newbie

I'm a totally newbie at camera systems. I really wanted to buy a dropcam but couldn't bring myself to do it because I know there must be a better, cheaper alternative. I was able to get 2 vivotek TC5331 wireless cameras for free, so I wanted to give it a go and set these up. My main goal is to have them indoors at home and dropping 14 days of footage into my dropbox account. The only hardware I have at home is a cable modem and router. No idea what other equipment I need. Can somebody kindly point me in the right direction on where I can educate myself on setting up one of these systems? Thanks!
