【Compatible Dashcam Models】 The 40mm circular polarizer is exclusively compatible with Vantrue E1 Pro, E1, E2, E3, E1 Lite, S1 Pro, N4 Pro, N5, and N2X dash cams. It enhances image quality, providing clearer and more detailed footage for driving records, both day and night, ensuring an improved dashcam experience 【Reduce Reflections & Enhance Contrast】 Crafted from glass with a premium polarizing layer, this polarizing filter effectively eliminates harsh glare and windshield reflections, enhances contrast, and retains color accuracy. It helps capture sharp, vibrant footage in bright sunlight, rainy conditions, or nighttime driving, ensuring critical details like license plates and road signs remain visible 【Multi Coated & Ultra Slim】 This anti glare CPL filter features multiple resistant coatings, making it fingerprint resistant, scratch resistant, waterproof, and oil resistant. It not only enhances your dashcam's imaging performance but also provides extra protection against dust and other potential damage. Featuring an ultra slim design, it seamlessly integrates with your device without obstructing the camera's field of view, delivering improved footage with minimal vignetting and no distortion 【Adjustable CPL for Dashcam】 This Polarizer Filter allows precise control over polarized light reduction through rotation, giving you the flexibility to fine tune the filter based on changing driving conditions. Whether you're dealing with direct sunlight, reflections from wet roads, or glare from windows, the adjustable design helps reduce unwanted reflections, enhancing overall image quality 【Note】 Under strong direct light (such as sunlight or neon lights) or when shooting from certain angles while driving, temporary rainbow flare or streaks may appear on the footage. This is an optical diffraction phenomenon caused by the coating of the CPL filter, not a malfunction. It is common in high light transmittance lenses and does not affect the core functions or image clarity of the dashcam
