You can do the electronics from EU 40 upwards if you don't need
a USB host. Ethernet is widely available. We run web servers and
GSM on single-chip ARM systems.

With low-end hardware, the best time/cost tradeoff will be some
sort of PC, whether ARM or i32 doesn't matter. The bigger issues
are power and comms.
If you want prevention, you'll need a tilt switch or motion
detector and a sounder - all standard security stuff. If you
want more, you'll need a GPS and GSM connection and a remote
system that causes action to be taken quickly. In some parts of
the world the standard service agreement is "armed response in
four minutes". If you just want to catch the little bleeders
later, camera and recorder systems are widely available.
When looking at existing kit, check that is was designed in
Israel, Northern Ireland or South Africa - it *will* have been
tested!
