button to refine your search.
You can search for the following events:
• General Motion. Detect all movements in the defined area.
• Foreign Object.
Trigger an alarm when an object appears in the defined area on the
screen.
• Missing Object.
An alarm is triggered when the selected object is removed from the
defined area on the screen.
• Focus Lost.
The system informs you when any camera loses its focus.
• Camera Occlusion.
An alarm is triggered when the camera is blocked.
 To use intelligent search:
1. Define the detection zone by dragging to draw a detection zone.
You can define more
than one zone by repeating this step.
2. (Optional)
To search for a missing object, define a detection object by dragging to draw a
detection zone.
3. Modify the sensitivity setting by changing the slider control.
Moving toward the right increases the sensitivity level. For general motion, a relatively
small movement triggers the alarm.
4. Set the interval.
Moving the slider toward the right increases the time interval so that the alarm is not
triggered unless the movement lasts longer
.
5. Select the Stop when found check box.
