Spy HD Watch DVR (4GB)Designed to look and function like an ordinary wrist watch this HD spy watch is also the first of its kind to offer 720p High Definition video. The HD spy watch records 1280x720p AVI video or 1600x1200 still pictures. The recordings are stored on the built-in 4GB of memory (can not be upgraded). This built-in memory will allow you to record approximately 1 hour of video or take over 10000 pictures. A high capacity polymer lithium battery is built-in and will power the DVR for about 2 hours. Another first for this HD spy watch is that you can use the AV out cable to review your recordings on your TV or if you prefer you may still view the recordings on your computer using your favorite video and picture software (a codec may be required for PC viewing). But the features do not stop there-the HD spy watch is also waterproof up to 98 feet and can be used as a webcam. As an additional option we have included a genuine leather band-its like getting 2 watches for the price of one. The HD spy watch comes with a USB cable and AV out cable and 1 metal band and 1 genuine leather band and wall adapter for charging and microphone cover(for under water use)and user manual and CD. The watch face measures one and seven-eight inches by one and five-eight inches.
