As I see it there is 2 answers. The chip or the lens. Right now I'm testing a new (cheap, but real good) CMOS board camera. But I can't make it work with the existing 840nm IR light. When I switch lenses with another camera that works with the IR, I still get nothing. The logical answer to the question is: the chip. But how do I see it. Which specifications should I look for?

With a past in loss prevention - mainly internal theft - I have worked with CCTV. Mostly hidden off course. A B/W pinhole camera and a time lapse could normally do the trick. Sneaking in at night to switch tapes. It's amazing to see the technological development, and I'm trying to keep updated.

I bought this camera on Ali express. Great Camera. But suddenly the IR light was gone. I have tried almost everything in the OSD menu, but no IR lights. A reset didn't work either. The day/night is set to "Auto" and it changes to b/w when it darkens. But the IR lights simply don't activate. Any ideas before I shoot it? Greetings from Denmark
