Webcams and Security

I purchased a bundled pack of webcams over Christmas for my niece to try out Skype video. She hasn't installed it yet, so I experimented with a new freeware program called Yawcam. It has motion detection, web streaming, and FTP capabilities. I tried the motion detection feature and it works. I have one camera setup at work to see if I have weekend visitors. I need to move the camera to a different location at home, but will have to use USB to Cat5 extenders. I will try to hook up two cameras to the same computer, which will require two seperate installs of Yawcam giving the folders slightly different names. I like this program, one because it works, and two because it is free!
