10.4.6.2 VMD Configuration 1: Detection Parameters
VMD enabled: Configuration section with controls, video picture, and motion detection inset, the latter
with mask applied. The mask permits motion detection in the right half of the picture only, at the top of the
stairs, so passers-by and cars would not be registered by the detector facility; neither will the details in the
background (the trees are reflected in the window pane though, and this could be masked separately).
Configuration
Enable VMD Select this box to expand the Configuration section, as shown in the above figure.
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.
Global threshold high
VMD response Fast or Filtered . Filtering is used to suppress a single peak as false triggering.
