Secure my car using mobile

[watzmann500]

Hi All ,

I'm thinking nowadays to build a circuit to help me secure my car from thives - simply i'll build a circuit to trigger a signal once my car is opened by someone else not me and this signal will go to a mobile phone hided in my car and this mobile will call my number .

did anyone thought of it before ?

waiting for your feedback

Nice idea, but it is already used. I've see it in a film, bUt I do not remember what name is. Wtahever, new ideas comes from new thought.
