Nextbase DUO HD – Full 1080p Front and Back Dual Lens DVR In-Car Dash Camera - 140° Viewing Angle – WiFi and GPS

Product Information

The Nextbase 522GW Dash Cam has all the benefits of the 422GW, plus a polarising filter that provides unbeatable picture quality to give you a superior dash cam experience. The polarising filter is an anti-glare upgrade to dramatically reduce windscreen reflections and record clearer images in direct sunlight. Cloud storage is available with a few dash cams. Uploading to the cloud in real time is a nice hedge against damage and theft—assuming the thief isn’t smart enough to kill the dash cam immediately. It’s handy for those managing fleets of vehicles, too, as incident videos are safely stashed online. The Nextbase 422GW brings all of the features of Alexa from your home into the car, along with voice control so you can focus on the road. Get driving directions, make calls, play music or ask Alexa to send the video straight to your phone, all hands free.

Plug your Dash Cam in. Ensure the cable is plugged directly into the dash cam and NOT via the mount. I try all the features: Buttons, display controls, apps.Aside from rear-view support and GPS, the most salient differences between the products are the interface controls and extra features, such as the lane departure and collision warnings that you get with some models. I try them…and I turn them off. In practice, they usually tell me I’m changing lanes, in heavy traffic, or have just been cut off. I know that. Additionally, the collision warnings generally come too late to do anything but distract you at exactly the wrong time. Nextbase iQ is the world’s first truly smart dash cam. With smart alerts to protect your car as the iQ continually monitors movement around the vehicle, expertly detecting potential threats. If the Nextbase IQ detects something unsual by your vehicle, it will let you know so you can intervene with voice or an alarm.

Stay sharp

WDR (wide dynamic range) is much like above, except it usually refers to only color and not contrast. A decently wide field of view:You’ll see cameras with as little as 90-degrees field of view, but you’ll catch more of what’s around you if you go for 120 to 140 degrees. Some cameras offer 160- to 180-degree lenses. Note that the wider the field of view, the more fish-eye distortion there is, and more processing is involved to compensate. If you want a basic dash camera then there are simpler, cheaper alternatives like excellent Nextbase 402G, but if you need record what is happening both in front and behind of your car then the Duo is ideal. It’s far more user-friendly and much less fiddly than setting up two separate cameras. I put each dash cam through several days’ and nights’ worth of driving,recording video and judging the image quality. All the dash cams I’ve reviewed in the last couple of years take good daytime video. However, night video is often plagued by murky shadows and headlight flare. That said, quality is improving rapidly with the introduction of new sensors. Take a close look at the night shots in each review. Nextbase have revolutionised the Dash Cam market with the 422GW, the world's first Dash Cam with Alexa and Nextbase Emergency SOS features.

Infrared lighting is important if you want to assure good captures ofnocturnal events inside the cabin of your vehicle. HDR(high dynamic range) isn’t necessary, but it does make for more detailed video because of better contrast. It also generally indicates richer color.

We’ll step you through what to think about when you’re shopping for a dash cam, from video capabilities, recording options, power connections, and more. Video capabilities Below are links to step by step instructions about how to update the firmware on your Nextbase Dash Cam. The Firmware Update Guides contain instructions for both Windows users as well as Mac users. Select the Dash Cam you have and wish to upgrade On the Dash Cam's screen you'll see a menu of 3 options. Please select 'Mass Storage' on the Dash Cam screen and then OK so that only that displays on the screen.

Dual-channel support: This is what you’ll need if you want to run both front and rear, or interior (cabin-view) cameras. Interior cameras are generally situated on the dash cam, but rear cameras are separate and require additional cabling. GPS: This feature could be the tipping point if you use your captured video to resolve a dispute. Watermarking the video is common, but when embedded into the video, GPS info is also immensely useful for mapping your travels. GPS will also automatically set the time in better cameras. Incident recording triggered by impact (G) sensors, or when in parking mode (see below), by motion detection. OBD-II 12-volt power (better): Outliers like the Owl and PureCam use the OBD-II connector for constant 12-volt power. OBD-II-to-USB power cables are now available separately (as an alternative to hardwiring kits that draw constant 12-volt power from the wiring harness).I recommend one with a USB Type-A port, which will accommodate any dash cam. Most of those with captive cables I’ve seen are mini-USB. The only downside is a long cable run, as the OBD-II port is usually next to the driver’s left knee, under the dash.

Continuous loop recording to minimize storage requirements. Video is recorded, then immediately overwritten at a specified interval unless saved. Video is saved (protected from overwriting) automatically when an incident is detected. Most dash cams will overwrite older recordings when they run out of space. Plug your Dash Cam in. Ensure the cable is plugged directly into the Dash Cam and NOT via the mount. Then the Dash Cam will be visible as a removable drive on your computer. If you go into My Computer (Windows) or Finder (Mac) you will be able to see the Dash Cam listed as a drive, usually called NEXTBASE. If the Dash Cam does not appear as a drive on your PC, please press the reset button on the underside of your Dash Cam and try all the USB ports on your computer.

On the dash cam's screen you'll see a menu of 3 options. Please select 'Mass Storage' on the Dash Cam screen and then OK so that only that displays on the screen.

Image quality that beats real life

Rearview 12-volt power (better): Another option that features a super-short cable run is powering your dash cam using your auto-dimming rearview mirror. You can find adapters for this at Dongar Technologies. If your car qualifies, this is by far your best option.
