No, footfalls aren’t unique. If a same user visits a location two times a day, our pixel will fire twice. However, we track anomalies that we find in our database. Example 1: Lifesight invalidates users whose dwell time is less in the attributed locations. Example 2: Lifesight doesn't count employees in a shop or a restaurant as footfalls. How we do this is we track unique users everyday and if we see the same user at the same location at the same time almost every day, then we nullify them.
