A difference between Ceiling- and "Desktop-"Visualizers is that the size of the smallest and largest image
the unit can pick up is not fixed. This depends on how high above the working surface the Visualizer is
mounted.
It is very important to know which image sizes you would like to pick up with the Ceiling
Visualizer before installing the unit,
in order to correctly calculate the respective mounting height.
Please refer to the calculation program on WolfVision's homepage
(see page 5)
.
