Drivers who want the best dual 4K video quality with excellent night vision at a reasonable price
The VIOFO A229 Ultra 2CH delivers the best bang-for-buck in the dual 4K dash cam segment. Both front and rear cameras use Sony STARVIS 2 sensors for outstanding day and night footage. It lacks cloud features, but for pure video quality and reliability, it's hard to beat at $330.
Strengths
- 4K front + 4K rear with dual Sony STARVIS 2 sensors — best dual resolution available
- Exceptional night vision thanks to STARVIS 2 technology on both channels
- 5GHz Wi-Fi for fast footage transfers to phone
- Reliable supercapacitor design withstands extreme temperatures
Limitations
- No built-in LTE or cloud connectivity — local storage only
- ADAS features are basic compared to Thinkware or BlackVue
- Requires separate hardwire kit for parking mode
When to Choose VIOFO A329S 2CH

Strengths
- 4K at 60fps front camera — smoothest high-resolution footage available
- SSD storage support eliminates microSD reliability issues
- Wi-Fi 6 for dramatically faster file transfers to phone
