That's clear, but, another problem in dome cameras, is reflection from dusty dome outside surface. And, when we clean this surface, after some time scratches appears on surface, and reflection effect becomes permanent....

Another, appearing at any camera with integrated IR (even, when separated glasses are used for camera and IR) issue:
Also, big problem appears at high snow.
Separate IR lighting, placed at about 0.5m below camera - more times better solution, if you want good night time image.

That rubber ring on the Axis P3225 is a bit of an annoyance, because it's so stiff, if you don't put the dome on exactly straight, it can push the camera's aim out of place.
One other thing I've noticed with some cameras is, over time, the gasket itself can leave a permanent mark on the bubble, which can then affect the image if you ever have to re-align/re-aim the camera.

I have switched to turret and bullet after contending with all the issues with domes that you guys have mentioned.

I've also used turret a lot to deal with this.

Even with this ring though, you can still get some IR reflection from the light going sideways thru the glass and then bouncing off of dust or moisture on the surface.
Older bullet cameras used to have a similar ring to these domes, but now are usually thru-the-glass rings for this reason:

We had at a period a big problem of IR reflection with dividers. The supplier has solved the problem by changing the plastic cover by another one which had been treated to herden the plastic (I don't know exactly how...). It's the supplier of the plastic dome that has done this special treatment.
And the result was good.
To avoid this problem, I prefer to use "ball cameras, like this model:

Note to all, based on findings from this test and reader comments, we plan to do some testing of dust/dirt/scratch impact on IR image quality to show those specific effects.
I believe we also have a test on IR cameras in snow which I can't honestly remember the title of... but I have images from it, and yes, integrated IR when snowing obscures a lot of the FOV:
