Washer size, type?

Hello,

Before I purchased this camera I saw someone on the forum mention that they use a washer to cover the IR lights so they can get a great image while recording through a window.

Does anyone else do this? If so, which washer?

 

THANKS!!

Are you sure that wasn’t for the V2?

I’m not sure. But looking at how my Pan Cam functions it would work perfect. I was just hoping someone already has the dimensions.
