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.

The camera is great. I would prefer a different mounting option.
I have not been able to make the hybrid parking mode work. it keeps asking me to setup the battery protection. I have set it up like fifteen different times, still no luck.
Thanks for your review, Bruce! We’re glad to hear you’re happy with the A329S overall, and we appreciate the feedback on the mounting option.
For the hybrid parking mode issue, please reach out to our support team so we can help review the setup with you. That battery protection message may be related to the hardwire or battery configuration, and we’d be happy to help get it working properly.
Just installed this in my car. Easy to install and hid the wires. The best part is that you can just plug the wire in to the usb c jack and not use the cigarette light plug. Great picture image and small unit that doesn’t stand out
Thanks for the review, Calvin! We’re glad to hear the A329S was easy to install and that you were able to get a clean setup with the wiring hidden. Great to know you’re enjoying the compact design, USB-C power option, and picture quality.
I wish you can access functions with or without the app..watching videos etc.
Had it for 2 weeks now and still testing different setup.
Great dashcam. Great video and pictures quality on the front, the inside and the rear cam.Had a professionnel installation for top notch install.
Well made. Excellent parking mode choice with the HK6 kit.
Expensive but worth it.
Thanks for the review, Alan! We’re glad to hear the A329S has been performing well across all cameras and that the professional install gave you a clean setup. Great to know you’re making the most of the parking mode with the HK6 kit as well.
I worked with this company to purchase my camera. What a great group of people. They were very attentive to my needs. The camera arrived very fast as promised. The quality of the camera is impressive as is the interface. Thank-you for your excellent customer service.
Thanks for the review, Steve! We’re glad to hear you had a great experience with our team and that the A329T arrived quickly and met your expectations. We really appreciate your kind words about both the camera and our customer service.
Really nice dashcam. Lots of features and simple to use. The instructions are easy to follow and installation was a breeze. Video quality is excellent. My biggest complaint is that it uses sticky tape instead of a solid or suction mount. In hot climates this may not stick.
Thanks for the review! We’re glad to hear the A329S has been easy to install and that you’re enjoying the features and video quality.
Just to note, the adhesive mount is actually designed to hold up better than suction mounts, especially in heat, since it provides a more secure and consistent bond over time.
I love the A329T. It's video recording quality is better than my older A229 Pro and it doesn't get as hot. I'm amazed how well the front telephoto zoom cam picks up license plates.Viofo hit a home run with the new A329T series
Thanks for the great review, Samuel! We’re glad to hear the A329T has been a strong upgrade for you and that the video quality and telephoto camera are making a noticeable difference. Happy to know it’s running cooler as well.
I’ve come to the Viofo A329S after using numerous BlackVue cameras over the past 12 years. While the A329S performs well under the hood, the build quality feels a bit "cheap" to the touch when compared to the premium, robust feel I’ve grown accustomed to with BlackVue.
I have had the system installed for three days, and I’ve encountered a few frustrating hurdles:
GPS Connectivity Issues: Despite the GPS settings being active and the camera properly docked to the GPS window mount, playback on the Viofo PC software fails to show movement. My speed remains at zero and the location stays static at the coordinates where I first installed the system.
Software Limitations: Coming from the BlackVue ecosystem, I am used to a seamless continuous playback of all files. The Viofo software, by contrast, seems to only allow a limited number of files to load at once, making it difficult to review long trips.
App Intuition: Today, while using the Android app, I found the file organization confusing. While I could locate footage from earlier in the day, I was completely unable to find the clips from the minutes immediately preceding my connection to the camera.
Since I am new to the Viofo system, some of these issues may be due to my own learning curve. I’m hoping that with more time, the interface will become more intuitive and these technical glitches will be resolved.
Thanks for the detailed feedback, Pebo. We really appreciate you taking the time to share your early impressions, especially coming from long-term BlackVue use.
VIOFO positions the A329S in the 'affordable premium' segment, so some compromises in exterior materials are made to keep pricing relatively low, as the price to performance ratio is the major focus.
Regarding the GPS behavior, this is most often resolved with a firmware update. You can update directly through the newer VIOFO Dashcam app, which has replaced the older VIOFO app and offers a more streamlined experience. If you are still using the older app, we recommend switching to the updated one. Firmware can also be installed manually via the SD card if needed.
As for file browsing and playback, the new app significantly improves navigation and overall usability compared to previous versions. There can definitely be a learning curve when switching ecosystems, but many users find the experience more intuitive on the new app.
If the GPS issue persists after updating, or if anything feels off, please reach out to our team. We are always happy to assist with technical troubleshooting or warranty support to make sure your system is working as it should.
I bought this and a rear camera separately and the video quality is really good
I decided to try this camdash and truly enjoy its features plus hands free voice control.
Thanks for the review, Luis! We’re glad to hear you’re enjoying the A329S and making good use of the hands-free voice control and features.
This is one of the best dash cam I ever owned. The telephoto camera is a game changer for catching license plates. It’s expensive, but it worth it 100%.
Thanks for the great review, Dave! We’re glad to hear the A329T stands out as one of the best you’ve owned and that the telephoto camera has been a game changer for capturing license plates.
Order received in a timely manner and everything was/is intact. Can't ask for more than that.
Replaced a BlackVue DR900S-2CH. Easy enough to install, I could reuse the rear camera cable from the BlackVue.
I did end up disabling HDR to use 60fps on the main camera. Didn't see much difference with HDR during the day.
Thanks for your review! We’re glad to hear the A329S delivered excellent video quality and that the install was straightforward for you. Appreciate you sharing your experience with the HDR and frame rate settings as well, that kind of insight is helpful for other customers.
I have installed a 129, 2x 229s and now a A329. They all basically install exactly the same but you can see that things have ivastly mproved over time. Even the feature set is now light years ahead, not to mention the video quality. I particularly like the new parking modes to extend recording time, as it is getting smarter and smarter. I can't wait for an A429 4 channel with 2 front fender sideview cameras. I am a bit puzzeled as to why no one does this, yet, except Tesla, from the factory. Stick with Viofo as I have experience with Blackview and some brand Xs and just don't go there.
Thanks for the great review, Alan! We’re glad to hear you’ve had such a positive experience across multiple VIOFO models and that the A329S continues to impress with its smarter parking modes and video quality.

Thanks for your review, Ron! We’re glad to hear you had a great experience with our team and that they were able to assist you knowledgeably.
Amazing video quality. Easy enough set up. One of the problems I had with the old Garmin dashcam was connecting to the app. It was a constant challenge. No such issues at all with the Viofo app. Was a quick and efficent stable connection. A shout out to Blackbox for their delivery updates. Came right on schedule.
Thanks for your review, Felician! We’re glad to hear the A329S has been easy to set up and that the app connection has been smooth compared to your old dash cam. Happy to know our delivery updates were helpful too.
