I bought 2 of these a week ago for my children's teleconferencing needs. Very good camera in terms of image and sound. My only problem is that when I plugged it into my Windows 7 64-bit (on 4 different computers), it doesn't recognize it at first. After updating through Windows Update, it recognized it, but every time I turn on the computer, I have to change the USB port for it to work, especially on one computer where the position of the PC is inconvenient. I couldn't find any drivers on the Sricam website.
