Inside dome cameras, yes, there is a foam ring. Other cameras aren't normally affected by internal reflections like that, but can be affected by the other problems described in that document.

Thanks @klauscla@bp2008 good illustration of the issues with Domes and IR reflection
For those searching for issues, I am adding the following ( "tags" ):
dome camera has problems at night due to IR reflection ( dome security camera bad night time image )
The image included by klauscla and the pdf by bp2008 illustrate this problem well.
If I disable the IR its too dark, picture attached is with IR ON
Absolutely it could, and likely is contributing substantially to your image quality problem. It doesn't even need to be in view of the camera, just in view of the IR light.
