1. Create a Metrics Campaign and assign it to the devices being tested.
2. Stand in front of the camera, and check for visitor metrics on screen.
   
3. Act like your visitor would! Walk around, make turns, stay at the distance thay would be, check if the lighting is enough. Your face should be detected at up to 4 meters. Your body should be detected at up to 8 meters (in case you are using People Counting)
