  • Publication number: 20200280701
    Abstract: A system for electronic monitoring includes a doorbell configured to immediately call a user following the occurrence of a trigger event, such as a doorbell button push or detection of motion or sound. The system reduces latency by omitting push notifications to the user, which require the user to open an application program on a device, and instead proceeds to immediately call the user's device following the trigger event. The call can be a telephone call enabled by a wirelessly connected base station or hub making a Voice over Internet Protocol (VoIP) call to the user's mobile device. In one aspect, a video stream captured by a camera positioned separately from the doorbell (for providing an optimum viewing angle of a visitor) can be synchronized by the base station with an audio stream captured by a microphone of the doorbell for communicating a synchronized media stream near instantaneously to the user while the user returns an audio stream to the doorbell during a phone call.

  • Publication number: 20200280702
    Abstract: An electronic doorbell system can be configured to allow simultaneous video and audio communication to a user on a computing device in which the video is provided by a camera that is selected from among multiple available cameras provided at different locations, while the audio is provided by a microphone of the doorbell system such as a microphone associated with the doorbell or a selected camera. User input can allow selection of one or more cameras. When multiple cameras are selected, the system can take an audio/video feed from the cameras in predetermined sequence or random sequence based on events observed by the system The camera could be selected by default, based on user input, and/or automatically using artificial intelligence. Selection by artificial intelligence could comprise, for example, selecting a camera based on a detected motion and/or sound, a captured image matching a predetermined image and/or a captured sound matching a predetermined sound.

  • Publication number: 20200279459
    Abstract: An electronic doorbell system can be configured to enable remote audio communications between a visitor at the doorbell and a user of a mobile computing device by exchanging speech-to-text and/or text-to-speech messages in real time. Audio captured by the visitor can be transcribed into text messages and sent to the user of the mobile device using a speech-to-text service. The user of the mobile device can send text messages to the doorbell for playback to the visitor by using a text-to-speech service. The system can also use artificial intelligence to detect the language spoken by the visitor for translating between a predetermined language of the user and the language of the visitor. The system can also include a camera for capturing video of the visitor for display to the mobile device simultaneous with exchanging text messages between the visitor and the user, such as during a live Session Initiation Protocol (SIP) communication.
