Pinhole B&W camera probs

Feb 28, 2007 4 Replies

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. Dave Remove the 2 to respond off list


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 Dave Remove the 2 to respond direct

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.

It's made by plex here's the specs on it. It switches from color to b&w in low light if it helps figure this out. I sure can't at the moment
