 Check the human face image quality. If the quality is low, or the human face image is
vague, dark, or in the backlight, adjust the image quality.
 Check if the whole face can be seen from the video. If not, adjust the camera position.
 If false alarms still exist, adjust the abnormal human face detection sensitivity value to 1
to 2.
 Increase the time threshold (Index Value) of enhanced mode. Enhanced mode is enabled
