Size of the region
By dragging the lower right corner of the motion detection region you can change the size of
the region. The maximum size of the region can even be as big as the whole screen.
Sensitivity
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.
The biggest challenge of motion detection configuration is to find the settings that do not
produce false alarms and at the same time do not miss any actual intrusions. The rule of
thumb is:
the sensitivity should be as high as possible while not producing false
alarms.
The default sensitivity level of the cameras is 70 (on a scale of 0-100) and it is a
good setting for most standard cases.
