GPS Based Security System
Anyone considered building their own GPS based security system?
I was wondering if you could put a usb gprs modem in the back of it, and then everytime it booted up, and a keycode was not entered, it would see where it was, and then SMS/EMAIL you its log/lat and/or postcode to a specified mobile.
Seen this: http://www.laipac.com/gsm-gprs-usb-modem.htm which made me think of it.
A simple pay as you go SMS card would be all you need, plus you can recredit it without being on the same phone with some of them.
