Looking for a speed camera detector that fits neatly into everyday driving? The OOONO CO-DRIVER NO2 delivers camera and road hazard alerts without another screen on your dashboard.
You might spend hours choosing wheels, upgrading suspension or getting your driving position just right. An extra gadget has to earn its place in the cabin.
The OOONO CO-DRIVER NO2 has a straightforward pitch: useful information about the road ahead, delivered through sounds and an LED ring. There’s no display to find space for, and no monthly OOONO subscription to add to the running costs.
Whether your car is a modified daily or a weekend project, that makes it an upgrade worth a closer look.
How does this speed camera detector work?
The OOONO CO-DRIVER NO2 connects to your smartphone via Bluetooth and uses the OOONO app to deliver alerts from three complementary sources: an established camera database, known mobile camera zones and live reports from other drivers.
The foundation is OOONO’s maintained database of 145,000 camera locations worldwide. Its fixed-camera network spans more than 80 countries and includes over 9,000 fixed cameras in the UK alone. According to OOONO, 300 UK fixed cameras have been added during 2026!
Alongside that database, OOONO holds information on more than 14,000 UK mobile camera positions: places where police regularly operate camera vans. These zone alerts flag locations where enforcement commonly takes place; they do not mean a camera van is necessarily present at that moment bit highlight areas that might have a mobile camera van.
Live community reports add another layer of information. OOONO says its growing community now has five million users. Drivers using a CO-DRIVER NO1 or CO-DRIVER NO2 can report a mobile camera with one click, or a road hazard with two clicks, helping update other drivers about conditions ahead.
Although commonly described as a speed camera detector, the device uses this combination of stored camera locations, mobile camera zone data and live reports rather than scanning for radar or laser signals. Its alerts therefore draw on an established information network as well as updates from the community
Once you’ve completed setup and enabled the required phone settings, the device connects automatically as you start driving. Your paired phone and the app are still part of the system; this isn’t a standalone detector.
Useful even when you know the way
A journey to a show somewhere new is an obvious occasion to use navigation. Driving to work or heading across town? You probably already know every turn.
That was a key finding in our six-week review of the NO2 and NO2 PLUS. After more than 800 miles, we identified familiar journeys without navigation running as a particularly useful role for the device.
You don’t need to enter a destination to receive its warnings. That gives the NO2 a clear purpose for drivers who want alerts on everyday trips, including those in older cars without a modern infotainment system.
Knowing the route doesn’t mean knowing everything that might be on it today.
Set the alerts to suit you
Spend a few minutes exploring the app before your first drive.
In our review, we found some mobile camera zone notifications repetitive. Adjusting those settings while retaining the camera and hazard alerts he wanted made the device much easier to live with.
It’s a useful tip: take the time to choose your alerts rather than assuming the default setup will suit every journey.
The NO2 is there to support an attentive driver. It cannot guarantee a warning for every camera or hazard, and you still need to watch the road, signs and speed limits.
Keep your preferred navigation app
Adding the NO2 doesn’t mean changing your whole driving routine.
The OOONO app includes navigation and supports Apple CarPlay and Android Auto in suitably equipped cars. With the relevant warnings enabled and the NO2 connected, notifications can appear on the infotainment screen even while the OOONO app runs in the background.
Prefer your existing mapping app? You can keep using it while OOONO provides its alerts. We continued using Apple Maps during our test. It works great on more modern cars.
But where it really stands out is for enthusiasts with older cars without infotainment systems. Or those hardcore drivers who have stripped the interior of all unnecessary extra weight. In those situations, this little device can still provide the driver with much needed info about potential hazards without compromising the car’s interior.
Rechargeable, compact and subscription-free
The NO2 uses USB-C charging, and OOONO quotes around a month of battery life in normal use. Its magnetic dashboard mounts let you remove the device for charging.
At £69.99 on OOONO’s UK website at the time of writing, the NO2 includes access to the free app and its features without an OOONO subscription. You’ll still need a compatible smartphone and mobile data.
There’s plenty to be said for an accessory that fits around how you already use your car. For everyday camera and hazard alerts, without fitting another screen or entering a route for every trip, the NO2 makes a practical case for itself.
