Viofo A329S 2CH dash cam

2-channel 4K front and 2K rear HDR dash cam

Powered by a quad core ARM Cortex A53 chipset and Sony STARVIS 2 sensors, the A329S records in true 4K and 2K resolution, capturing number plates and fine detail with clarity day and night.

IMX678 and IMX675 sensors: less noise, less motion blur

The front camera uses a Sony STARVIS 2 IMX678 1/1.8-inch 8MP sensor for greater clarity, lower noise in low light and less motion blur at speed. The rear camera uses a Sony STARVIS 2 IMX675 1/2.8-inch 5MP sensor with 2.5 times wider dynamic range than a STARVIS pixel of the same size, producing sharp, clear video.

2-channel HDR: clear number plates

Sony STARVIS 2 technology combined with HDR balances bright and dark areas across both channels, revealing detail and capturing accurate number plates even in fast-moving scenes.

4K 60fps recording

The front camera delivers smooth, crisp 4K at 60fps, making it easier to capture detail in fast-moving scenes. Switch to 4K 30fps for HDR recording.

2K HDR rear camera

The rear camera records in 2K with HDR, handling highlight and shadow changes to keep footage clear behind the vehicle.

Wi-Fi 6 connectivity: faster 4K streaming and downloads

Wi-Fi 6 triples transfer speeds on the 5GHz band for smoother previewing, downloading and sharing. A one-minute 4K clip reaches your phone in under 10 seconds.

Smart voice control

Spoken commands start a recording, take a photo, or toggle Wi-Fi on and off across multiple languages, keeping hands on the wheel and eyes on the road. The A329S also announces setting changes and memory card errors aloud.

Accurate GPS tracking

The built-in GPS locks onto four satellite systems — GPS, BeiDou, Galileo and GLONASS. Played back in the VIOFO app or VIOFO PC player, footage carries the vehicle's location, speed and time as a clear journey record.

Upgraded USB 3.0 port

Connect directly to a phone via USB 3.0 and transfer photos and clips at up to 55MB/s (measured on an iPhone 15 Pro Max). The same connection handles firmware updates — no card reader required.

Multiplex video: no editing needed, instant sharing

Record with any combination of camera views, from a single perspective to a multi-angle overview, with full control over how footage is presented.

Up to 4TB SSD storage

Connect a portable SSD of up to 4TB for extended recording across long trips. The A329S backs up footage from the microSD card to the SSD automatically, reducing wear on the card and keeping important clips on a larger drive. A Viofo 512GB U3 A2 V30 endurance microSD card is available separately. To enable parking mode, the Viofo HK6 hardwire kit is the matching kit for the A329S, also available with an 8-piece fuse set.
