A motion detection method of a video camera includes calculating differences for a sum of accumulated differences (&#x394;SAD) for corresponding macro blocks in successive frames of video. The method may include identifying motion-generative macroblocks and regions of connected macroblocks. Candidate-motion regions may be defined in a frame and a bounding box may be formed around each of the candidate-motion regions. If corresponding bounding boxes in a plurality of successive frames have substantially the same location, size, and shape in the plurality of successive frames, and if the plurality of successive frames are in a temporal window of successive frames, then the corresponding bounding boxes may indicate motion.
