Security

Hi
I am trying to beef up the security for my bike.
It is kept overnight in the gated garage under my apartment block and locked to a concrete block.
I want to do 2 things:
Track it if its nicked
Get notified if someone tries to nick it.

I have found a tracker - http://www.maplin.co.uk/search.aspx?MenuNo=11870&MenuName=Tracking+Devices&FromMenu=y&doy=14m7
which I like because it doesn’t tie me in to a tracking company although not sure if that is a really an issue.
but I want some sort of device that when it gets triggered will notify a remote receiver so I can catch the buggers. eg the device would have a discrete wire that would be be attached to the wheel and when the wheel is moved the wire triggers the transmitter to go off. It doesn’t have to be specifically for bikes but wondered if anyone used or knew of something that might be suitable.

Cheers for your help.
