In selected embodiments video footage is automatically analyzed to determine whether product stock levels at particular product locations are low. Video analytics may be employed to track product removal from shelves and determine approximate quantities of product remaining on each shelf based on product size and dedicated shelf area. In selected implementations an alarm notification is generated to alert store personnel that restocking is appropriate. Such an alarm notification optionally includes a still image of the area corresponding to the alarm together with data related to the product and projected quantities needed to restock the shelf. In some embodiments the system automatically identifies the store personnel who are currently located in areas near where the alarm event occurred and the notification is wirelessly distributed to their mobile devices.
