# setConfidenceThreshold method

void setConfidenceThreshold(

1. int confidenceThreshold

)

Sets the confidence threshold, in the range (0;100). Hint: Default value is 50. Note: Setting a high threshold reduces false detection but can increase the number of undetected faces.

param confidenceThreshold Confidence threshold, in the range (0;100). throws FaceException An error has occurred during Face Library execution.

## Implementation

    void setConfidenceThreshold(int confidenceThreshold) {
      var err = faceSDK.id3FaceTracker_SetConfidenceThreshold(_pHandle.value, confidenceThreshold);
      if (err != FaceError.success.value) {
        throw FaceException(err);
      }
    }
