Hotel Ghost Caught On Camera?

This video shows what was allegedly recorded by a hotel security camera on August 21, 2012. The footage is being recorded a security responds to screams coming from an empty room. What happens next is creepy to say the least. Because of the lack of any back story, I am inclined to say that this is a fake, but a well done fake, without a doubt. The youtube user that uploaded the video, has other similar videos, many of which seem to contain genuine footage. Is this a genuine ghost video? You decide.
