Viofo A329S vs. Nextbase 622GW Dash Cam: Head-to-Head 2026

It ships with a front camera capable of 4K at 30fps, a rear interior cabin camera, and a rear-facing exterior camera. The Sony STARVIS 2 sensor is present in the front unit, which is the current benchmark for low-light performance in consumer dash cams. The A329S records to a microSD card, supports Wi-Fi and GPS, and draws power via a hardwire kit or the included cigarette lighter cable. Total storage capacity tops out at 256GB depending on the card you install. The Nextbase 622GW is a single-channel front camera that shoots 4K at 30fps using its own high-sensitivity sensor. It adds Bluetooth 5.0, Wi-Fi, built-in Amazon Alexa, image stabilization (Nextbase calls it "Image Stabilization IS"), and an optional Rear Window Camera accessory sold separately. It also supports Nextbase's Emergency SOS feature, which can detect a crash and alert emergency services. Max card support is 128GB with a Nextbase-branded card, though third-party cards up to that capacity generally work. On paper the A329S delivers more camera coverage out of the box. The 622GW counters with smarter software features and a more polished ecosystem. Neither camera is wrong — they just serve different priorities.

In direct daylight testing, most users would struggle to tell the footage apart. At night, the Viofo A329S pulls ahead. The Sony STARVIS 2 sensor is purpose-built for low-light capture, and it shows. Street lighting, headlights, and illuminated signage are rendered with noticeably less noise and better color fidelity than the 622GW. If you do a lot of night driving or park in poorly lit areas, this gap is meaningful. The Nextbase 622GW's image stabilization is a real differentiator on rough roads. If you drive on potholed urban streets or uneven country roads, the 622GW footage is smoother and easier to watch back. The A329S does not offer electronic image stabilization, so footage on rough surfaces can look shakier, particularly at higher bitrates. Parking mode is available on both cameras but requires a hardwire kit on the A329S and Nextbase's own Hardwire Kit for the 622GW. The A329S uses buffered parking mode with motion and impact detection. The 622GW uses time-lapse and motion detection. Neither is dramatically better than the other in parking surveillance, though the A329S's three-channel coverage means you are watching the cabin and rear simultaneously — a meaningful advantage if vehicle break-ins are a concern. For the rear and interior channels on the A329S, video quality is competent but not exceptional. The front camera is clearly where Viofo invested its sensor budget. The optional 622GW rear window camera, when added, shoots at 1080p and integrates cleanly into the 622GW app.

Plugging into the cigarette lighter socket gets you running in under ten minutes. If you want hardwiring for parking mode, Nextbase sells a dedicated kit that connects to your fuse box — it is a job most confident DIYers can handle in an hour. The Viofo A329S is more involved. Running three camera channels means routing cables to the rear of the vehicle and, if you opt for the cabin camera, positioning it to capture the interior without obstructing the driver's view. The included cables are long enough for most vehicles, but you will spend time tucking wires into headliner trim and door seals. Hardwiring all three channels adds another layer of complexity. Viofo provides solid documentation, but this is realistically a two-hour job for someone who has done it before, or a professional install if you have not. Both cameras use GPS for speed logging and location data in footage, which is useful for insurance claims. The A329S's GPS module is built into the front camera unit. The 622GW's GPS is also integrated. Neither requires an external GPS antenna. If you want a dash cam you can move between vehicles easily, the 622GW's magnetic quick-release mount is a clear advantage. The A329S is better treated as a permanent fixture once installed.

The Emergency SOS feature is arguably the most distinctive: after a detected impact, if you are unresponsive, the camera can send your GPS location and vehicle details to emergency services. This requires a subscription after a trial period, which is worth factoring into total cost of ownership. The Viofo app is functional but more utilitarian. Wi-Fi connectivity works reliably for downloading clips and changing settings, but the interface is less polished than Nextbase's. There is no cloud or emergency alert feature built into the A329S ecosystem. What you get instead is a camera that does its core job — recording clean, multi-channel footage — without locking you into a subscription. Bluetooth is present on the 622GW and absent on the A329S. In practice, Bluetooth on dash cams is mainly used for initial pairing and firmware updates on the Nextbase platform, so it is not a daily-use differentiator for most people. If you value a connected, feature-rich ecosystem and do not mind the potential for ongoing subscription costs, the 622GW's software platform is genuinely better. If you want a camera that records reliably without any cloud dependency, the A329S is the cleaner choice.

When you factor in that the 622GW's rear camera is a separate purchase, and that Emergency SOS runs on a subscription after the trial, the total cost of ownership for the 622GW can exceed the A329S for buyers who want full coverage and connected features. MicroSD cards are an additional cost for the A329S — Viofo recommends high-endurance cards, and a quality 128GB or 256GB card adds to the initial outlay. Nextbase recommends its own branded cards for the 622GW, which are priced at a premium compared to third-party alternatives. Hardwire kits are sold separately for both cameras. Professional installation, if you go that route, will cost roughly the same regardless of which camera you choose. For buyers on a strict budget who want the most camera coverage per dollar, the A329S is the better value proposition. For buyers who want a single-channel front camera with premium software and are willing to pay for extras over time, the 622GW's pricing is competitive within its category. If you are shopping for other automotive accessories to pair with your new dash cam, it is worth browsing the full automotive category for complementary picks like jump starters, OBD2 scanners, and car care products that round out a well-equipped vehicle setup.

If your primary goal is comprehensive video evidence in the event of an accident or break-in, the A329S delivers more of it. Buy the Viofo A329S if you want full front, cabin, and rear coverage out of the box, prioritize night-time video quality, plan to hardwire the camera permanently, and want to avoid any ongoing subscription costs. It is the right call for commuters, rideshare drivers, and anyone who has had a vehicle broken into. Buy the Nextbase 622GW if you drive a single vehicle, want the easiest possible installation and removal, value image stabilization for rough road conditions, and find the Emergency SOS feature genuinely compelling for your lifestyle. It is also the better choice if you want a polished app experience and are comfortable with the Nextbase ecosystem. Drivers who frequently move their camera between vehicles will appreciate the magnetic mount more than almost any other feature either camera offers. Neither camera is a bad buy. The 622GW is one of the best single-channel dash cams available. But in a direct head-to-head where coverage, low-light performance, and total value are the deciding factors, the A329S takes the win. Install it, hardwire it, and forget about it — it will be there when you need it.
