1. An electronic system comprising: at least one processor; and at least one non-transitory computer-readable storage medium coupled to the at least one processor having stored thereon instructions which, when executed by the at least one processor, causes the at least one processor to perform operations comprising: monitoring for events detected by a monitoring system located at a property; based on the monitoring, identifying at least one event detected by the monitoring system while the monitoring system is in an unarmed state; evaluating the at least one event based on inputs related to the monitoring system that include at least historical sensor data and current status of the monitoring system; based on the evaluation, assigning one or more abnormality scores to the at least one event, the one or more abnormality scores including an abnormality score for each event included in the at least one event detected by the monitoring system while the monitoring system is in an unarmed state; determining whether unusual behavior has occurred based on the one or more abnormality scores assigned; automatically updating, based on a determination that unusual behavior has occurred, one or more thresholds used in controlling the monitoring system to perform actions based on the at least one event detected by the monitoring system; performing an action based on at least the one or more updated thresholds and the at least one event detected; wherein assigning one or more abnormality scores comprises assigning multiple abnormality scores; and wherein determining whether unusual behavior has occurred comprises aggregating multiple slightly suspicious events in a short period of time to detect unusual behavior.
