I sent it to Nextbase (after they first sent out a replacement cable which didn’t help) the problem turned out to be a broken connection on the usb connector. The NEXTBASE Video Recording 3 inch Dash Cam is a premium quality camera with 1440p quality and full night vision capabilities. We do our best to maintain our position as the market leader, and we continue to develop and manufacture the best multimedia system for rear-seat passengers as well as Dash Cam for drivers. You will need a separate power supply and SD card as it will not connect to your 512GW, but can be used as a Camera facing rearwards. There’s a time-lapse option with durations of three minutes or two hours between frames, which are rather strange choices.

However, unlike DDPai’s app where you can download a video while it plays on screen – you can stop once you’ve captured everything you need – you have to wait for a full three-minute clip to transfer. The rear dash cam, which turns the 512GW into a dual dash cam, is also a useful tool in the event of an accident because you can check the footage to see if they were driving too close or were distracted (like using their phone while driving). I also use the 512 in another vehicle, although not the rear camera that stays permanently in my vehicle. You can then view footage using the Nextbase Replay 3 software, available for both 32-bit and 64-bit Windows as well as for macOS.The lens isn’t the best: there’s a fair amount of barrel distortion, but quality is the best we’ve seen from any rear camera. Fault:- when first power up after connecting 512 to rear cam then inserting 512 into windscreen mount is the PiP of rear view is just an outline. Works in conjunction with your front facing Nextbase 512GW Dash Cam, with both cams recording at full 1080p HD at 30 fps.

The disadvantage is that it doesn’t allow for quite as much movement and so the angle shown in the video and images below is the lowest it’s possible to tilt the lens. The healthy data rate and Full HD resolution provide footage that’s faithful in colour and relatively devoid of artefacts. Please check that your Camviewer app is on the latest version available and that your phone has Wi-Fi turned on. It’s difficult to hide under rubber door and boot seals, and is also hard to manipulate around corners. all in all an ok unit that helps reduce the clutter in the windscreen - hopefully the firmware update will sort the freeze and the speed issue.By connecting the GWRC (rear cam), you get front and rear footage saved onto one SD card, both recording decent 1080P quality footage. DEGREE WIDE ANGLE: The 512GW offers 1440p HD recording capabilities at 30 frames per second, and 1080P recordings at 60fps through a 6-element glass lens to ensure a moment is not missed on the road. The front cam is attached via a suction mount, while the rear camera is attached the rear windscreen via adhesive mount - which means it shouldn't ever fall off even if you slam your boot door hard. Please turn Parking Mode off and turn Screen Saver off as these could interfere with the test results.
