<p>A system and method for enhancing a security function through double monitoring notifies a user of whether an abnormal situation has occurred even in the case that a home controller does not judge whether an abnormal situation such as door lock opening and trespass detection has occurred, due to an abnormality of the home controller, power failure or a power cut-off to the home controller, to thereby provide an effect of improving reliability of a security. When the opening event of a door by a digital door lock occurs or external trespass is sensed by a sensor mounted in a house, the home controller in which a crime prevention mode is preset checks if a security mode has been released within a preset time, and simultaneously notifies an external management server of the opening of the door lock and trespass detection, to thus make the management server check if the security mode has been released. Accordingly, even in the case of the abnormality of the home controller or the power cutoff to the home controller, the management server judges that an abnormal situation has occurred if there is no signal stating a security mode has released, and notifies a user's cellular phone that the abnormal situation has occurred using a short message service (SMS). Therefore, even in the case of an abnormal situation where a door is abnormally opened or an undue trespass occurs through other routes, and thus the home controller does not operate due to an abnormality of the home controller or a power cut-off to the home controller, the management server can generate an alarm and notifies a user that an abnormal situation has occurred, to thereby improve a reliability of a security function in the house.</p> |
