What I would like to see, and have confirmed is not available in the Dashboard, is the ability to show one or more de-warped "views" on the Video Wall. The virtual Pan-Tilt-Zoom is great, but if someone is monitoring a set of cameras, a human-friendly view(s) would be very useful.
For example: At a hallway intersection we install an MV32. Manually, we can select the camera and look down each hallway (North, South, East, West) with the usual motion search features, etc. On the Video Wall however, the camera looks like a sphere. My preference would be to select, from the Virtual PTZ view, a "scene" for each hallway that could then be added to the Video Wall.
