where can i earn education about security systems and home networking system?

like what kind of clases or what major in college shuld i take for that or is there any clases for that or not thanks

I don't believe this is something learned in higher education institutions... Knowledge in this area is earned by years of experience in security companies. You can and should make your first steps in the home security field on the web. For example, browse through Home Security Guru's hundreds of articles and guides - http://www.homesecurityguru.com
