IP Video System design tool offers same principles have been copied from early VideoCAD versions and simplified at many points.This simplification impairs accuracy. It can be compared with VideoCAD Lite and seems easier for mastering, but VideoCAD Lite is more physical exact and flexible. I think some skill level is needed to value this principal difference, not all user appraisals are correct. At the same time VideoCAD Lite is cheaper and can be upgraded to Professional at any time. VideoCAD Professional version is much more multifunctional, but for effective using all its capabilities good understanding of cameras, lenses, light...is needed.
