Abstract: Doorbells can send data to each other to enable a first doorbell user to warn a second doorbell user regarding a suspicious visitor. A first user can indicate a first trait of a visitor via a first remote computing device. The first user can create a user group to enable the members of the user group to use their doorbells to take pictures of suspicious visitors and to send the pictures of the suspicious visitors to other members of the user group.

Abstract: Delivery parcel detection systems can include a doorbell having a first wireless communication system and a parcel holding system configured for placement in an entryway. The doorbell can be communicatively coupled to the parcel holding system. The parcel holding system can comprise a sensor configured to detect a delivery parcel located on the parcel holding system. Systems can include a first communication sent from the parcel holding system to the doorbell in response to the parcel holding system detecting an arrival, a movement, or a removal of the delivery parcel. Systems can also include a second communication sent from the doorbell to a remote computing device in response to the doorbell receiving the first communication.

Abstract: Delivery parcel detection systems can include a doorbell having a first wireless communication system and a floor covering configured for placement on an entryway floor. The doorbell can be communicatively coupled to the floor covering. The floor covering can comprise a sensor configured to detect a delivery parcel located on the floor covering. Systems can include a first communication sent from the floor covering to the doorbell in response to the floor covering detecting an arrival, a movement, or a removal of the delivery parcel. Systems can also include a second communication sent from the doorbell to a remote computing device in response to the doorbell receiving the first communication.

Abstract: Methods for using a doorbell chime system can include detecting, by a sleep detection system, that a person is asleep; receiving a first signal, by the doorbell or the doorbell chime, in response to the sleep detection system detecting that the person is asleep; and blocking the doorbell chime from emitting a first notification sound in response to detecting, by the sleep detection system, that the person is asleep.

Abstract: Methods for using a doorbell chime system can include detecting, by a sleep detection system, that a person is asleep; receiving a first signal, by the doorbell or the doorbell chime, in response to the sleep detection system detecting that the person is asleep; and blocking the doorbell chime from emitting a first notification sound in response to detecting, by the sleep detection system, that the person is asleep.

Abstract: Delivery parcel detection systems can include a remote computing device and a doorbell configured to detect a delivery parcel. The doorbell can have a wireless communication system and a radio frequency identification reader. The remote computing device can be communicatively coupled with the doorbell via the wireless communication system. The delivery parcel can have a radio-frequency identification tag. The doorbell can be configured to detect the delivery parcel by detecting the radio-frequency identification tag.

Abstract: A doorbell system can be configured to detect a weather event. The doorbell system can comprise a doorbell, a button coupled to the doorbell, and a pressure sensor coupled to the doorbell. As well, the doorbell system can determine an occurrence of a weather event and thereby transmit weather data to a remote server that is remotely located with respect to the doorbell system.

Abstract: Doorbell systems can include a doorbell having a speaker and a microphone. Doorbell systems can receive a custom message from a user. Doorbell systems can thereby detect an indication of a presence of a visitor, and then in response to detecting the indication of the presence of the visitor, doorbell systems can emit the custom message with the speaker.

Abstract: Doorbell systems can include a doorbell, a chime, and a remote computing device. In some embodiments, the remote computing device can select a sound. A data file comprising information that represents the sound can be sent to the doorbell that is communicatively coupled to the remote computing device. The doorbell can send the data file to the chime that is communicatively coupled to the doorbell and remotely located with respect to the doorbell.

Abstract: Doorbell systems can be configured to electrically couple to a doorbell power supply of a building. In some embodiments, the doorbell systems can include a doorbell with a button configurable to sound a chime. As well, doorbell systems can include a first wire that can electrically couple the doorbell to the power supply and a second wire that can electrically couple the doorbell to the chime. Doorbell systems can also include a third wire that can electrically couple the chime to the power supply to form a circuit comprising the first wire, the doorbell, the second wire, the chime, the third wire, and the power supply.

Abstract: Doorbells can include a speaker and a visitor detection system having at least one of a button, a camera, and a motion detector. The speaker of the doorbell can be configurable to emit a first sound in response to the visitor detection system detecting a first indication of a visitor's presence. As well, the speaker of the doorbell can be configurable to emit a second sound in response to the visitor detection system detecting a second indication of the visitor's presence.
