B&W picture full of distortion?

[deserteaglexxx 0]

I have an Avigilon pro series 4.2 mp camera in B&W with .001 lux when it gets close to dark the picture gets very snowy you can see things but the interference sucks for a high end camera. Any ideas what it could be?

Snowy pictures in dark scenes are the AGC kicking in. If the camera has an AGC switch you could try turning it off but most likely the resulting picture will be too dark.

 

You will either have to add light (visible or IR will do), or get a camera that has better low light capabilities. By the way, I don't know about Avigilon but my understanding is that megapixel cameras aren't very good in low light situations.

I agree. I haven't used Avigilon but try playing around with the video settings.

 

Do you find the FPS drops during the snowy periods as well?
