Abstract: The present invention relates to a digital video recorder having an apparatus for receiving an automatic switched image by recognizing a source and a method thereof, which is capable of automatically determining whether an image channel is a SD signal channel or a HD-SDI signal channel and switching between these channels. The present invention has an advantage in that it provides a DVR having a source recognition automatic switched image receiving apparatus which is capable of automatically detecting whether an image signal is a SD signal or a HD-SDI signal in a channel and automatically switches between these signals, thereby allowing free channel change without requiring separate setting, which can result in higher flexibility of installation and channel setting and improved utilization of existing lines, and a method thereof.

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.
