There probably isn't a school that has a course that teaches this as a
specific course.
Is you have some general knowledge in connecting low-voltage
electronics, can work well with your hands, and are willing to work your
way up, you may be able to get a job as a helper or apprentice at a
security installation company and learn as you work.
You should start with a few books on low-voltage wiring.
I don't have any specific titles, but look for books about telephone
wiring, computer networking, and secuity systems.
Good luck to you.
