Update: February 2024. Although it was launched back in 2020, the Nextbase 622GW is still the top model in the Nextbase dash cam range. It also continues to occupy the top spot in our list of the best dash cams, thanks to its combination of excellent 4K video quality and a comprehensive feature set, including effective image stabilization and clever what3words integration. Those skills do come with a significant outlay, though. If you’re interested in a Nextbase camera but don’t need all of the features offered by the 622GW, it’s worth looking at its sibling models. For example, the 522GW doesn’t have image stabilization, but it records 2K video and includes support for Alexa. It’s also significantly cheaper than the 622GW. That said, if you’re looking for the very best dash cam you can currently buy, we think the 622GW is worth the money. The rest of this review remains as previously published.

Nextbase has long been at the forefront of advanced dash cam tech, and its latest Nextbase 622GW model comes positively packed with the latest video recording smarts, making it one of the best dash cams on the market.

For a start, the 622GW features a new Ambarella H22 quad-core chipset, which lets you capture pin-sharp 4K footage at 30fps. Better still, the firm has installed a removable polarizing filter, which allows drivers to rotate a bezel on the front of the lens to produce beautiful, glare-free footage.

When recording in normal, well-lit situations, the resulting 4K clips are up there with basic GoPro offerings, and it’s extremely easy to slow playback down to 120fps via a Super Slow Motion setting. 

This is particularly useful for snaring a license plate during a hit-and-run incident, or capturing individual frames during an accident, for example.

There’s also an option to add a rear camera module that films at 1080p/30fps, but this is sold separately. On a positive note, this doesn’t require an irritatingly long wire dangling from the rear window because it neatly plugs into the side of the 622GW.

You interact with the Nextbase 622GW via a sharp, three-inch full-color rear touchscreen display that features small icons for navigating the various menu screens. These can be a little fiddly to locate, especially when you’re driving (not advised), while the touchscreen requires obvious digit swipes before it recognizes the command. 

Alternatively, there’s the option to link Amazon Alexa voice control to the 622GW via the accompanying MyNextbase Connect app, which is available for both iOS and Android devices. Once the two pieces of software are linked, you can simply say, “Alexa, ask my dash cam to take a picture” and the camera will oblige. It generally works well, although if you’re in a noisy vehicle Alexa can have trouble recognizing commands. 

Nextbase also now offers an upgrade to its coveted EmergencySOS feature in this camera, thanks to the addition of what3words geocoding. 

Emergency and breakdown services are increasingly looking to the innovative geocode system to provide help faster, as the technology can precisely pinpoint a location within three meters of a stricken vehicle, for example.

How does what3words work? If you find yourself in a remote area, this GPS alternative will let you precisely locate yourself, though you'll still need to make a phone call for help. For more serious incidents, there's also EmergencySOS, which can apparently work on very low data connection speeds (GPRS, or under 0.1Mbit/s).

Customers in all territories receive a year’s free trial of this EmergencySOS feature, but you’ll need to pay a subscription after that period.

Regardless, most of us carry a mobile phone these days, meaning EmergencySOS can be used with the accompanying app, and thanks to dual 2.4GHz and 5GHz Wi-Fi, cameras now tether to said app with fewer issues than previous Nextbase cams – although these issues haven’t been ironed out completely.

Previous generations of Nextbase dash cams have been massively frustrating to use, often failing to provide a stable connection to transfer still images and video between phone and camera, but things have improved. The set-up process is still a little fiddly and time-consuming, and the Wi-Fi connection between devices sometimes fails, but we managed to retrieve some imagery and footage after a few attempts.

It is, however, much simpler to plug the camera into a laptop or PC to access the footage, and playback is far slicker this way. We could imagine the app and its connection issues becoming frustrating to use if you were desperately trying to review footage directly after an incident, and this is something Nextbase, in our opinion, needs to address. 

But otherwise, the 622GW is an extremely easy camera to set up and use. Its 140-degree viewing angle isn’t the most extreme on the market, but it easily captures everything through the windscreen, and both its low-light and extreme weather recording modes, which use clever algorithms to improve the quality of the image, are great for capturing crisp footage in difficult situations.

New image stabilization technology also does its bit to ensure buttery smooth footage, cleverly soaking up bumps and vibrations from potholes or poor road surfaces. 

The improvements in sensor and processor technology means the resulting files are large, and Nextbase suggests investing in a 128GB U3 SD card, which isn’t supplied with the unit. These cost around $25 / £30 / AU$45, but opting for anything smaller will seriously restrict recording times.

Like most cameras on the market, the 622GW features a built-in G-Sensor, which will automatically save footage to the device if it detects a bump or crash. The sensitivity of this can be adjusted via the touchscreen display, but there’s also a handy Parking Mode that will automatically record footage if the G Sensor is activated, even when the camera isn’t drawing power.

The Nextbase 622GW is a clever little unit that now produces fantastic footage. Granted, the Nextbase app isn’t the easiest to use, but Alexa and what3words integration work extremely well, and have the potential to increase safety out on the road.
