■ Audio detection
A preset threshold can be congured with an external microphone as the trigger to system event.
The triggering condition can be an input exceeding or falling below a threshold. Audio detection
can take place as a complement to motion detection or as a method to detect activities not

audio input rises above or falls below the alarm level.
