5 things you really need to know about dash cams

We’ve busted five of the biggest dash cam myths, including whether or not your dash cam is illegal

When you’re buying a dash cam, you’ll quickly realise there’s a lot of marketing bumf and common misconceptions you’ll need to wade through. Do you really need a high-resolution model? Are dash cams illegal? We’ve dug into common dash cam myths to set the record straight.

Dash cams can help you out if you’re involved in an accident and manage to get a recording of the perpetrator, but did you know that a dash cam can save you money? And that you can actually buy a cheaper model that records higher-quality footage than a pricey one?

Read on to find out more.


We’ll help you pick the right model for your budget – see our best dash cams.


1. You don’t need to buy a higher-resolution dash cam

Manufacturers are always keen to boast that their dash cams record the best footage. So it’s not uncommon to see fancy resolutions like ‘4K’ and ‘Quad HD’ plastered all over marketing material.

But our independent tests have revealed that a dash cam doesn’t have to record in the highest video quality, such as 4K, to capture high-quality footage during the day and at night.

It is true that the higher the recording resolution, the better the footage. However, dash cams with the highest recording resolution are typically the most expensive. So if you’re on a budget, you could be put off the idea of buying one altogether.

More than half of the Best Buy dash cams we’ve tested record in Full HD. So, rest assured that you can get a great model without needing to splash out on the highest resolution.

2. Good dash cams aren’t always expensive

You don’t have to dig too deep into your pocket in order to buy a great dash cam. We’ve recently tested a dash cam for under £50 that impressed us enough to make it into our top five dash cams for 2019.

We’ve also tested a dash cam that cost over £200, but we wouldn’t recommend it. So don’t assume that paying more will guarantee you a great model. Instead, use the results of our lab and road tests to choose the right model at a price you want to pay.

The most premium models typically come with more advanced features, like speed camera alerts and voice activation software.

If these features don’t interest you, you can buy an affordable dash cam that does the most important job of recording high-quality footage, for almost half the price.

3. A dash cam can save you money

Dash cams are typically seen as your second pair of eyes if you’re involved in an accident, but that’s not the only thing that they’re useful for. Some car insurance companies reward their customers for owning a dash cam by offering discounts on your premium.

Some of the most well-known insurers have sizeable offers, so you can save money on your car insurance just by owning a dash cam.  Axa and Swiftcover, for instance, give up to a 10% discount to customers who install dash cams in their vehicles.

4. Dash cams are illegal in some countries

Outside the UK, there are a number of countries where dash cam usage is restricted or even prohibited. In Austria and Portugal, dash cams are banned entirely. Other European countries, like Belgium, France and Germany, place restrictions on them for anything outside of private use.

If you’re driving your car abroad, it’s important to check the rules of the country you’re visiting before you travel with a dash cam.

Dash cams are legal within the UK, but there are strict rules about how you can use them.

Dash cams must be installed correctly to ensure that they don’t obstruct your vision while you’re driving. If it’s positioned incorrectly, you could face a fine and your footage may be rendered inadmissible in court.

5. Not all dash cams are equal

Dash cams can all appear to be the same, given that they all record the road while you drive. But models can differ hugely in their footage quality and the features and functionality they offer.

We’ve tested some dash cams that are incapable of producing clear footage, even in the daytime. The very best ones produce clear recordings, even at night with the glare of headlights and street lights around.

But footage isn’t all that sets the best dash cams apart.

Common features like G-force sensors (which automatically activate the camera and saves footage at moments of high impact) and parking mode (which automatically starts recording if a collision occurs while you’re parked) can now be found on most dash cams.

But advanced features, like Bluetooth and speed camera alerts, are typically found on premium models. It’s worth noting that premium features don’t always equal premium footage quality.
