object must cover to generate an alarm. This setting prevents
objects that are too small from triggering an alarm. A minimum
value of 4 is recommended. This value corresponds to four sen-
sor fields.
Global change %
You can define the percentage of sensor fields that must regis-
ter a change simultaneously before generating an alarm. This
setting is independent of the sensor fields selected under
Select area. This option allows you to detect, independently of
motion alarms, manipulation of the orientation or location of a
camera resulting from turning the camera mounting bracket, for
instance.

ment (by a tree in the wind, etc.), the relevant fields can be
deactivated.
