Looks like it should work fine. "EIA" there simply means 1-volt standard video, with negative sync - essentialy the black&white north american 525/60 standard before NTSC color was added. I suppose its conceivable that the Bt chip doesn't like true black & white video (no colorburst, 60Hz instead of 59.94Hz field rate, 15.75KHz instead of 15.734Khz line rate). But I'm sure I've heard of folks using B&W cameras with bttv cardsfor security applications. first things first though (appologies if you've already tried this): do you get a picture when connecting the camera directly to a composite video monitor or a VCR? Does the bttv card work with a color camera? -- Steve Tell [EMAIL PROTECTED] _______________________________________________ Video4linux-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/video4linux-list
