WARNING WRONG PATH
Posted: Fri Nov 25, 2005 6:13 am
That was the gist of two recent emails regarding using firewire for linux surveillance: Warning, wrong path!
Seems there are definite issues with cable length and repeaters vs standard CCTV cams or even USB2.
Also, apparently there is not yet (Nov 2005) a frame-capture driver that rips from /dev/video1394/0 devices to regular jpegs. We looked at CORIANDER, but that seems to be mainly a GUI.
Also, the iSight (vs even a logitech quick cam pro 4000 -- google for isight versus logitech) doesn't fare well in low lighting, precisely because it "thinks too much" with auto-everything.
Sooo...unless we hear or find some good news in the next few days, we will probably be changing to a safer route, which seems to include cctv cams and ituner spectra/8 or linuxmedialabs cards.
Now for a midnight turkey sandwich!
