Abstract
A dynamic object monitoring method including, setting types of monitored zones of a monitored region in a video frame captured by a network camera and setting device parameters and sensitivity values corresponding to each of the monitored zones. Analyzing the predicted macro blocks of a current shooting frame retrieved by the network camera according to the prediction mode of the MPEG-4 encoding algorithm. Counting a number of the predicted macro blocks of each of the monitored zones. Determining whether a number of predicted macro blocks of a monitored zone is equal to or greater than a corresponding preset value. A monitored zone is determined where a dynamic object is located. The device parameters of the network camera as device parameters of the monitored zone are adjusted where the dynamic object is located for recording.
