Finally, the unit is compatible with Nextbase’s optional range of rear view and cabin camera modules. Nextbase 622GW dash cam review: Setup A Rear Window camera is also available, which attaches to the rear window via a magnetic mount and adhesive fixture (so it doesn't fall off when you slam the boot door). Despite needing an irritatingly long wire trailing through the car (we clip ours into the headlining), we'd opt for this one because it films directly out of the rear window, rather than the cabin too.

Recorded video can be viewed on the screen of the camera itself, on your smartphone via the Bluetooth and WiFi connections, or by slotting the microSD card into your computer. Nextbase 622GW vs 522GW: Price

How we tested

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. What’s the best on a budget: The 322GW is good value for money and has a decent selection of features for the price. Just don’t expect all the bells and whistles. 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 joy of all of these additions is that they’re interchange across the GW range. If, for example, you upgrade from a 322GW to a 622GW, you’ll still be able to use the axillary cameras, useful to know when it comes time to upgrade. In short: Super Slow Motion is a useful feature that's exclusive to the Nextbase 622GW. It enables you to play footage at a slower speed (120 frames per second at 1080p) to see precisely what occurred before and during an incident, as well as details like number plates. The feature is available on the MyNextbase Connect app on your smartphone orMyNextbase Player on a computer.

The adhesive mount isn't at all easy to remove from your windscreen, so if you plan to change it into different vehicles frequently, opt for the suction mount. Removing the mount also lets you access the removable battery, which is great for prolonging the life of the unit. div>
