The conversion rate is the percentage of total visits that are detected within the detection zone (inside visits) as setup in the sensor configuration.

If you set the detection zone to 120 (the max), then the conversion rate will be 100%. If you set it to a very small number - representing a very tight radius, then the conversion rate (and inside visits) will approach zero.
The idea is to set the detection zone to capture the "inside" visits that represent the physical boundaries of a location such as a store.
