In preparation for this, a section of interest is created within the frame after the trailing frame by estimating the coordinate value of an object to be identified in the frame after the trailing frame, and the created section of interest is compared with the object detected in the frame after the trailing frame. Accordingly, an identical object determination module that determines whether the object detected in the subsequent frame and the object detected in the subsequent frame are identical is disclosed.

In addition, Republic of Korea Patent Publication No. 10-1698063 provides CCTV camera remote monitoring that monitors the normal operation of CCTV cameras connected to the network through a PoE (power over ethernet) hub and restores them to normal when an error occurs. A method and system are disclosed.
