VIOFO A229 Ultra 2CH — True 4K Front + 4K Rear Dual Dash Cam

The A229 Ultra 2CH is VIOFO's first dual 4K dash cam — both the front and rear cameras record true 4K (3840×2160) simultaneously. Powered by dual Sony STARVIS 2 IMX678 sensors with HDR on both channels, the Ultra delivers flagship-grade clarity in every direction. This is the upgrade from the A229 Pro: the rear camera has been elevated from 2K to full 4K, capturing license plates, signage, and road details behind your vehicle with the same resolution as the front.

Dual IMX678 — 4K HDR on Both Channels

Both front and rear cameras use the Sony STARVIS 2 IMX678 — a large 1/1.8-inch, 8-megapixel sensor that captures approximately 2.5× more dynamic range than first-generation STARVIS in a single exposure. With simultaneous HDR on both channels, license plates remain readable in both directions regardless of headlights, sun glare, or tunnel transitions. No compromises on the rear camera — full 4K everywhere.
