That video seems to have confused what Xaver do with technology more from a
Star Trek episode.  The smaller units give you a blurry blob of what's
probably a person in a room.  The larger units, which are anything but
unobtrusive, give you slightly better imaging, but it's still mostly "there is
probably a person at this location in the room".  If you look at Xaver
advertising it's either lots of footage of ninjas with automatic weapons
running around or an emphasis on how much data they feed you (graphs, images,
animations) without really convincing you that it's terribly useful beyond
"probable person at this location" - some of the stuff looks like MRI imaging
of a postmortem Atlantic salmon.  It's main practical application seems to be
locating people in burning buildings.
