I have a few questions for anyone who knows the answers, community, users of naturalpoint staff.

Question 1: Capture space and setup

I see that you can averagely get half of the rooms size worth of capture volume and have some questions about this.
I have a 24 foot long room that is 12 foot wide at one half and 9 foot wide at the other half.
This makes a 9x24 foot rectangle or a 12x12 foot square space.

I am thinking of using an 8 camera rig like the 8-camera tripod set-up example diagram.
In the 12x12 space that would give about six feet (Not a great deal of room to move), am I right?.
Now, would it be possible to use the same 8-camera tripod set-up in the 9x24 foot space and have a kind of oval or narrow walkway space around 4.5x12 foot, because this is room to move, all be it on a set narrow-ish path.

Question 2: Half body coverage camera's

I have seen this used with movimento using low FOV camera's, 2 at four points set so the top camera covers the head and most of the body and the bottom camera covers most of the torso enabling all points to be tracked at once at closer distances.
Would it be possible to increase the capture space using this kind of set-up?

Question 3: Lenses

If I where to use your camera's would I be able to use the higher FOV lenses you sell to get more capture space?

Question 4: Other Camera's

I know that MoviMento by RealViz, bought out by Autodesk can handle varying types of camera, lens distortion and resolutions because I have seen it used with Playstation Eye webcams at wide FOV lens mode, configured to run properly at 640x480 @ 60 fps, 320x240 @ 120 fps and 352x228 @ 90 fps with startlingly good results for the $30~ they cost.
Can USb camera's other than the ones sold by you (Using IR filters the Playstation eye performs well with crystal clear images at at constant fps when properly configured) be used with your software with such resolutions?

Question 5:

You sell ARENA Full body Mocap and ARENA Facial software,
are these simply specialised for there purpose requiring me to purchase both if I wanted to do both Full body and Facial mocap?

I await your response.

1 - Using the Tripods will actually use a little more of the setup volume, as the base would require them to be away from the walls slightly. The best setup would be a wall mount. The 24' might be a little long for a 8 camera setup, closer to 18-20, would be better.

2 - The best setup is to have as much overlap as possible, for initial testing, and setup, I would aim the cameras toward a single marker, in the middle at waist high.

3 - You could use the larger FOV lens, but there is larger lens distortion, so it is going to be a little more imprecise towards the edges.

4 - Only out cameras can be used with our software.

5 - The are different tool sets, and require different licenses to be able to access both sets.
