■ 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 covered by the
camera's view. Please refer to page 129 Applications > Audio detection for more details.
Once you have a preset audio alarm level, you can dene the triggering condition either as an audio
input rises above or falls below the alarm level.
■ Manual triggers
An event can be manually triggered by the manual trigger buttons on the main page.
■ VADP
It is presumed that you already uploaded and enabled the VADP modules before you can associatee
VADP triggers with an Event setting.
Click on the Set VADP Trigger button to open the VADP setup menu. The triggering conditions
available with 3rd-party software modules known as VADP will be listed. Use the arrow buttons to
select these triggers. Users may implant these modules for different purposes such as triggering
motion detection, or applications related to video analysis, etc. Please refer to page 132 for the
conguration options with VADP modules.
