I finally got my hands on a DFG-1394 Firewire convertor and now have the option of using a non-dv/non-webcam camera for computer vision/realtime video etc...
So rather than a Firewire camera, it can use analogue RCA's feed into the DFG-1394. My main criteria is that is needs to work well in low light and be reasonably compact if possible.
Currently I am looking at the WATEC WAT-250D, but is it quite pricey.
Has anyone had any experience with similar cameras?
Thanks for your help!
