Netop Vision Pro is built on the same code base as Vision. At its simplest, it is a super-set of the Vision product. Vision Pro includes all the functionality of Vision, plus the ability to apply website block lists and the ability to remotely log on an entire classroom of computers from the teacher's computer.
Vision 8 made the hardware acceleration compatible screen sharing available to Vision users as well as Vision Pro users. Vision Pro bundles include Vision Mobile and Vision Learning Center licenses in addition to Vision Pro.
