Mode
The zone mode identifies 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 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.
