The Telepresence Clinical Presence System (CPS) is a C40 video codec based mobile endpoint. It supports multiple screens, a motorized adjustable worksurface, and a number of inputs and outputs.

The VX Clinical Assistant essentially is the slighly smaller brother of the CPS. It is based on the C20 video codec, a smaller footrprint, has a single screen, and a stationary work surface.

Both mobile telepresence solutions are FDA class 1, and you can attach many of your video collaboration devices to our cart.
Clinical HealthPresence (to add some more confusion)is a much broader and larger scale type of solution. Video collaboration is a part of that, but also may contain medical devices, scheduling, data and record aggregation, automatic calling ,etc. used mostly in larger network deployments.
Hopefully that can clarify things a bit.
