Route
Objects that move along a route you have defined in a pre-defined direction can trigger an
alarm event. It is possible to include deviations from this route using the relevant tolerance
defaults.
Color
The color properties of an object are mainly used in forensic searches to detect moving
objects by their color. As objects rarely appear in one single color, the colors are detected by
analyzing the different proportions of color according to their frequency. This means that, for
example, you can search for objects that consist of up to 25% dark red pixels but also include
up to 20% light gray pixels at the same time.
Color properties used for filtering can be adopted and refined using a marked object.
Task
Tasks are the central control element in the IVA 4.0 setup. The aim of a task is to generate an
alarm event in precisely defined situations.
A task can be created using a wizard. Expert users can adapt tasks created in this way to
individual requirements using additions in the script.
Tasks can be activated or deactivated at any time.
You can define up to eight tasks.
Wizard
To make it easier to create and edit tasks, certain tasks have wizards that guide you through
the creation of a task in a few steps. During this process, you are asked to define all of the
parameters required for the task.
Filter Hierarchy
IVA 4.0 offers a series of filter options so you can adapt the analysis to your requirements. You
exclude certain objects or areas from the analysis in order
– to avoid false alarms
and
– not to increase the computing power of the device unnecessarily.
Here is a schematic overview of the various options for restricting the number of alarm-
triggering objects.
NOTICE!
You can create up to 16 fields, 16 lines and 8 routes (as routes are counted twice). The total
sum of these items cannot be greater than 16. If this limit is reached, no additional items can
be created.
NOTICE!
The detection of color is not possible for objects that are only displayed with very few pixels.
