(SOLVED)Live image all blown out with light,,but working....
4 days searching and changing things with no luck....I will break down and ask....I installed and got Zoneminder up and running and have a live picture....Trouble is,,i cannot seem to keep the image from being blown out with light no matter what i do....I have changed everything i could in the options and screen settings....Brightness,,contrast,,and everything else....Beginning to think my new low lux cctv camera or fisheye lens has a flaw or simply will not focus(store i bought it from matched the 2 and said it would work perfectly)....I installed xawtv and it shows the same picture as Zoneminder(all blown out with light)....It should not be this way in the image....Camera and lens are new....

Hi,
The screenshot is broken. However, there isprobably nothing you can do about it, cameras are very sensitive to sun light, and they react to light by opening\closing the iris (i believe thats the correct term) and thats how they control how much light gets into the camera. However, with most cheap cameras, the iris is not electronic and therefore fixed, because it cannot move. The DSP (digital signal processor) then manipulates the light using software, not as good as electronic iris, but it works, similar to photoshop, if you try to remove lots of sunlight, the picture might be too dark, etc. thats why its trying to find a compromise, after all, light is needed and there should be no problem with light, as long as its evenly distributed, but in your case, its probably not.
You can try moving the sun protector above the camera a bit towards the lens\glass, to try decreasing the amount of light that goes into the camera.
You can also try pointing the camera a bit lower, less light from the sun should get inside and if its not possible to point it lower, you can try mounting it higher and then you should be able to point it lower to your desired point.
