It appears to be a generic/rebranded version of a DigiGR8 100k keychain camera/webcam. It also appears on ebay at a surprising prices considering the underwhelming performance of the camera.
A few years back I got a visually similar unit out of a claw machine, I think it was branded "Bell & Howl" (yes, spelled like that). It was 'toy' grade, and I found it to be of no real use, even when I got it to work.
The reviews at Amazon tell a similar story. Although it seems to have been put to use as a webcam for use with Skype.
I also remember the 'manual' was a card double-folded to match the size of the camera. It had very basic 'engrish' instructions on plugging the battery in and the USB-mini cord that came with it, nothing about drivers or anything. There was a mini 'business card form-factor' cd that came in the blister pack that had a software package and drivers. I could not find a source for those files, and that CD is long since gone.
A google search for DIGIGR8 CD-10B4 came up with a number of distributor websites, listing it as "Generic" so its likely produced with the branding the company ordering the units wants. If that is the case, the original manufacturer is likely not in business anymore. I did not see the Bluetech name in the search results I surveyed.
Highlights from the Amazon page give the unit these stats:
- 100K pixel CMOS Sensor
- 16 MB internal memory
- 352 x 288 pixels image resolution(CIF)
- 176 x 144 pixels image resolution (QCIF)
I hope this helps.
