Decision Process For perimeter modules a USB format webcam was selected for perimeter cameras and a USB relay board was selected for the communication pathway between the access module and control computer 3 0 Basic Solution Description As outlined above the purpose of this project was to create a security system that would be independent of a security company This would allow the owner of the business to have more control over the monthly financial costs of the security system Since this was going to be a security system controlled by the business owner we decided to use the PC Personal Computer as the control center for the security system Since the PC is a common tool available to nearly every business owner it would allow us to keep the costs down Since we decided to use the PC as the center of the security system we chose to use the USB Universal Serial Port to interface with the peripherals for the security system Although this technology is not new by computer standards it has proven itself to be a viable communication medium due to its widespread usage which has resulted in the USB being an industry standard in PCs However one of the drawbacks that we had to investigate before we could proceed was a distance limitation with the interface USB cables have an effective range of about 15 feet This raised significant problems as the components the computer would need to communicate with would be three to four times this dis
