Audio detection tab — Set the
audio detection
Audio detection detects sound picked up by a
microphone, and outputs an alarm beyond a certain
threshold.
Audio detection
Select On to activate the function and set the sensitivity.
Sensitivity
Set the Sensitivity to Low, High or Manual. If Manual
is selected, you may set the sensitivity manually.
Manual sensitivity
Set the Manual sensitivity from 1 to 100, the larger the
number, the greater the sensitivity.
Detection status: When Audio detection is set to On in
the Audio detection tab, the detection status is
displayed.
If excessive sound is picked up by the microphone,
“Detected” appears; otherwise “Non-detected” is
displayed. The input volume is indicated in a bar that
helps you to calibrate detection levels.
Notes
• Test audio detection to confirm that it is functioning as
desired.
• The audio detection function sets the detection level
automatically according to the statistical samples of
input volume and the sensitivity. Thus, the detection
level may differ even with the same sensitivity.
• The detection of input volume cannot be updated
when the Audio detection tab is open. This means at
this time the detection level is not adjusted
automatically according to the input sound. According
to the characteristics, test audio detection when the
Audio detection tab is open.
• Before setting sensitivity, in order to optimize
detection, place the microphone in an ordinary
location and sound environment for about
3 minutes before opening the Audio detection tab.
• The Audio detection alarm is off during playback of
audio files.
• The Audio detection alarm is off while uploading
audio (from a computer).
