Nextbase iQ
5.7/10
The Nextbase iQ is a connected dash cam with a front camera, a cabin camera and a built-in 4G connection. It suits drivers who want parking alerts and remote access, and will pay for a plan to get them.

About the Nextbase iQ
The iQ comes in 1K, 2K and 4K versions. The 4K model records the road ahead at 2160p with a 140° view, and its cabin camera records at 1440p with a 180° view. Infrared night vision covers the cabin after dark. Nextbase also lists image stabilisation and a 7-layer lens.
It is a single unit that sits behind the rear-view mirror. Power comes from the car's OBD port, with a hardwire cable and fuse taps as the alternative. Setup runs through the iQ app, which guides the fitting. Expert Reviews puts the mount and camera at about 17cm top to bottom, and notes that the antennae and large mount can make it awkward to position near the top of the windscreen.
Most of the clever features depend on the 4G connection. Smart Sense Parking alerts your phone to movement, loitering and impacts while the car is parked. Live View shows the camera feed and lets you speak through it. Witness Mode streams to a trusted contact on a voice command. Emergency SOS shares your location and medical details if you are unresponsive after a crash. Guardian Mode alerts you when speed, G-force or location limits are passed.
The unit works without a subscription, but only for the basics: the app, voice control and text notifications. Live View, parking alerts and Witness Mode need the Protect plan, and Emergency SOS needs Protect Plus. The 4K camera ships with a 64GB U3 microSD card, an OBD power cable, a hardwire cable with fuse taps and a fitting tool. The 2K iQ Rear Cam is a separate purchase and works with every iQ model.
What owners report about the Nextbase iQ
Owner feedback we found for this exact model is thin, and it is concentrated in forum threads. Those who mention the front camera say it works well, and one owner said the iQ was working great until a rear camera was added.
The rear camera is where the complaints sit. In DashCamTalk threads, owners describe the app failing to detect the rear unit, setup timing out, and the connection dropping out after it was added. One owner updated the firmware and the app as Nextbase advised and still had dropouts, so they disconnected the rear camera. Another reported slower footage downloads once it was fitted. Nextbase has a support article on reconnecting a rear camera that is not found, which points to the cabling and a firmware update.
These are individual forum reports, not a measured failure rate, and firmware may have changed things since.
Who the Nextbase iQ suits
The iQ suits drivers who park on the street or leave the car for long periods and want a phone alert if someone knocks it. It also suits those who want SOS and remote viewing from a known UK brand, and who accept an ongoing plan. The front and cabin cameras together make sense for taxi, hire or family-car use.
Look elsewhere if you want a one-off purchase with no running costs: the Nextbase 622GW is a 4K front camera with no plan needed. If you want a front and rear pair from the start, the 70mai 4K A810 Lite or Viofo A229 Pro 2CH include the rear camera. For something small and unobtrusive, the Garmin Dash Cam Mini 2 is far less bulky. Cars that sit unused for more than about six days may struggle with the constant power draw, according to Expert Reviews.
Questions about the Nextbase iQ
Is the Nextbase iQ worth it?
It is if you want parking alerts, live viewing and SOS, because those need the plan. Expert Reviews says the unit is not worth having without a subscription apart from its text alerts. If you only want to record journeys, a cheaper dash cam does that.
Does the Nextbase iQ need a subscription?
Not for basic recording. The free Solo tier gives you the app, voice control and real-time text notifications. Live View, Smart Sense Parking, Witness Mode and 4G data need Protect, and Emergency SOS needs Protect Plus.
Is the Nextbase iQ wireless?
Partly. It connects over Wi-Fi and a built-in 4G connection, but it is not battery powered. It draws power from the car's OBD port or a hardwire kit.
Does the Nextbase iQ come with a rear camera?
No. The iQ Rear Cam is a separate 2K camera that works with every iQ model. Some owners on DashCamTalk report it not connecting or dropping out.
Can the Nextbase iQ drain my car battery?
It can in a car that is rarely driven. Expert Reviews says a failsafe shuts the unit down before core vehicle functions are affected. Nextbase's FAQ, as quoted there, says problems mainly arise if the car sits idle for more than six days.
Every score here comes from our ranking model; no editor sets the order. Too few review sites cover dash cams for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 24 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in October 2026.
