Visitors, Visits, and Unique Visitors data can be accessed from the BlueZoo dashboard or directly through the data warehouse API. Visitors and Visits do not require any pre-configuration, whereas, Unique Visitors are required to be configured prior to a campaign start date.
Visitors- Also known as "occupancy count" are measured as a snapshot at a moment in time of the number of people within the sensor detection range. Visitors are stored at a quarter-hour granularity in the data warehouse. BlueZoo dashboard provides access to this data over quarterly, hourly, daily, and weekly time grain.

Visits- Are aggregated visitors over a period of time, also known as impressions. A new person entering a sensor's detection zone generates a visit as soon as seen by the BlueZoo sensor. If the sensor does not see a phone for 10 minutes or more, then it's established that the phone has left the detection zone, and the particular visit can be closed.

Unique Visitors- This is a measure of unique people and their recurrence over the defined campaign duration period, which can be a day, week, month, quarter, or a custom date range. The finest granularity for this metric, available in the data warehouse and the BlueZoo dashboard visualization, is daily.

The following diagram further demonstrates the difference between these analytics:
In the example above, Visits over this time period measure 7. Visits over the first half of this time period measure 4, and visits over the second half measure 3.
Visitors at the 1st, 2nd and 3rd time slots are 1, 3 and 4, respectively.
Unique visitors (indicated by color) measure 5 over the given time period. Visitor, indicated by red color visits in the first half of the day, leaves and then returns back in the later half, still accounting for 1 unique visitor with 2 recurrences in the given time period.
Of course, one visitor may account for multiple visits.
