Face Filtering
Face Filtering Time
It means the time interval between the camera detecting a face and taking a capture action. If
the detected face stays in the scene for less than the set filtering time, capture will not be
triggered. For example, if the face filtering time is set as 5 seconds, the camera will capture the
detected face when the face keeps staying in the scene for 5 seconds.
