In the era of HD, you thought good old DV was dead? Wrong! Because manufacturers can now make these low resolution cameras smaller than ever.

The Muvi Micro DV Cam measures just 2x0.8x0.4 inches but still manages to record 640x480 video at 30fps for 2-3 hours per charge. All of the footage is saved to your own MicroSD card and can be transferred while the camera recharges over USB.

Beyond basic recording, the camera can also be cued to record at a threshold of 65 decibels of noise. And with the disclosure of that spec, several thousand Giz readers immediately Googled "decibels lady changing." $129. [i want one of those via geekalerts]
