I want to hook up several cameras to a laptop. If I use USB webcams I can write code to view and do security stuff. BTW the software is already written and running. But the cable length is too limiting even with USB extension cables. I have access to the USB cams and the built-in laptop cam just fine. If I use video out cams CCTV what is the best way to get the video into the laptop such that it looks like a USB webcam? Or an ethernet cam that has a ethernet to USB converter. Or suggestions. Thanks!

Works fine. ftp://jjlarkin.lmi.net/CABIN.JPG You can put a powered USB hub or two into the system, too. John

I'd like to try it again.

Just don't expect fast frame rates as the four inputs are multiplexed, not a big limitation for video surveillance purposes though.

Bah!
