A roller shutter for securing a physical space within a vehicle, the roller shutter comprising: a protective barrier configured to be either in a rolled up, open, state, or in a rolled down, protective state; an electric motor configured to control transitions of the protective barrier between the rolled up and the rolled down states, or any state in between; a mesh of conductors being attached to the protective barrier; a processor ; and a memory storing instructions that, when executed by the processor, cause the roller shutter to: detect a physical break in the mesh of conductors by detecting a variation in impedance greater than a threshold variation when the impedance is measured between two opposite sides of the mesh ; when a break in the mesh of conductors is detected, signal that a break-in is detected; determine a valid open request based on a signal from an electronic lock that access is granted; open the protective barrier of the roller shutter by controlling the motor of the roller shutter to wind up the roller shutter when the valid open request is determined; determine when a user has exited the physical space within the vehicle based on a signal from an accelerometer attached to the vehicle or a signal from an accelerometer attached to the user; and close the protective barrier of the roller shutter by controlling the motor of the roller shutter to wind down the roller shutter when the user exit has been determined. a protective barrier configured to be either in a rolled up, open, state, or in a rolled down, protective state; an electric motor configured to control transitions of the protective barrier between the rolled up and the rolled down states, or any state in between; a mesh of conductors being attached to the protective barrier; a processor ; and a memory storing instructions that, when executed by the processor, cause the roller shutter to: detect a physical break in the mesh of conductors by detecting a variation in impedance greater than a threshold variation when the impedance is measured between two opposite sides of the mesh ; when a break in the mesh of conductors is detected, signal that a break-in is detected; determine a valid open request based on a signal from an electronic lock that access is granted; open the protective barrier of the roller shutter by controlling the motor of the roller shutter to wind up the roller shutter when the valid open request is determined; determine when a user has exited the physical space within the vehicle based on a signal from an accelerometer attached to the vehicle or a signal from an accelerometer attached to the user; and close the protective barrier of the roller shutter by controlling the motor of the roller shutter to wind down the roller shutter when the user exit has been determined. detect a physical break in the mesh of conductors by detecting a variation in impedance greater than a threshold variation when the impedance is measured between two opposite sides of the mesh ; when a break in the mesh of conductors is detected, signal that a break-in is detected; determine a valid open request based on a signal from an electronic lock that access is granted; open the protective barrier of the roller shutter by controlling the motor of the roller shutter to wind up the roller shutter when the valid open request is determined; determine when a user has exited the physical space within the vehicle based on a signal from an accelerometer attached to the vehicle or a signal from an accelerometer attached to the user; and close the protective barrier of the roller shutter by controlling the motor of the roller shutter to wind down the roller shutter when the user exit has been determined. <EOS>
