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!

I have a USB cam 70 feet from a mini-ITX PC; one 10 foot passive cable
and two 30 foot active extenders, one of them outdoors. Works fine.

You can put a powered USB hub or two into the system, too.

There are video to USB converters - google

You can usually run the video cable long distances with no problems.

Yeah, I use a mixture of USB and vid-to-USB connections, I've
been through a few of them during testing and found KWorld was
the least hassle:

(USB 2860 device) works well in Windows XP and Ubuntu.

I tried this (only one time) - buying a repeater cable but it failed
miserably for me, purchased from eBay - can you tell me what
make your extenders are please? I'd like to try it again.

A dirt cheap four channel USB video capture card might do.

capture-surveillance-dongle-11127>
I have one identical to that one, works like a charm and is Linux
supported. Just don't expect fast frame rates as the four inputs are
multiplexed, not a big limitation for video surveillance purposes though.

Yeah, but 13Mb/s should be fast enough for std resolution video.
there may be a faster version out there somewhere.

Just on a side note, I was reading about USB 3.0 and it turns
out the max (normal) length is no longer 5m, but 3. Bah!
