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.

A monitoring system that is configured to monitor a property is disclosed. The monitoring system includes a sensor that is configured to generate sensor data that indicates an attribute of the property; a floor sensor that is configured to generate floor sensor data that indicates an amount of pressure applied to a portion of a floor of the property; and a monitor control unit. The monitor control unit is configured to receive, from the sensor, the sensor data; receive, from the floor sensor, the floor sensor data; analyze the sensor data and the floor sensor data; and based on analyzing the sensor data and the floor sensor data, perform a monitoring system action.

Techniques and systems are described for creating and operating a vibration triangulation network. The network can include vibration sensor devices placed in a building, such as a store or a house, which are able to pinpoint the location of a target, e.g., person, animal, etc., through triangulation. A described technique includes receiving vibration notifications from vibration sensor devices, determining a location of a target within the building based on at least a portion of the vibration notifications and a vibration sensor map associated with the building, and triggering an alarm event based on a detection of the target.
