So Today My Car Almost Got Stolen

[JohnnyRockets]

I bike to work and today when I got home, I see the below image.

!@#$% ^&*(!!!!!!!!!!!!!

All the pieces are on the ground below my door. Luckily, I think they botched it and couldn't get in. But I'm sure the !@#$ers will be back.

The parking garage is below my apartment. The WiFi signal reaches and is quite strong. Is there any sort of camera I can use that will:

A) Take pictures if motion is detected in the parking garage.
B) Upload pictures automatically to the internet (Dropbox etc).
C) Operate off of non-car battery power while the car is off.

Does something like this exist?
