We've squeezed a color camera, microphone, power source, and a 4 GB Digital Video Recorder (DVR) inside a stylish silver watch. The watch is also fully functional. Camera lens is under the number 2. When you are ready to view the video or recharge the built-in lithium battery (full battery runs 2 hours), simply plug the watch into your computer's USB port. No additional software required to view video but you will need an MPEG-4 viewer such as the lastest version of Windows Media Player. Compatible with 98/ME/2000/2003/ XP/VISTA OS and Linux. Video is recorded in AVI format, no conversion needed. Just double click the file and it will play in Windows Media Player.
