Camera Technology

More information coming, but for now:

I want to preface any helmet cam tech with this: Unless you have a professional recording device most palm sized recorders will record around 500 TV lines of resolution. Additionally to me the highest resolution is secondary to true color, brightness, contrast and proper white balance. So do not be confused if the highest resolution camera(s) do not give the "best overall image".

Good factoids about resolution HERE.

For chip technology (like CCD vs. CMOS) check out this insightful article by DALSA, a supplier of this type of technology.

For the new generation of CMOS chips used in the Twenty20 helmet cam go HERE.
