at least one laser sensor (1a; 1b) structured for detecting a movement in the vehicle (100) by emission of a laser beam and measurement of a respective time of flight;
at least one camera sensor (2a; 2b) structured for detecting a movement in the vehicle (100);
a command-and-control unit (3) operatively connected to the at least one laser sensor (1a; 1b) for receiving a first detection signal representative of the movement detected by the at least one laser sensor (1a; 1b) and to the at least one camera sensor (2a; 2b) for receiving a second detection signal representative of the movement detected by the at least one camera sensor (2a; 2b), the command-and-control unit (3) being configured and programmed for:

processing the first and second detection signal for verifying an achievement of a respective alarm condition;
provided the achievement of the respective alarm condition for both the first and second detection signal, sending a respective command signal to at least one between an alarm system (8; 9; 10; 11; 13) and an emergency system (15; 16; 17) mounted on the vehicle (100).
