USB or PCI or PCMCIA Video Capture?
I'm looking to build a small (Mini-ITX size) computer that's going to be used to capture video from 4-6 inputs. The end use is going to be mounting it in a vehicle - so I'm just looking at Mini-ITX systems that run off of 12VDC. I'm probably going to be capturing video from cheap-ish "surveillance" type cameras that just have an RCA composite output.
Due to the size of these systems, I *might* have one PCI 2.2 slot, but more likely will be limited to PCMCIA or USB2.0. I figure that USB2 has the best likelihood of working for my application.
So.... does anyone have recommendations for a moderately priced unit for video capture (just simple Composite/"RCA" input) for:
1) A USB device so I could use 4-6 of them with a 2.0 hub
2) A PCMCIA capture card that can capture 4-6 channels of video
3) A (moderately priced) PCI 2.2 card that can capture 4-6 channels.
If anyone can recommend a manufacturer, model, etc. that's known to work with (or even better, supported for) Linux, that would be great.
I've looked around on Google a lot, but I can't seem to find much that only captures simple composite video and works with Linux.
PS - I only need 640x480 resolution or so.
