Configure detection parameters
Video > VMD > Configuration
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).

Description
Enable VMD
Expands 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 TKH Security
software.
Global threshold high
VMD response
Fast or Filtered. Filtering is used to suppress a single peak as false
triggering.
