The VIOFO A329S 2CH pushes the boundaries of dash cam performance. The front camera utilizes the 8MP Starvis 2 IMX678 to record at a stunning 4K UHD resolution at 60FPS. This high frame rate captures fast-moving objects with significantly less motion blur than standard 30fps cameras.
The rear camera is equally impressive, sporting the Starvis 2 IMX675. This ensures that vehicles behind you are captured in sharp 2K clarity. By equipping the A329S 2CH with Sony STARVIS 2 technology, VIOFO guarantees superior dynamic range and 4K+2K performance. See more high-performance models in our VIOFO Collection.
Never worry about running out of space again. The A329S is the first dashcam to natively support portable external SSD storage up to 4TB via its VIOFO Type-C port. This allows you to store weeks of high-bitrate 4K footage without constantly looping over old files—perfect for long road trips using your dash camera.
In addition to SSD storage support, the unit accepts a standard microSD card up to 512GB. You can choose the storage solution that fits your needs. This robust flexibility makes the A329 powerhouse for data retention and 4K video security.
Driving at night requires technology that can handle extreme contrast. The VIOFO A329S features advanced HDR (High Dynamic Range) capabilities on both front and rear units (when set to 30fps). This technology automatically balances bright headlights and dark shadows day and night.
Even in low-light environments, the STARVIS 2 sensors excel at reducing noise. Whether you choose the fluidity of 60FPS for daytime driving or the balanced exposure of HDR for night driving, this dash cam adapts to ensure your image sensor captures usable footage.
The A329S integrates cutting-edge Wi-Fi 6 technology, offering faster and more stable connections than ever before. This allows you to download large 4K front video files to your smartphone via the VIOFO App in seconds, rather than minutes.
For added convenience, the system supports advanced Voice Control. You can issue simple commands like "Take Photo" or "Lock the Video" to operate the dashcam hands-free. This ensures you can save emergency clips instantly while keeping your focus on the road.
Secure your vehicle 24/7 with the new Hardwire Kit. The A329S 2CH offers a comprehensive suite of Parking Mode options, including Hybrid Parking Recording, which automatically switches to Low Power Impact monitoring. This ensures impact detection wakes the camera instantly upon collision.
To extend your Parking Mode duration without straining your vehicle's battery, we recommend pairing this system with a dedicated battery pack like the BlackboxMyCar PowerCell 8. This setup allows the Sony STARVIS 2 sensor to monitor your car for days.

Who is the VIOFO A329S 2CH best suited for?
The VIOFO A329S 2CH targets premium drivers who want a compact dash cam that still delivers 4K detail up front and 2K performance at the back. It suits commuters, road-trippers, and anyone who wants more than a basic dash camera without the extra complexity of a 3-channel system. If you want a modern, fast, front and rear setup that can keep up with new vehicles, this is a strong option.
How do 4K 60FPS and 4K 30FPS modes help in real driving?
On the front camera, 4K 60FPS lets the dash cam capture motion very smoothly, which helps reduce motion blur when driving at speed or during quick maneuvers. 4K 30FPS is available when you want to save a bit of space on your card while still keeping excellent sharpness. Either way, you get 4K detail for reading plates and signs, backed up by HDR modes in supported combinations.
What makes the STARVIS 2 sensors a big deal for this dashcam?
The A329S 2CH is built around STARVIS 2 parts like STARVIS 2 IMX678 and STARVIS 2 IMX675, plus a Sony STARVIS 2 sensor design philosophy. These sensor choices help the dash cam stay cleaner and more detailed in low light, with better control over bright highlights and dark shadows. That is what makes footage from STARVIS 2 sensors easier to trust when you actually need it after an incident.
How does parking mode work and what hardware do I need?
To unlock parking mode features such as hybrid parking recording, low power impact monitoring, and buffered impact detection, you will want a compatible hardwire kit from the VIOFO Type-C line connected to your fuse box. This lets the camera know when the engine is off and manage voltage safely. Once wired, your dash cam can keep capturing events when parked at home, the office, or on city streets.
What storage is recommended for 4K+2K recording on this dash cam?
Because you are running 4K up front and 2K at the back, it is important to use a high-endurance microSD sized for your driving. The A329 family’s support for larger cards and even SSD storage on certain models shows it is built for heavy use. For the A329S 2CH, starting with a quality high-endurance card and formatting it regularly is the best way to keep this dashcam recording reliably.
How does Wi-Fi 6 and the VIOFO app make daily use easier?
With Wi-Fi 6, the VIOFO A329S 2CH can connect more quickly and transfer clips faster to your phone through the VIOFO app. That matters when you are pulling high-bitrate 4K files after a close call or an incident. Instead of juggling cards and adapters, you can stand by the car, grab the clip with your phone, and send it to insurance or share it as needed.
How does this compare to other A329 variants like A329S 3CH?
Within the A329 line, the A329S 2CH is the focused dual-channel option that pairs 4K front with 2K rear, while the 3-channel versions add a cabin camera for more angles. If you do not need interior recording, the 2-channel setup keeps installation and management simpler. It is a good way to step into the A329 family’s STARVIS 2 performance and 4K+2K flexibility without committing to a full three-camera layout.
