Mask allows to to
exclude part of the image on each of the cameras. It can be
accesses one of two ways, by
1. Clicking on
the cloud icon
2. via the
'Capture' drop down.
It works simply by
clicking on the image in the mask window and dragging a box to
create a selected area that will be excluded from the image.
You can customise
the area that you wish to have excluded by using as many click and
drag boxes as you want. You can also amend the masked area at any
time.
