The smoke detecting method and system capture a plurality of images; determine whether a moving object exists in the plurality of images; select the images having the moving object to be analyzed; analyze whether the moving object is moving toward a specific direction and a displacement of a base point of the moving object; and determine the moving object as a smoke when the moving object is moving toward the specific direction and the displacement is less than a threshold value.
