1. A monitoring system comprising one or more computers and one or more storage devices on which are stored instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
maintaining, in memory, a plurality of first acoustic signatures each of which (i) represents a different pre-programmed acoustic signature representing a knocking pattern and (ii) has corresponding permissions that indicate allowed actions and an action criteria for performance of the action, at least a first permission for a first maintained acoustic signature from the plurality of first acoustic signatures indicating different allowed actions than a second permission for a second maintained acoustic signature from the plurality of first acoustic signatures;
receiving knock data that (i) was captured by a microphone and (ii) encodes a second acoustic signature representing a knock;
determining whether a similarity between any of the first acoustic signatures from the plurality of first acoustic signatures and the second acoustic signature satisfy a similarity criterion;
determining, as a matching first acoustic signature, the first acoustic signature for which the similarity criterion with the second acoustic signature is satisfied;
after determining the matching first acoustic signature, accessing the permissions for the matching first acoustic signature, the permissions indicating different allowed actions than other permissions for a different acoustic signature;
in response to determining the matching first acoustic signature, determining whether data for the knock data satisfies an action criterion for the permission for the matching first acoustic signature; and
in response to determining whether the data for the knock data satisfies the action criterion for the permission for the matching first acoustic signature, performing a monitoring system action for the permission using data for the matching first acoustic signature.
