  • Patent number: 7956739
    Abstract: A monitoring and entry system presence service provides notification about a trigger event to a user and performs actions based on user input. Interface devices equipped with client applications capable of performing actions such as VoIP calls, video calls, and the like, register with a control and session layer, which facilitates interaction with a specific presence application and an integrated presence service, such as a doorbell application and a generic presence service. Upon determining the location of a user, notification and a list of actions are provided through a watcher client application. In response to the user selection, actions are facilitated through the same network session(s).
