A tracking system includes an image capture device, a memory and a processor. The image capture device is used to capture a video stream in a target area. The memory stores face information. The processor reads the face information from the memory and reads the video stream from the image capture device. The processor is used to identify a face matching the face information in the video stream to track the movement of the face in the target area. The processor is used to determine whether a distance between the face and the image capture device is greater than a predetermined distance. The processor is used to track the movement of a human figure corresponding to the face in the target area when the processor determines that the distance is greater than the predetermined distance.
