Is there anyway to get rid of the reflection of the leds reflecting off the glass inside a window?
Maybe some kind of film I can put up?
Any help would be appreciated.

Anti-reflection coating is an expensive business, even assuming it's possible. Anything that dulls the reflection is likely to make the lighing even less effective. Your best bet is to get the LEDs to other side of the glass, if possible. If not, see whether you can get the camera close enough to the glass that the LEDs don't reflect back into its lens. Other than that, or using a viewing angle that avoids the reflections, there's not much you can do.

I have tried the different viewing angle to not catch the leds, but at night it shows them pretty much anywhere. I will try getting it closer to the glass and see if that works. Thanks for the idea.

Internal reflection is a problem with glass, you will need to get the lens sealed from the other parts of the glass with a rubber collar and get the cam right up to the glass

I had thought about making a cone from cardboard and using a large nylon washer to rest the cone against the glass. I guess this would be my best option. Will let ya'll know how it goes.
thx

If you dont need the leds you could just cover them wioth tape

An easy fix for this problem is to put a polorizer on the camera. Then the glare would be gone. Same with my SLR camera.

A walk around is to have a IR-Cutt filter then you dont see the light from the LEDs.......and you don´t need to have any LEDs anyway:)
