Calibration
If you wish to filter out objects according to their size or speed,
for each camera position a link must be made between the size
of the real-life situation and the dimensions as they appear on
the camera image. For example, you must tell the software that
an object that appears on the camera image with a height of
50 pixels is around 2 m high in reality. The camera angle is used
to compute object speeds. The calibration mode is available for
this operation.
Filter hierarchy
Below is an overview of the filter methods. You will find a
description of the filters in the following sections.

NOTE!
Display of measurements can be adjusted, so that when using
the English software interface imperial measurements are
shown. You will find additional information in Section 5 Display
of Measurements, page 38.
Sensitive area Objects outside the sensitive area are
ignored.
Global settings Objects that are smaller than the min-
imum size setting or larger than the
maximum size setting are ignored.
Detector field Only objects with their center (center
of gravity) inside the detector field
are detected.
Properties
of the detector field
Objects are filtered out based on
their properties. Different properties
can be defined separately for each
detector field.
