A method for surveillance of a scene and alerting of activities of objects in the scene, including the procedures of acquiring a preliminary image of the scene, and marking and classifying at least one stationary object in the preliminary image, according to a predetermined classification, each of the classification types of the stationary objects having at least one visual behavioral characteristic. The method also includes acquiring a 2D image of the scene, and identifying objects in the 2D image with marked objects of the preliminary image. The method further includes determining if movement was detected in the image, and acquiring another image, if no movement detected. The method also includes determining if detected movement conforms to characteristics of classified stationary object associated with the movement, and acquiring another image, if the movement conforms to the characteristics of the stationary object. The method further includes alerting when the movement does not conform to the characteristics.
