This is a tear-down of a small digital video recorder from China that takes video with audio, and still images. See transcript below.

http://www.chucklohr.com/808 has the full review and has sample video, audio and images.

As of April 2012 there are at least 16 versions of this camera. This tear-down is the #1 version that has the least video quality and fails often.

This camera failed because it has a counterfeit flash memory chip. See


I was able to revive this camera using these instructions:


Once you figure out how it works, and understand it's limitations, it works amazingly well. It is useful as a "webcam" quality video camera, a good quality audio recorder, a toy quality photo camera, or an 8GB flash drive.
It is light enough to be build it into an RC plane, car, boat, or model rocket. See this video http://www.youtube.com/watch?v=Uo2p_7...

This is a tear down of the 808 car keys micro camera. This is video camera and a still image camera.

Here's an American nickel for size comparison. And the weight of this unit is 15g or the equivalent of 3 American nickels.

The features on this unit are the on off switch, the mode switch that allows you to select whether you want to take a photo or video, 2 false keys, a LED indicator, a place to attach your keys, USB mini connector, a hole for the reset switch, the camera lens and the microphone.

This is a clamshell design. I've already taken the screws out.

This is the lithium-ion battery, it has its own protection circuit on the top, a very tiny circuit board on top of battery. It's a protection circuit. And on this printed circuit board there is a reset switch, there is the flash NAND chip, there is a multimedia processor, there is a mini USB connector, there is a microphone and there is the camera. There is a 12 MHz crystal.

And I have taken the screws off, there are 3 screws that hold this printed circuit board in here. Here is the inside of the other side of the clamshell.

And on this side of the circuit board we have 8 MB of RAM, an on off switch, this is the photo video switch, that is the LED and this is the camera, the flat cable connected to the camera, and the connector for the camera.

The flat cable fits into this by compression. If I move this compression bar ... there is the camera. It has a 24 pin gold connector on it here, and flat cable. There is no manufacturing identification on the camera. It does not disassemble. It says JC - 70 30 - CQ or GQ on the flat cable.

Assembling this back together, set this compression bar.

The total weight of this camera, of this assembly right here is 10 g, which is the equivalent of 2 American nickels.
