Mode The zone mode identies when the reference image is taken for
triggering VMD. The options are:
Normal - The reference image is updated approx every
second. This will only allow small changes in the
scene without triggering
Last trigger - The reference image is only updated when
the VMD is triggered and is best used under
controlled lighting, i.e. so there are no false
triggers due to ambient light changes.
Static - The reference image is collected on startup
and is never updated. This would be used in
‘sterile’ areas where there are no changes
expected.
Zone disabled - This will disable the zone mode.
Pixel Count (%) This value is set as a percentage and equates to the percentage
of pixels in the selected zone that must change for the VMD event
to be triggered. The default setting is 20%.
Pixel Change (%) This setting is a percentage value of the overall change required
in the grayscale to be included in the pixel count. The percentage
change is dened over the complete range of black to white, a
100% pixel change would be from black to peak white. The default
setting is 20%.
Reload Image (Red) This will update the reference image to the latest view during
set up.
Clear All (Green) Removes all dened zones from the image.
Default Grid (Yellow) Displays the default 16 zone grid across the whole image.
