I have never seen a smaller digital camera with video recording capability so I assume this is the world’s smallest. It measures only 44 x 28 x 12 mm and comes in black with lots of features.
It can take pictures at up to 2048 x 1536 pixels and record videos of 1281 x 1536 at 30 frames per second with clear sound, all while attached to your keychain.
The Nano Cam seems to be a great spy gadget too because being so small it can be used as a hidden camera.
It stores AVI videos and photos on the microSD memory card and you can transfer the files on the computer via the miniUSB 2.0 interface. You can even use it as a web camera with your computer.
This miniature high-resolution DV camcorder has the following specifications: time and date stamp, 1 lux illumination, 5MP CMOS image sensor, rechargeable Li-Ion battery, 1 hour recording per charge, 3 hours charging time, external memory support for up to 8GB, compatibility with all operating systems, button for mode selection, button for power On/Off, LED light indicator, and built-in microphone.
Check all the details at Chinavasion, where you can get one for $38.
