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.
