Yep even with the "bad" ultra or what ever they was named cards there was still hit and miss, the dashcam makers or at least the SOC makers probably are also to blame to some degree. Combine the 4K resolution with this mode, and it doesn’t come as a surprise that many car owners view the 622GW as the most reliable dash cam in harsh weather conditions. Drop this down to 1080p and it’s possible to review footage in slick 120fps slow motion – prefect for catching hit-and-run sneaks. If you have the dashcam fitted to a switchable fuse, ie when you turn the car off the camera is off as well, no problem.

When trying to make out finer details or capturing that all important number plate,4K recording quality is as good as it gets in a Dash Cam. p>National Tyre Service Ltd t/a National Tyre and Autocare is not authorised or regulated by the Financial Conduct Authority.The 622GW is compatible with any Nextbase Rear View Module, to offer-all around protection, whilst crucially maintaining front 4K image quality, with 1080p full HD rear recordings. 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. Opting for a renowned manufacturer is always a place to start, and that’s exactly the case with Nextbase. It uses a 140° ultra-wide viewing angle to capture the whole road behind, including the pavements on both sides. While it could be helpful in older cars, letting you control the camera and the audio playing on your phone using your voice, it’s not really necessary if you can run Android Auto or Apple CarPlay.

At 4K, it produced very steady footage – my car bonnet bouncing merrily over speedbumps while the video remained impressively level – but it became momentarily jumpy when turning 90° city corners.

For more serious incidents, there's also EmergencySOS, which can apparently work on very low data connection speeds (GPRS, or under 0. 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.
