Viofo A329S (2CH) 4K 60fps Dash Cam
Overview
The Viofo A329S is the 2025 flagship dash cam that pushes the boundaries of consumer dash cam video quality with the industry's first 4K 60fps front recording using a Sony STARVIS 2 IMX678 sensor. Available in 1CH, 2CH, and 3CH configurations with an expandable architecture, it features dual STARVIS 2 sensors across all channels for consistent night-time performance, Wi-Fi 6 for high-speed app connectivity, and groundbreaking support for external SSD storage up to 4TB via USB 3.0. The supercapacitor-based power system ensures reliable operation in extreme temperatures (-20°C to 65°C) while the ultra-low-power buffered parking mode provides comprehensive 24/7 vehicle protection.
