Camera -> Advance -> Audio Detection (only certain models):
The INTELLINET NETWORK SOLUTIONS H.264 Megapixel Network Camera has
an integrated microphone, and it also allows the connection of an external line-
in source. The camera can monitor the audio levels and trigger an alarm if the
noise level exceeds a specified threshold.
Audio detection 1: Activate this option to use this function. Once activated, a
screen element to adjust the audio level and threshold is
overlaid over the background image.
Threshold: This value defines the audio level that triggers an alarm.
The higher this value, the louder the noise has to be before
it is considered an alarm.
Sensitivity: The sensitivity parameter functions very much like the
input gain on a regular microphone. The higher the value,
the more sensitive the microphone becomes.
The green element (level meter) displays the audio level strength. The red
element indicates that the noise level has exceeded the threshold and an alarm
event has been created.
