1. A method for performing a system analysis of a surveillance system including a plurality of components, said method comprising the steps of: representing selected ones of the plurality of components and associated relations among the representations of the selected components wherein the plurality of components comprises a plurality of audio and/or video components, with each of a plurality of domains, wherein at least one of the plurality of components is associated with at least two of the domains; providing a mapping between a plurality of observable events and a plurality of causing events occurring in the selected components in each of the domains, wherein selected ones of the observable events and causing events are associated with each of the at least one component associated with at least two of the domains; determining at least one likely causing event based on at least one of the plurality of observable events by determining a relationship between each of a plurality of first values and a plurality of second values; wherein the first plurality of values are associated with the plurality of observable events; and wherein the second plurality of values are the plurality of causing events; and determining a likely causing event by correlating the causing events associated with each of the domains.
