Lt; / RTI >

The communication unit 210 is a wired communication module for performing wired / wireless communication between the camera 100 and the event-

Or a wireless communication module. Thereby, the camera 100 and the digital image storage

The wireless communication device 200 may transmit and receive image data (image data) by various wired / wireless communication methods such as RS485, PSTN, TCP / IP, Zigbee, PLC,

And control signal data.

Here, the camera 100 may be a surveillance camera capable of PTZ (Pan, Tilt, Zoom).

The image storage unit 220 stores image data received from the camera 100 through the communication unit 210. That is,

An image received from the image processing apparatus 100 is digitized using an algorithm such as H.263, MPEG, MJPEG, etc. and compressed and stored in a hard disk (HDD).

The image analysis unit 230 analyzes the received image data from the camera 100 through the communication unit 210.

That is, the image analysis unit 230 determines whether the image data received from the camera 100 is a normal monitored object,

If it is judged to be a normal monitoring object, it is transmitted to the distance direction reading unit, and when it is judged as noise,

Perform the analysis process.
