An automated surveillance system is disclosed in this specification. The system comprises a computing system arranged to receive a plurality of surveillance feeds from a surveillance network and detect characteristics of the surveillance feeds that are indicative of categorized events. Each of the surveillance feeds has a geospatial reference tag that identifies the origin of content contained within the feed. The surveillance system determines a response reaction to detected events and identifies potential response units in the vicinity of the surveillance location using the geospatial reference tag.
