g. , a light ring can be controlled by the camera to display patterns that correspond to audible beats/rhythm of music or audio messages being played from the speaker in a range of colors selected to match the tempo/feeling of the music or audio messages. Providing such information via light patterns is advantageous as this is readily perceived by all/most users in the environment even if they do not have access to camera smart phone application without intruding on activity of occupants in the environment, as audible alerts could do sometimes. FIG. 5 illustrates a representative system architecture 500. In some implementations, the server system 164 includes functional modules for an event processor 3146, an event categorizer 507, and a user facing frontend 3150. The event processor 3146 obtains the event candidates e. g. , by processing the video stream, by receiving the event start information from the video source 501, or by detecting a user press on a doorbell button of a doorbell camera. In some implementations, the event candidates include motion event candidates. It is noted that the video source 501 is an example of the video source 222 shown in FIG.
