I've been doing a few dashcam reviews lately and I noticed that all of the rear cameras look pretty terrible when the back dash reflects in the window. Then, I noticed a polarizer for the rear camera on Viofo's webpage.

A few days later, they arrived in the mail.
There is a thin adhesive already applied to the polarizer. Just peel the protective films from the lens and the adhesive and stick it on. The polarizer itself is well made and a bit thicker than I expected. It is also pretty rigid. You can use it on other rear cameras, but wherever you mount it needs to be completely flat.
I don't have any "before" images to make a direct comparison, but there is substantial reduction in the glare off the back dash, especially the reflection produced by the rear speaker grilles. I'm also seeing more saturated colors which adds a little eye appeal. Previously, I had reduced the EV setting for the rear camera to -0.3. It's time to raise it back to 0.0 or maybe +0.3 to compensate for a bit of increased contrast / lost brightness, but overall, this was a very worthwhile addition!
In these first three images, the sun is directly in the frame, so this is a situation of maximum potential for reflections in the rear window. There is a little bit of flare at the bottom of the image, but that's not an issue because it overlaps with the interior of the car.
