During the time window, the server 164 obtains contextual information from one or more sensors of the smart home environment 100, and determines whether an action from the visitor e. g. , a doorbell press, a door knock is detected within the time window. In accordance with an action being detected within the time window, a first type of response is initiated. Examples of the first type of response include sending a first type of notification to a user of a client device. In accordance with no action being detected within the time window, a second type of response is initiated. Examples of the second type of response include sending a second type of notification to a user of a client device. In some implementations, when the client device 220 loads the user mobile application 624 associated with the doorbell camera 106, the application 624 initiates a live video and/or audio connection to the doorbell camera, and allows video and audio information to stream within a predetermined duration of time e. g. Further, in some implementations, the user mobile application 624 displays an event list of events detected form the video and audio information received from the doorbell camera 106. Each event of the event list of events is represented by a thumbnail on a user interface of the user mobile application 624.
