We use a simple coefficient to ensure overall accuracy. In order to apply the most accurate coefficient, we encourage clients to provide timestamped photographic or video ‘snapshots’ of the area around a sensor. A manual headcount is compared to the recorded data in Exposure Analytics, if we count 100 people and Exposure Analytics has detected 60 devices the coefficient is set at 60%. Another effective method is to compare the verified gate count to the raw data from a Smart EX sensor placed in the entry/exit area. Once we have a verified coefficient it is applied within the platform which shows the adjusted accurate data. With a 60% coefficient we display 100 visits for every 60 detected by our sensors.
