Understanding [Threshold]
Sound detection threshold can be adjusted. Understanding how threshold will help you adjust the sound
detection feature to suit your needs.
[Threshold]: Determines at what point the sound detection feature is triggered. A lower threshold means less
sound is needed to trigger the sound detection feature, i.e., sound detection is triggered at lower volumes. A
higher threshold means more sound is needed to trigger the sound detection feature, i.e., sound detection is
only triggered at higher volumes. Note that the [Camera Microphone Sensitivity] setting on the [Audio] page
controls microphone sensitivity (Page 144); if the microphone sensitivity is adjusted, the [Threshold] setting
for the sound detection feature may also need to be adjusted to achieve the desired results.
[Preview]: Refer to this area to see how the current settings (effective after clicking [Save]) detect sound.

Parameter Display Meaning
[Threshold]
Low threshold (A)
[Preview]
Low threshold (A), no
sound is detected
[Preview]
Low threshold (A), low
volume (B), sound
detection is not
triggered

[Threshold]
High threshold (A)
[Preview]
High threshold (A), no
sound is detected
[Preview]
High threshold (A),

sound detection is not
triggered
[Preview]
High threshold (A), high
volume (C), sound
detection is triggered
