Infrared Image with white dot?

I fount there were many white dots in infrared stream. Here is one of my pictures. Can someone tell me What it is And how to eliminate them?

Are you referring to the white dot in the center of the image or the tiny dots all over the image?

Have you found a solution to this problem? I’m using the Astra Stereo S U3 and am seeing a strange dot pattern in my IR stream as well. I know I’m just missing a setting because when I start the stream from another 3rd party library it works great.

Right now it looks like this:

Any help would be greatly appreciated.
