How to Configure a VMD alarm
Step 1:
Check the Enable VMD alarm box. If the Administrator wants to show the red frame alert on the image on the
VPort 26’s web homepage, check the Show alert on the image when VMD is triggered box. Click on the
Save button to save these two configurations.
Step 2:
Select Stream 1 or Stream 2 for video motion detection. Check VMD1 through 3 to enable the respective VMD
windows. Left click the title bar of this window to move the location of the VMD window, or drag the border to
change the window size so that it fits the desired VMD area.
Step 3:
Assign a name to the VMD window in the Window Name column.
Step 4:
Set up the Percent% parameters for individual VMD windows and the Sensitivity for all VMD windows.
Step 5:
Click on the Save button to save the settings.
Step 6:
To test the VMD condition, check the action of the graphics bar on the left side of the save button. Wave your
hand in front of the camera, in the VMD area, and then note which color shows up in the graphics bar. Green
means VMD is not triggered. Red means VMD is triggered.
Step 7:
Set up the Trigger Conditions and Actions of each VMD, and then click on the Save button to save these
configurations.
NOTE
Video Motion Detection is provided as a reference because it is environment
-
dependent. When the settings are
configured to be very
sensitive to motion, some triggered events might actually be false alarms that were
triggered by only a small difference between sequential images. These false alarms might be triggered by the
flicker of fluorescent lights, the movement of shadows, or simi
lar everyday events.
