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.
