Is that a ghost in the window?

Looks like for my first blitz I'm going way back to 2006, looks like I'll going that far back for a little more, gotta clean my bookmarks out.

Looks like this video is from sort of paranormal investigation team or some hoaxers.

Their in front on some old building at night filming into windows, they keep saying they all see something but I can't make anything out, though at about the 1:11 mark there is a very noticible flash from the very top window, looks tricky to me though.
