It lets people watch their home or their offices on internet and using mobile devices whenever they want. This is a real-time system and users are warned by the system in emergency occasions like fire, water flood and thieves. The computer turns into a security system by adding the necessary software and hardware. BENEFITS OF PROJECT The HSS has lots of beneficial effects on society. Its social impact will be very important, because people far away from their home need not to be worried about it. People will be able to watch their home and give commands to the HSS by mobile devices. In the time of emergency they will be warned by the system by SMS and at that time the necessary process (calling police, fire brigade etc.) will be done by HSS. It is also very important for the police stations because the system will help them to determine the identity of the thief by using the database that the views are recorded. Briefly, the security need in the society is fulfilled. INNOVATION The original and innovative aspect of the project is watching home from internet and getting information by mobile devices. The system will alert when a problem occurs, so the user is warned by SMS. Also using the wireless technology is a new thing in security systems. The originality of the HSS is accessing the system by mobility like PDA or cell phone (using WAP) and the internet. SYSTEM ORGANIZATION In the system, the main software development environment is Java. Web processing applications are done by Java Server Pages and Servlets. For mobile applications, J2ME and WML is used. Database application is done by using Oracle. A microcontroller module is needed to provide communication between sensors and the main computer. Also a GPS modem is necessary to handle the mobile events. The HSS is including three types of sensors for detecting gas leak, water flood and open windows & doors. These sensors are cabled through the microcontroller module. Also the microcontroller is connected to the computer through the parallel port. The microcontroller gathers the signals from the sensors and converts them to digital. Then it sends them to the computer. Incoming signals are processed by the software on the computer. By the new data gathered, if there is an emergency occasion, corresponding actions including updating the website and WAP system, sending needed SMS and communicating with fire or police departments will be performed by the HSS. There are cameras connected to the computer via the tv-capture module that’s plugged on any of the PCI or USB ports. It will transmit the room view and it is always on. Figure 1 – The Structure of Home Security System – Hardware Structure PRINCIPLES OF OPERATION The user can log on to the internet with his/her password, watch the place and make the necessary changes (like mode changing). The system works in two different modes defined by the user. First mode is for the times when the user is at home .In this mode the user is not warned by the system by SMS; only the gas sensor and water sensor work. The image is uploaded by the software to the internet. Second mode is for the times that there is nobody at home. In this mode all of the sensors are on. If one of the sensors work, the main computer decides which sensor works from the microprocessor that is integrated to it. If it is a gas or water sensor, the system sends an SMS to the user; so the precautions can be taken in the beginning of the event. If it is a PIR sensor, it again sends an SMS. Also the image is began to be recorded to the database. This is for determining the identity of the thief. The demonstration interface of the main control software that we developed inception face of project process is shown in Figure 2. Figure 2 – A Demonstration View of the Main Control Software DESIGN STRATEGY The software process model used in HSS is Extreme Programming. We use pair programming principle of XP. Also we developed a coding standard in the team.

Figure 3 – Team Organization Chart OUTCOME At the end of the project, we expect to design a system that can be used at every home. If this system is used in the future, the number of people dying because of fire will decrease. The burglary occasions will not happen as frequent as today and the water flood will not happen; so the financial lost will be reduced.
