• The sound detection feature cannot detect sound when the [Input] setting is set to [Disable] on the
[Audio] page (see Page 144).
• The [Camera Microphone Sensitivity] setting on the [Audio] page affects sound detection (see
Page 144).
• If there are many false detections, lower the sensitivity of the [Camera Microphone Sensitivity] on the
[Audio] page. If no detections are made, increase the sensitivity of the [Camera Microphone
Sensitivity] (see Page 144).
• The sound detection feature is triggered when a higher volume sound than the ambient noise is
detected. We recommend setting the [Camera Microphone Sensitivity] on the [Audio] page to [High]
for quiet places such as library, [Low] for noisy places, and [Very Low] for continuously noisy places
such as factories (see Page 144).
• While the sound detection feature can be used to trigger image buffering, images buffered to the internal
memory do not contain audio.
• The sound detection feature cannot detect sound while using the pan, tilt, or click to center features or
while the built-in alarm is sounding.
• Ambient noise may cause false detections.
• The sound detection feature is triggered by sound volume only, not by the characteristics of the sound.
