â– 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.
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.
â– Camera tampering detection
This option allows the Network Camera to trigger when the camera detects that is is being tampered

to page 124 for detailed information.
â– Manual Trigger
This option allows users to enable event triggers manually by clicking the on/off button on the
homepage. Please congure 1 to 3 associated events before using this function.
