What is people counting in retail stores?

People counting in retail stores refers to the process of detecting and measuring the number of people entering or exiting a physical store using sensors or AI systems. These systems can be based on infrared sensors, video analytics, or AI-powered cameras. However, raw people counting does not distinguish between customers, staff, or delivery personnel. This is why many retailers are now shifting toward a more refined metric called Valid Footfall, which focuses only on unique customer visits after filtering non-customer traffic.
