Abstract: A computer implemented method of operating a video management system, the method comprising inputting, into the video management system, a plurality of virtual video streams generated by virtual video cameras within a dynamic 3D virtual environment; receiving, in the computer, at least one command from a user indicative of an instruction to alter a functioning of the dynamic 3D virtual environment and/or a functioning of the video management system; and displaying on a display, from the video management system, at least one virtual video stream and/or at least one alert, alarm and/or message implementing at least one alteration caused by the received command.

Abstract: A video surveillance system comprising a video management system, one or more computer-implemented digital devices and a plurality of application programs, the system being configured to run the programs on one of or across several of the said one or more computer-implemented digital devices, and configured to perform parallel processing of one or more groups of pictures from one or more video streams with the plurality of application programs in one or across several of the said one or more computer-implemented digital devices.

Abstract: A computer implemented method of training an operator of a video management system, the method comprising inputting, into the video management system, a plurality of virtual video streams generated by virtual video cameras within a dynamic 3D virtual environment; displaying on a display, from the virtual management system, at least some of the said virtual video streams, wherein at least one output video stream shows an event of interest; receiving, in the computer, at least one command from the operator indicative of a detection of the event of interest in the dynamic 3D virtual environment by the operator.

Abstract: A video surveillance system comprising a video management system and one or more digital devices, each of the one or more digital devices being configured to emulate at least one physical video camera, and to send video streams and/or video metadata via a computer network to a video-receiving system, wherein the video management system comprises: an input interface for receiving one or more video streams from one or more video cameras and/or other video sources, a processing unit configured to receive one or more input video streams from the input interface, each input video stream corresponding to one of the received video streams, and to store the input video streams in a video repository, and an output interface configured to send, via a computer network, one or more of the input video streams and/or one or more of the stored video streams to one or more of the digital devices.
