The invention relates to an electrified net responsive to a forcing of the net itself. The net is manufactured by weaving a single wire capable of conducting electrical current. The wire comprises two ends at which an electrical voltage can be applied, and is woven so as to form a plurality of meshes which are nearly identical to one another. The wire includes a core made of a metal material or carbon fiber, wound by a sheath made of a material which is electrically insulating. By virtue of the presence of the sheath, no short-circuit can occur at the knots of the net where the two wire segments cross each other. The net comprises an electrical voltage generator and an electrical current detector connected to the conductor wire at said ends. The detector allows to detect possible interruptions of the circulation of electrical current in the conductor wire caused, for example, by forcing the net. The detector is connected to a device capable of controlling the emission of an alarm signal when said interruption is detected. The net further comprises a geolocator for determining the geographic position thereof, and a hygrometer, a thermometer and a light meter for measuring the air humidity rate, the temperature and the luminosity in the environment surrounding the net, respectively. These measurements are transmitted, together with the alarm signal, to the subject in charge of receiving said signal when the detector detects an interruption of the circulation of electrical current.
