12. A monitoring system that is configured to monitor a property, the monitoring system comprising: a monitor control unit; and one or more sensors that are located at the property, and are in communication with the monitor control unit, wherein the monitor control unit is configured to: obtain historical event data for events detected over a past period of time by sensors within a property; receive a set of current event data for one or more events detected by one or more of the sensors within the property; determine that the set of current event data matches a pattern of events indicated by the historical event data; generate, based on the pattern of events, a confidence score for the set of current event data that indicates the likeliness that a person is not within the property; determine, based on analyzing a cost for performing an action and a convenience to a resident of the property for performing the action, a confidence threshold for the action; compare the confidence score for the set of current event data to the confidence threshold for the action; based on comparing the confidence score for the set of current event data to the confidence threshold for the action, determine that the confidence score satisfies the confidence threshold; and in response to determining that the confidence score satisfies the confidence threshold for the action, perform the action.

The system of claim 12 , wherein generating, based on the pattern of events, a confidence score for the set of current event data comprises: generating a confidence score that reflects a low confidence that a person is not within the property when it is determined that a more definitive set of event data will be received within a short period of time.
