been removed from the area for longer. Move to the left to reduce the
time interval.
Set up an appropriate Interval value will reduce the chance of false alarm.
For example, you can lower the Interval to avoid the alarm being
triggered by an object in view for a short time.
2.6.3 Missing Object
Missing Object: Alarm is set off when the selected
object is removed from the defined area on the
screen.
Define detection zone: Before detecting missing object,
it is required to define a detection zone. Left click and
drag to draw a detection zone. Alarm will be triggered
when the defined object is removed from the
detection zone.
(Ex: In an art gallery if a painting is removed an alarm
will trigger general motion in the area by public will be
ignored)
Define object size: This tells the System how big the defined object is.
Drag and draw a square that is about the same size as the object that
you want to protect on the screen.
Sensitivity: Modify the sensitivity setting by changing the slider control.
Move toward right will increase the sensitivity level and a relatively small
movement will trigger the alarm; in contrast, move the slider control
toward left will reduce the sensitivity for movement detection.
Time Interval: Click and move the slider control to the right to increase
time interval so that the alarm will only be triggered when the movement
lasts longer. Move to the left to reduce the time interval.
2.6.4 Lose Focus/ Camera Masking
Lose Focus: System will inform you when the camera(s) lose its focus.
Camera Masking: Alarms when any of the cameras is blocked.
