4 Area settings
4.1 The basics
The camera 'sees' a selected area that is displayed as a single,
constantly refreshed image.
Objects
Objects are typically people or vehicles moving within the area
seen by the camera. Objects can be filtered according to cer-
tain properties (size, direction of movement, speed, location).
An alarm event can be generated if objects match certain
parameters. Objects that do not match the criteria you define
are filtered out and do not generate an alarm event.
It is always the center of an object that is relevant for generat-
ing an alarm event.
Detector fields
Detector fields are polygons that cover a certain area, for exam-
ple an entrance or the open space in front of a barrier. These
detector fields are defined by you. Moving objects that are out-
side the detector fields will be detected as such but will not
generate an alarm event. Objects that move inside detector
fields or across detector field boundaries (depending on your
settings) will generate an alarm event.
Sensitive area
The scene that is captured by a camera often includes areas
that are irrelevant for alarm event generation (such as sky).
You can reduce the size of the area that is actually analyzed for
motion. This will make motion detection for the remaining –
sensitive – area all the faster and more effective.
