The Nextbase 622GW is the British brand’s flagship dash cam, and it comes loaded with features that no other camera in its class offers — including a built-in Emergency SOS system that can automatically alert emergency services if you’re in a serious accident. Combined with 4K recording and optical image stabilization, it’s one of the most fully-featured dash cams on the market. Here’s our full review.

Video Quality
Daytime Performance
The 622GW’s 4K 30fps sensor delivers the sharpest footage in its class. License plates are readable at 60+ feet, the 140° wide angle captures full intersections, and Nextbase’s image processing renders color with impressive accuracy. The built-in polarizing filter (CPL) eliminates windshield glare and reflections — a feature that usually costs $20–30 extra as an add-on accessory on competing cameras. Footage taken through a clean windshield with the CPL filter engaged is noticeably cleaner than anything produced by 1440p competitors. Exposure transitions between tunnels and bright sunlight are handled well by the HDR processing, maintaining detail simultaneously in sky and shadow.
Night Vision
4K at night is harder than 4K in daylight, and the 622GW handles it better than most. The Sony IMX415 sensor produces cleaner low-light footage than most 1440p cameras at night, with license plates readable under streetlight conditions beyond 40 feet. Extreme Weather Mode adjusts image parameters for heavy rain, fog, or snow conditions — a thoughtful addition for drivers in northern climates. In true darkness without streetlights, footage grain is visible (as expected from any fixed-aperture camera), but the detail is above average for the class.
Emergency SOS: The Standout Feature
Emergency SOS is the 622GW’s most-discussed feature and genuinely differentiated capability. If the camera detects airbag deployment or a severe impact, it automatically contacts emergency services with your GPS location — even if you’re unconscious and can’t call for help yourself. After the trigger, a 30-second countdown gives you time to cancel a false alarm before the call goes out.
This requires a Nextbase Connected account (subscription available) and a paired smartphone for cellular data. In practice, the feature needs setup: link the SOS profile with your medical information (blood type, allergies, vehicle make/model), your emergency contacts, and your next of kin. That setup takes about 10 minutes and dramatically improves the usefulness of an emergency call. For solo commuters, long-distance drivers, or people who drive frequently in remote areas, Emergency SOS is a meaningful real-world safety net that no other sub-$300 dash cam offers.
What’s in the Box
The 622GW ships with a coiled 12V car charger cable (approximately 13 feet extended), a windshield adhesive mount, a magnetic quick-release mount adapter, cable management clips, and a microSD card reader for desktop file transfer. Importantly, Nextbase includes a 32GB microSD card with the 622GW — a welcome inclusion that most competitors skip. For 4K continuous recording, a 128GB U3 endurance card is recommended for longer trips. Nextbase sells branded cards, or the Samsung PRO Endurance series is well-matched to the write demands.
The optional Rear View camera (Nextbase 622GW Rear) connects via a dedicated port on the camera body. The optional interior-facing camera is also available for rideshare monitoring. Both accessories are Nextbase proprietary and add genuine dual-channel capability without the complexity of running separate cables.
Alexa Voice Control
The 622GW includes Amazon Alexa built-in via the Nextbase Connected app — you can ask Alexa to save a clip, take a photo, or check your speed without touching the camera or your phone. In testing, the voice recognition works reliably at highway speeds with the windows up. The integration extends to standard Alexa functionality (weather, navigation prompts, music control) over your phone’s data connection.
Voice control is primarily a convenience feature rather than a safety essential, but it reduces the need to handle the camera while driving — which is when you’d most want to save a clip after a near-miss incident. The feature requires the Nextbase Connected app and a Bluetooth-paired phone.
Build Quality and Installation
The 622GW has premium fit and finish that matches its price. The housing is denser than budget cameras, the cable connections are tight with satisfying positive locking, and the magnetic quick-release mount is genuinely easy to use — attach and remove the camera in under two seconds. The 3-inch IPS touchscreen is bright and responsive, useful for playback review or settings adjustments without needing the app.
Installation via the magnetic windshield mount is straightforward: route the cable behind the headliner to the A-pillar, down to the footwell, and into the 12V socket or a hardwire kit. The coiled cable keeps the install tidy. For parking mode functionality, the hardwire kit ($25) connects to the fuse box. Total installation time for a tidy hardwired setup: approximately 45–60 minutes for a first-timer.
How It Compares
| Camera | Price | Resolution | Emergency SOS | CPL Filter | Includes SD Card |
|---|---|---|---|---|---|
| Nextbase 622GW | ~$230 | 4K 30fps | Yes | Built-in | Yes (32GB) |
| Viofo A329S | ~$200 | 4K + 2K rear | No | No | No |
| BlackVue DR970X | ~$350 | 4K + 4K rear | No | No | No |
| Garmin Dash Cam 67W | ~$130 | 1440p | No | No | No |
| Thinkware Q200 | ~$200 | 2K QHD | No | No | No |
The 622GW is the only consumer dash cam under $300 with Emergency SOS, and one of very few with a built-in CPL filter at any price. If those two features matter to you, it’s the obvious choice. If you want dual-channel front and rear for the same budget, the Viofo A329S delivers 4K front + 2K rear for $30 less — but without SOS or CPL. For pure parking mode protection with RADAR sensing, see the Thinkware Q200.
Who Should Buy the Nextbase 622GW?
The 622GW is ideal for drivers who prioritize absolute video quality and unique safety features over raw camera count. Emergency SOS is a particularly strong case for solo commuters, parents equipping a teenager’s car, or frequent long-distance drivers who spend time in areas with limited cell service. The built-in CPL filter and included SD card make it the most complete out-of-the-box package in the premium single-channel category.
Skip it if your priority is dual-channel front and rear coverage — at $230, you’re close to the Viofo A329S territory where 4K front and 2K rear is achievable for less. But for sheer single-lens 4K quality with the best safety features in the class, the 622GW is the top pick.
FAQ
Does the Nextbase 622GW come with an SD card?
Yes — Nextbase includes a 32GB microSD card in the box. For longer trips or 4K recording sessions, a 128GB U3 endurance card (Samsung PRO Endurance or Nextbase branded) is recommended to avoid running out of storage on loop.
Does Emergency SOS require a subscription?
Emergency SOS requires the Nextbase Connected service and a paired smartphone for data. Nextbase Connected also adds cloud backup, remote live view, and GPS tracking. Some features are free; enhanced monitoring features require a paid tier. Check Nextbase’s current Connected pricing as plans have evolved since launch.
Can I add a rear camera to the Nextbase 622GW?
Yes — the 622GW has a dedicated rear camera port and is compatible with Nextbase’s Rear View, Cabin View, and Rear Window cameras. All are proprietary Nextbase accessories. For simultaneous front and rear recording, add a Nextbase Rear camera (~$70–$100).
What is the CPL filter on the Nextbase 622GW?
CPL (Circular Polarizing Lens) filter reduces windshield glare and dashboard reflections in the recorded footage. On the 622GW it’s built-in and adjustable — rotate the lens ring to dial out reflections. On other cameras it’s a $20–30 add-on accessory. The difference in footage clarity, especially on sunny days or with a dark dashboard, is significant.
Does the Nextbase 622GW work in cold climates?
Yes — Nextbase’s Extreme Weather Mode adjusts image parameters for low-visibility conditions (rain, fog, heavy snow). The camera operates down to -20°C. The 622GW uses an internal supercapacitor for power management rather than a standard lithium battery, which makes it more resistant to temperature extremes than battery-based cameras.
Verdict: 4.5/5
The Nextbase 622GW earns its premium price with best-in-class 4K video quality, a unique built-in CPL filter, Emergency SOS capability, and Alexa voice control — features no single competitor bundles at this price. The included SD card and polished quick-release mount round out an impressive package. The main trade-off is that it’s front-only; if rear coverage is a priority, step up to a dual-channel system. But for single-channel excellence with genuine safety innovations, the 622GW is the benchmark.

The 622GW is the right choice for drivers who want the most feature-complete dash cam available regardless of price, and who specifically value the Emergency SOS capability. It’s also ideal for Alexa users who want their car fully integrated with their smart home ecosystem. If 4K resolution and image stabilization are priorities, this delivers both.
If Emergency SOS doesn’t appeal to you and you’re primarily focused on video quality per dollar, competitors like the Viofo A229 Plus offer comparable 4K footage at a significantly lower price.
