3 reviewsWhy You Need a CPL Filter for Your Dash Cam
Under the bright Saudi sun, severe dashboard reflections can ruin your dash cam footage. A CPL (Circular Polarizing Lens) filter acts like polarized sunglasses for your camera, drastically improving video clarity:
✅ Eliminates Dashboard Glare:
Instantly removes the annoying reflection of your car's dashboard or AC vents from the inside of the windshield during bright, sunny days.
✅ Enhances License Plate Capture:
By reducing harsh environmental glare and improving color saturation, a CPL filter ensures fast-moving license plates are captured with crisp, readable precision.
✅ Safe for Night Vision:
Our high-grade polarizing lenses are precision-tuned to reduce headlight glare at night without heavily darkening the footage or compromising the Sony STARVIS sensor's night vision capabilities.
✅ Quick Snap-On Installation:
Designed to perfectly fit over your camera lens. Most filters attach via a simple magnetic or clip-on mechanism, requiring zero tools to install.

CPL Filters FAQ
What is a CPL filter for a dash cam?
A Circular Polarizing Lens (CPL) filter attaches over your dash cam's main lens. It functions just like polarized sunglasses for your camera, effectively cutting through glare and blocking polarized light.
Do I really need a CPL filter in Saudi Arabia?
Yes. With intense Saudi sunlight, your dashboard often reflects heavily onto the windshield, obscuring the camera's view. A CPL filter eliminates this dashboard reflection, ensuring clear license plates.
Will a CPL filter make night video too dark?
While they reduce a bit of light, premium dash cams with Sony STARVIS sensors automatically adjust their exposure to compensate. Your night footage will remain clear, bright, and highly detailed.
How do I install the CPL filter?
Installation is simple. Most easily clip on or slide over the front lens. Once attached, just look at the camera screen and gently rotate the filter's dial until the dashboard reflections disappear.
Are CPL filters compatible with all dash cams?
No. CPL filters are designed to fit the exact lens shape of specific models. You must buy the exact CPL filter made for your camera series (e.g., a VIOFO A229 filter for the A229 camera).
Does the CPL filter protect my dash cam lens?
Yes! In addition to improving video quality, the CPL filter acts as a physical glass shield, protecting your camera's primary built-in lens from dust, scratches, and fingerprints.
Can I use a CPL filter on the rear camera too?
Yes, if your specific rear camera model supports it. While glare is worse on the front, adding a CPL filter to the rear camera helps reduce glare from window heater lines and trailing headlights.
How should I clean my CPL filter?
Clean it gently using a dry, clean microfiber cloth, just like you would clean eyeglasses. Avoid using harsh chemical cleaners or rough paper towels to prevent scratching the polarized coating.
