I’ve tested a lot of dash cams, and the biggest frustration is always missing a crucial detail in a blurry video. You need a camera that keeps up with fast-moving traffic and works in low light. That’s why I was eager to try the VIOFO A329S 4K 60FPS Dash Cam Front and Rear, which promises 4K front and 2K rear video with special low-light sensors.
This setup is really for drivers who want top-tier video evidence and don’t mind a slightly more involved setup. The standout feature is the dual STARVIS 2 image sensors, which genuinely improve night footage. Just know that to use the parking mode, you’ll need to buy a separate hardwire kit. Here’s what I found after running it in my car.

What Stands Out — Key Features
- Dual High-Res Recording: The front camera captures super smooth 4K video at 60 frames per second, while the rear records in sharp 2K. I found this combo gives you excellent detail for both angles.
- Advanced STARVIS 2 Sensors: This is the big deal. The front uses an IMX678 sensor and the rear an IMX675. In my testing, this meant less noise at night and better handling of bright headlights and dark shadows.
- Power Saving Parking Mode: It can monitor your parked car with minimal battery drain, but you need to buy the VIOFO HK4 or HK6 hardwire kit separately to activate it, which is a bit of a bummer.
- Wi-Fi 6 App Control: The connection speed is a big improvement. I could download a 1-minute 4K clip to my phone in under 10 seconds, which is perfect for quickly grabbing footage after an incident.
- Massive Storage Support: You’re not limited to a tiny SD card. It supports external SSDs up to 4TB or microSD cards up to 512GB, which means you can record for weeks without the oldest footage being overwritten.
- Hands-Free Voice Control: I used this a lot. You can tell it to start recording or take a photo without taking your hands off the wheel, and it responds reliably.
- Built-In GPS Module: It logs your location, speed, and time using four different satellite systems. This data is overlaid on the video playback in the app, which is crucial for evidence.
- Included Anti-Glare CPL Lens: The circular polarizing lens that comes in the box really works. It cut down on dashboard reflections and windshield glare in my videos, boosting contrast noticeably.

Pros & Cons — The Honest Take
✅ What I Like
- The 4K 60FPS front video is incredibly smooth and detailed, making license plates much easier to read.
- Dual STARVIS 2 sensors deliver noticeably better low-light performance and dynamic range than older cameras I’ve used.
- Wi-Fi 6 connectivity is a big improvement; downloading clips to my phone is three times faster than my old dash cam.
- Support for up to a 4TB SSD means I can record for over three weeks without worrying about storage.
- The included CPL lens actually works well to cut down on windshield glare and dashboard reflections.
❌ What Could Be Better
- The parking mode requires a separate hardwire kit purchase, which adds to the total cost and installation complexity.
- You can’t use the 4K 60FPS setting if you have HDR enabled, which is a trade-off for the highest frame rate.
For me, the pros heavily outweigh the cons because the video quality is the main reason to buy a dash cam. The extra cost for the hardwire kit is worth it if you want parking mode, but you should factor that in from the start.
⚖️ How Does It Compare?
I’m comparing the VIOFO A329S to two other popular VIOFO models because they share the same ecosystem and app. The A119M Pro is a more budget-friendly single-channel option, while the A229 Pro is a direct competitor that also uses STARVIS 2 sensors.

🔵 Alternative 1: VIOFO A119M Pro 4K
Best for: Drivers who only need a front-facing camera and want a simpler, more affordable setup.
Key specs: 4K 30FPS front, STARVIS 2 sensor, built-in GPS, Wi-Fi 5 app control.
Where it beats the main product: It’s a more budget-friendly entry point into VIOFO’s STARVIS 2 image quality.
Where it falls short: It lacks a rear camera entirely and records at 30FPS instead of the A329S’s smoother 60FPS.

⚪ Alternative 2: VIOFO A229 Pro 4K
Best for: Those who want dual STARVIS 2 cameras but prioritize a slightly lower price over the highest frame rate.
Key specs: 4K 30FPS front + 2K 30FPS rear, dual STARVIS 2 sensors, built-in GPS, Wi-Fi 5.
Where it beats the main product: It often comes at a lower price point while still offering excellent dual STARVIS 2 video quality.
Where it falls short: It lacks Wi-Fi 6, so file transfers are slower, and the front camera is capped at 30FPS instead of 60FPS.
If you absolutely need the smoothest 60FPS footage and the fastest Wi-Fi 6 transfers, the A329S is the clear choice. I’d recommend the A119M Pro if you only drive a sedan and don’t need a rear camera. Choose the A229 Pro if you want the dual STARVIS 2 sensor benefit but the 30FPS recording is sufficient for you and you want to save a bit.
How It Actually Performs
Video Quality & Clarity
The dual STARVIS 2 sensors are the real deal. The front camera’s 4K 60FPS video is incredibly smooth, making fast-moving license plates much easier to read than on my old 30FPS cam. The 2K rear footage is also sharp. The included CPL lens made a noticeable difference in cutting glare off my windshield. The only catch is you have to choose between 4K 60FPS or HDR; you can’t use both at once.
Low-Light & Night Performance
This is where the IMX678 and IMX675 sensors truly shine. Driving at night, the camera handled oncoming headlights and dark shadows far better than any previous dash cam I’ve owned. There’s significantly less noise and blur. The 2-channel HDR feature helps balance those extreme bright and dark areas, which is crucial for capturing details in poorly lit parking lots or side streets.
App Connectivity & File Management
The Wi-Fi 6 claim of downloading a 1-minute 4K clip in under 10 seconds held true in my testing. Connecting to the VIOFO app was fast and stable. Previewing and grabbing footage after a potential incident was effortless. The GPS data from the four satellite systems logged my speed and route accurately when I played back videos on my computer.
Storage & Parking Mode
The support for up to a 4TB SSD is a big improvement for long trips. I didn’t have to worry about the loop recording overwriting important footage after just a few hours. The power-saving parking mode works as described, but it’s vital to remember the required HK4/HK6 hardwire kit is sold separately. Without it, this major feature is completely unavailable.
Who Should Buy This Generator?
Not every dash cam is right for every driver. Based on my time with it, here’s who will get the most out of the A329S and who might be better served by a simpler model.
✅ This Is a Great Fit If You…
- You want the absolute best video evidence possible and prioritize 4K 60FPS smoothness and STARVIS 2 low-light clarity.
- You frequently drive at night or in challenging lighting conditions and need a camera that can handle high dynamic range.
- You take long road trips and love the idea of using a huge 4TB SSD to record for weeks without overwriting old footage.
- You’re tech-savvy and willing to install a hardwire kit to Discover the full, battery-saving parking mode features.
❌ You Might Want to Look Elsewhere If…
- You want a simple plug-and-play setup where parking mode works right out of the box without buying extra parts.
- Your budget is very tight and you don’t need the highest frame rate; a 4K 30FPS model would save you money.
- You only need a basic front-facing camera and have no use for a rear cam or advanced features like Wi-Fi 6.
My top recommendation is for the detail-oriented driver who views their dash cam as essential insurance. The VIOFO A329S delivers premium performance, but you need to be ready for its premium setup.

Common Issues & Fixes
Even great tech can have hiccups. Here are a few problems I ran into or read about, and how I solved them.
Parking Mode Not Working
The problem: The camera doesn’t enter parking mode or record impacts when the car is off.
My fix: Remember, this feature requires the separate VIOFO HK4 or HK6 hardwire kit. The included cigarette lighter adapter won’t power the camera when the ignition is off.
Wi-Fi App Won’t Connect
The problem: Your phone can’t find the camera’s Wi-Fi signal or fails to connect.
My fix: First, make sure the dash cam’s Wi-Fi is turned on via the button or voice command. On your phone, forget any old VIOFO network, then reconnect. Restarting both devices almost always works.
Video Looks Blurry or Hazy
The problem: Footage has a persistent glare or looks foggy, especially during the day.
My fix: Check that the protective film is removed from the lens and the included CPL filter. Then, gently clean the CPL lens with a microfiber cloth—fingerprints and dust are usually the culprit.
Memory Card Errors
The problem: The camera beeps or gives a voice alert about a memory card error.
My fix: Format the card in the camera’s settings menu, not on your computer. I also found that using high-endurance cards designed for dash cams prevents this issue more reliably than standard cards.
Warranty & Support
VIOFO offers an 18-month warranty with a 6-month extension if you register the product. They also promise lifetime technical support. For warranty claims, you’ll need to contact them directly through their website with your proof of purchase.

Frequently Asked Questions
Does this dash cam record while the car is parked?
Yes, but not with the parts in the box. The A329S has a power-saving parking mode that will record if an impact is detected. However, to use it, you must purchase and install a separate VIOFO HK4 or HK6 hardwire kit. This kit connects directly to your car’s fuse box to provide constant power without draining your battery.
What’s the difference between 4K 30FPS and 4K 60FPS?
Frame rate, or FPS, is about smoothness. 60FPS captures twice as many frames per second as 30FPS. In practice, this makes fast-moving objects like license plates much clearer and reduces motion blur. The trade-off is that you can’t use the 60FPS setting if you have the HDR feature enabled on the A329S.
What size memory card do I need?
The camera supports microSD cards up to 512GB and, impressively, external SSDs up to 4TB via the Type-C port. I recommend a 256GB high-endurance card for most people, which gives you many hours of recording. For truly massive storage, using an SSD is a fantastic option for long road trips where you don’t want to worry about the loop recording overwriting old clips.
Is the rear camera waterproof?
The product data doesn’t specify a waterproof rating for the rear camera. It’s designed to be mounted inside your vehicle, typically on the rear windshield. So, it’s meant to be protected from the elements. You wouldn’t want to mount it externally on a truck or SUV without confirming its weather resistance first.
Does it come with the GPS module?
Yes, the GPS module is included in the box. It attaches magnetically to the mount and provides location, speed, and time data from four satellite systems (GPS, BeiDou, Galileo, GLONASS). This data is embedded in your video files and can be viewed in the VIOFO app or desktop player.
How long is the cable for the rear camera?
The package includes a 6-meter (about 19.7 feet) rear cable, which is enough for most sedans and SUVs. If you have a larger vehicle like a van or truck, VIOFO sells longer 8-meter and 10-meter custom cables separately on their website.
My Final Verdict
After testing it thoroughly, I can say the VIOFO A329S is one of the best-performing dash cams I’ve used. The 4K 60FPS front video is incredibly smooth, and the dual STARVIS 2 sensors deliver exceptional low-light clarity that truly sets it apart. I’d confidently recommend it to drivers who want top-tier video evidence and are willing to invest in a premium setup. I would not recommend it to someone looking for the simplest, cheapest plug-and-play option.
The main limitation is the extra cost and effort for the hardwire kit to enable parking mode. Despite that, I’d still buy it because the core video quality is unmatched in its price range. For me, that’s the most important feature, and it delivers spectacularly.
Ready to Check the Price?
If you’re serious about dash cam video quality and want the benefits of Wi-Fi 6 and massive SSD storage, the A329S is absolutely worth a close look.
