Poor Man's Security System 2

Electronics project. Second prototype of a security system which recognizes when a door or window has been breached and gives the homeowner 30 seconds to type in a code to disable the alarm before a loud secondary alarm kicks in.

What happens if the burglar opens the box and cuts the speakers off?

[patrickikis]

@davesnipe360

Well, I guess I'd be screwed. However, this was just a project I made in school. Secondly, if I were sleeping, I would likely hear the pre-alarm from the Piezo =)

[patrickikis]

Probably... I could place a crowbar circuit at the output to counter that; setting off the alarm the instant an over-voltage surfaced.
