This is a good idea. I've had lots of ideas about alarms and how they could be better after that break in. I have a fence electrifier that I'd love to get set up but I don't want to fry anything inside the van. Another idea is something that sets off something _extremely_ loud inside, like a firework. Sadly the off the shelf part does the job well enough that I will probably never invest much time tinkering. I've asked the vendor about public APIs but they are not interested. If someone builds a simple car alarm kit with cell connectivity I will gleefully rip out the old system.
