■ Audio detection
A preset threshold can be congured 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 dene the triggering condition either as an audio
input rises above or falls below the alarm level.
■ Camera tampering detection
This option allows the Network Camera to trigger when the camera detects that is is being tampered
with. To enable this function, you need to congure the Tampering Detection option rst. Please refer
to page 114 for detailed information.
■ Manual Trigger
This option allows users to enable event triggers manually by clicking the on/off button on the
homepage. Please congure 1 to 3 associated events before using this function.

VADP (VIVOTEK Application Development Platform)
The triggering conditions detected by 3rd-party software modules, such as motion detection or line-
crossing (tripwire), can also be used as event triggers.
■ Temperature detection
Whenever the detected temperature breaches the high (upper) or low (lower) threshold, the breach
can be used as a triggering condition. The camera comes with an onboard temperature sensor, and
the thresholds can be congured in Application > Temperature detection.
