The system responds to a keypad and/or communications from a public switched telephone network to present the images for viewing. A system according to the invention supports visual verification of false alarms, tracking of arrivals and departures and recording those who arm and disarm the system. Visual verification also can be used in connection with remote notifications or authorizations of entry to the secured area.
