Muvi by VEHO – Smaller than the average thumb!
2" x ¾" x ¾" It's the smallest spycam in the world. You can even wear it around your neck and use it as a webcam.
Muvi has a special VOX mode that lets you start/stop recording using your voice
Micro SD card slot
Despite its size the Muvi records in VGA quality (640x480). Incredible! Videos are stored on the included 2GB Micro SD card (1 hour of recording!), but for those of you who prefer real epics the Muvi can handle cards up to 8GB. (more) (sample videos)
