The uCorder IRDC250 wearable video recorder acts as both a camcorder and a webcam. It shoots AVI videos at 640 x 480 resolution, so it's similar to cellphone video quality. As you can see in the video above, it doesn't have a display screen. It can be set to record only audio, and has an optional LED flashlight. The model here comes with 2 GB of internal memory, but can be expanded with an SD card. It holds about 36 minutes of video per gigabyte of memory. Battery lasts up to 2 hours and blinks when low on juice. Comes with webcam stand, lanyard and clothing clip (so you can wear it like a badge.)
Recording and retrieving files is straightforward. Although there's only one recording start/stop button and no display screen, you know its recording when the light blinks.
It's marketed to be a video camera you wear, but obviously if you wear it and move around, you're going to get shaky video. (Which you can see in my video.) After 30 minutes of continuous recording, it will stop, save, and start a new file, which is meant to make the files more manageable but be a bummer if it does so in the middle of a good moment.
Also, the audio and video of the recordings were several seconds out of sync when viewed on computers without the correct QuickTime or video codec pack for Windows Media Player. That can be a headache to deal with if you're not tech savvy.
Considering that it's both a recorder and a webcam, it's a good deal for $99.99. But it only makes sense for someone who needs a webcam, but also thinks it would be neat to take it outside for some silly low-quality video from the point-of-view of a hat or chest. A student might also like this for recording lectures while sitting still.
