Has anyone thought about or tried to implement a car security system with carpc? A lot of the hardware seems to be there already, and so much is possible with gpio and simple script. Could maybe a backup power supply be used to run the system when the car is off? Maybe a small webcam inside, a GPRS module that can email GPS location and interior photo if car is stolen? Any other ideas? Just trying to brainstorm :)

great idea!

It will be nice to have :
- a system, when the rpi is starting it will ask a passcode and if there will be not the passcode, the engine stop
- a system to record (with gps) the way and archive it when the rpi shutting down
- a gsm/gprs module to send info when the car is moving without the passcode

I'm not too sure about the coding side as I'm a complete newbie at Linux but a 5v relay cut into the fuel pump supply, controlled by a gpio script should be easy enough to do. Eg if the pass code is incorrect it sends the pin low, which cuts power to the pump. A possible problem is DTC that could be stored on newer cars, if the fuel pressure is monitored by OBD.

any other ideas? This is something I think I will try to do :)

I would not consider connecting my raspberry to such important systems like fuel-pump. Imagine, your raspberry crashes, and the relais cuts power - the engine would immediately be without fuel, and that could end up in an accident or a significantly damaged engine...

I agree, I was not recommending it, merely bouncing out ideas. Also, a fuel pump malfunction of any kind will not damage an engine, I say this in full confidence as I'm a qualified mechanic!
Again, this is just to get ideas from other users imagination :)

I think the fuel pump Idea is a good one, just make sure the relay is a default "on" one so if the rasberry crashes or runs out of battery when the car is sitting for a long time, the car will have fuel.
I also second sherthisisit on the fuel pump not damaging the engine (although I'm just a highschooler in autoshop)

Edit: just noticed how old the thread is, a bit late on this
