Display case door with interior facing camera

A display case door system comprising:

• a display case door comprising:
• a transparent panel assembly;
• and
• hinges coupled at a first peripheral edge of the transparent panel assembly;
• a camera coupled proximate to a second peripheral edge of the transparent panel assembly, the second peripheral edge being opposite the first peripheral edge, wherein the camera is coupled to the display case door at an angle relative to the second peripheral edge such that at least a majority of shelves contained within an interior of a display case are within a field of view of the camera when the display case door is opened angularly along the hinges by a threshold amount to capture images of the interior of the display case with the display case door mounted to the display case;
• a sensor coupled to the transparent panel assembly;
• at least one processor in electronic communication with the sensor and the camera;
• and
• a data store coupled to the at least one processor having instructions stored thereon which, when executed by the at least one processor, causes the at least one processor to perform operations comprising:
• obtaining, from the sensor, a signal indicating that the display case door is open by the threshold amount;
• and
• in response to receiving the signal indicating that the display case door is open by the threshold amount, initiating the camera and triggering the camera to capture an image of the interior of a display case.
