What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

The A118 / B40 Wedge Dashcam Review

This camera has been on the market for quite a few months however I've only recently installed one in my car and I now plan to keep it there until either it stops working or something better comes along.

I must reiterate that this is a budget model and I really have have no idea how long it will continue to work for. I've received feedback that some cameras I've reviewed and rated highly like the 0803 can have short life spans especially in hot environments.

Given that I'm always testing a different model and I don't live in a hot part of the world, I just can't test a camera's long term relibility in a sunbaked car.  No one should expect a budget camera ito last as long as a premium model (with a two year warranty) but if your budget is limited and you want to know more about a particular device from people who have first hand experience of using it, I'd recommend looking through the forum on Dashcamtalk.


I have uploaded the sample clips here. Do not stream these as this downgrades the quality - you need to download the clips and then play them back from your computer to see their true original quality.

Muito bom artigo. Obrigado.
Gostava de saber se quando o cartão de memória fica cheio, continua a gravar substituindo os ficheiros mais antigos, ou se é necessário libertar espaço no cartão.

A couple of initial issues with my new A118/B40:

There is an option to input a vehicle registration, but it only appears to take 6 characters.

Movies appear to be a bit dark - trying a bit of +EV next.

The cable jacks/sockets for power and GPS are aligned with the display edge of the camera rather than the front side which will be against the windscreen. The GPS plug is quite long and sticks forward of the line of the windscreen. Picture here:

April 15, 2016 | Unregistered CommenterShep

If you use a right angled jack adaptor then you wont have so much of a problem of the plug fouling the edge of the screen.

I bought one of these wedge cams a while back and as soon as I'd fitted it I found I was getting interference with my DAB signal. I've narrowed it down to the camera itself by several steps - I now have a good quality 5v adapter, a ferrite-suppressed USB lead, the lead has been re-routed away from the aerial lead, the adaptor remounted away from the stereo. Running any other item from that lead, at that position, doesn't cause the trouble. Turn camera on - signal drops, off and it's back.

The only thing that has reduced the problem is making a little tin cover for the camera (barring the forward face, obviously) as a Faraday cage, and grounding that to the USB lead. This cut down the problem probably 80% but it's still there (more important now as the proper Planet Rock signal has been cut off around me and I'm trying to pull in the next nearest. It's fine without the camera on....)

Last night I knocked up a quick mount for my Mobius, to see it that would cause the same problem (I use it as an action cam usually, but would swap it over if it worked). Today I found the Mobius is about the same as the wedge+cover, so still not properly RF suppressed. It will be easier to make a nearly-full cage for the Mobius, but I'd rather find a camera that works out the box.

So, has anyone else had similar trouble, and any well behaved, RF-wise, cameras recommended?
Thanks in advance :)
(And thanks for the whole site, Techmoan... very very useful!)

Actually I'm having exactly the same problem with the second A118 I bought for the rear screen - as soon as power is connected, off goes both FM & DAB. I tried several different supplies but all 'give the same result. As I had no problem with the 1st unit on the front screen its probably 1 of 2 things - The 2nd unit is a 'cheaper & badly produced' clone which doesn't have the proper rf filters, or it could be due to the rear unit being closer to the radio aerial which is mounted less than 500cm from camera position - or maybe a combination of the 2.
I also considered making a faraday cage, but to be honest, unless its professionally made, its going to look pretty shit. So my current plan (no pun intended} is to spend a bit more & get an 0806 & see if that does the job.

If you're reading any of this Mr Techmoan Sir, how about including some kind of RF emissions test on future cameras - guess you'd need some kind of portable spectrum analyser (or just a dab/fm portable radio) ;)

Been using this camera about a week but cannot edit the videos in Windows 10 in anything, tried Registrator, HitMovie 3 Express and Windows Movie Maker yet double clicking them plays fine. Most sites say install Quicktime but Apple have discontinued this for windows rather than fixing the recent security holes.

If I boot into Linux every bit of editing software works fine with them so I guess it's a Windows codec issue.

On mine the high pitch whine is very loud, I think there are a lot of very cost cut versions of the camera around with a lot of RF noise, should have spent a bit more on a mini 0806.

April 22, 2016 | Unregistered CommenterMatt

Install the k-lite codec pack.

April 22, 2016 | Registered CommenterTechmoan

Turns out I can open them in Registrator fine, the error was the person between the screen and keyboard.

In the end found they work perfectly in Adobe Premiere Elements 14 so might just go down that route for my editing needs, out of interest what do you use to put your videos together?

Thanks for the videos and advice.

April 24, 2016 | Unregistered CommenterMatt

in IT that's referred to as a PEBKAC error (problem exists between keyboard and chair)

April 24, 2016 | Unregistered Commenterjokiin

Don't buy if you enjoy listening to the radio. Tried in 2 cars and it's completely destroyed radio reception in both.

I think it sends some frequency down the USB cable as short USB cables aren't a much of a problem.

July 22, 2016 | Unregistered CommenterGeorge Stone

I always recommending NEVER using the bundled cheap nasty and often dangerous power supplies that come with Chinese cameras. Try a good brand decent USB adaptor and quality USB cable.

July 22, 2016 | Registered CommenterTechmoan

Techmoan - I used a wiring accessory supplied by the dash cam seller to wire directly to fuse box and provide proper voltage to the A118. I still had radio interference. Is there a dash cam that does not interfere with radio reception? Really dumb if radio interference is a byproduct of dash cam use. What do you recommend? USA.

July 22, 2016 | Unregistered CommenterRandy

Re- Radio Interference, I got hold of another A118 last week to put on rear window.
To test its RF emissions out, I powered it via a portable 5v Battery supply & went all over the car with it while the DAB radio was on.
It worked absolutely fine everywhere, except when I came within 400mm of the radio antennae which is mounted above the rear window within the rear spoiler - Then it totally killed the sound until I moved it away.
So no good as a rear camera but great everywhere else.
Obviously, this 'Null' position is going to vary by car - but at least it proves it was nothing to do with the normal 12-5v power convertor that often gets blamed

July 22, 2016 | Unregistered Commenterrestyler

Very good review. Thank you! I bought this camera and it was pretty much satisfying me. However, it stopped working properly after some months. On the internet you can read that many people complain about the same thing, it stops working. Whatever the error (or cause) is it seem that A118/B40 camera is not a robust product, though the design and idea is great. Would be nice if Techmoan could robust dashcam models, of course I understand that such review would require time-extended cameras tests which might not be realistic to perform.

July 26, 2016 | Unregistered Commenterdaem0n

This camera, mounted in my rear window creates interference which renders my FM Radio virtually useless. I have mounted the camera as far away from the in-window antenna as possible but the problem remains. I have a choice, no camera or no radio. Has anyone managed to solve this problem? Camera is fed from rear seat lighter socket.

July 31, 2016 | Unregistered CommenterBarry Y

are you using a decent quality power supply...or the terrible cheapo one that came with the camera. If it's the latter, it may be responsible for some of the electrical interference, and it's worth trying a better quality USB power supply.

July 31, 2016 | Registered CommenterTechmoan

I have 2 of these cameras in my car, front and rear. The rear camera is located less than 6" (150mm) from my roof antenna and I get no radio problems at all.

I did run a live wire via a fuse tap in the front fuse box to an output socket in my spare wheel well, the neg wire from a local bolt in the wheel well, then plugged the rear camera into that after feeding and hiding the lead behind the trim etc.

July 31, 2016 | Unregistered CommenterLittleBob

Please help. Looking at getting a cam this shape asvits easy to hide but is there a version with similar video quality as the DDPai M6 Plus. Not worried about gps or wifi. Just like the way the M6 plus handles night quality and change of light conditions.

August 30, 2016 | Unregistered CommenterBigJP

Hi, I also have the camera and I'm pleased with the quality, but I encounter an issue. The sound is not in sync. I get video clips with the audio track from 2 hours ago. Also the settings are not keept in memory. It;s quite strange. I have the B40 Capacitor version. Did you encountered issues like this>

October 31, 2016 | Unregistered CommenterAu

Can't help you on sound because I don't record sound. No memory problems. Overall I'm pleased with the unit.

October 31, 2016 | Unregistered CommenterRandy

As there are many copy A118C version in the market, VIOFO have upgraded the A118C to A118C2 which use an improved F2.0 larger aperture lens, supports a circular polarizing lens filter, and comes with a new improved shielded charger. - See more at:

December 22, 2016 | Unregistered Commenterviofo

I have 2 problems with this cam
1) Card and memory error message comes up
2) The camera goes off and on every 7 seconds
Any solution?

January 5, 2017 | Unregistered CommenterHarold

My A118C powers up, records and plays back from the micro card, on the pc fine in the house. When I fit it in the car, it appears to do everything it should but the PC cannot read the files recorded in the car. Strange, because it reads the files when video is taken in the house connected to usb/mains adaptor power source. ???

October 5, 2017 | Unregistered CommenterMikey T

Mikey T,

Your problem is SD card. It is too slow and cannot record files completely and properly. Use original with 10 rating, not cheap Chinese copies. Also check if it is formatted with fat32 and NOT fat64 or ntfs.Logical sector size may matter too, use default size when formatting.
I used both 32 and 64Gb. Larger size cards will not work.

October 5, 2017 | Unregistered Commenterdaem0n

Absolutely spot on thank you. The new card worked straight out of the box. The card I had was 32Gb but was not class 10. A new quality card installed and the camera is working fine. Amazing camera for the price. Thank you so much for the info. I'm still learning this techy stuff! I'm OK with nuts, bolts and engines but all this giggledy gook catches me out!

October 6, 2017 | Unregistered CommenterMikey T

I have these cameras in four cars. In two cars, I installed cameras front and back. They work extremely well and only need attention during the transition to and from Daylight Saving Time. However, I just discovered a problem in two of the cars, both of which have AM-FM antennas integrated into the rear windshield. The cameras have the effect of attenuating the radio signals. The problem is so bad that I had both cars checked by their respective dealers, who could not find the problem. I finally isolated it to the cameras by powering them down, first the rear and then the front. Even though the antenna is in the rear, the front camera also suppressed the signal. The only solution is to remove the cameras.Would you be able to check this in future reviews? I'm looking for replacement cameras, but there is little information available about radio interference.

October 16, 2017 | Unregistered CommenterRich Roberts

Hi Rich Roberts!

I would guess many other cameras may emit noise. In my opinion, integration of AM/FM antenna into the windshield is not the best idea from car manufacturer. There are many dashboard-placed consumer products which can interfere... Naturally, camera with more-less powerful CPU/image encoder would emit all kind of disturbances and interfere (EMI) in kHz and even MHz range. Having some experience with electrical engineering I would experiment with simple shielding. For example, one can put an aluminum foil between camera and windshield (embed it into suction cup or camera holder) and connect to GND (-). Unfortunately, in most of the cases EMI shielding must be "water tight" implying that the whole inner volume of the camera shall be foiled and grounded. Smart electronic engineers would cover the CPU/noisy encoder with small grounded box like in mobile phones. But you don't expect such solutions for $30-50 cheap cameras ;-)

October 16, 2017 | Unregistered Commenterdaem0n

Thanks for your comment and suggestion. I know others have attempted to shield these cameras with foil and other creative solutions. Like you, I don't expect more from a cheap (yet capable) camera. But now I'm willing to pay more for a camera that is shielded internally. So far I haven't been able to identify one.

October 16, 2017 | Unregistered CommenterRich

Unfortunately/fortunately I’ve never had any dashcam I’ve tested cause interference with the radio in my car. Many people have told me how some cameras I’ve tested killed their DAB radio reception, but the exact same camera in my 2015 Mini hasn’t been an issue. If I ever do run into an issue I’ll report it..but it seems like the car is just as relevant as the camera for this test.
