Why every driver needs a dash cam
Dash cams have become an essential accessory for modern drivers. Whether you want to protect yourself against fraudulent insurance claims, capture scenic road trips, or simply keep an eye on your parked vehicle, a good dash cam offers peace of mind. The market is crowded with options ranging from budget-friendly 720p cameras to 4K HDR models with advanced AI features. To help you navigate this landscape, we spent weeks testing the most popular dash cams on the market, including units from Garmin, Nextbase, 70mai, Viofo, Thinkware, and BlackVue.
What we looked for in a dash cam
Our testing criteria focused on real-world usability. We assessed video quality in various lighting conditions (day, night, and low-light), field of view, ease of installation, app connectivity, GPS and speed logging, parking mode functionality, and overall build quality. We also considered value for money, ensuring our recommendations cover a range of budgets from under £50 to over £300.
Video quality and resolution
Resolution is the most obvious spec, but it's not the whole story. A 4K dash cam with poor dynamic range can be outperformed by a well-tuned 1080p model. We tested each camera on motorways, country lanes, and city streets during both day and night. The best performers consistently delivered clear number plates even under challenging glare or darkness.
Ease of use and installation
No one wants to spend hours wiring a dash cam. We prioritised models with simple suction mounts or adhesive pads and clear instructions. Cameras with integrated GPS and rear cameras that plug directly into the main unit scored higher for convenience. We also tested companion apps for live view, download, and settings adjustment.
The best dash cam overall: Garmin Dash Cam 67W
Garmin's Dash Cam 67W strikes an excellent balance between video quality, features, and price. It records in 1440p (QHD) at 60fps, offering smooth footage with excellent detail. Its wide 180-degree field of view captures three lanes of traffic effortlessly. The voice control feature lets you save clips or start recording hands-free. Parking surveillance is included with an optional OBD-II cable. The Garmin Drive app is intuitive and reliable. The only drawback is the lack of a rear camera option, though Garmin offers similar models with that capability.
Best value dash cam: 70mai A800S
70mai has rapidly gained a reputation for offering premium features at budget prices. The A800S records in 4K with HDR and includes a rear cam in the box (or sold separately). The Sony IMX415 sensor provides excellent low-light performance. The built-in GPS logs speed and location, and the 2-inch screen makes playback easy. The app connection is stable but slightly less polished than Garmin's. At roughly half the price of some competitors, it's an incredible bargain.
Best premium dash cam: Nextbase 622GW
Nextbase's flagship 622GW is a feature-packed powerhouse. It records in 4K at 30fps with image stabilisation, making it ideal for capturing smooth footage even on rough roads. The 'What3Words' integration is a unique safety feature that pinpoints your exact location in an emergency. The polarising filter reduces windscreen glare. The 622GW also supports Nextbase's range of rear and cabin cameras via a single connection. It's more expensive than most, but if you want the absolute best, this is it.
Best for parking mode: Thinkware U1000
Thinkware's U1000 is a premium 4K dash cam with exceptional parking mode. It uses radar and motion detection to record events while parked, drawing minimal power from the car battery. The built-in Wi-Fi and cloud connectivity allow remote viewing. The front camera captures stunning 4K footage, and the rear camera (included) records 2K. The app is comprehensive and the build quality is top-notch. It's the most expensive option here, but worth it for those who park on busy streets.
Best budget dash cam: Viofo A129 Pro Duo
Viofo's A129 Pro Duo offers 4K front and 1080p rear recording at a very competitive price. It uses capacitors instead of batteries, so it's more heat-resistant and long-lasting. The GPS mount is solid, and the video quality is impressive for the price. The menu system is a bit dated, but it's functional. Parking mode requires a hardwire kit (sold separately). For drivers on a strict budget who still want 4K and dual channel, this is the best choice.
Best for AI and driver assistance: Nextbase 322GW
Nextbase's 322GW is a mid-range champion that brings AI-powered driver assistance features. It offers forward collision warnings, lane departure warnings, and speed camera alerts. Recording is 1440p with excellent clarity. The magnetic mount makes it easy to remove for safe storage. It doesn't have 4K, but for most drivers, the quality is perfectly adequate. The 'My Nextbase' app is one of the best in the business.
How we tested
All dash cams were installed in identical vehicles (a 2022 Vauxhall Corsa) and driven along a standardised 20-mile route covering urban, rural, and motorway environments. We recorded both day and night footage. We also tested each camera's emergency recording by simulating a sudden stop and a minor impact. Parking mode was evaluated by leaving each camera running for 24 hours in a car park with moderate foot traffic. We scored each model on a 100-point scale where 50 points came from video quality, 20 from features, 15 from usability, and 15 from value.
Key features to consider
GPS and speed logging
Built-in GPS embeds your speed and location into the video metadata. This can be crucial for insurance claims or road-trip logging. All our recommended models have GPS, though some (like entry-level 70mai) do not include a GPS mount.
Parking mode
If you park on the street, parking mode is essential. Continuous recording drains your car battery. Look for motion-detection or time-lapse modes. Hardwire kits are usually required for 24/7 use.
Rear camera
Many incidents happen from behind. A dual-channel dash cam records front and rear simultaneously. Most of our picks offer add-on rear cameras, while Thinkware and Viofo include them in the box.
Cloud connectivity
Premium models let you view live footage from anywhere via a smartphone app. This is particularly useful for fleet owners or those who frequently park in unsafe areas.
Installation tips
Most dash cams come with a cigarette lighter adapter, but for a clean look, consider a hardwire kit. This connects to your fuse box and powers the camera even when the car is off. Many professional installers charge around £50-80 for hardwiring. For adhesive mounts, use the supplied alcohol wipe to clean the windscreen thoroughly.
Legal considerations
In the UK and most of Europe, dash cams are legal as long as they do not obstruct your view. Some countries have strict regulations about continuous recording in public areas. Always check local laws. In the UK, the Information Commissioner's Office (ICO) recommends that dash cams are used for personal purposes only and that footage is not published online without blurring faces and number plates.
Final recommendations
For the best all-round performance, the Garmin Dash Cam 67W is our top pick. If you want 4K on a budget, go for the 70mai A800S. For luxury features and the best parking mode, the Thinkware U1000 is unmatched. The Nextbase 622GW is the ultimate no-compromise option. And the Viofo A129 Pro Duo offers unbeatable value for dual-channel recording. Whichever you choose, a dash cam is a smart investment that could save you hundreds of pounds in insurance headaches.
