Abstract: Methods, systems, devices and computer readable media for identifying a video camera of a video surveillance system are provided. A plurality of video streams of a plurality of video cameras are obtained. At least one video camera of the plurality of video cameras captures a visual identifier outputted by a mobile device. The visual identifier is detected in at least one video stream of the plurality of video streams based on searching for the visual identifier in the plurality of video streams. The at least one video camera capturing the visual identifier is identified from the at least one video stream having the visual identifier detected therein. Identification information of the at least one video camera capturing the visual identifier is transmitted to the mobile device.

Abstract: A method of controlling cameras from a set of cameras in a geographical region to obtain image streams capturing a topographical area of interest. It includes receiving an area data object defining the topographical area of interest; deriving a centroid of the topographical area of interest from the area data object; determining a subset of target cameras from the set of cameras having a zone of potential coverage comprising the topographical area of interest; computing pan and tilt angles for one or more target cameras of the subset of target cameras; computing for one or more target cameras of the subset of target cameras a zoom factor, the zoom factor calculated by determining a narrowest field of view angle of the target camera that encompasses the entire topographical area of interest; and generating transmission commands for the subset of target cameras.
