Does anyone know what this movie is called?

My friends told me about it. I think this is the plot or something around that. Its like the movie Quarantined with the way its film but different story. Its about 2 cops and some other guy with a camera and they get a call about some kind of disturbance from a house. So the cops go check it out the place and see whats going on. when they get there its really dark and supposedly no one is there. So the cameraman and the police officers go and look around and run into a vampire that lives in the house. And well they get attacked by the vampire and that's all I know. 1 of the cops is supposed to be like an newcomer while the other cop has been in the force for a long time and knows what to do. So does anyone now what it might be called. Its supposed to be a short film.
