Sensitivity
This setting relates to local detection levels: local change is only detected if its
level exceeds a certain value. The sensitivity setting can be used to eliminate
unwanted ('false') triggering (e.g. caused by background noise or constant local
movement).
Global threshold low
These settings relate to the summed amount of change within fully or partly
unmasked portion(s) of the screen; a value between the two thresholds gives rise
to a corresponding VMD alarm. The level of this alarm can be set (A-N) using
separate Siqura software.

. Filtering is used to suppress a single peak as false triggering.
