While I DO believe that there is a very strong possibility that there are some spirits wandering around DL, I don't believe this one. Why would someone who has access to those security screens have a video camera? Why would that person (presumably at work) record security footage? Why would that same person (again, presumably at work) upload the footage to the internet, when s/he probably isn't supposed to have video'd it to begin with? Too many pieces of the source don't fit for me.
But it's fun to watch!
