Configuring Audio Detection Alarm
The camera can detect input audio signals for exceptions. When the rise or fall of volume exceeds the set
limit, or when the input volume reaches the threshold, the camera reports an alarm and triggers the set
actions. Make sure that an audio input device is correctly connected to the camera and audio input is turned
on in Error! Reference source not found..
