    I bought a IR illuminator for use with a color/B&W pinhole camera, It
    doesn't pick up much better than in total darkness. Are their different IR
    illuninator freqs? The IR is supposed to work with any camera.

    Depending on the camera and IR source, You need quite a bit of I/R power to
    reach beyond 60ft. Pin Hole cameras are not very effecting beuond 60 ft. If
    what you are doing is beyond this range you need to upgrade your hardware.

    The illuminator I have for this is rated for 120' The lux on this camera is
    ..1 so it's probably unsuitable for this

    That lux rating is for use with light. With IR illumination, it doesn't come
    into effect.

    The ir will only work in black and white mode, as in color, there is an ir
    filter in place.
    There may also be a setting in the camera software that puts the camera in
    low light mode, which may remove the ir filter that is used in color mode.
    You may also need to go in the camera's setting and adjust the brightness
    control.

    Dig deeper.

    low light if it helps figure this out. I sure can't at the moment

    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?
