VIOFO CPL-400 CPL Filter – Anti-Glare, Made for the VS1

Made for the VS1, and Nothing Else. The CPL-400 cuts windscreen glare at the lens

The VS1 is a tidy, discreet camera, and the thing most likely to spoil its footage is not the sensor but the windscreen in front of it. On a bright day your dashboard reflects straight back into the lens and the camera records the reflection over the road. A CPL filter blocks that polarised light optically. Fit it, rotate it once, and the glare goes.

Who This Isn't For: This is designed exclusively for the VIOFO VS1 and will not fit anything else in the range. A119 and A129 owners need the CPL-100; A329S, A229, A139 and T130 owners need the CPL-200 at the front. If you drive mostly after dark, a CPL costs you light and may not be worth fitting.

DCG Score & Highlights

What We Love

• Purpose-made for the VS1 lens, so it seats cleanly without vignetting
• Multi-resistant coating that resists scratches, fingerprints, oil and water
• Removes the dashboard reflection that software cannot recover
• Deeper colour and stronger contrast in harsh midday sun
• Adds a sacrificial layer in front of the camera's own lens

What Could Be Better

• It costs you roughly 1.3 to 2 stops of light, so night footage will be darker with it fitted.
• VS1 only. It has no use if you later change camera.
• Needs rotating correctly on install to do its job properly.

Why a CPL Filter Matters for Daytime Plate Capture

Most disappointing daytime footage is a glare problem, not a resolution problem. Light bouncing off your dashboard and the inside of the windscreen is polarised, and once it reaches the sensor it is part of the image permanently. A polarising filter removes it before that happens, which is why fitting one often does more for plate readability than upgrading the camera.

Top Benefits

• Readable plates in bright sun: Cuts the reflected glare that washes plates out at midday.
• No dashboard mirror: Stops your own dash appearing over the road ahead.
• Better colour and contrast: Sky and road surfaces record with more depth.
• Clearer on wet roads: Reduces the reflective sheen that hides detail after rain.
• Lens protection: Takes the stone chips and cleaning marks instead of the camera.
