The project aimed to prevent theft cases and intrusions at home by using wireless technology. The system consisted of an IP camera, Arduino microcontroller, GSM shield, Ethernet shield, electronic door strike, transistor, FSR sensor, wireless router and mini pocket router, alarm device, PC unit and Android mobile phone. The IP camera was used for surveillance and for detecting the face of a person nearby. A website was designed to monitor the activities outside the house via live stream and store the images and logs. The Gizduino X is an Arduino compatible board, which served as the microcontroller of the system. It was connected to a GSM shield which allowed the system to send a SMS, and to an Ethernet shield which allowed the microcontroller to communicate through Internet. The FSR sensor was connected to the electronic door strike to detect if there was an intruder and to trigger the alarm device. When the face detected was not authorized to enter the house, the system sent a notification message to the homeowner, and when the door was opened forcibly, the system automatically sent a notification message to the homeowner as well as to the police. An Android mobile application could control the door lock and monitor its status. The user had three options in controlling the door lock, with the use of IP camera, Android mobile phone and manual key. When one of the components malfunctioned, there would still be another option to unlock and lock the door.
