I'm sorry to hear you got hit again, that really sucks.
Considering the money we pour in to our bikes, adding a camera system to the area isn't that bad. Among others, Walmart has this option: http://www.walmart.com/ip/Linksys-Wireless-N-Internet-Home-Surveillance-Camera/13909290?findingMethod=rr.
I got the one I'm using
at Costco, for about the same or a little less price. From what I'm looking at from the Walmart website though, this one looks pretty good as a starting package: http://www.walmart.com/ip/SVAT-TWR301-GX012-Digital-Wireless-DVR-Security-System-with-receiver-SD-Card-Recording-and-Long-Range-Night-Vision-Cameras/15052132?findingMethod=rr.
The DVR included is a nice thing, the Uniden I've got is plugged into our house server PC to display and to record video.
