The disclosure provides abnormal behavior detecting apparatus and method. The apparatus may include: an extracting device configured to extract, from a video segment to be detected, an image block sequence containing a plurality of image blocks corresponding to a moving range of an object in each image frame in the video segment; a feature calculating device configured to calculate motion vector features of the image block sequence; and an abnormal behavior detecting device comprising two or more stages of classifiers that are connected in series. The classifiers are configured to receive the image block sequence and the motion vector features stage by stage and detect the abnormal behavior of the object. If a previous stage of classifier determines that the to image block sequence contains an abnormal behavior, a next stage of classifier further receives and detects the image block sequence, until last stage of classifier.
