Sorry to hear about your car.
Cameras kind depend on your police department. I had my garage broken into and about $6,000 worth of stuff stolen a few years ago. The dude's cousin was his getaway driver and turned him in - to me at my house. Strange to say the least, but it was all on my camera over the door. She was called at 2am to pick him up and figured he must have been stealing stuff and came back with one of my saws. Anyway I had the guys home address, phone number, name, and an eye witness account on video.
Want to guess what happened? Not a damn thing. Warrant was issued within a week. Found my bike at a pawn shop about 3 days after. It's a custom bike built off a bare frame so it's totally unique and easy to identify. (It's still there - thanks Utah lawmakers!). He was finally arrested about 2 years later. Released without bail after an arraignment hearing. Never showed up again. Our justice system is a joke. They couldn't care less about property crime.
I still have cameras to watch my dogs mostly. But I have no faith at all in my police. Even if they know exactly who did it, where the car is, you STILL might not get it back. Good insurance is about the only option. Or vigilante justice.
