The PenCorder 8GB
With 8GB of flash memory, this pen camera records about two hours of 640x480 video in the AVI format on a single charge. The camera lens is a tiny dot above the pocket clip that blends into the background. To upload the data to the computer, the top of the pen is removed to reveal a USB plug.
