Abstract: A video collection system includes: a plurality of terminals; and a video collection server that requests at least one of the plurality of terminals to perform information provision. The video collection server includes a calculation part, a determination part, and a request part. The calculation part calculates, based on information acquired from a camera(s), a first area(s) imaged by the camera(s). The determination part determines a second area(s) as an information provision target(s) based on a location(s) of the first area(s). The request part selects, based on respective locations of the plurality of terminals and a location(s) of the second area(s), a terminal(s) to be requested to perform the information provision from the plurality of terminals and requests the selected terminal(s) to provide video data of the second area(s).
