If the reflection is coming from the dome, then you need to check and make sure there is a proper seal between the lens seal and the dome. This is what isolates the lens from any reflection. Also, make sure the dome is clean (use a microfiber cloth only!) and that there are no scratches since both dirt and scratches can reflect the IR.
The most common reason for reflection is when you have wall mounted the camera directly to a wall without using a wall mount or when it is ceiling mounted and the lens is at such an angle that one or more of the IR LEDs end up behind the metal housing. When this occurs you will get reflection from the housing itself. The solution for this is to use our wall mount that is designed specifically for this camera or to change the angle slightly so that the LED is not behind the housing.
There are other tricks you can try. Since you have spotlights, you can leave light on and set the camera to daytime only so that the IR LEDs don’t turn on. Or you can use electrical tap to cover the LEDs that are behind the metal housing and causing the reflection.

Hi Brad. I checked all of the cameras to confirm how they had been installed. Some have the foam seal around the IR ring, and some had the rubber ring around the end of the lens. None of the three had both.
All of the cameras are offset close to the gimbal limits and have IR LEDs inside of the metal housing. I taped over the hidden LEDs and built up a ring around the lens. Significant improvement.
I have ordered new mounting stands so that the lens will be pointed at a less acute angle. Can you comment on how important the foam ring around the LEDs is, as well as the rubber around the lens.
The ring around the lens prevents IR light to be filtered. The lens is not totally flush against the dome glass therefore the rubber fills up the gap between it. The Rubber around the IRs in the other hand will help the lights of the IR to be shooting straight preventing bounce back. I believe the Ring around the IRs is not as important as the gasket on the lens. Is very odd that you are missing this items due to the fact that they are coming with both from factory.
