Xovis is a Swiss company known for its 3D sensors. Its PC-series is used for door counting and people flow analytics, and its PF-series is designed for tracking across large areas. The sensors combine two optical image sensors into a stereo image and process it on the device, sending metadata such as counts and path coordinates. Xovis and its partners use the data for footfall, zone dwell time, occupancy, queues and conversion.
Shoppermotion uses a different method. Small Bluetooth tags on trolleys and baskets are located by ceiling antennas using Angle of Arrival positioning, with sub-metre precision, no cameras and no personal data. Each path is matched with its receipt, which makes metrics such as conversion per bay and verified in-store media exposure possible. See Perfect Store and offline attribution.
