hi to all! i'm a graduating computer engineering student and i need some help regarding my thesis. what me and my group is planning is to make a security system. it works like, if there is an intruder at your house, automatically it will alarm (i guess after touching a sensor) and the telephone line will automatically call the police or even your cellphone saying that someone's at your house. can you help me on that, what are the necessary things to consider in building that system and what program or materials i need to complete our thesis. tnx.. :?:
