Abstract: Various embodiments of systems to detect the presence of intruder devices in home environments are disclosed. The system includes a home hub positioned proximate to a home; a security sensor positioned proximate to the home and communicatively coupled to the home hub; a transceiver, and a control circuit communicatively coupled to the home hub, the database, and the transceiver. The security sensor detects security events associated with the home and transmits notifications of the security event to the home hub. The control circuit is configured to: receive trigger events when the home hub receives the notification; in response to receiving the trigger event, capture wireless traffic; determine whether the wireless traffic includes unknown device identification information; and generate another notification when the wireless traffic includes the unknown device identification information, the other notification includes the unknown device identification information.
