Thanks for the help. Hopefully these don't accumulate a lot of crap on them. I can imagine a dome camera.
I still think and auxiliary IR would help you a lot, especially further from the camera.
Here's a capture from a 5442T, 6mm. The IR in the camera is off but there is IR from another camera, mounted basically mid-frame, and an auxiliary illuminator out even further. I get sharp captures of deer and fox with this setup, not to mention people should they wander in at night.

These work really well and a lot smaller footprint than some others.
Review- New Design Tendelux 10 Watt IR illuminator.
So I purchased one of the new redesigned Tendelux Ir Illuminators to give it a try. You can see it here I have two other older Tendelux IR illuminators that are still running strong after almost 3 yrs in use. One is an 8 watt model, and the other is a 4 watt model. And they've done a fine job...ipcamtalk.com
I run 162 or 18/2 when I run the CAT cables to provide power for auxiliary IR. It takes a load off the switches that way.
I'm using these. The big one lights up the whole back yard, about 200 x 220, for all the cameras back there. I do have IR on for one camera to fill the shadows created by the big IR flood though. I;ve seen good reports about the Tedelux wittaj mentioned as well. Mine have been up for a few years with no problems.

Can you not aim your camera further to the right to remove most of the siding from view?too much IR glare off the siding
