Home-made alarm system device website

(OP)
CAn you please tell if there is a website where I can find a diagram to build a home-made alarm system? There may also be a kit to build. What is a cost-effective solution based on, diaphragms, infrareds, motion detectors?
Thanks for the info.

RE: Home-made alarm system device website

Are you look to build an entire system or just the main control components? To be honest you can normaly purchase security components (i.e motion sensors, door contacts ect) from a security wholesale company for a fraction of the cost of a pro install.These are the companies most security contractors buy from. I don't know any websites but I hope this helps.
