When to Choose VIOFO A229 Ultra 2CH
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.

- 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 Miofive S1 Ultra

The Miofive S1 Ultra offers remarkable value with dual 4K cameras and built-in eMMC storage for $200. The elimination of microSD cards is a real reliability advantage. The app needs polish, but for pure hardware value, nothing else in this price range offers dual 4K.
Strengths
- Dual 4K front and rear at just $200 — best resolution-per-dollar in the roundup
- Built-in eMMC storage eliminates microSD card failures
- 5GHz Wi-Fi for fast wireless footage downloads
- Sony STARVIS 2 IMX678 sensor for excellent low-light performance
Limitations
- Fixed internal storage cannot be expanded or replaced
- App can be slow and occasionally disconnects during transfers
- Newer brand with less track record than VIOFO or BlackVue
