Meet the VIOFO A229 Ultra: VIOFO’s First Dual 4K Dash Cam, with a 210° Cabin View

If you’ve ever wished your rear camera was as sharp as your front one, this one’s for you. VIOFO’s A229 Ultra series takes the popular A229 Pro and moves resolution and cabin coverage up a level, with true 4K front and rear cameras plus a Full HD fisheye cabin camera.

It comes in two editions:

• Standard: A229 Ultra 2CH and A229 Ultra 3CH
• Waterproof: A229 Ultra W 2CH and A229 Ultra W 3CH

Key features

Rear camera: from clear to ultra-clear

Upgraded from 2K to true 4K Ultra HD, the rear camera now matches the front, thanks to its Sony STARVIS 2 IMX678 (1/1.8-inch) sensor.

• Captures fine details like number plates in low light or bad weather.
• IP67 waterproof version for vans, lorries and exterior mounting.
• Wider F1.5 aperture on the waterproof version for better night performance.

Cabin camera: from regular to full coverage

The cabin camera now has a 210° ultra-wide fisheye lens, dramatically widening coverage to take in the whole cabin and the side windows.

• Eliminates blind spots inside the vehicle.
• Sony STARVIS 2 IMX662 (1/2.8-inch) sensor plus four infrared LEDs for clear recording day and night.
• Ideal for taxi and private hire, professional driving or family road trips.

Three Sony STARVIS 2 sensors and HDR on all three channels

Expect low noise, minimal motion blur and balanced exposure in tricky light, whether it’s bright sunshine, a tunnel or a dimly lit street. HDR keeps number plates readable without washed-out highlights or deep shadows.

24/7 parking protection

Pair it with the HK4 or HK6 hardwire kit to keep monitoring with the engine off.

• Switches automatically between normal and parking recording.
• Three parking modes: Auto Event Detection, Time-lapse Recording (1 to 10fps) and Low Bitrate Recording.
• Captures critical moments like car park bumps, hit-and-runs or unexpected impacts.

Precise GPS tracking

The built-in GPS logger embeds location, speed and time data in your footage. It supports GPS, BeiDou, Galileo and GLONASS for accurate, stable positioning.

Connectivity and smart features

Fast 5GHz Wi-Fi: quicker downloads, previews and sharing.

USB-C direct transfer: easy firmware updates and fast downloads, at up to 20MB/s on an iPhone 16.

Voice control and notifications: hands-free voice commands in several languages and audible alerts for errors, so you can stay focused on the road.

Final thoughts

The A229 Ultra series is the upgrade for drivers who want maximum clarity and coverage. With dual 4K cameras, a 210° cabin view, Sony STARVIS 2 sensors and HDR on every channel, it captures uncompromising detail on the road and inside the car.
