Apparatus for secured video signal transmission for video surveillance system

摘要

Disclosed is a video security system and a method for operating the system. The video security system includes a video camera including circuits for use encrypting data or inserting a security signal, thereby generating a secured video signal for transmission. The system further includes a receiving unit, which is configured to receive the transmitted secured video signal. The receiving unit includes circuits to decrypt any encrypted signals and/or to manipulate security signal to confirm that there is no hacking or interception during the transmission. The method for operation of the security system includes providing a usable video signal and processing the usable video signal to provide a secured video signal. The usable video signal is a video image signal for use in a display with substantially little or no signal processing. The secured video signal includes at least one of an encrypted signal and a security signal. The method further includes processing secured video signal for displaying the video image conveyed in the secured video signal.
