Life with a dashboard camera – my first impressions


We’ve heard that many of you would consider buying a dashboard camera to protect yourselves against scams on the road. So we bought our own to see what life with a ‘dashcam’ is like.

If you’ve ever spent any time on Youtube, chances are you’ve stumbled upon videos where unhinged drivers slew across the road causing chaos and destruction, felling lampposts and forcing pedestrians to dive out of the way. These are all filmed on dashboard cameras.

The reason so many people are resorting to dashcams is not to become Youtube tycoons, but to protect themselves from scams on the roads. In our poll, 59% of you said that you would consider buying a dashboard camera, so we thought we’d buy our own and see how we got on.

Easy to use, but prices are high

I went for a NextBase In-Car Cam 402G Professional as it offers full high definition recording, GPS logging, a wide angle lens plus motion detection and a G-force sensor.

And the price for all this? Just short of £150. That may sound expensive for a potential defence against scams, but a number of dashboard cameras cost over £300, so this NextBase represents a typical mid-range model. Add in the fact that several car insurers offer discounts of up to 15% if you own a dashcam and the price seems much more palatable.

Fitting the NextBase is simple with a satnav style suction cup that attaches to the windscreen and a long power cable that plugs into a cigarette lighter. Press the on button and the dashboard camera records until you switch it off.

However, even in the week I’ve had with it, sometimes it felt like an effort to fish out the camera, plug it in and arrange the long power cable so that it wasn’t dangling down in front of me. I ended up looping the power cord over the passenger sun visor. Although, if you plan to keep the mount in the car, you could feed the wire around the windscreen more discreetly.

Image quality could be better

The main reason to buy a dashcam is so you can provide evidence that you’re not to blame for an insurance claim. So, image quality is paramount. If you can’t make out number plates in all conditions then your dashcam isn’t really fit for purpose.

Based on our first few outings the NextBase seems to provide reasonable footage, apart from in darker conditions where number plates were often illegible. However, this may be down to my car’s heated windscreen, which gives night images a speckled quality.

If you already own a dashcam, how are you finding it? And if you’re considering buying one, tell us why.

Hi Mike, thanks for your comments. The closest we’ve tested are dash cams – you can read all our reviews here:


All dashboard cameras should be capable of filming at night. However, even the top-performing model in our tests left room for improvement with its night-time image quality.

I am putting off buying a dash camera for a while as this idea of a camera and screen is far too clumsy. What is the point of having all that and trying to hide it behind the rear view mirror.
What is required is a small HD camera behind the mirror and the screen equipment that can be viewed if required tucked away some where in the car, there is absolutely no point in having one on your windscreen if it comes to that it’s a distraction and looks terrible. I think there is only one on the Market just now at a reasonable price that is like stated. So to sum up small HD camera only behind mirror really thin cable ( easy to hide ) going to the main screen box that can be hidden in car. ARE YOU LISTENING MANUFACTURERS. IAN. JHK1V

i bought a dash cam today, all be it basic, but its £25 with good quality sound and video, i know the reasoning behind these and believe it or not 5 minutes after buying it i had some idiot drive into my car n try and blame me, roll on the insurance lol.


I bought the NextBase 402G solely on the “Which” best buy recommendation, there is so much “choice” out there, it gives me a head-ache.

“Which” : I am far from delighted.

1) The 402G is not recognised as a USB device and I cannot find any Win7 drivers to enable that.
THis means I have to fiddle the sd card out and into a card reader then vice-versa when I want to view any footage.

2)The play-back software works after a fashion, but its clunky and difficult to navigate. It dose not stay selected on “Protected” files, every time you change folders, you have to re-select for “Protected” or wade through the lot. Who has an hour or more to spend hunting through a half hour journey?

3) The glaring error is that, when a file is manually protected by the driver following an incident which occurs very near the end of that particular file, the incident itself and lead-up may well be lost and just the aftermath saved…too late.

Protecting one file should also protect the preceding and next file to give a full story.

4) The NextBase website is a disaster area with broken links left right and centre. Even their “Contact” form doesn’t seem to work and strange things happen. Certainly no acknowledgement or reply has come back to my eMail yet. I’m not holding my breath.

Thanks a LOT, “Which.”

Yours sincerely, disabled and low income pensioner.

The 302 has similar issues. It does recognise as a block device when connected by the USB lead, but is very slow! 1Mbps transfer rate 😛 . Taking the card out and using the built-in card reader, it is 16Mbps transfer rates. If you wish to play files back on a PC/laptop/whatever, copy them off the SD card to your device and play from there.

Yes, the big downside to this camera is the lack of a protect file button without using G meters, not worth enabling in places like Reading. It would be nicer to have a simpler way of recording and protecting minor shunts, road rage and the like without having to remember the time of the incident and doing maths to find the right file!

Bought the nextbase 420g last week and I found it easy to use, if you have a PC that can view HD video in .mov format (QuickTime MP4). You need a class 10 micro SD card £15 in tescos for a 32gb, which will give you over 400 mins of record time @1080p full HD. Installation disc has all instructions on and software to view journies with all stats including heavy braking/acceleration all linked to google maps. Hide the cam behind the rear view mirror and tucked up the cable along the roof lining quite neat and tidy+ I put black tape over the white lettering making it not stand out. Image and audio recording is very good crisp and clear, even at night I was surprised how good the image was
420g price 9/10 quality 9/10 easy to setup 8/10 performance 9/10
Also comes with hdmi cable to play back on your TV,nice!

I am totally satisfied with the research into this model and the mixed comments………I would really like to purchase a camera that fixes on or in front of the inside mirror and also one that provides me with a rear view as well………. Would someone please comment very soon… 29/4/2015…….

This is basically a plug and play device. Image quality is one of the best. I have used professional in car cameras with work, this unit is far better at a fraction of the cost. It has settings that can be adjusted for better view clarity, you need to read the instructions to get the best out of it. For the price it offers lots of high end technology. I would recommend this to anyone wishing to have that piece of mind whilst driving.

i want a dashboard camera that will record front vision and record rear view traffic-preferably one that will fix onto the interior mirror., somewhere in the region of £50- £100…..which one? Please comment….. Thank you……..


I’m glad to let you know that our Cars Team have reviewed plenty of dashboard cameras here:


I’d also have a read through our really helpful, online guide about buying the best dash cam for further information 🙂 :

Just a thought.Why is it called a dashboard camera.It’s nearly always attached to the windscreen?
I use a mobile app camera,Such a lot less fuss involved.If nothing happens-and nothing has for 50 years- just delete it later.

I have bought a cheap camera for myself and also for my daughters car. I just cannot believe what happened today. My daughter had her car in for MOT. It failed because she had the camera installed on the windscreen. It is fitted just slightly above where the tax disc holder used to be. I cannot believe that this is classed as an MOT failure. Does anyone else have any experience of this.


Yes. The MOT regs now require all appendages to be removed from the windscreen… cameras, mobile holders, notebook holders, etc., but I only find out when my MOT was also refused and the change was then confirmed by my garage. I would have apprecieated being told about it before they took it off for the test!

K.ingram says:

You cannot have any obstruction or damage above 10mm in zone”a” or above 40mm on the windscreen swept area.know the mot rules and you won’t be so surprised when your car fails its mot.as an mot tester you are given the option of removing items from drivers view before the test starts.

Is there a remote battery or power source available for the 402g? I have just bought one after my car was damaged at work by a hit and run but the built in battery only lasts for 6 minutes. Also, if i hardwire it to the car battery/fuse box how much of a drain would it be to use it for the day, every day to protect my car from damage again by hit and run?


The 420g manual gives its consumption as 5V 600mA – so 3 Watts. If your battery is in good condition it should not be a problem. There is a lead provided to connect to a car auxiliary socket. Provided that is always live (not switched by the ignition) you could use that.


The built-in battery on the 402g model is only intended to operate the camera for 6 minutes to maintain operation in the event of temporary interruption of supply. On most modern cars, power sockets are only live when the ignition is ‘on’. Some owners do modify power sockets to provide continuous power, but it is essential that a fuse is included in the supply.


I have mine plugged to an Ignition-on socket; the camera switches itself on and off quite happily.

In spite of that, my previous observations ( 8 April 20150 still hold, but I’m stuck with this one as I can’t afford to shop around for another without the failings I mentioned.

I don’t understand the numpties who gave me thumbs down for that comment…its simply my experience and valid observation…don’t you like truth or what?

I have the next base 402 dash cam and now it’s decided not to turn on and I don’t know why. The blue light is on but no image any ideas and its warm to the touch


Can you get in to the settings menu?

There are different timings available for how long the screen displays after start-up. It should be on at least when it starts, then switch off after your choice of time so as not to be a distraction whilst driving.

If that doesn’t work, its probably cooked.


find and press the reset button

Using the 302G, I get some very loud static interference on the audio while driving, which dies down when the engine is idle. This is happening with two units, one exchanged at Maplin, which suggests a design or manufacturing fault. Has anybody else had a problem with horrible crackle on their video?

derek says:
12 February 2016

I have the same crackle interference , don’t know what to do ?


Derek -there are two possible causes – radiated interference or interference traveling up the power cable . If it is traveling up the cable then you can buy iron cored inductors to clamp on to the power cable to depress the pulses of interference , just like you have on good computer LCD screen cables ,you know that large black lump attached to the cable . If it is radiated then change the power cable for a better higher priced screened cable ,cheap ones are rubbish.

I’ve had no problems with this camera whatsoever. I’ve set it to record in 5 min loops. Someone was worried about losing the lead up files prior to a crash. Maybe a longer loop setting would help. Also, don’t just rely on having one micro sad card in the car, I have 2/3 micro sad cards, so in the event of a crash, I’d just replace the whole card. If you own a phone like a Samsung Galaxy you can also put the micro sd in there and transfer any files to the camera for safe keeping in the event of a crash.

As for transferring the the files to the PC, I have used the camera itself and connected to Win 7 pro with no problems. I have also just put the card in a card reader. I don’t use the software provided as I have my own (Cyberlink) for play back.

I’d highly recommend this camer.

I just bought after a bit of research,a Garmin 10 dash cam from Messrs Halfords in Norwich today. Get the damned thing home,unpack it only to find the power cable is woefully short. In my bitter experience in order to make the the cable “invisible” and neat and tidy,you need something like 3 metres to run it up the door pillars etc…I don’t want it “hard wired” to the vehicle. It’s a GARMIN. Now I don’t know about these things,but I naturally thought with all their expertise and experience that a power cable of a suitable length would be in the pack! Well of course it isn’t!! So here I go back to Halfords. Now, nobody was especially keen to sell it to me,can you imagine how they will cope with me asking for my money back? This could be good? Am I ever gonna find out how good the device is?


I’ve had a Smartwitness for about 18 months now. Last week somebody hit my car and left no details. Went to get camera footage from SD card – guess what? Card unreadable!!!!

My advice for the future – probably to regularly pop the card out and make sure its still working. Bit of a chore frankly


I have just purchased the 202 model, spent 4 hours trying to get it set up with a brand new 32g card. I keep getting “sd format error” which my vista PC won’t rectify and the USB connection does nothing also. The camera is now stuck in “sd card error” and when trying to change any setting it has a mind of its own.
One more try tomorrow, if still having problems then it’s going back to Halfords.


my nextbase 402g in-car cam wont work with the supplied cable, anyone know why please

I bought two Nextbase 402G’s just over a year ago. One of the two didn’t work and was replaced by the retailer. I needed to check the video last week, and found it hadn’t recorded anything for ten months because the memory card was full; it seemed the memory management system wasn’t working and deleting older videos to make room for more. I then checked the other camera (in my wife’s car), and exactly the same problem. No matter what video loop setting we use the file management software doesn’t work.
The cameras give no warning, and continue to indicate that they are recording even though they are not. A working dashcam is invaluable but this particular model is expensive rubbish.

I bought the 402G in March of this year. In comparison to my previous camera, the video quality is very good and can be adjusted for various lighting conditions via the menu. Until today, (16/09/2016) the camera has been fine. I regularly downloaded the content and used the in camera facility to format the SD card, keeping the unit “tuned up”. However, the menu is not accessible when the unit is connected to the computer so depends on the inbuilt battery. In short, my battery has failed resulting in any access to the menu impossible. It appears that this is a common problem with the built in battery. Mine will be going back to Costco for a refund ASAP.


I’m surprised there has only been one mention of a DashCam App in this thread!
I researched DashCams around a year ago and there seemed to be problems with them all! Poor nightime visibility, narrow viewing angle, no crash detection, no web upload facility, etc. There was no single camera that appeared to come out best in all categories.

So why pay hundreds of pounds for a device you are never fully happy with?

I didn’t…
Instead I searched through the many DashCam Apps in the G**g*e Store and settled on AUTOGUARD.

Autoguard has HD recording, a wide viewing angle, crash detection (with auto upload feature), continuous recording after crash, background recording (when using another phone function), Google Maps tracking, amongst it’s many features. Admittedly the camera is only as good as your smartphone camera, however if you have a fairly recent android or apple phone this shouldn’t be a problem.
And Finally the cost was £6.99! Worthy of a try when compared to the cost of the stand alone units, I think.

Autogaurd is just one of several DashCam Apps available, and the one that suits me the best. Many allow a free trial so my recommendation would be to try before you buy and certainly don’t buy an expensive DashCam if you already have your phone in the car anyway!

Thanks for the review, but as part of this feature I think perhaps Which? should review some of the top rated DashCam apps to give a comparison to these more expensive DashCam units.


I am planning to travel in New Zealand but was rather amazed that they do NOT have to have car insurance in New Zealand. I am seriously thinking that having a dashcam, whilst it may be useful to catch anything untoward, may not be all that useful, what use would it be if the other person was not insured. Anyway, think I’ll go and get one as a bit of added “insurance”, might get a better rate at the car hire dealership – well I can always dream can’t I!?


I hope you dont intend to live permanently in New Zealand a large number of the population leave New Zealand for life elsewhere and watch their equivalent of “Bad Neighbours ” its an eye opener ,even the programme admits its citizens arent too happy.

Flawed product
This is a great camera but has a fundamental flaw – after 12-18 months it won’t record an accident.
The battery fails after 12-18 months of use. This then causes the camera to corrupt the last file when the power is turned off.
So when you have a crash and turn the engine off – guess what – the file of the crash is not saved!
So the one time you want it to work it doesn’t.
We learnt the hard way – shame because when it works its great, but to have product that lasts just over 1 year and then has to be replaced or worse you have an accident and find out this expensive product is flawed is terrible. Cannot excuse the poor quality of this product. Potentially great but bad product design and money saving in production means this is not fit for purpose.

After reading the WHICH review on dashcams i purchased 2 Nextbase 312GW (front and rear) from Halfords Mile End – London.
The customer service was OK. The fitting service (2x £30) did a good job, but the gentleman refused to wire to a live feed. He stated that ‘he’d be fired if it went wrong!’.
This was disappointing – we wanted it to trigger on movement on our private drive and monitor a vandal who’d been piercing tyres with nails. This is our 6th tyre!

I contacted NextBase who said no (warranty) issue with live!
“If a camera is wired into a permanent power supply this can put a lot of strain on the SD card, as long as you format the card on a regular basis it should be fine”
…however Nextbase refused to intervene in the discussion with Halfords, the Nextbase retailer and fitter. Instead leaving it to me to resolve. IMO this is poor support from Nextbase!

I hope its not an indication os their after-sales.. or willingness to ‘help customers get matters resolved’
Sometimes good products are led down by careless customer experience.


Hi Rajiv,

I recently looked into getting a dashcam and powering it with the engine off. My investigations led me to discover the vast range of batteries out there that may or may not be suitable and various ways of charging them. I am not recommending this site as I have never used it but http://www.allbatteries.co.uk/ might give you some ideas.

You might want to consider an external camera to catch your vandal. In the winter months, windscreens get covered in condensation so might not record anything external to the car.

Rajiv Abeysinghe says:
29 September 2017

Thanks Alfa… appreciated.

Have you done research on 4G external cameras triggered by movement ?

NB: We park our car in an internal, locked car park for around 50 cars. The windows aren’t impacted by frost.


Sorry Rajiv, I haven’t researched 4G external cameras.

If your requirement is short-term, I think I would go with a separate battery and get a couple of SD cards to swap around. I think you can get a separate battery to charge when the engine is running or even get a couple to swap out while the other is charging indoors. It should be cheaper than keep having to buy new tyres.

p.s. If you log in to post, you will be able to check back at your history to see other answers in the future.

You do not want a dash cam you want a movement sensor connected to a camera or a security camera system covering your drive which will record all movement |I suggest you look into a security camera fitted outside there are many types including radio controlled ones which do not need any wiring at all


I purchased a Nextbase 402 in Sept 16. I am very disappointed that it stopped working after 13 months,so now out of 12 month guarantee. It repeatedly fell off the windscreen as suction holder not adequate. The long wiring from holder to cigarette lighter is clumsy and gets in way of front passengers and presents a potential trip hazard. Not recommended!
