I used Dropbox (http://www.dropbox.com/) to provide online storage for iSpy (http://www.ispyconnect.com/) to capture pictures and video when motion is detected. iSpy saves the pictures and video to my online web storage so if the computer that is taking the video is stolen, I still have the evidence offsite. That and I can monitor security from outside the house.This shouldn't cost any money as long as you have a webcam and a persistent internet connection. It's great for dorm rooms or home office security.
