A graph displays audio when is detected. Audio that is below the Sound Intensity Threshold is displayed
in green. When audio exceeds the defined threshold, it creates an audio event and is displayed in red.
Figure 73: Sound Intensity Threshold
A number of actions can be taken, including:
Storing a snapshot of the audio event in the camera’s microSD card
Sending a snapshot of the audio event to an FTP server
Storing a recording of the audio event in the camera’s microSD card
Creating an OSD (On-Screen Display) overlay on the recording or snapshot
Sending an email notification of the audio event
Setting a low threshold (for example, 25) means that the camera is more sensitive to noise, which results
in more alerts (displayed in red). The setting depends on the situation and environment. If the scene is
located in a quiet place, it is possible to use lower threshold. A noisy location requires a higher threshold.
When selecting Record to Edge, the recording includes the audio track. OSD must be enabled on the
Events Source > Audio screen, as well as from the System > Basic Configuration > OSD screen, in
order to insert on-screen displays on clips and snapshots.

To set the audio level
