Intelligent Video
The Intelligent Video section allows users to configure the built-in
analytics of the camera. Features may vary depending on the camera model.
Motion Detection
The Motion Detection sub-section allows users to configure the video motion detection system
of the camera. Up to 10 different regions covering the whole camera view can be configured for
motion detection based on Stream 1. By default, the whole camera view has been enabled as
Region 1.
Sensitivity is the parameter that helps us distinguish actual moving targets (people, vehicles)
from the slightly moving background, such as leaves of the trees waving in the wind. In order to
avoid false alarms, we might want the camera be able to ignore small motion. The higher is the
sensitivity level of the camera, the smaller shift of the object is needed to trigger the alarm. For
example, if the object within motion detection region has moved for about 1-3 pixels during two
video frames, then such small motion will be discarded by camera if the sensitivity is low, and will
still trigger an alarm if the sensitivity is high. In other words, you can think of sensitivity level as a
reversed speed limit – the smaller is the sensitivity, the faster are the objects allowed to move
without being detected.
