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%.
Global Activity Mode
This is set to Always Active when VMD is enabled.
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 current page.
