A retail unit comprising: a display module capable of accommodating one or more retail items ; a housing structure for housing the display module , the housing structure defining an access opening configured to enable insertion and removal of the one or more retail items in the display module ; a door module comprising a hinge mechanism positioned on a peripheral portion of the access opening so as to define a pivot axis on a door panel configured to pivot about the pivot axis of the door panel , away from the access opening of the display module ; an imaging module coupled to the door module , the imaging module comprising a first and a second imaging sensor configured to acquire images of access opening of the display module; wherein the first and the second imaging sensors are positioned in a peripheral portion on the side of the door panel , opposite the pivot axis, and wherein the retail unit further comprises a processor module connected to the imaging sensors , the processor module being configured to: - receive the images acquired by the imaging sensors - perform image processing to detect a change between two successive images received from a same imaging sensor of the first and second imaging sensor to detect opening and closing of the door module panel , characterized in that the processor module is further configured to: - stitch images received by different imaging sensors at the same instant to increase the field of view and allow reconstructing complete images of the access opening; and - communicate data associated with the processed images to a remote control center. a display module capable of accommodating one or more retail items ; a housing structure for housing the display module , the housing structure defining an access opening configured to enable insertion and removal of the one or more retail items in the display module ; a door module comprising a hinge mechanism positioned on a peripheral portion of the access opening so as to define a pivot axis on a door panel configured to pivot about the pivot axis of the door panel , away from the access opening of the display module ; an imaging module coupled to the door module , the imaging module comprising a first and a second imaging sensor configured to acquire images of access opening of the display module; wherein the first and the second imaging sensors are positioned in a peripheral portion on the side of the door panel , opposite the pivot axis, and wherein the retail unit further comprises a processor module connected to the imaging sensors , the processor module being configured to: - receive the images acquired by the imaging sensors - perform image processing to detect a change between two successive images received from a same imaging sensor of the first and second imaging sensor to detect opening and closing of the door module panel , characterized in that the processor module is further configured to: - stitch images received by different imaging sensors at the same instant to increase the field of view and allow reconstructing complete images of the access opening; and - communicate data associated with the processed images to a remote control center. - receive the images acquired by the imaging sensors - perform image processing to detect a change between two successive images received from a same imaging sensor of the first and second imaging sensor to detect opening and closing of the door module panel , characterized in that the processor module is further configured to: - stitch images received by different imaging sensors at the same instant to increase the field of view and allow reconstructing complete images of the access opening; and - communicate data associated with the processed images to a remote control center. <EOS>
