Ground truth collectors get passwordless access to the BlueZoo ground truth app, which allows them to collect the ground truth data for all or specific sensors in the account, as specified by the admin.
To add a new collector for all sensors in the account, the admin is required to be logged into the BlueZoo Foot Traffic app. Then click on the hamburger menu in the bottom left corner> Users> (+) to add and invite a new collector. Using the email address added, the collector will then be able to login into the app and collect ground truth data for all existing thresholds.
Or, to let a collector collect data only for specific locations, go to Sensor locations > Select a location > Collectors > (+) to add a collector's email address.
