3. Operators can set a time at which the intelligent home security alarm would be armed, disarmed, or enter the Armed Stay state.
4. Up to 3 people can be notified of a reported alarm via SMS messaging or phone call. To do this, users need to put 3 groups of text messages and mobile phone numbers into the GSM alarm beforehand.
5. Operate the remote controller to either arm or disarm the alarm. During both processes, the external siren would go off to let operators notice that the wireless alarm has been activated or switched off. This feature solves the problem of being unable to hear the low humming sound produced by the alarm module when users stand at their doorway. When not in use, the siren can be shut off.
