Types of dash cam

There are two types of dash cam: forward-facing or front-and-rear. A forward-facing dash cam records the road ahead.

A front-and-rear dash cam is a multiple-camera system that offers both forward-facing and rear-windscreen cameras. Some manufacturers, such as Nextbase, offer rear cameras separately, so you can buy the rear camera later and link it to your existing front camera.

Although all rear dash cams have the same objective of recording what's behind you, you will get a very different rear view depending on which you choose. The three main types are:

• Rear-window dash cam – these record the road behind your car. These devices are separate from the front camera; you install them directly on the rear window to get a clear, uninterrupted view of the road behind.  
• Rear-view camera – as with rear-window dash cams, these record the road and surrounding area behind your car. This type comes as part of the main device that sits on your windscreen and records the front view, which means it records the road behind at a greater distance, through the car and out of the rear window. 
• Cabin camera –  these rear cameras aren’t as commonly found as the other two types. They’re designed to capture what’s going on inside your car. They’ll mainly show the interior, but may also capture some of your car’s surroundings through the windows and rear windscreen. They're usually more popular with professional drivers, such as taxi drivers.

How much does a good dash cam cost?

Dash cams range in price from basic £25 models to feature-laden dash cam systems costing upwards of £500. 

Price doesn't predict quality, though. We've found models from both ends of the spectrum that failed to impress in our lab and road tests. 

And while bells and whistles may be nice to have, the most important aspect of a dash cam is footage quality.

Cheaper models typically record footage at a lower resolution, either HD (1,280 x 720p) or Full HD (1,920 x 1,080p), and tend to skip the fancy features you'll find on premium models. 

However, you can still expect to get the basics such as audio recording and the ability to take still photos.

If you want to get a middle-range model, they'll usually record in Full HD, and have extra features such as parking mode, GPS and wi-fi connectivity.

Alternatively, premium dash cams commonly record in 4K (3,840 x 2160p). You can also get more advanced extras such as voice recognition at this price.

Best dash cam features to look for

Here are the main dash cam features to check for. 

• Parking mode –  your dashboard camera will automatically start recording if it detects a collision or impact while you're parked. Useful for finding out who bumped your car in a busy car park.
• Footage quality – if the footage isn’t good, you may as well not have a dash cam. Our lab tests evaluate the footage of dash cams during the day and night, ensuring crucial information, such as number plates, is clear.
• GPS tracking – most dash cams have GPS built-in, meaning they'll record not only the location of your vehicle but also the speed and direction you're travelling (useful when submitting footage after an accident).
• Wi-fi – wi-fi lets you transmit footage wirelessly from the camera to your phone, so no need to remove the camera or its memory card to download footage. Some dash cams also allow you to view footage from the dash cam in real time via the wireless connection.
• Voice controls – this lets you say commands such as 'save video' or 'take a picture', without taking your focus off the road.

Don't assume lots of features results in a good dash cam, though. We've found Don't Buy dash cams that have both GPS and wi-fi, for example.

Does having a dash cam lower your insurance?

Insurers sometimes give discounts or consider dash cams when they assess how safe you are behind the wheel, which could mean paying less for insurance.

If you have a dash cam, let your insurance company know to check if you qualify for a discount.

But here’s the real deal - having a dash cam can be a game-changer if there’s an accident. It can prove you weren’t responsible, saving you money and saving your no-claims discount—a reduction on your insurance cost for having a clean claims history.

Which dash cam brands offer the best software and security support policies?

Software and security support are important considerations when buying a dash cam, dictating how long the brand aims to update the device with new features and security patches, to guard against emerging threats.

• Nextbase says it will provide updates for up to five years from after a product is last sold. 
• Thinkware says it will provide security updates 'throughout the product life', which it says is 'often six years'. 
• Mio was quite vague when we approached it last year, stating 'two to three years' of support. This year it didn't respond.
• Garmin, one of the biggest brands, said in 2022 it would only guarantee a minimum of two years from launch. This year it didn't respond.
