A multiple dwelling house interphone system includes a communication management device that controls communication between the collective entrance machine and the mobile phone. The communication management device relays the communication to the mobile phone registered as a calling destination of the collective entrance machine to be linked to the dwelling room master device using a predetermined application based on a VOIP. When a predetermined registration operation to allow communication with the communication management device based on the VOIP is performed to link the mobile phone to the dwelling room master device, information list on mobile phones already registered relative to the dwelling room master device as a link target is transmitted from the communication management device having accepted the registration in addition to an application for a download, and the mobile phone that has downloaded the application displays the information list on a display section of the mobile phone.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing targeted notifications. One of the methods includes determining a likely identity of a visitor who arrived at a property that is associated with two or more people, selecting, from the two or more people, a target person using the likely identity of the visitor, and sending, to a device of the target person, a notification that indicates that the visitor arrived at the property.

A conversation augmentation system can automatically augment a conversation with content items based on natural language from the conversation. The conversation augmentation system can select content items to add to the conversation based on determined user “intents” generated using machine learning models. The conversation augmentation system can generate intents for natural language from various sources, such as video chats, audio conversations, textual conversations, virtual reality environments, etc. The conversation augmentation system can identify constraints for mapping the intents to content items or context signals for selecting appropriate content items. In various implementations, the conversation augmentation system can add selected content items to a storyline the conversation describes or can augment a platform in which an unstructured conversation is occurring.

Doorbells often include a button to enable visitors to ring a chime to summon building occupants. In some embodiments, doorbells include a camera to take pictures of visitors. In several embodiments, doorbells include covers that are light filters. These light filters can cover infrared light sources such as infrared light emitting diodes. The light filters can pass infrared light while blocking visible light. In several embodiments, a front portion of a camera assembly fits through a hole in a light filter. Light filters can help secure camera assemblies and can form a portion of a doorbell's outer housing.

Doorbell systems can include a doorbell and a remote communication device. In some embodiments, the remote communication device can be communicatively coupled to a wireless network of a building, to the doorbell, and to a remote computing device. In several embodiments, the remote communication device facilitates communication with at least one of the doorbell, the remote computing device, and a remote sensor.

The disclosure includes a method for using a doorbell system to detect a presence of a visitor. The doorbell system can comprise a doorbell having a speaker, a microphone, a camera, and a button. The method can include detecting, by the doorbell system, the presence of the visitor while the visitor is located outside a building to which the doorbell is attached. The building can include a door having a lock that is configured to fasten the door to inhibit unauthorized entry into the building. In response to detecting the presence of the visitor, the method can include the step of actuating, by the doorbell system, a first appliance associated with the building.

An audio-video communication system comprises a wireless exterior module located proximate an entrance, a computerized controller running a software application, and a remote peripheral device. The wireless exterior module includes a proximity sensor for detecting a person at the entrance, a video camera for recording an image of the person at the entrance, a microphone for recording the person at the entrance, a speaker for playing audio to the person at the entrance, a transmitter for communicating sounds and images of the person at the entrance, and a receiver for receiving communications at the wireless exterior module. The computerized controller is disposed in wireless electronic communication with the wireless exterior module via the transmitter and the receiver of the wireless exterior module. The remote peripheral device is configured to electronically communicate with the computerized controller for viewing an image from the video camera communicated from the wireless exterior module.

Doorbell systems can include a doorbell and a chime. In some embodiments, the chime can be communicatively coupled to a wireless network of a building, to the doorbell, and to a remote computing device. In several embodiments, the chime facilitates communication with at least one of the doorbell, the remote computing device, and a remote sensor.

Doorbell systems can include a speaker and a visitor detection system that includes at least one of a button, a camera, and a motion detector. Doorbell systems can be configured to detect an identity of a visitor via facial recognition, initiate a communication session with a remote computing device, and send the identity to the remote computing device via the first communication session.
