Most operators know their shrinkage rate as a single quarterly number. Overhead camera arrays let us break that number down into when, where, and most importantly, why.

Quantifying inventory shrinkage rates using overhead camera arrays.

Most operators know their shrinkage rate as a single quarterly number produced by a cycle count. Overhead camera arrays let us break that number down into when, where, and most importantly, why.

From a Single Number to a Timeline

A quarterly cycle count tells you that 2,400 units went missing sometime in the last 90 days. It cannot tell you whether that happened during a single bad shift or gradually across every aisle. Continuous overhead scanning replaces that single number with a timeline of exactly when each SKU count changed.

Attributing Loss to a Cause

By correlating shelf-occupancy drops against scan events, staffing schedules, and pallet movement logs, our models can separate shrinkage into three broad buckets: misplacement, damage, and unexplained loss.

In pilot facilities, misplacement alone accounted for a significant share of what had previously been recorded simply as shrinkage, meaning the inventory was never actually gone, just miscounted.

Once you can see where a discrepancy happened, most of what used to be called "shrinkage" turns out to be a location problem, not a loss problem.

That distinction changes how operators respond: a misplacement problem gets fixed with better slotting discipline, while a genuine loss problem gets escalated to security and process review.
