collected information to the state control unit 220.

Thereafter, the multi-channel camera device 200 determines whether the network load state is overloaded through the traffic analysis unit 214 (S302).

As a result of the determination in step S302, in the overload state, the multi-channel camera device 200 controls the data processor 216 to change the resolution to a lower resolution in the image conversion (S304) And controls the network transmission unit 218 so that any one of the camera information is selected. Accordingly, the network transmission unit 218 determines which one of the sequential transmission order and the important camera information has been selected (S306).

As a result of the determination in step S306, when the sequential transmission order is selected, the network transmission unit 218 transmits the image photographed by the plurality of sub cameras 100 and the image photographed by the multi-channel camera apparatus 200 The images are successively transmitted to the control center 150 (S308). When the information of the important camera is selected, the images photographed by the plurality of sub cameras 100 and the image photographed by the multi-channel camera device 200 (S310) of the camera corresponding to the important camera information, converts the selected image to low resolution and transmits it to the control center 150 via the network transmission unit 218 (S312).

4 is a flowchart illustrating a process in which a multi-channel camera device 200 according to an exemplary embodiment of the present invention stores an image received from a plurality of sub-cameras 100. FIG.

Then, the multi-channel camera device 200 checks the storage capacity of the data storage unit 224 among the information collected through the main control unit 222 to determine whether the storage capacity exceeds a predetermined first threshold, for example, 50% (S402).

As a result of the determination in step S402, if the difference exceeds 50%, the multi-channel camera device 200 controls the data processor 216 to change the resolution from a high resolution to a low resolution (S404). Accordingly, the data processor 216 converts the image photographed by the plurality of sub cameras 100 and the image photographed by the multi-channel camera device 200 into low resolution and stores the low resolution image in the data storage unit 224 S406).

Then, the multi-channel camera device 200 checks the storage capacity of the data storage unit 224 among the information collected through the main control unit 222 to determine whether the storage capacity exceeds a predetermined second threshold, for example, 80% (S408).
