That sucks! I know how you feel. I've had my wheels stolen off my driveway. This was before a camera and double wheel locks. Now i have both and why double wheel locks? Well, that'll give me enough time to go say hi to them with a g17.
Check blackvue. They have a parking mode where you'll have to hardwire it but can set how long you want it to record for after the car is turned off. I was thinking of this setup myself when i'm out and about.
