Brainstorming- Room Security in a Shared College House
I'm soon to be moving into house with 3 total strangers. My door I know, will have a standard lock and key. If anyone there knows ha;f as much as I do, as I'm sure you all know as well, it would be not-so-hard to break in, if someone ever felt the need to do so.
My question. What should I do to catch someone in this act? I want something that wouldn't be obvious upon entering the room,(wires etc.) and not obvious once they get in. I was thinking maybe something to trigger a photograph to be taken from a cheap. hidden digital camera, or something to trigger a webcam to start recording (perhaps multiple?)
What I need from this, genius community (don't try to tell me you aren't, I've seen some of these projects.) Is firstly, more ideas, and secondly, possibe ways to impliment my previous ideas.
