CarCareTruth's Analysis
Last reviewed May 25, 2026
TL;DR Dashcamtalk.com named the A329S the best video quality in the category as of September 2025 — front plate legibility confirmed clearly in community footage comparisons. Front night footage rated strong by dashcamtalk.com; rear night is 3.0/5 per dashboardcamerareviews.com ("hit and miss" beyond the immediately following car). Buffered parking modes available but the hardwire kit is sold separately. Supercapacitor design — no lithium battery. FCC-only, no UL/ETL electrical safety certification.
What it is and how it performs
The A329S records 4K 60fps front and 2K rear using dual Sony STARVIS 2 sensors on both channels. Note: 4K 60fps and HDR cannot run simultaneously — HDR drops the front to 4K 30fps. Dashcamtalk.com footage comparisons confirm benchmark-class plate legibility in daylight and "bright and clear" low-light front footage; rear night performance rates 3.0/5 independently ("hit and miss" for vehicles beyond the car immediately behind). Parking mode offers five modes including buffered capture, but the required hardwire kit (HK4 or HK6) is sold separately. The supercapacitor eliminates battery thermal degradation in hot-car conditions — a documented failure mode for lithium-cell competitors. The VIOFO app enables Wi-Fi 6 file transfers at 30MB/s but carries a 1.9/5 App Store rating on 712 reviews, with live feed functionality reported unreliable.
Who should buy this — and who should skip it
Strongest match for drivers who prioritize community-confirmed footage quality front and rear and want supercapacitor reliability in hot climates — dashcamtalk.com's footage benchmark endorsement is well-sourced. Skip it if the companion app is important to your workflow: the 1.9/5 App Store rating reflects documented live-feed failures that hardware recording does not fix. Also skip if you need parking mode without an additional purchase — the hardwire kit is not included.
Safety and environmental impact
No chemical exposure risk during normal installation or use. The supercapacitor contains no lithium and qualifies for standard electronics recycling (Best Buy, municipal e-waste drop-off); no VIOFO manufacturer take-back program is documented. No independent UL or ETL electrical safety certification — FCC compliance covers radio emissions only. No active CPSC recall (checked 2026-05-24).
Frequently asked questions
Does the VIOFO A329S have a lithium battery?▾
No. The A329S uses a supercapacitor instead of a lithium battery. This means no thermal degradation in hot-car environments — a common failure mode for dash cams with lithium cells parked in direct sunlight.
Is a hardwire kit included with the A329S?▾
No. The A329S includes a car charger, CPL filter, rear coaxial cable, and trim removal tool — but not a hardwire kit. Parking mode requires the HK4 (basic) or HK6 (adds Bluetooth voltage display and Hybrid Parking Mode) kit, sold separately.
Does the 4K 60fps mode work with HDR enabled?▾
No. According to the product listing, the front camera's 4K 60fps mode is not available while HDR is enabled. In HDR mode, the front records at 4K 30fps. You can use 4K 60fps or HDR — not both simultaneously.
What is the maximum storage capacity for the A329S?▾
The A329S supports microSD cards up to 512GB or external SSDs up to 4TB. SSD storage requires a hardwire cable rather than the standard car charger.

- •[Advanced Dual STARVIS 2 Sensors] The A329S 4K dash cam features dual STARVIS 2 sensors. The front camera deploys a STARVIS 2 IMX678 image sensor that packs in more pixels for greater clarity and detail, achieving less noise in low light and less motion blur in fast motion. The rear camera deploys a STARVIS 2 IMX675 image sensor, featuring an impressive 2.5 times wider dynamic range than the STARVIS pixel of the same size, capturing exceptionally clear and sharp videos.
- •[Impact Detection Power Saving Parking Mode] The A329S dashcam supports an ultra-low-power parking mode to prevent battery drain. Once a collision is detected, it starts recording instantly. These features minimize battery drain while ensuring continuous monitoring when your car is parked. These modes can be easily activated using the HK4/HK6 Hardwire Kit(*Note: The hardwire kit is not included).
- •[Next-Gen Wi-Fi 6 Technology] A329S front and rear cam is powered by advanced Wi-Fi 6 technology, which boosts operation speeds by 3 times in the 5GHz band, up to 30MB/s.

This ensures you never miss vital evidence while on the road.
- •[Simple Installation Without Interference] A329S 4K 60fps dash cam features premium super slim 2.8mm coaxial cable and miniature connectors for a neatly hidden installation. The coaxial cable is less susceptible to electromagnetic and radio-frequency interference, avoiding disturbance to other in-car electronic devices as well. What's more, the cable enables higher bandwidth transmission and transfer rates, regardless of its length.
- •[Hands-Free Smart Voice Control] Focus solely on the road with voice commands that let you start/stop recording, take photos, and turn on/off Wi-Fi—all while keeping your hands on the wheel. Stay informed with clear notifications about settings changes and memory card errors.

- •[Included Anti-Glare CPL & Versatile Cable Options] A CPL (Circular Polarizing Lens) is included and attached to the front lens of the dash cam, effectively reducing reflections and glare from glass and road surfaces. This results in a significant enhancement of image quality and contrast across various scenarios. The camera comes standard with a 6M rear cable. If you require a longer customized 8M or 10M rear cable for your vehicle, you can find it on the VIOFO website.

Impressed and Very Happy!
Impressed and Very Happy! Installed in 2025 Honda CRV EX-L, along with Dongar DCA-8A cable, CP lenses for front and rear cameras:1) A329S - Straightforward installation, and I used the static sheets for easier removal if it becomes necessary. Works like a charm producing excellent videos with superb resolution and contrast. The iPhone app is a little touchy on setup if you have CarPlay active and want a WiFI connection. RTFM.2) Dongar DCA-8A cable makes for a very professional and neat installation versus powering via a cig lighter, or running hardwiring thru the pillars and liners. Considering that this is most likely among their most popular cable adapters, I was surprised that Dongar does not yet have an on-line video available ("in progress"). Be sure you hook this into the powered MIRROR connector, as opposed to the exact same blue 8-pin connector that is available in the overhead console -- the console connector will not power the A329S.3) CP Lenses - The forward facing camera comes with a CP lens attachment, but an optional CP lens must be purchased for the rear lens. The circular polarizing (CP) lens covers are VERY effective at reducing glare, and optimizing contrast. I would strongly recommend it.Bottom Line: I am VERY happy with the ease of installation, operation, and high quality of the video.
