i was looking online at the circuit city and best buy sites and saw these "SD memory card" camcorders. anyone know what these are? and would they work for setting up a helmet cam with helmetcam.com setup?

Um, cameras that record onto SD memory instead of video tape. Obviously this makes them very compact.

what is SD memory? how does it work?

The SD recorders typically record to MPEG-4, which is a compression method but one of the least destructive, not MiniDV, which is what most amateur camcorders record to now. Unfortunately my experiences with MPEG-4 and snow scenes have been disastrous... even at really low compression entire areas of snow are converted to plain white.

The cards they record onto look like this :

(About 4/5" * 4/5" * 1/20")
You can commonly get them in sizes from 16MB - 1GB, though if you dig about (Camera shops are a good place) you can get them far bigger (Last one I saw was 1.5TB, but that wasn't on sale).

Basically : results often not as a good as a real camcorder (though this will obviously change from camera to camera), but they are often smaller and cheaper (might make a nice helmet cam if you don't want to risk your real camera)

Yeah, SD stands for "secure digital." Basically it's digital camera memory. Here's a description from http://www.bhphotovideo.com/bnh/cont...emcard.jsp#tmc

The Secure Digital (SD) Card is similar to the MultiMedia Card in appearance and is cross-compatible with the MultiMedia card. It is a highly secure stamp-sized flash memory card with cryptographic security for copyrighted data based on proven security concepts from DVD audio. Jointly developed by Matsushita Electronic (best known for its Panasonic brand name products), Sandisk and Toshiba, the SD Card maintains a high transfer rate for fast copy/download. It also exhibits low power consumption to maximize battery life in small portable devices, Making it a good choice for digital cameras and other portable digital devices such as MPEG Players and cell phones. The Secure Digital Card is distinguishable from the MultiMedia Card by the user selectable mechanical write protect switch on the exterior card casing.

I just switched from using my sony trv-900 on my helment cam to the Sony hc-40. The hc-30 will work also. Camcorder has to be able to accept input in. Lots of the cheaper camcorders will not accept an input into them. The HC-30,40 ones are small. 2 1/2, 3 1/2, 3 1/2 I think.
These are Micro DV.
