I recently read about a CCD swap modification on these great
cameras, that are based around the ICX-098 mono chip.
These guys are real pioneers. Understandably, they don't get a lot
of co-operation from the manufacturers regarding reverse engineering
one of their products and so make a calculated and brave choice to
do a modification such as this.
It involves swapping it for an ICX-618ALA-E CCD which also has
5.6u pixels but is much more sensitive, both overall and in the red.
Of course, any such mod would void your warranty quick smart

I cannot verify the claims but thought it interesting enough to
pass on this link to fellow webcam modders / electronic dabblers.
