VIOFO CPL-300 Filter for A229 Plus/A229 Pro/A139/A139 Pro Rear Camera | Anti-Glare Circular Polarizing Lens, Reduce Reflections and Glare, Enhance Color Saturation, Easy Installation and Removal

Cleans up the reflective glare in the video making details easier to see.

This worked for my generic Apple CarPlay/Android Auto aftermarket head unit front dashcam (this camera is integrated on the head unit). After applying the filter the colors look way better and not washed out. The clarity has also improved - I could legibly read some license plates after reviewing SD card video footage. The visuals look about 25% clearer with the filter. Easy to apply and does the job.

First one was cracked but I was sent a replacement. They are pretty fragile so have to be careful when installing. Didn't help that I did not buy it till after the rear camera was installed. Unlike the front you have to unstick it so I had to rotate camera and install. Save your self some trouble and install filter before mounting camera.

Great accesory for the rear camera of my Viofo A229 Plus.

Worst product ever! The clear protector plastic doesn't come off easily or not at all. The sticky back to adhere to the lens is not strong enough to keep the lens in place. Minus 1 star.

the lens isn't meant for my camera but none the less once attached it's still a cpl filter the lens does help slightly but only slightly does not make a major improvement in the video playback unfortunately

Great product and quality. Would definitely buy again.

Worked well and helped relieve Windshield glare.
