Have you thought about installing a home security system, but put it off because you don't think you really need one? Well, before you put it off any longer, you may want to consider these facts: In 2010, there were more than two million home burglaries in the United States, over 70 percent of which took place in residential homes, reports the Federal Bureau of Investigation (FBI). Victims of these burglaries claimed an estimated $4.6 billion in lost property, and the average dollar loss per burglary was $2,119. With these startling statistics, investing in a home security system doesn't seem like such a bad idea. The number one reason to invest in a home security system is to protect your family and many other things. In this report we will show the steps as well as the design of home security system.
Abstract
This project will show how to use PLC to design and execute a home security system that sounds an alarm and calls the police or fire department when a burglar breaks in, or in case of smoke or fire detection. A brief introduction to PLC will be explained, as well as the hardware and software of the security system.
A physical model and steps of building the security system will be discussed as well as its set up and mode of operation. System testing showed a quick and efficient operation of the system, where in case of smoke or fire detection, light and siren are triggered and fire department is called, and in case of break-in police is called as well as siren is triggered.
