Hi - I'm working on a project where I need to access two feeds from two separate webcams in jitter (on an i7 mac).

-Two ps3 eyes (this works but apparently the maccam driver - needed for this cam - slows things down to 15-20 fps and frequent hang-ups)

-Two of the same generic webcams (here I can only get one to initialize. The second comes up under the same device list heading, and when it is opened displays a black screen)

-Two different generic webcams (same result - cannot initialize the second one)

So far, cameras tested include gearhead, inland, microsoft 360 live camera (no feed in any program), and unibrain firewire (works but I need the cameras in a remote location, surveillance style, and the firewire extension cables are too short).

Has anyone tried to initialize multiple webcams with any success? At this point I'm thinking it's not an issue with the webcams I'm trying - but I am looking for something with an exposure lock that works on a mac...

Two USB webcams should work, if they crash it means they are overloading the USB bus so make sure they are going into different ports. You could try CamTwist as your driver for the second webcam if all else fails. Did you try one FireWire camera with one USB camera? That should definitely work just get an extension FireWire cable.

Thanks - Going to try Camtwist. The firewire / usb combo works but I need more than 50 ft of extension and the firewire extenders I've seen are much shorter.

Ah yes at 50ft you'll lose signal. At that length consider a compact computer, mac mini or something smaller that you could hide closer to the camera. Alternatively your looking at wireless cameras. They are quite cheap but signal is not as clean as with a webcam.
