Has anyone had great success grabbing multiple wireless cameras? If so, what was your set-up? I don't need HD or fast frames per second, just something really robust that will work with a new mac pro. By wireless, I mean that the cameras won't be connected to the computer, but they will still be less than 50 feet away from the computer as the crow flies. I said firewire, because I would assume that the receiver would connect to the computer using firewire. Thanks.
