4.1.7 Camera Event - Missing Object

Alarm triggers when an object disappears in the defined area on the screen.













Alarm Event Option:

Sensitivity:

Click and move the slider control to the right to increase sensitivity so that minimal movement

will trigger the alarm. Move the bar to the left to reduce the sensitivity of movement. Setting up the
appropriate sensitivity value will reduce the chance of false alarms. For example, you can lower the
sensitivity to avoid the alarm being triggered by a swinging tree in the breeze.

Interval:

Click and move the slider control to the right to increase

interval time so that the alarm will only

be triggered when the movement lasts longer. Move to the left to reduce the interval.


Region Definition:

Define detection zone:

To detect Missing Object, you have to define a detection zone. Left-click and

drag the mouse to draw a detection zone. You may define more than one zone on the screen by
repeating the same process. User can also click on “All” button to select the entire detection zone.

Note:

For instance, if you want to prevent somebody from removing the computer monitor on the desk,

draw an area that fits the size of the monitor on the screen.
