Hi Tracy,
An option that gets "good marks" in the forums is PC Companion. It might just do everything you need. The basic version is available as a free download, but I think you'll have to donate to get all the camera support.

http://www.blueirissoftware.com/It supports the X10 VA12A and VA11A, as well as many I.P. cameras. It does
not, however, allow you to control your X10 cameras, so you'd need some other way to do that. They, too, offer a 15 day free trial, so you can try before you buy.
Good luck!
