VIOFO CPL-300 Rear Anti-Glare Polarising Filter

The VIOFO CPL-300 Rear Anti-Glare Polarising Lens Filter is designed for compatible VIOFO rear cameras. It helps reduce unwanted glare and reflections from glass, road surfaces, vehicle interiors and bright sunlight, allowing your rear camera footage to appear clearer and more balanced.

A CPL filter is especially useful in bright daytime driving conditions, where reflections from the rear window, road surface or vehicle cabin can reduce image clarity. By reducing glare, the CPL-300 can help improve contrast, colour saturation and overall rear camera image quality.

• Reduces Glare: Helps reduce reflections from glass, road surfaces, metals and shiny surfaces.
• Improves Rear Camera Clarity: Helps produce clearer and more balanced rear footage.
• Enhances Contrast: Helps reduce washed-out footage caused by strong sunlight or reflections.
• Better Colour Saturation: Helps colours appear more natural and vivid during recording.
• Lens Protection: Adds a protective layer against fingerprints, dust and minor scratches.
• Easy Installation: Designed to fit compatible VIOFO rear camera lenses.

Rear dash cam footage can be affected by reflections from the rear window, road surface, bright sky, surrounding vehicles and shiny surfaces. The CPL-300 uses a circular polarising filter design to help reduce these reflections and improve rear camera image quality.

This can be helpful where rear window reflections, bright sunlight or vehicle interior reflections are visible in recorded footage.

Strong sunlight and reflections can make rear dash cam footage appear washed out or overly reflective. The CPL-300 helps maintain better image contrast and colour saturation, making rear footage easier to review when checking surrounding vehicles, road conditions and incidents behind the vehicle.

In addition to improving image quality, the CPL-300 also helps protect the rear camera lens from fingerprints, dust, dirt and minor scratches during everyday use and cleaning.

The CPL-300 is designed for selected VIOFO rear camera models. Please check your dash cam model and rear camera type before purchase.

Compatibility note: The CPL-300 is not a universal CPL filter for all VIOFO cameras. Please confirm your rear camera model before ordering. For front cameras or newer waterproof rear cameras, a different CPL filter may be required.

To install the CPL-300, align the filter with the compatible rear camera lens and attach it carefully. After installation, check the live view or recorded footage to confirm that the filter is correctly aligned and glare reduction is working as expected.

Important: CPL filter performance depends on sunlight direction, rear camera angle, rear glass angle and interior reflection. Some adjustment may be required for best results.

Clean the CPL-300 using a soft microfiber cloth. Avoid abrasive cloths, paper towels or harsh chemical cleaners, as these may damage the filter surface.
