When you use the wizard to create or edit a task, you have access to the camera image and
the popup menu. This means that you can create, edit or delete fields, lines or routes.
In Configuration Manager, the camera image with the popup menu is directly integrated into
the IVA 4.0 window. When configuring in the Web browser view, you use the preview on the
VCA configuration page.
You can immediately recognize from the color of object outlines whether an object will trigger
an alarm with the given settings.

4.5.1 Default Task
When you work with IVA 4.0 for the first time, the default task Detect any object is already
available. This task detects all objects in the entire camera image. Initially, even the global
settings are preset in such a way that no object is excluded.
This first preset task corresponds in the configuration to the task type Object in field (see:
Section 4.5.2 Object in field, page 24).
4.5.2 Object in field
This task generates an alarm event if an object moves within a certain area. The area is
defined 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]
If a value other than 0 (zero) is selected, the alarm event will not be generated until the
object has moved or been within the field for the specified period at least.
By entering a value, you can prevent the triggering of multiple alarm events by objects
that are constantly moving toward and away from the boundary of the field.
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.
