Abstract
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.

53. A method of operating a video surveillance system, the method comprising:
-
receiving a video signal transmitted from a source;
identifying one or more irregularities in the transmission of the received signal, wherein the one or more irregularities are selected from the group consisting of interception, alteration, hacking, duplication and replacement of at least part of the secured video signal; and
processing the received video signal to produce a usable video signal, which is ready for use in a digital display with substantially little or no data processing. - View Dependent Claims (54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70)
