Face Exposure: Check the checkbox to enable the face exposure. The device automatically adjusts
exposure level when human faces appear in the scene.
Reference Brightness: The reference brightness of a face in the face exposure mode. If a face
in the actual scene is brighter than the set reference brightness, the device lower the
exposure level. If a face in the actual scene is darker than the set reference, the device
increases the exposure level.
Minimum Duration: The extra time the device keeps the face exposure level after the face
disappears in the scene.
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.
Note: The face filtering time (longer than 0s) may increase the possibility of the actual
capture times less than the set value above.
