Abstract: The present invention concerns a device and a method for monitoring a vehicle provided with an inner compartment at least partially delimited by a plurality of windows, particularly for the management of loss events, the monitoring device (10) comprising a central unit (11) connected to a plurality of sensors (12,13,14a,14b,15,16) adapted to detect at least one significant signal for identifying a loss event involving the vehicle, said plurality of sensors (12,13,14a,14b,15,16) comprising at least one inner video camera (14a, 14b) adapted to detect images inside and/or outside the inner compartment framed from the inside of the vehicle compartment and transmit them to the central unit (11), characterised in that the central unit (11) comprises means for processing the signals detected by the plurality of sensors (12,13,14a,14b,15,16) adapted to identify the occurrence of a loss event based on at least he signal detected by the at least one inner video camera (14a, 14b).
