Embodiments described herein facilitate receipt of image data, by providing apparatus and methods for constructing and/or utilizing a database of networked imaging devices. Communication transmitted over a network is identified as being from an imaging device. One or more identifiers, under which the communication is transmitted, are then extracted from the communication. For example, one or more Internet Protocol (IP) addresses may be extracted. The identifiers are associated in a database with respective physical locations. When a particular area is defined as an area of interest, at least one of the identifiers is selected from the database, the selected identifier being associated with a physical location that is within, or near, the area of interest. Image data transmitted under the selected identifier is then received by the interested parties.
