Just got one of these babies. Nice compact unit, takes 2 AA batteries and SD memory card. It’s designed to be a helmet cam and the video quality of somewhat similar to what you might get with a camera phone.
The video it produces is an AVI file using M-JPEG codec. Since not everyone has MJPEG codec installed on their machines it’s a bitch if you don’t know where to get a free version. If you already have a digicams with video capabilities and installed one of their software then you might be golden. But ATC2K doesn’t come with any software. Here‘s a free one that allows you to play MJPEG files.
