Mode The zone mode identifies when the reference image is taken for
triggering VMD. The options are:
Normal - The reference image is updated
approximately 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
defined 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 defined zones from the image.
Default Grid (Yellow) Displays the default 16 zone grid across the whole image.
Refresh (Purple) Refreshes the information on the current page.
