City Tech's entertainment technology department has been presenting the "Gravesend Inn," a haunted hotel, for more than 20 years with annual attendance now typically around 6000. The system has evolved from the early days of manually operated systems and a few discrete control elements to a completely networked, modern, themed attraction featuring show systems while also leveraging surveillance technologies. This presentation will detail the history of the attraction and its technology, and offer a virtual behind the scenes technology tour.
