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: 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.
