wherein a degree of non-secure status (Ens 1 to Ens 10 ) is selected to define a security situation of the enclosure ( 2 , 3 , 4 ), the visualization device ( 2 T) changed to an active alert configuration ( 67 ) in which modulation actions are proposed on the locking/unlocking device, alarms (Al), and modulated action (Am) being automatically triggered according to the degree of non-secure status (Ens 1 to Ens 10 ), based on an image and/or audio processing, and transmitted to the crew members depending on a phase of transportation;

wherein the securing of the interior of the vehicle enclosure is established by:

a consistency correlation between the images of the video cameras ( 21 a to 23 a , 21 b to 23 b , 24 to 28 ) in order to ensure an integrity of an auxiliary situational data (Tx, Hx, Px, Sx, Dx) and optionally, a selected degree of secure status (Es 1 to Es 10 ) or the degree of nonsecure status (Ens 1 to Ens 10 );

encryption of images transmission device, of setting signals transmission for a field of view and of wireless connections to the locking/unlocking device ( 6 V);

a biometrics recognition device for each authorized crew member to use the mobile visualization device ( 2 T) with predefined configurations ( 61 to 67 ) for a specific crew member.

2. The system of optimized securing and monitoring as claimed in claim 1 , wherein the video cameras ( 21 a to 23 a , 21 b to 23 b , 24 to 26 ) are associated with a microphone ( 20 M) connected to a card for processing the audio into a transmission signal of an audio processing card ( 20 c ), as well as temperature ( 55 ) and pressure ( 56 ) probes.
