Abstract: A method of controlling panning of a surveillance camera configured to perform panning over a set angle during a preset mode includes: obtaining an edge value with respect to each pixel of an object captured image of a panning-completed time, the edge value being a difference between brightness of a left adjacent pixel thereof and brightness of a right adjacent pixel thereof; obtaining an object vertical-line number among vertical pixel lines of the object captured image, the object vertical-line number being a number of a vertical pixel line in which a sum of the edge values is largest; and correcting the panning such that the object vertical-line number coincides with a reference vertical-line number corresponding to the panning over the set angle.

Abstract: Disclosed herein is a video search device comprising: at least one processor configured to implement an updating unit generating event object information based on feature information on an object detected in a video; and a storage configured to store comparison object information containing feature information on a reference object, wherein the processor is further configured to implement: an object information generating/deleting unit configured to create information on an object having a predetermined degree of similarity between the event object information and the comparison object information as final object information, and storing the final object information in the storage; and a data searching unit searching the final object information for data that satisfies a search criterion entered by a user.
