7.10 Audio Detection
The audio detection module analyzes and responds to changes in noise level in the place
where the camera is installed. This menu provides options for adjusting the audio detection
threshold and sensitivity. This saves recording space by triggering an alarm recording only when
audio is detected. When the audio detection triggers, the camera creates an alert message or a
video file and sends it to e-mail, FTP server, network storage, or over HTTP (Pic. 7.23).
Threshold: specify the threshold at which audio detection is triggered.
Sensitivity: adjust the audio detection sensitivity. The closer the slider to the right position,
the more the sensor is sensitive.
You can see the sound indicator in the live view window. The green frame indicates that the
camera detects noise; the red frame indicates that the threshold is exceeded and the audio
detection is triggered.
IMPORTANT!
To use the audio detection as an event trigger, connect an external microphone to the camera and enable
the audio codec at SETTING – Basic – Camera – General.
