1. A method comprising:
- recording and storing still images on an image server from a plurality of still cameras corresponding to respective coverage areas having predetermined locations, wherein the still cameras record the still images at periodic intervals, wherein recording and storing the still images is automatically initiated in response to a predetermined event such that no recording and storing of the still images occurs prior to the predetermined event;
determining, storing and timestamping location information associated with a wireless location device carried by an object, the location information corresponding to one or more of the coverage areas, wherein the location information is determined based at least upon a determined distance of the wireless location device from one or more base stations;
in response to a surveillance request comprising a surveillance time window associated with the object that includes a time period prior to a current time period, determining which timestamped location information associated with the wireless location device carried by the object is within the surveillance time window;
determining which of the still images stored on the image server correspond to the location information associated with the surveillance time window; and
retrieving still images from the image server that are associated with the surveillance time window and that depend upon the location information associated with the object in order to track the object.

15. A system comprising:
-
a plurality of still cameras arranged to record still images from respective coverage areas having predetermined locations, wherein the still cameras record the still images at periodic intervals; an image server coupled to the still cameras and arranged to store the still images recorded by the still cameras, wherein the image server is further arranged to automatically initiate recording of the still images in response to a predetermined event such that no recording of the still images occurs prior to the predetermined event; a plurality of wireless base stations having respective predetermined locations and operable to communicate wirelessly with a wireless location device carried by an object; a location server arranged to determine, store and timestamp location information associated with a wireless location device carried by the object, the location information corresponding to one or more of the coverage areas, wherein the location information is determined based at least upon a determined distance of the wireless location device from one or more base stations; and a tracking server arranged to receive a surveillance request comprising a surveillance time window associated with the object that includes a time period prior to a current time period, to determine which of the still images from the image server correspond to the location information based upon timestamps associated with the location information, and to retrieve the still images from the image server that are associated with the surveillance time window and depend upon the location information associated with the object and with timestamps within the surveillance window in order to track the object. - View Dependent Claims (16, 17, 18, 19, 20, 21)
