USB2 cameras?

[Steve Holdoway]

Hi List,

Is there any easy way to get a list of cameras that are supported that
would only require a USB connection... ie that are powered over USB, and
don't need an external power supply?

Cheers,

Steve

Those are rare. Or not. Those that fit the description are usually
(also) webcams. Thus low res.

My small compact camera uses up to 2A for a short while while taking
pictures. My big DSLR too. Thus feeding such a camera over USB
directly is a problem.

What you'd really want is a camera that charges its Li cells from USB
and uses the celss for its power requirements. That is technically
possible, but whether they exist.... I doubt it. I haven't heard of
one that works this way.

Thanks for the info Roger. I do actually want it to use as a webcam, but
to generate the background image for
http://www.diamondharbour.org.nz/index.php?id=37 - so I'm after decent
size and quality image, and the ability to focus on infinity. ( I'm
seriously abusing this camera by leaving it outside under the eaves, but
it's second hand and was really cheap as the LCD was broken. It can't
really handle humidity at all ): ).

Cheers / mvg,

Steve
