Nextbase 622GW 4K Dash Cam – UHD 2160p/30fps, 140° Wide Angle Lens – Wi-Fi, GPS, Bluetooth – Super Slow Motion (120 fps), Image Stabilisation, what3words, Night Vision

The video quality both day and night is fantastic. I have the 622GW running 4k30fps in the front and the rear window camera in the rear at 1080p30fps. Both are clear and sharp, especially the front one at 4k. Number plates and signs are easily read.The enhanced night vision mode which the camera automatically switches to when needed is brilliant. The polarised filter on the front is also a huge bonus.I'm impressed at how well it just works out of the box, parking mode is perhaps my only complaint with it saving a locked file every single time I get in the car as the g sensor is overly sensitive however with a 128gb card, you can just format it every month or week to stop the locked files filling up your card and I'd rather it too sensitive and not recording when someone hits my car gently enough to cause damage but not activate many other dashcams.The hardwire kit is a must for me, the battery of the camera has so far performed very well however with tit being constantly charged and discharged I can't see this being the case forever so I think it's worth the piece of mind to hardwire it to your car's battery.The camera takes good quality photos even at speed which is also nice, possibly a handy feature for some though I can't think of any situation I'd use it as I'd prefer a video or would just screenshot the video for a still image.The mic is good, perhaps a little quieter than some cameras but it's clear and road noise isn't bad at all, it picked up my horn, voice and other horns and such within reasonable distance of the car. Remember you are in a sound insulated box of metal on wheels so don't expect miracles.The speed and GPS readings built into the camera is brilliant. They overly nicely into the bottom of videos alongside your number plate and camera model.I've not used the app much but it's worked flawlessly when I have. Downloading videos via WiFi was very quick and easy as was live view mode and watching back videos showing telemetry and map location data.The camera has never crashed except when I removed the SD card without stopping the camera recording which is honestly expected and a simple reboot instantly fixed it. I was also pleased to find the only video that was corrupt was the one recording at the time which is good as other dashcams I've had have corrupted every single file on the card when doing this causing me to lose a lot of footage, fortunately nothing I needed.The rear camera also doesn't reduce the max resolution of the front camera which is great to see as many do this and it's very frustrating.I'd strongly recommend the camera with the rear camera if you want great quality footage. The steep price is worth it. The camera feels durable, is well thought through, built well, works well and is very user friendly.

Excellent piece of kit, which is easy to fit. I used the hard wire kit and followed an online you tube . Easy peasy.

------------------------------Original review:-------------------------------I'm giving this camera 8 out of 10 as it's build quality is excellent, it has a great clear touch screen the audio is ok and (in my case) pairing the Alexa app on my phone and my car radio (via Bluetooth) makes it quite useful as I can find out if there are any problems on the roads I will be traveling on, also another good feature is the 'What3Words' app for pinpointing your location, I know this might be a gimmick to sell the product but for me I do use it as I do a lot of Walking/hiking and if I park somewhere I haven't been before one click and I can find that place again to within 3 meters.The only thing I'm NOT happy about is, it doesn't matter what resolution I set the camera to, it doesn't show number plates at night unless your directly behind the vehicle, if your on a motorway any vehicle either side of you (if you was in the middle lane) is not legible, this maybe down to my settings as I'm still playing around with things, if I get it sorted I'll update this review.All in all I'm very happy with it.------------------------------Update:-------------------------------The spec sheet says 1080p@120 fps, this was NOT possible with the camera I purchased, not a big deal but if you're told it can do something that it can't then it's a false claim, I sent it back after about 5-6 weeks as the screen kept freezing randomly for no apparant reason, this happened about 8 times while I had it and you don't really notice when it happens as obviously you're watching the road not the camera, I had to remove the power cable and let the battery run flat as that was the only way of turning it off (pressing the button or the screen did nothing), I did notice a reset button when packing it up for return but I don't know if that would have turned it off & on again or reset all the settings back to default even so the button is that small and discrete you would need something like a paperclip to press it so not practical or safe to do whilst driving.The quality of the image and sound are second to non but as other reviewers have mentioned the camera freezes and I just thought it maybe a bad batch so took the risk, for now I'm dash camless but if they fix the problem I maybe persuaded to give it another chance.--------------------------------------------------------------------

Bought this to replace my 222x dashcam. Very clear image and useful GPS feature showing speed and location. It also fits onto the suction mount I used for my 222x dashcam, as I didn't want to permanently attach it to the windscreen. Easy enough to use.
