Abstract
Methods, systems, and apparatus for door knock access control are disclosed. A monitoring system for monitoring a property includes: a proximity sensor located at a door of the property; a microphone that is configured to detect sound within an area near the door and generate audio data that represents the detected sound; and a monitor control unit configured to perform operations including: receiving, from the proximity sensor, proximity data indicating an object positioned within a set proximity to the door; based on receiving the proximity data, activating the microphone; receiving, from the microphone, the audio data; determining that a similarity between the audio data and stored audio data representing a knocking pattern satisfies similarity criteria; and in response to determining that the similarity between the audio data and the stored audio data satisfies similarity criteria, performing a monitoring system action.
