SYSTEM AND METHOD FOR ENHANCING SECURITY FUNCTION THROUGH DOUBLE MONITORING
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.
Provided are a home security system capable of detecting a trespass position or time as well as detecting whether or not a trespass occurs, via a unique identification (ID) assigned for each trespass detection sensor via a power line communication, and a home security method thereof. The home security system includes a number of sensor units which produce packet data indicating occurrence of abnormal situations when the abnormal situations occur, and attach the data packet with a neuron identification (ID) being a unique identification (ID) which is sensor installation position information, to then be transmitted via a power line, and a home controller which operates a security system according to manipulation of a user, receives the packet data transmitted via the power line from the sensor, analyzes occurrence of abnormal situations, and grasps a trespass position and a trespass migration path through the unique identification (ID). Thus, if abnormal situations such as external trespass occur, a trespass position, path and time can be confirmed to thus further enhance a home security performance.
