Nextbase 622GW
7.2/10
The Nextbase 622GW is a front-only dash cam that records 4K, with a 3-inch touchscreen, built-in GPS and a magnetic mount. It suits drivers who want sharp footage from one camera and will buy their own memory card.
4K front video with a clear touchscreen for checking clips on the spot
Built-in GPS stamps speed and location on footage
Alexa voice control and a Nextbase app for downloading clips over Wi-Fi
Magnetic mount with a power cable that clips in and out quickly
Keep in mind
Front only, so a rear camera is a separate purchase
Parking mode needs a hardwire kit, sold separately
The battery is small and the unit can run warm in a hot car
The memory card is often not included

Why it sits behind the 70mai 4K T800E
The 70mai 4K T800E (7.5) beats the Nextbase 622GW (7.2): owners are about as happy with both, and it is the newer design.
About the Nextbase 622GW
The 622GW records 4K at 30fps, 1440p at 60fps or 1080p at 120fps through a 6-layer f/1.3 lens with a 140° view. The screen is a 3-inch HD IPS touchscreen. A built-in polarising filter has a rotating bezel to cut reflections off the windscreen. HDR and WDR handle mixed light, and there are Enhanced Night Mode and an Extreme Weather Mode aimed at fog.
GPS runs at 10Hz using GPS and GLONASS satellites, and Hotstart keeps the last satellite positions for up to two hours. Wi-Fi links the camera to a phone app for clips (iOS 10.3 and Android 5.1 or later). Alexa voice control is built in. Emergency SOS can alert the emergency services if the camera senses no movement after an impact, and what3words works offline and is accurate to about 3 metres. Intelligent Parking Mode uses motion sensing: it switches on after 5 minutes stationary or when the ignition goes off, saves a protected 30-second file on impact and stays on for 5 minutes.
In the box are the Click&Go PRO magnetic GPS mount with power connectors, a cable fitting tool, a spare 3M adhesive pad, a USB cable and a car power cable. Nextbase recommends a U3 microSD card for 4K, and sells 128GB and 256GB cards separately. A rear camera is a separate purchase; Car Magazine lists the 622GW as compatible with Nextbase's rear camera.
What owners report about the Nextbase 622GW
Owner feedback we found for this model is mostly from a few DashCamTalk forum threads, so it is thin and leans towards problems, as forums do. The praise that does appear is for the recordings and the image stabilisation.
The most repeated complaint is freezing. Several owners said firmware 12.6 caused random freezes, that a factory reset did not cure it, and that going back to firmware 12.4 steadied the camera. One owner reported later firmware removing menu options such as dual-resolution recording and auto power-off. Memory cards came up too: one owner's camera froze at start-up whatever card they tried, and other members pointed to Samsung EVO cards as a safe choice.
Heat splits owners. One owner with five units in different cars reports they get quite hot but do not overheat, including after a long drive. Another owner has been through several replacements for freezing and overheating. No two reports in the threads match exactly, so treat the fault rate as unknown.
Who the Nextbase 622GW suits
The 622GW suits drivers who want 4K footage, GPS data and a screen to check clips on the spot, from a unit that clips on and off its mount. It fits someone happy with front-only recording and fitting a memory card of their own.
Look elsewhere if you want rear coverage in one box: the 70mai 4K A810 Lite and Viofo A229 Pro 2CH come with a rear camera. Drivers who park in strong sun should note that one independent review, DashCamTalk, rates its 45°C maximum operating temperature as a weakness. For a cheaper Nextbase without 4K, the 322GW is the simpler choice, and the Garmin Dash Cam Mini 2 is the one to pick if you want a small camera that stays out of sight.
Questions about the Nextbase 622GW
What is the difference between the Nextbase 522GW and 622GW?
The 622GW records 4K at 30fps, while the 522GW records 1440p at 30fps. The 622GW also adds image stabilisation, what3words and Bluetooth 5.0 (the 522GW has 4.2), according to Car Magazine. Both have the same 3-inch screen, lens, GPS and mount.
Can the Nextbase 622GW record front and rear?
Only with a separate rear camera. The 622GW is a front camera, and Car Magazine lists it as compatible with Nextbase's rear camera.
Does the Nextbase 622GW record all the time?
It records while it has power, and loop recording overwrites the oldest footage when the card fills. The G-sensor protects clips from an impact. With Intelligent Parking Mode it switches on after 5 minutes stationary or when the ignition is off, and records a protected 30-second file if it senses an impact.
What are the common problems with the Nextbase 622GW?
Freezing is the main one owners report on DashCamTalk, with firmware 12.6 named by several and 12.4 reported as steadier. Some also mention it running hot, though one owner with five units says theirs do not overheat.
What memory card does the Nextbase 622GW need?
A U3 microSD card, which Nextbase recommends for 4K recording. It is not in the box, and Nextbase sells 128GB and 256GB U3 cards separately.
How long is the Nextbase 622GW warranty?
Nextbase gives 12 months. Its UK page words it as: "Electronic goods (such as dashcams): 12 months from and including the date of purchase." The page lists no registration condition.
Every score here comes from our ranking model; no editor sets the order. Too few review sites cover dash cams for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 24 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in October 2026.
