4.5.8 Removed object
This task generates an alarm event if an object is detected as removed in a certain area (for
example, due to theft). The area is defined by a field in the camera image.
It is assumed that an object has been removed if changes are detected in the background
following movement within an image.
First Step - Define the Field
X Select one of the fields.
To do this, use the list field or click a field in the camera image.
You can also create a new field, edit an existing one or select Whole screen.
Next Step - Approximation
You can impose approximations for the different object properties. You can adopt these
values as the basis for the settings in the next step.
These settings are described here: Section Next Step - Approximation, page 24.
Next Step - Define the Conditions
You limit the number of objects that trigger an alarm event by precisely defining properties
such as size, aspect ratio, speed and direction.
These settings are described here: Section Next Step - Define the Conditions, page 25.
Final Step - Define the Color
You limit the number of objects that trigger an alarm event by defining the color properties
more precisely.
These settings are described here: Section Next Step - Define the Color, page 28.
4.5.9 Idle object
This task generates an alarm event if an object is detected as idle or inserted in a certain area
(for example, a piece of luggage without an owner). The area is highlighted by a field in the
camera image.
First Step - Define the Field
1. Select one of the fields.
To do this, use the list field or click a field in the camera image.
You can also create a new field, edit an existing one or select Whole screen.
2. Debounce time [s]
This entry is adopted from the global settings.
Next Step - Approximation
You can impose approximations for the different object properties. You can adopt these
values as the basis for the settings in the next step.
These settings are described here: Section Next Step - Approximation, page 24.
Next Step - Define the Conditions
You limit the number of objects that trigger an alarm event by precisely defining properties
such as size, aspect ratio, speed and direction.

Final Step - Define the Color
You limit the number of objects that trigger an alarm event by defining the color properties
more precisely.
