Premises monitoring using acoustic models of premises

A method implemented by a control device for a premises security system that is configured to monitor a premises using a plurality of premises devices, the method comprising:

• generating a trained acoustic model for the premises by at least:
• obtaining a plurality of acoustic samples recorded at the premises;
• 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 at least by incorporating, into the acoustic model, at least one verified acoustic sample comprising the sound anomaly in response to the verification that the sound anomaly is expected;
• and
• implementing the trained acoustic model for monitoring the premises, the trained acoustic model comprising at least one unverified acoustic sample and the at least one verified acoustic sample.

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:

• at least one processor;
• and
• at least one non-transitory computer-readable medium storing a plurality of instructions that, when executed by the at least one processor, cause the at least one processor to:
• generate a trained acoustic model for the premises by at least:
• obtaining a plurality of acoustic samples recorded at the premises;
• 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 for the premises based at least on the plurality of acoustic samples and the verification that the sound anomaly is expected, the training comprising incorporating, into the acoustic model, at least one verified acoustic sample comprising the sound anomaly in response to the verification, the trained acoustic model comprising at least one unverified acoustic sample and the at least one verified acoustic sample;
• determine that the trained acoustic model for the premises indicates that a particular sound is expected in the premises;
• determine that the particular sound has not been detected during monitoring of the premises;
• and
• initiate a premises security system alert based at least on the particular sound not being detected during monitoring of the premises.
