Viofo A329S vs Viofo A139 Pro Dash Camera: What Is the Difference?
Choosing the right dash camera can be a challenge, especially when new models offer advanced features over their predecessors. Today, we dive into a detailed comparison of two popular dash cams from Viofo: the A329S and the A139 Pro. Both are solid choices, but understanding their key differences can help you decide if upgrading is worth it.
Understanding the Connections and Ports
Let's start by examining the physical connections on both cameras, as this often determines compatibility and ease of upgrade.
The Viofo A139 Pro features multiple ports:
- Power connection
- Internal camera input
- Rear camera input
- Microphone input (allowing an external microphone for enhanced audio quality)
- Audio-video output (useful if you want to connect an external screen, like in a motorhome)
On the other hand, the Viofo A329S simplifies some connections but adds others:
- Interior camera input
- Micro SD card slot
- Rear camera input
- USB input on the other side for SSD support
One notable difference is the power port location on the A329S, which plugs in at the top on the GPS antenna mount, whereas the A139 Pro's power input is separate from its GPS antenna. The GPS antenna on the A329S is a solid mount, so if removed, the camera loses power entirely.
Video Resolution and Camera Options
A major upgrade with the A329S is in video resolution and camera flexibility:
- The A139 Pro supports 1080p resolution for both interior and rear cameras.
- The A329S supports 2K resolution for rear and interior cameras, offering crisper, more detailed footage.
- If you prefer, the A329S also supports a 2K telephoto camera instead of the interior camera, which allows zooming in on details like license plates — a feature not available on the A139 Pro.
This enhanced resolution and telephoto capability make the A329S stand out for users who want superior video clarity, especially for license plate capture at night or from a distance.
Physical Differences and Usability
Both cameras share similar button layouts on the front:
- Power button (hold 5 seconds to turn off)
- Photo capture button
- Record start/stop button
- Emergency record button
- Microphone toggle button
- Wi-Fi toggle button
However, the A139 Pro does not have a built-in screen, while the A329S offers a slight swivel difference: the A139 Pro swivels side to side, and the A329S swivels up and down. This can affect how you position the camera inside your vehicle.
Connector Compatibility and Upgrading Options
A common question is whether you can upgrade from the A139 Pro to the A329S using existing cables. The answer is nuanced.
While both cameras use coaxial connectors for their cameras, the connectors are physically different sizes and types:
- The A139 Pro connectors are smaller.
- The A329S connectors are larger and incompatible directly with A139 Pro cables.
Therefore, you cannot plug the A329S directly into the A139 Pro's coax cables. However, there are adapter cables available that allow you to use your existing A139 Pro coax cables with the A329S. These adapters, which can be purchased for around $10 each, make it possible to upgrade your camera without rewiring your entire setup.
We tested these adapters for 48 hours to ensure stability and reliability, and they performed flawlessly.
Power Cable Considerations
The original HK3C power cable from the A139 Pro can be used with the A329S, though it is a tight fit. We've successfully installed this cable in upgrades, and many customers have reported it works fine.

Is It Worth Upgrading from the A139 Pro to the A329S?
Ultimately, deciding whether to upgrade depends on your needs and priorities. Here are some factors to consider:
- Storage: The A329S supports SSD storage up to 4TB, which is a significant upgrade over microSD cards for extended recording.
- Resolution: If you want 2K resolution for your interior or rear cameras, the A329S is the clear choice.
- Telephoto Camera: The ability to use a 2K telephoto camera for zooming in on license plates is exclusive to the A329S.
- Multiplex Mode: The A329S can combine front, rear, and interior footage into one video file, which the A139 Pro does not support.
- Low Current Draw Impact Detection: This feature improves parking mode efficiency on the A329S, protecting your vehicle battery better than the A139 Pro.
If these features matter to you, upgrading makes sense. However, if you're happy with your current A139 Pro, it's still a solid dash cam, especially considering it was one of the first to capture license plates well at night when it was released over two years ago.

Conclusion
The Viofo A329S represents a meaningful evolution over the A139 Pro, offering higher resolution, telephoto camera options, SSD support, and advanced features like multiplex video mode and low current impact detection. While the A139 Pro remains a capable and reliable dash cam, if you want the latest technology and enhanced video quality, the A329S is a worthy upgrade.
Ultimately, the choice depends on your specific needs, budget, and how much value you place on the new features. If you decide to upgrade, remember you can leverage adapter cables to use your existing coaxial wiring, making the transition smoother.
