I need a sub $300 wireless surveilance system

Any recommendations?  I'm soon moving into a really nice apartment which happens to be on the edge of a not so nice neighborhood.  I need a wireless surveilance system that either records it's own video, or one that can be linked to a dedicated computer in ad-hoc mode to record the video that way.  Night vision would be a huge plus.  Zoom is not important as I will be mounting this very close to where our cars are parked.


These, and connect them to some crappy computer you have laying around to use as a DVR.

These look awesome but I dont think I can use them.  I guess I forgot to mention that they will need to be able to be used outdoors.  I live in Wisconsin so cold/snow/rain can't be an issue.
