Overview

The Neewer 10104838 Dashcam CPL Filter is purpose-built for VIOFO front-facing dashcam cameras, including the A229, A139, A139 Pro, T130, and WM1 models. Its primary function is to cut reflections from the windshield and other non-metallic surfaces that commonly wash out dashcam footage. By filtering polarized light, it reduces the bright dashboard reflection that overlays many recordings, making license plates, road signs, and lane markings noticeably easier to read in playback.

The filter uses multi-coated HD optical glass to minimize aberrations and light scattering, paired with a water-repellent, scratch-resistant surface that holds up to daily use. The aluminum alloy frame keeps the overall weight at just 0.63 ounces, so it does not stress the dashcam mount or shift the camera angle. Beyond glare reduction, the polarizing effect enhances color saturation, producing more vivid sky and landscape tones in driving footage. For VIOFO dashcam owners who frequently drive in bright or variable lighting, this CPL filter is a practical upgrade that improves footage quality without any change to camera settings.

Key Features

【Fully Compatible with VIOFO A229/A139/A139Pro/T130/WM1 Front Camera】 This CPL filter is customized to be compatible with VIOFO A229 A139 A139Pro T130 WM1 dashcam front cameras to ensure perfect compatibility. It focuses on front camera adaptation, enabling users to install it easily

【Reduce Reflections from Non Metallic Surfaces】 The circular polarizing filter minimizes reflections from car windows, water, and smooth surfaces, similar to a polarized filter. It reduces unwanted light interference and helps address glare issues from a dash cam, making road signs, license plates, and other details clearer for more reliable recordings in various lighting conditions

【Enhance Color Saturation in Video Recording】 By increasing the color saturation of images, circular polarising filters make the colors in the scene more vibrant and natural. This feature is particularly useful for capturing changing weather conditions or landscapes, adding depth and detail to the footage

【Multi Coated Optical Glass】 The multi layer coating technology effectively reduces optical aberrations and prevents light scattering, resulting in clearer images. The high quality optical glass also enhances the filter's durability, ensuring stable performance and consistent image quality over time

【Robust and Lightweight Frame】 The circular polariser filter's frame is made of high quality aluminum alloy, a material that is not only strong and long lasting but also lightweight and easy to install. The aluminum alloy frame design ensures that the filter does not add an extra weight burden during use while also providing long lasting stability
