As an example, a sound of “Please come” is emitted from the outdoor door phone 11, and a high level signal is output from the monitoring terminal of the JEM-A terminal 10a (see FIG. 4). Therefore, the user can confirm that the outing mode has been set.

  FIG. 5 is a flowchart showing the operation of the IT home gateway 2. In FIG. 5, when a high level signal is output from the monitoring terminal of the intercom device 10 (S1: YES), the IT home gateway 2 determines that the outing mode is set and starts an abnormality monitoring operation (S2). ). In this abnormality monitoring operation, it is monitored whether the notification of state change information has been received from the network home appliance 6 to be monitored (S3) or whether the high level signal from the monitoring terminal of the intercom device 10 has been stopped (S4).

  Now, during such an abnormality monitoring operation, if a suspicious person enters the room through a window and passes near the proximity switch 6b2 of the lighting 6b installed in the living room, the proximity switch of the lighting 6b reacts. The illumination 6b is turned on. When the lighting is turned on, the lighting system notifies the IT home gateway 2 of the state change information (lighting).

  When the IT home gateway 2 receives state change information (lighting) from the lighting system during the abnormality monitoring operation, the IT home gateway 2 determines that an abnormality has occurred, and sets an abnormality in the mail address of the user's mobile phone 13 registered in advance. Send an email to indicate. Therefore, when the user confirms the mail transmitted to the mobile phone 13, he / she contacts the security company or returns home from the outside to respond quickly.

  On the other hand, when the user who returns home inserts the key into the electric lock 9 and rotates from the locked position to the unlocked position, the high level signal output from the monitoring terminal of the intercom device 10 stops (see FIG. 4). The IT home gateway 2 determines that the user has returned home (S4: YES), and ends the abnormality monitoring (S5). Therefore, after that, even if the operation state of the network home appliance 6 to be monitored changes, the IT home gateway 2 does not determine an abnormality.

  According to such an embodiment, the IT home gateway 2 starts an abnormality monitoring operation when the outing mode is set, and when a state change occurs in the network home appliance 6 during the abnormality monitoring operation, Since it has been determined that the error has occurred and the user is notified of this, a crime prevention system can be constructed using the network home appliance 6. Therefore, since the occurrence of an abnormality can be detected without providing a special sensor, a crime prevention system can be easily constructed and the added value of the network home appliance 6 can be increased.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows.
The abnormality judgment based on the change in the state of the network home appliance 6 can be performed by changing the operation of various network home appliances.
