When to Choose VIOFO A329S 2CH
Enthusiasts who want the highest frame rate 4K recording with SSD storage reliability
The VIOFO A329S 2CH pushes the boundaries with 4K 60fps recording and SSD storage support. The smoothest footage in our roundup makes license plates and details crystal clear in motion. SSD storage eliminates microSD card failures, though the added bulk and $430 price reflect its enthusiast positioning.
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
- Sony STARVIS 2 sensor with excellent HDR performance
Limitations
- Rear camera is 2K, not 4K — asymmetric channel quality
- SSD enclosure adds bulk and requires separate purchase
- Smart features are basic compared to cloud-connected competitors
When to Choose Miofive S1 Ultra
Value-focused buyers who want true dual 4K with built-in storage and no microSD hassles
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
