Why Use a CPL Filter with Your VS1?
When light bounces off dashboards or windshields, it creates unwanted glare that can obscure important details in your footage. The CPL-400 works just like polarized sunglasses—filtering out reflected light and allowing your dash cam to record clear, professional-quality videos even in bright sunlight.
How It Works
The VIOFO CPL-400 Circular Polarizing Filter is engineered to reduce unwanted reflections and glare from reflective surfaces such as windshields, dashboards, water, glass, and even painted car surfaces. By filtering out polarized light, it enhances image clarity and contrast—especially in bright daylight conditions.
Unlike standard filters, the CPL-400 allows natural light to pass through while selectively blocking harsh reflected light. This results in cleaner, more vivid footage with richer colors and sharper details, giving your dash cam a professional-quality edge.
Whether you're driving under the midday sun or through highly reflective cityscapes, the CPL-400 ensures your recordings stay crisp, clear, and free from distracting glare.
Minimize Reflections and Glare for Crystal-Clear Footage
The VIOFO CPL-400 Circular Polarizing Filter effectively reduces unwanted reflections and glare from windshields, dashboards, and road surfaces. By filtering polarized light, it dramatically enhances image clarity, contrast, and color accuracy—ensuring your dash cam captures sharper, more detailed footage in bright or reflective environments.
Boost Color Saturation and Image Depth
The VIOFO CPL-400 Polarizing Filter enhances color saturation by reducing glare and light distortion. It ensures your footage remains vibrant and rich in contrast—even in bright lighting—preventing colors from appearing washed out or overly faded.
Protect Your Lens with Confidence
Beyond enhancing image clarity and reducing glare, the VIOFO CPL-400 also serves as a protective barrier for your dash cam lens—safeguarding it from fingerprints, dust, scratches, and everyday wear. Keep your VS1 lens clean, clear, and performing at its best.

Multi-Resistant Coating for Long-Lasting Clarity
The VIOFO CPL-400 features an advanced multi-resistant coating that ensures durability and crystal-clear performance over time. Its surface is specially engineered to be:
- Scratch-Resistant – Built to withstand daily handling without compromising optical quality.
- Dust-Resistant – Repels dust particles to maintain a clean, unobstructed lens view.
- Easy to Clean – A simple wipe restores clarity—no smudges, no hassle.

A: If your driving conditions or lighting angles change, you might want to rotate the filter occasionally to maintain optimal glare reduction. A quick adjustment is all that’s needed.
Q7: Is the filter scratch-resistant or weatherproof?
A: The VIOFO CPL-400 is built with durable optical-grade materials but should be handled with care to avoid scratches. It is suitable for regular driving conditions but not fully waterproof—avoid exposing it to moisture when detached from the dash cam.
