GUESS WHOSE PUNCHLINE WAS INSTANTLY OBVIOUS <| sep |> Apparently he was on a list of possible Clinton VPs I ' m sure he checked a certain box . but I think they realized he has never really accomplished anything in SA or in HUD . Or maybe it could be the fact that they decided that they thought Kaine was the best choice and that Castro and the rest were still perfectly reasonable candidates . Not being picked for a VP position doesn ' t make you worthless . <| sep |> No dash would have made it absolutely genius . just kidding . <| sep |> At minimum you ' re going to need PoE wiring to every door for the readers , power to each lock solenoid , a PoE network switch , a router , and a computer or blade server with the central access control software running the whole thing . It ' s not a job for amateurs . The readers alone are easily $ 100200 each . Every ProxCard or HID card will cost $ 1020 . Every checkpoint will take a professional about 2 man hours per door to install and that ' s assuming he has locksmithing talent . For safety reasons , the solenoids are designed to open when the power goes out . You never want people trapped inside the building simply because your security system failed .
