1. A system for detecting a low shelf item supply at a retail facility, the system comprising:
a database storing data corresponding to a plurality of retail items disposed within the retail facility and an aisle location associated with some of the plurality of retail items;
a plurality of aisles within the retail facility and aisle markers disposed within at least several of the plurality of aisles;
a cart configured to received and transport items comprising the retail products;
an image capturing device configured for use with the cart and configured to:
record the aisle markers by which the cart travels during use to generate digital image data; and
generate electronic data representing one or more timestamps indicating when each of the aisle markers was recorded by the image capturing device;
a control circuit in communication with the image capture device and the database and configured to:
analyze the digital image data including the recorded aisle markers received from the image capturing device associated with the cart and process the digital image data to correlate a time lapse between the one or more timestamps in order to determine a path of movement of the cart through the retail facility;
analyze at least one image captured by the image capturing device associated with the cart and the path of movement of the cart through the retail facility to determine a list of items removed from at least one shelf at the retail facility;
identify, based on an overlap between the path of movement of the cart through the retail facility and the list of the items determined by the control circuit to have been removed from the at least one shelf at the retail facility, a particular aisle location at the retail facility where one of the items was removed from at least one shelf at the retail facility is found;
identify a low shelf item supply at the retail facility based upon an identification of the particular aisle location at the retail facility where the items were determined by the control circuit to have been removed from the at least one shelf; and
generate an electronic notification of the low shelf supply.
