Best Prices Today: Nextbase iQ 4K dash cam

Nextbase has spent years developing the iQ, and its launch was pushed back several times. It’s now on sale at last, albeit without a couple of key features that the company has shouted hyped up over the past 18 months or so.

However, as hard a concept as it is to sell to consumers, the iQ is meant to be an ever-evolving platform that will get new features over time.

The only problem with that approach is that this isn’t a cheap gadget and, as with so many internet-connected ones, you need to pay a subscription to use the features.. even if they’re not yet there.

There are three models in the range: 1K, 2K and 4K, starting at £349 / $499 and rising to £449 / $699. The resolutions refer to the forward-facing camera, but there’s also a cabin-facing camera, and an optional rear camera for £149 / $199 which wasn’t quite on sale at the time of writing but should be from 14 November.

Nextbase sent the 4K model for review.

Features & design

• Easy to install
• Embedded SIM
• 64GB microSD card included

The iQ has been designed from the ground up, and that’s very obvious if you’ve seen or owned any of the company’s previous dash cams.

It has a fairly chunky base which attaches to your windscreen and has a fabric speaker cover much like a smart speaker. The LED ring only adds to that similarity.

The two cameras are mounted in a pendant-style unit that points downwards into the car. In your hand, it seems like it will be large and obtrusive, but when installed it really isn’t.

The design is necessary for the camera to get a good view of the interior and passengers. The cabin camera also has infrared LEDs so you can still see what’s going on at night when the cabin is dark.

Nextbase includes a 64GB microSD card which you shouldn’t ever need to remove from the iQ, but you can upgrade it to 256GB if you want to.

It’s used to record video like a traditional dash cam, but the iQ does way more than that, and I’ll get to that in a second.

Installing the iQ in your car is simple because Nextbase includes a clever power cable that plugs into your car’s OBD II port. You might have to Google its location if you’re not familiar, but all cars since around 1996 have one.

The connector is as slim as possible so should fit behind a cover, but the cable exits from the side which proved to be a problem in my wife’s 2013 Vauxhall Corsa which has a recessed OBD II port, making it impossible to plug it in. It wasn’t an issue in my Ford Focus though.

There is a solution in the box though: fuse taps that you can connect to the appropriate fuse in your car’s interior fuse box. The only disadvantage is that you need to know which fuse to use, and to find a handy bolt that connects to the car’s chassis to which to attach the negative wire.

The only gotcha is that the adhesive mount needs to be stuck to your windscreen in a precise orientation. Rotate it slightly left or right and the iQ won’t be vertical, so it’s a good idea to offer it up with the camera attached to the mount.

The power and rear camera cable use proprietary connectors, like squared-off USB-C, which attach neatly into the rear of the iQ.

As part of the process you need to install the Nextbase iQ app on your phone and create an account. The app will walk you through the hardware installation and ask if you have a rear camera. The iQ’s data connection should activate and you’ll have to scan a tiny QR code on the iQ’s screen.

This is where the process fell down for me, as the code seemed far too bright in the preview and any slight movement of the phone caused it to blur. Using the tips provided in the app, it did eventually scan after I double-tapped the preview to turn on my phone’s rear LED flashlight and slowly move the phone closer to and away from the screen until it scanned.

If you manage to jump this particular hurdle, the iQ will download the latest firmware and restart, at which point you can see the live camera view and adjust the angle to get the best view of the road ahead (and behind if you have the rear cam).

The embedded SIM means the iQ is always connected to the internet. It isn’t the first dash cam to do this, but it’s certainly the best-executed

Live view & alerts

Getting back to features, the embedded SIM means the iQ is always connected to the internet. It isn’t the first dash cam to do this, but it’s certainly the best-executed.

Via the Nextbase iQ app, which has clearly been inspired by Ring’s, and with the appropriate subscription in place, you can watch the live views from each camera and see on a map exactly where the car is along with the What3Words location.

Of course, any security camera worth its salt will tell you when something important is happening and the iQ is good at it. Using a variety of sensors, including radar, it will send you notifications of “Parking events”, which could be someone reversing into your car in a car park or a person loitering with intent. I found it would also notify me when I parked up and got out of the car, and again when I returned.

You can watch the recorded event, which shows all camera views on the same screen, and a useful red highlight on the playback bar means you can skip straight to where the action happened.

Although these events are automatically uploaded to the cloud (where they’re safe for 30 days if you subscribe to Protect or 180 days with Protect Plus) you can download them to your phone and then share them or, better still, send someone a link and unique code to see the video online.

These aren’t the original full-resolution versions, though. They’re standard-def 848×480-pixel clips.

In the SmartSense settings in the app you can adjust how far away in each quadrant to monitor. There’s also a setting for the ‘activation voltage’ at which SmartSense should kick in.

This is different from the ‘Low power cut-off’ setting which shuts off the iQ if your car battery drops below a set voltage in order to ensure it doesn’t drain so much you can’t start the engine.

Emergency SOS

One of the other main safety features is Emergency SOS, something previous Nextbase dash cams have offered. You’ll need a Protect Plus subscription to enable it.

When set up, the iQ will monitor for a “severe crash” and when it detects one it will automatically send an SOS to emergency services with your exact location and – if you’ve provided it – your medical data.

You’ll receive a call back from those services but if you’re unable to answer, an ambulance will be dispatched to your location automatically.

Voice commands

In some of Nextbase’s 2-series dash cams you could use Amazon Alexa. With the iQ, Nextbase has custom-built its own voice commands. This means you can say “Hey dash cam, enable Witness Mode” and it will record and upload whatever’s going on – and live stream to up to two emergency contacts. Once the event is over you can say “Hey dash cam, stop Witness Mode” or “We’re safe now”.

You can also say a variety of other things prefixed by “Hey dash cam” such as:

• Turn the microphone on
• Turn the microphone off
• Start recording
• Stop recording
• Lock this file
• Turn the cabin camera off
• Turn the cabin camera on

For each, your command is processed locally and there are many variations of each command so you don’t have to remember the exact phrase. They all worked reliably when I tried them while driving.

Fortunately, turning the mic off only means audio isn’t recorded – it remains on to listen for your next command.

Currently, there’s no spoken feedback: everything is communicated using alert tones and a small LCD display which shows icons – it isn’t used for showing video.

Missing features

As mentioned, a couple of features are not available at launch. One is Guardian Mode. This is designed partly for parents with young drivers who want to keep tabs on them. When it’s added, you’ll be able to set speed and location limits, and get notifications when the car exceeds or leaves them.

This is also useful if you leave the car at a garage for repair, or with a valet.

A talk-back feature will allow you to communicate with whoever is in the car, too.

The second headline feature that isn’t available is Roadwatch AI. This uses a combination of computer vision and radar to identify other road users, their speed and trajectory.

This data can then be used alongside the video itself to help prove what happened if there is, for example, a collision.

As the iQ records video using H.265, you can’t use Nextbase’s current desktop viewer as it supports only H.264, so there was no way of getting at any of the recorded meta data at the time of review.

Performance & quality

As you’d expect at these prices, quality is good, although perhaps not as good as might hope for. Resolution depends upon the model you buy. The 1K has 1080p front and cabin cameras, but the interior is recorded at 1440p if you buy the 2K or 4K models.

The rear camera records at 1440p and can be connected to any of the three models.

I tested the 4K and the quality from the main front-facing camera is generally respectable, and a step up from Nextbase’s 622. There’s lots of detail which means you can read registration plates of other vehicles, whether they’re parked or driving.

There are quite a few exceptions to this, though. At night or if the weather is bad, details can be obscured by rain on your windows, or because your car’s headlights are reflecting off number plates.

The wide field of view means cars also have to be quite close by, otherwise their plates are simply too small to see. Usually, though, you only care about these details if another car hits yours – meaning it will be very close.

As there’s no HDR, dynamic range is somewhat limited and this can cause over- or underexposure when the sun is in the frame.

It’s surprising there’s no polariser for the front or rear cameras, neither built-in nor optional. There are just two video quality settings in the app, too, one being to disable audio recording. That leaves only exposure, which can be set separately for each camera.

Here are some examples of snapshots from day and night recording from all three cameras.

In the app, you’ll find recordings split into two sections: Events and Library.

Events is the important stuff, such as impacts, motion detected while parked and manual recordings where you’ve locked a file by saying the command, or pressing the button on the underside of the iQ. All are uploaded to the cloud automatically if you have a Protect Plus subscription.

Library is where you’ll see a complete timeline of all the events along with the regular continuous clips recorded while driving along. You can download any of these clips within the app as long as the iQ has power and a mobile data signal – and you have a Protect or Protect Plus subscription.

Whenever you download something, you can pick which of the camera feeds to include: you don’t have to download all of them.

It can take a while for the iQ to wake up and start streaming video if it’s in low-power mode, but the app does a great job of telling you what it’s doing rather than merely showing a spinning circle.

Although there’s built-in Wi-Fi, Nextbase says it’s working on a direct Wi-Fi link and expects local downloading to be possible some 4-6 weeks after launch.

You can of course take out the microSD card and pop it into a card reader on your laptop or PC but Nextbase has added an HD download option in the app. Unfortunately, this is only for videos in the…
