10.1.3 Face Capture Algorithms Parameters
Set and optimize the parameters of the algorithm library for face capture. Go to
Configuration
→
Face
Capture → Advanced Configuration → Parameters .
• Face Capture Version : It lists the version of the algorithms library.
• Detection Parameters
­ Generation Speed : The speed to identify a target. The higher the value, the faster the target will be
recognized. Setting the value quite low, and if there was a face in the configured area from the
start, this face will not be captured. It can reduce the misinformation of the faces in the wall
painting or posters. The default value of 3 is recommended.
­ Sensitivity
: The sensitivity to identify a target. The higher the value, the easier a face will be
recognized, and the higher possibility of misinformation. The default value of 3 is recommended.
• Capture Parameters
­ Best Shot : The best shot after target leave the detection area.
­ Capture Times
: Number of times a face will be captured during its stay in the configured area. The
default value is 1.
­ Capture Interval
: The frame interval to capture a picture. If you set the value as 1, which is the
default value, the camera captures the face in every frame.
­
Capture Threshold : The quality of the face to trigger capture and alarm. A higher value means better
quality must be met to trigger capture and alarm.
­ Quick Shot : Defines quick shot threshold and maximum capture interval.
­ Quick Shot Threshold
: The quality of face to trigger quick shot.
­ Face Exposure : Check the checkbox to enable the face exposure.
­ Reference Brightness
: The reference brightness of a face in the face exposure mode. If a face is
detected, the camera adjusts the face brightness according to the value set. The higher the value,
the brighter the face.
­ Minimum Duration : The minimum duration of the camera exposures of the face. The default value is 1
minute.
NOTE:
If face exposure is enabled, make sure the WDR function is disabled, and manual iris
is selected.
­ Face Filtering Time
: 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
