5.4 Creating/Editing a Task
A task is always created or edited using a wizard.
The following wizards are available:
– Section 5.4.2 Tampering, page 53
The camera is tampered with.
– Section 5.4.3 Flow in field, page 54
An overall movement (flow) is detected.
– Section 5.4.4 Counterflow in field, page 55
A movement against the flow is detected.
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.
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 the arrows whether a flow will trigger an
alarm with the given settings:
– Red arrow: alarm event will be generated.
– Yellow arrow: flow is detected, but an alarm event is not generated because of the filter
conditions.

5.4.1 Default Task
When you work with IVA 4.0 Flow for the first time, the default task Detect any flow is already
available. This task detects every flow in the entire camera image.
This first preset task corresponds in the configuration to the task type Flow in field (see:
Section 5.4.3 Flow in field, page 54).
5.4.2 Tampering
This task generates an alarm event if it must be assumed that the video source (camera) has
been tampered with.
Here, you can only activate the filter for the relevant events. You cannot alter the settings for
tamper detection. Only the settings from the standard configuration page apply.
An alarm event is generated if one of the activated events occurs (logical connective = OR).
– Scene too bright
Activate this function if tampering associated with exposure to extreme light (for
instance, shining a flashlight directly on the lens) should trigger an alarm. The average
brightness of the scene provides a basis for recognition.
