This video went up yesterday, was pulled down and then restored later for some reason (not before other youtube users posted their own copies and gathered many more views than the official channel)
The video states 30Hz, and there is an interesting shot starting at two minutes.
From the above screenshots it's possible to count the number of pixels horizontally and vertically, and also most of the depth bins (there may be more range beyond the wall behind the person but a minimum count is better than nothing).
So there at least 18 depth bins, counted at 2:01-2:04 in the video. Each is maybe 2 or3 inches spaced.
The resolution looks like 64x64.
