Example: At 90 % the second picture would have to differ very
greatly from the first picture for an alarm to be triggered.
However, a change in the picture information of more
than 90 % will only occur very seldom.
This setting can be called relatively insensitive. There
will be few (false) alarms. A alarm will not be triggered
until the camera is turned.
A limit of 20 % can be viewed as a sensitive setting. A
change in picture information of more than 20 % can
occur very quickly, e.g. due to a person walking through
the picture. So an increased number of alarms or false
alarms will occur.
General guide values for sensitivity
20 % = sensitive/many alarms
70 % = average
90 % = insensitive/few alarms
