outdoor webcam
|
|
|
Anyone know of a webcam that is suitable for outdoor use? I need a
camera to take pictures through a window into a brightly lit area.
I am looking for a simple USB webcam. The ones I've tried wash out very
badly in bright daylight. I've tried shooting through dark filters, but
still, the cameras lose a lot of detail in bright light.
They are very, very good indoors and in dark rooms, but I need one for
sunlight use.
Size and price are of course a concern; I am looking for a small,
inexpensive webcam (the one I'm testing with now is golf-ball sized.)
Thanks,
--Yan |

Use an UV and IR filter. Most of the cheap webcams have lousy filters. UV
and IR have a different focus than visible light and make the picture very
unsharp.

Any suggestions for a cheap filter material? I am using a chunk of lens
cut from plastic safety sunglasses; I guess this should take care of UV.
I need more filtering to cut down on glare as well as improve
contrast; and I have no idea what inexpensive materials are optically
transprent and non-distorting and would cut out IR.
