1. A control device for a premises security system that is configured to monitor a premises using a plurality of premises devices, the control device comprising:
processing circuitry configured to:
generate a trained acoustic model for the premises by at least:
obtaining a plurality of acoustic samples recorded at the premises, at least one of the plurality of acoustic samples corresponding to a location stamp indicating a location in the premises where the acoustic sample was recorded during a time window;
detecting a sound anomaly in at least one of the plurality of acoustic samples;
obtaining a verification that the sound anomaly is expected; and
training an acoustic model based at least on the plurality of acoustic samples and the verification that the sound anomaly is expected;
the trained acoustic model being generated based at least on the location stamp associated with at least one of the plurality of acoustic samples;
receive data representing a detected sound during monitoring of the premises;
compare the detected sound with the trained acoustic model for the premises to determine that the detected sound is unexpected; and
initiate a premises security system alert based at least on the detected sound being unexpected.
