Brigness problem

Ok guys, I have this camera that I installed today at a client's site.

it sits in the backroom, it's a check cashing place, so it's behind the wall.

I have a Manual Iris 3.5-8mm lens, and the camera is a photronics 327na.

The problem is that if I face the camera directly, I look as a black, you can't make my clothe color, or my face, it's completely black, but my surroundings are clear, only If I open the iris high enough, then you can see me clearly, but the rest of the area is whiteout.

Any suggestions?

If the camera has a back-light compensation (BLC) switch, set it to ON.

#1 - Try a Different Lens.
#2 - Adjust the Iris Pot on the Lens
#3 - Make Sure you are looking at this direct at the Camera, not through a DVR or any distance.
#4 - BLC on = Brighter - generally it should be set to OFF, but if you are having issues, try it ON.
#5 - WHAT OTHER settings does the camera have? Can you send a link or image of the settings on the camera? There are other settings as well, that can cause it to be dark like that.

I don't know the camera, but it sounds like the Electronic Iris function is switched off (assuming it has one :wink: )

It's a manual iris.

Manual Iris lens .... o.k.

Electronic Iris (EI) or Automatic Electronic Shutter (AES) switched on in the camera????

Herminshs, what type of camera is it? do you have a link or pictures?.
