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 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: The present invention provides flexible implementation of business logic in a business application. General and reusable business logic is implemented such that customized solutions for business applications are easier to develop. Binding properties in business entities to various logic implementations is utilized to reuse the business logic. Parameters can be set up in metadata that control the behavior of the business logic implementations.
