4.
The following options are available to further reduce false alarm:
 Noise Tolerance: Enable to ignore video noise and move the slider to adjust the level. The
higher the level, the more tolerant the system is to video noise. If the surveillance area is prone
to produce high noise possibly due to weather or light changes, set the level to High.
 Ignore environmental changes: Ignores environmental changes such as rain or snow. When
selected, objects moving steadily and repeatedly in the same direction for over 1.5 seconds
will be filtered out and ignored.
 Minimum Duration: Sets the minimum duration for which motions must persist for the system
to issue a motion alarm. Specify the minimum duration in seconds (Max. 60 seconds).
5. You can reduce CPU loading by selecting Process Video in Lower Resolution. When enabled,
GV-VMS compresses live view into a lower resolution before GV-VMS detects if there is motion,
which reduces CPU loading, but may affect the accuracy.
6. To set the frame rate setting for motion events, click Video record frame rate and select Urgent
Event or General Event. Normally, you would set a higher frame rate for Urgent Events (Ex: full
frame) and select Urgent Event here for motion events. The frame rate for General Event and
Urgent Event can be defined in the camera’s General Setting page. See Configuring General
Setting in Chapter 2 for details.
7. Under Event Trigger, select the actions to take when motion is detected.
 E-mail: Sends e-mail notification. To see how to set up the e-mail server, refer to Setting Up
Email Notification later in this chapter.
 Output Module: Triggers the selected output device. To see how to set up I/O devices, refer
to Chapter 6 I/O Applications.
 Register Motion Event: Registers motion events to System Log.
 Invoke Alarm: Activates computer alarm by playing the selected sound file.
8. Click OK to save your settings.
