Re: Pinhole B&W camera probs

["Bob Noble" <bnoble@xxxxxxxxx>]

I don't see anything in the specs on weather the ir will work or not.
The camera is very small so may not be able to move an ir filter. My
understanding is the cams that work with ir, work in black and white and
have to move the ir filter out of the way. They work in zero lux, because
you are now working with the ir lights. The lux spec given for the camera is
for light, not ir. IR works in zero lux. It doesn't need light. Get it? :O)

Just for grins, have you gone into the camera's settings and tried turning
up the brightness setting?
The ir filter may let enough through it to see if you try turning this up.
As I remember, this is something I had to do with one that had built in ir
illuminators, so you should check this out if you haven't.
Are you feeding this to a computer?
