Abstract: Disclosed herein is a security-enhanced CCTV system. The security-enhanced Closed-Circuit Television (CCTV) system includes a plurality of CCTV cameras installed at locations desired to be captured. An image processing device is installed outside an Operations Room (OR) so as to control the CCTV cameras and to store and output captured images. A resource distributor is installed inside the operations room, with the resource distributor being connected to the image processing device in a wired or wireless manner, and is configured to receive stored images from the image processing device or mutually communicate control signals required to control the CCTV cameras with the image processing device. An input/output device outputs the control signals for the CCTV cameras or displays the captured images through the resource distributor.
