How to buy the best dash cam
By Louise Muyanja
A decent dash cam or dashboard camera is capable of producing high-quality video footage to help prove what happened in the case of a crash, or protect you from false claims.
But not all dash cams on the market are worth your money.
Our in-depth tests of dash cams reveal that there are big differences in quality between different models. Below, we explain what you need to know to choose the best dash cam for you and your budget.

Dash cams range in price from basic £20 models to feature-laden dash cam systems for anything up to £400.
Price doesn't predict quality, however. We've found models from both ends of the spectrum have failed to impress in our thorough lab and road tests.
The most important aspect of a dash cam is the quality of its footage. If the image quality isn't good enough, you might not be able to use your footage after an accident to prove you're not to blame.
All dash cams support at least HD resolution (1,280 x 720 pixels) but it's most common for dash cams to record in Full HD (1,920 x 1,080 pixels). Some can record up to 4K (3,840 x 2,160 pixels).
A higher resolution doesn't guarantee better quality - we've uncovered higher resolution dash cams that produce dire footage. We've also found dash cams at 1080p that are clear and detailed.

What makes a good dash cam?
The most important aspect of a dash cam is the quality of the footage it records. If image quality isn’t high enough, you might not be able to use your footage in the case of an accident to prove you’re not to blame.
A higher resolution will generally mean a better quality of footage, but it doesn't guarantee it - we've uncovered higher resolution dash cams that produce dire footage.
By contrast, we've also found dash cams at 1080p that are still clear and detailed.
How easy a dash cam is to use is also very important. That includes how easy they are to fit, set up using the provided instructions and remove from the mount.
The best dash cams we've tested are easy to install into the car and just as easy to remove when you leave your car.
Although you shouldn't be swayed by the bells and whistles, it's also important to consider what features you're getting for your money.
Features like GPS tracking (to show your exact location in footage) and wi-fi (to wirelessly transfer footage to your phone or tablet) aren't essential, but would be very useful.
That said, no features should be the deciding factor. We've tested Don't Buy dash cams with GPS and wi-fi.
A single forward facing dashboard camera records the road ahead. A front and rear dash cam is a multiple-lens system that offers both forward facing and rear windscreen cameras.
Here are the pros and cons of both types:
Forward facing dash cam
Forward facing dash cams are the most basic and common type of dash cam. These record from a single camera lens and are mounted onto the windscreen to record the road ahead.
- Pros: They're the most common type of dash cam, so it’s easy to find one to match your budget.
- Cons: May miss events behind the car.
Front and rear dash cams
These dash cams can record from more than one camera at the same time. Typically, the forward facing lens is mounted to the windscreen and a secondary lens is mounted to the rear windscreen, to record the road behind. With some dash cams, the rear lens is attached to the forward facing one, meaning it records the rear of your car through the cabin and out of the rear windscreen.
- Pros: You have the peace of mind of footage being recorded on both sides of your car.
- Cons: More fiddly to set up – you may need to hardwire the devices in, which could require professional installation. It's also likely to be more expensive than a single-lens dash cam.

- GPS - allows you to pinpoint your exact location at the time of the crash. It will also show the route you travelled, and your speed. This could be useful for building up a picture of exactly what happened in a crash.
- G-force sensors - automatically saves moments of high G-force, generally during a collision. This means footage - which is recorded on a loop - will be protected from being overwritten.
- Parking mode - your dashboard camera will automatically start recording if it detects a collision of impact while you're parked. Useful for finding out who bumped your car in a busy car park.

Other dash cam features to consider
SD memory card
All dash cams use a memory card to store recorded images and video footage. All the dash cams that we have tested use ‘loop recording’, meaning that when they run out of space on the memory card they rewrite over the oldest footage.
Some models come equipped with an SD card, but this is worth checking. If you need to purchase an SD card separately, we recommended you use class 6 or above. This ensures that it performs at a high enough standard to be reliable for use in your dash cam.
Dash cams that come with an app
Dash cams that come with accompanying apps for your smartphone or tablet will enable you to save your footage onto your phone.
If a dash cam doesn't come with an app, you can still save your footage by transferring it to your computer.
Transferring the footage means you can protect your valuable recordings from being overwritten. So even if you don't do this regularly, make sure you do it after an incident.
All dash cams come with a power cord that plugs in to the cigarette lighter. These range from around 1.4m up to 4.9m.
Choose a model with a longer cable if you want to route the cable around the windscreen and down the car’s front pillars. This means you can plug it into the power socket without having cables dangling down from the windscreen.
You may prefer to have your dash cam hardwired in, so will need to consider whether you want it installed professionally.
Wi-fi dash cams let you transmit footage wirelessly from the camera to your device - so no need to remove it and take it indoors.
You'll also be able to view footage from the dash cam in real time via the wireless connection.
Some insurers will offer you a discount if you have a dash cam. To find out more, see our guide to dash cam insurance savings.
