1. A security system for an area under surveillance comprising: a first memory including ontology data stored thereon, the ontology data defining interrelationships between a scanner associated with access to a room of an area under surveillance, a camera with a field of view at least partially overlapping a footprint of the room, an identifier configured to be scanned by the scanner and associated with a person, and a security policy including one or more predefined conditions, which when satisfied, indicate when a security threat exists, wherein the security policy includes a response an operator is to perform if the conditions are satisfied; a relational database including temporal data and spatial data stored thereon, the temporal data including time series entries corresponding to scan logs of the scanner including a scan read that indicates a time at which the identifier was scanned, the scanner that scanned the identifier, and whether the person was allowed or denied access based on the scan read, and the spatial data including a location of the camera, a coverage area of the camera, one or more locations of one or more doors to the room, a location of an asset in the room, and a location of the scanner; a query module, executable by a processor configured to receive a query and search the ontology data, the temporal data, and the spatial data in response to receiving the query, wherein the query module is configured to run periodic pre-programmed queries to the first memory and the relational database to determine if the security policy has been violated, and wherein the security policy includes an asset-missing security response configured to automatically send a series of queries to the query module, the series of queries configured to search the ontology data, the spatial data, and the temporal data to: determine, using the spatial data, the room where an asset that went missing is supposed to be; determine, using the spatial data, one or more scanners associated with the room; identify, using the temporal data, one or more identifiers in a list of identifiers that were scanned by the one or more scanners in a specified time window; identify, using the temporal data, one or more other scanners that have scanned the one or more identifiers in another list of identifiers in another specified time window: calculate the predicted future path of one or more persons associated with the one or more identifiers based on the identified one or more scanners and one or more other scanners; and identify one or more cameras with a field of view that intersects the predicted future path; and a display module configured to generate a display signal to show a floor plan of the area under surveillance, the floor plan including one or more icons overlaid thereon, the one or more icons indicating the location of the camera, the field of view of the camera, the location of the scanner, a location of the identifier, the one or more doors, a predicted future path of the person, a real-time image capture of the camera when a field of view of the camera intersects with the predicted future path of the person, and a historical path of the person, the display signal further shows security response steps in accordance with the security policy.
