VIOFO A329S 2CH (4K 60fps+2K HDR) Dual Dash Cam

Overview

The VIOFO A329S 2CH is the 2025 flagship dual-channel dash cam that sets a new industry benchmark as the first consumer dash cam capable of true 4K (3840x2160) recording at 60 frames per second on the front channel. Built around a Quad Core ARM Cortex A53 processor and dual Sony STARVIS 2 sensors (front IMX678 8MP, rear IMX675 5MP), it delivers exceptional clarity with HDR on both channels, proprietary Low Power Impact Detection parking mode (<40mA standby), and Wi-Fi 6 for ultra-fast smartphone transfers. The modular architecture supports expansion to 3CH with cabin, telephoto, or waterproof cameras, external SSD storage up to 4TB, and features voice control, built-in GPS/GLONASS, and a supercapacitor power system for reliable operation in extreme temperatures.

Key Highlights
  • Industry-first consumer dash cam with true 4K (3840x2160) recording at 60fps on the front channel — ultra-smooth video with half the motion blur of standard 30fps dash cams, powered by a Quad Core ARM Cortex A53 processor and Sony STARVIS 2 IMX678 sensor
  • Dual Sony STARVIS 2 sensors — front IMX678 (1/1.8", 8MP) for 4K 60fps and rear IMX675 (1/2.8", 5MP) for 2K HDR — delivering approximately 2.5× wider dynamic range than first-generation STARVIS for exceptional license plate capture day and night
  • Wi-Fi 6 (5GHz 802.11ax) with transfer speeds up to 30 MB/s — roughly 4× faster than the A229 series — enabling a 1-minute 4K clip download in under 10 seconds via the VIOFO App
  • Breakthrough Low Power Impact Detection parking mode draws under 40mA at 12.6V, extending parking surveillance from hours to days; Hybrid Parking Mode auto-transitions from continuous recording to ultra-low-power standby based on battery voltage or time threshold
  • Modular 2CH-to-3CH expandability — add a 210° fisheye cabin camera, telephoto A329T, or waterproof exterior A329WW cameras without hardware replacement; supports external SSD storage up to 4TB for weeks of uninterrupted dual-channel recording
