Videofied is a great solution for vacant properties because it requires nothing from the building itself- no power, phone line or internet connection! Since the Videofied system is portable, it can be relocated to new facilities if the building ends up getting sold or torn down. A prox tag can be left in the lock box for realtors to arm and disarm the system using the badge reader or it can be put on a 7-day schedule for auto arm and disarm.
