Traditional videosurveillance devices usually shoot images of a place, giving to the users long registrations very difficult to be consulted. With N.A.A.W. based products, equipped with videocameras, it is possible to create videosurveillance systems which are connected to each other. Whenever they notice a movement or a change of the filmed scene, they start working and immediately inform the same users or the police, signalling the intrusion.
