■ 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.

■ 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 congure 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 congure 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 congured in Application > Temperature detection.
