After working happily with FW-products for many years, the recent trend of disappearing FW-ports have made me look for USB-based solutions. For hard drives the switch has been easy, and I also recently got my first USB-based sound card. The hardest part has been to figure out how to handle video cameras.
I have been using various Unibrain cameras for years, and have gotten used to the simplicity of being able to hook up multiple cameras to one computer. Last year when I tried hooking up multiple USB-based webcams to a computer (Windows, since they didn’t work on OSX at all), only one could work at a time. I was therefore pleasantly surprised when I found that Logitech’s QuickCam Vision Pro for Mac actually works well on OSX, and you can even have several of them running at the same time (see screenshot)! Now the only problem is the auto-focus and auto-contrast which tend to cause problems in video analysis (particularly when doing background subtraction).
