Dash cams, also known as car DVRs or dashboard cameras, record while you're driving so you have evidence of what happened in the event of an accident. Dash cam footage is now generally accepted by insurers as evidence of fault in an accident and it’s also admissible in court. The best dash cam is the Asus Reco Classic but we've also tested 10 of the best alternative car dash cams for you to choose between. Also see: How much is my car worth?

You can jump straight to the reviews.

Using a dash cam to record your driving can reduce your insurance policy by around 10 or 15 percent. For example, Adrian Flux offers a 15 percent discount if you have one of the cameras listed on its website. AXA and Swiftcover also offer discounts. Below is a great example of a video caught on a dash cam that proved the driver wasn't at fault. Without video evidence, it would have been his word against the van driver's.

Watch out for a clause in your policy which says that an insurer can demand footage from your journey in the event of a claim, as it may show you are at fault. Certain cameras record the speed at which you’re travelling, embedding it in the video, and will show if you were speeding. We recommend turning off the speed recording in your camera's settings.

Here’s what to look out for so you can spend your money wisely. See all camera reviews.

Best dash cam: Buying advice

Prices range from around £20 to £200, so there's a model affordable for everyone. However, those cheap models tend to lack features and won't typically record great-quality footage.

Best dash cam: GPS

GPS allows the camera to record your route as well as your speed. The GPS data is synched up with the video clips when played back in special software so you can watch the footage and see your location on a map. Some GPS receivers are external and have a long wire so they can be mounted out of sight. Others are part of the suction mount, while yet others are inside the camera itself. Also see: CarPlay and Android Auto: only a stepping stone to a fully connected car.

Best dash cam: G-sensor

The G-sensor detects impacts and - usually - automatically begins a recording which is then locked to prevent it being deleted.

Parking mode: This may use the g-sensor, but is specifically for recording moments when your car is bumped or hit while parked. It doesn't guarantee you will see what happened, of course, as the camera points in only one direction. Also, most manufacturers don't recommend leaving the camera turned on when parked as it can drain the battery. Plus, many cars cut power to the accessory socket when you turn off the ignition, so you may need to get the camera hard-wired by a professional to use this feature.

Best dash cam: image quality

Most cameras record at 1920x1080 (the same as your full HD TV) but some offer higher resolutions, such as 2560x1440 and even 4K, although the latter is usually achieved by scaling up the video from a lower resolution, which is basically cheating. But, aside from "4K" models, a higher resolution is better as it means more detail is captured. Sometimes that detail - such as a car registration - will be crucial. This is why cheap dash cams aren’t always the bargain they appear. If they record at only 720p (or lower) you may not be able to see the details you need in the video. However, they will show how you were driving and what happened in front before and during an incident.

However, it's important to understand that the field of view affects how large objects appear. A really wide-angle lens (anything over around 120 degrees) will mean that cars appear quite small in the video and you will only see the numbers and letters on a registration when you're very close to another car. A wide angle captures more of the scene but with the trade-off that everything is smaller.

The other consideration here is frame rate. For smooth video you need at least 30 frames per second, but many cameras offer double this speed at certain resolutions. Frame rate usually increases as resolution decreases, and this is why, for example, the SJCAM SJ5000 can record "4K" at only 24fps. Also see: Apple Car rumours.

Best dash cam: Storage

Storage isn't usually an issue because all dash cams will record on a loop. This means they record for a couple of minutes, then automatically start a new file without a break. Once the memory card is full, it begins overwriting the oldest file. Many dash cams are limited to 32GB because they don't support SDXC, so check before buying a larger card. With most cameras, a 32GB card will be enough for about 4-5 hours of footage.

Bear in mind that only some cameras come with microSD cards. For those that don't, look for a Class 10 card (or better) as HD video recording requires a card with a fast write speed. Slower cards may cause problems and may not work at all. Here are the best microSD cards to buy

Also see: Smarter driving with intelligent cars.

Best dash cam: Wi-Fi

Cameras with Wi-Fi usually allow you to install an app and view recordings from your phone or tablet. This can be useful, especially if it lets you download recordings. However, transferring video over Wi-Fi can be painfully slow, and the videos trapped within the app and not easily sharable. Often, it's much easier to remove the microSD card (or even the dash cam from the car) and transfer the files to a laptop or PC. Either way, you'll see much more detail than if you review footage on the small, low-resolution screens on the dash cams themselves.

Best dash cam: Dual lens

Dual-lens dash cams are out there, but are in the minority. Some have a second camera built-in to the main dash cam, which faces rearwards and records the passengers. This can be useful in taxis, but if you want to record the view out of your rear window, it's best to go for a dash cam with a wired or wireless second camera. We've yet to see a truly good one, though. 

Best dash cams 2016: Safety features

Some cameras have extra features which warn you when you veer out of your lane, or you get too close to the car in front. These are useful if they only operate over a certain speed. Otherwise they tend to beep all the time in town driving, and so will be quickly disabled.

If a dash cam has a GPS, it may provide safety camera alerts.

Other features such as time-lapse recording, or slow-motion modes, can be fun but aren't essential. More expensive cameras may have two lenses, one which faces forward and one rearward. This means you can record what happens behind you and can be useful if someone drives into the back of you. It's generally better to go for a model with a second camera on a long wire as those with two lenses in one unit won't necessarily get a good view out of the rear window. Also see: Tronsmart USB Rapid Car Charger review.

Best dash cam: Accessories

Accessories vary between dash cams, but you can expect a fairly long power cable which is designed to be routed around your windscreen and down to your 12V socket. It's a shame that manufacturers don't provide a long USB cable instead, as you'd then be able to use a 12V USB adaptor with multiple USB outputs. If you use the included cable, you won't be able to use your 12V socket for anything else, such as charging your phone.

Since some insurers have a limited list of cameras, it's important to get one they recognise. However, if you change insurers regularly, it isn't worth paying more for a camera on one insurer's list.

Best dash cams 2016: Warranty

Warranty, as always, differs from model to model. Expect at least one year, but for cameras ordered from China, getting a warranty repair may be costly and take a long time. In fact, even if you purchase a camera from a UK supplier, it still may have to be sent abroad for repair, so it's worth checking if this is your top priority.

Best dash cam: Use your phone as a dash cam

With the right app, your smartphone can be used as a dash cam. It won’t suit everyone, but if you buy a universal smartphone suction mount and you can power your phone from your car’s USB or 12V socket, you’ve got a cheap dash cam.

Since most phones have GPS and record video in full HD, it can be a cost-effective alternative to a dedicated unit, and is a great use for an old phone sitting in a drawer. Android phones are good candidates, especially if they have a microSD slot. Otherwise you’ll quickly fill up the internal storage, and may not have much spare storage anyway.

Apps to try include DailyRoads Voyager (which supports 4K recording on compatible phones) and RoadAR. For iPhone we can’t recommend any free apps, but Car Camera DVR isn’t bad and costs £2.99.

Best dash cam: Conclusion

All of the dash cams here do a fairly decent job of recording your journey. You don’t necessarily have to pay more to get one with GPS, and this is a useful feature if you need to prove the speed, directior or location at which you were driving if you’re involved in an accident.

Wi-Fi is generally an unnecessary luxury as the only real advantage is being able to download clips to your smartphone. This is a slow process and in most cases it’s better to simply use a card reader (or the camera itself) and copy or watch the footage on your computer. You can also use their video outputs to review clips on a TV.

Initially we thought the lack of an internal battery would be a big problem, but it isn’t. The Transcend and Asus – like the other models – turn on when you start your car and turn off when you remove the key. While some support recording while parked, you’ll want to get professional installation for this to avoid draining your car’s battery, especially if you don’t use it for long periods. These 'hard-wiring' kits automatically cut power when your car battery voltage drops too far to prevent it from being completely drained and allows you to still start the car.

Safety features can be more trouble than they’re worth, and aren’t as sophisticated or reliable as similar features built into modern cars. The Dome’s are particularly useless, although for the price it’s still a good-value option if you want a GPS.

The SJCAM is a good option if you want a camera that can be used for more than dash cam duties. It offers great video quality but lacks some of the features you’ll find in a dedicated dash cam.
The Cobra’s integrated GPS is neat, but the screen is tiny and it’s the most expensive here. It’s not bad if you can find it for under £100, though. The Prestigio is the cheapest GPS option and is good value overall, even if the night-time quality is a little below par.

At £99, the Asus offers HDR video that’s better quality than most around this price and it also has GPS and decent sound recording. For most people, it’s the best choice. Also see: Best GoPro to buy and Why are people still buying satnavs?

Overall the MiVue 618 is well designed, easy to use and has some useful features, especially the speed camera warnings. Image quality isn't the best, but unless you plan to use the footage for home movies, it doesn't really matter: you can see the detail that's important if you're involved in a collision.

  • RRP: £179.99 inc VAT

As an overall package, the Nextbase 512G is one of the best, but at this high price it doesn't offer enough of a jump in image quality over cameras around £100 to make it good value. Some of those even come with SD cards. If you can afford it, it won't disappoint, but the Asus Reco Classic is better value at £99. Remember, though, that some insurers will give you a discount when you take out a policy if you have a dash cam: Nextbase cameras are most approved lists, so it may be better value for you than the Asus which isn't on any lists that we know of yet.

As a dash cam, the JooVuu X does a great job, and is good value considering it has both GPS and Wi-Fi. The lack of even a GoPro-like LCD screen is a shame, but it’s not a dealbreaker. Image quality is impressive and the timed mode switching is a real bonus. As an action cam, it benefits from being tiny and light but really needs a case to protect it. The fact that swapping in a replacement battery requires a screwdriver means it’s not as convenient as something like the SJCam SJ5000X.

If you want a dash cam with GPS so you can record your location – and speed – for extra evidence in the event of a collision then the RoadRunner 545GPS is good value. The mirrored screen is a bit annoying and quality isn’t great at night, but it’s good in daylight.

The K300 is a better choice than dash cams which include a second lens facing backwards on the main unit as you can position the remote lens pretty much wherever you want - even pointing out the side if that's what you want to record.
