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.

Hey Matt,

When you were testing this camera did you ever try or experience any issues recording in the 720p mode? I have tried several times recording in 720p and every time it looks horrible during playback on my Mac. It's just the 720p clips that look like it was recorded in a much MUCH lower resolution and then "blown up" to 720p scale.. When it's playing all the edges are very choppy/pixelated and the overall look is quite blurry. 1080p records fine and looks great playing back on the same Mac.

Also, to give a comparison, I have also recorded in 720p from my Mobius and played it back on the same Mac and those clips play fine and look great.

Has anyone else seen this issue with this camera, or any other dash cam in general? I'm trying to figure out if there is something wrong with this camera (firmware on the camera is 20150104), or if there is a specific codec or setting I'm missing on the computer? (Which would be weird since the Mobius plays it's 720p clips just fine)...

Any help would be greatly appreciated.

Hi Garrett,

I get the same issue if I try and use 720p playing back via a Windows PC. Also I have two of these both purchased at the same time from the same supplier both running the same firmware(as supplied). One for front screen one for back. But I did try them side by side and although the video is ok in 1080p they playback different in the respect of brightness and colour depth.

I have purchased several different car cams over the years and all seem to have a problem with using anything apart from what I would call there native resolution.

April 24, 2015 | Unregistered CommenterLittleBob

This is why 720P should be disabled on this model, not really a proper option to use and only causes confusion/disappointment.

April 25, 2015 | Unregistered CommenterPier28

Thanks for the replies and maybe confirmation..

Pier28, it appears you may have a lot of experience with this camera and maybe many others? Would you say that this is on par for this model dash cam and that the 720p setting on this camera should be considered essentially useless?

It wouldn't really bother me all that much if that's the case as I prefer the 1080p setting anyway. I'm just worried/trying to figure out if I have a damaged unit.

Thanks again.

April 25, 2015 | Unregistered CommenterGarrett

The only choice on the Street Guadian SG9665GC is 1080P

The GC is a super charged upgraded cousin to the B40/A118

April 25, 2015 | Unregistered CommenterPier28

I think your unit is fine. Just use the 1080p and forget about the other resolutions.

April 25, 2015 | Unregistered CommenterLittleBob

The 720p setting on any car camera is useless, it will never offer as much detail as 1080p with all else being equal, the Mobius is probably the only Novatek based product that has good 720p60 performance, they only need this for the smoother frame rate for RC use, it is still inferior for dashcam use, stick with 1080p and the better performance it offers for this purpose

April 25, 2015 | Unregistered Commenterjokiin

No problem. I won't give the 720p another thought.

Thank you all for your help!

April 25, 2015 | Unregistered CommenterGarrett

Hey guys, any ideas to help me?

I do use standard 1080 and stock settings but every other time I get the welcome screen freeze and nothing I do solves it

then randomly next time I'm in the car it works, so strange

April 25, 2015 | Unregistered CommenterMatt

It's possible the mini USB power source you are using is under powered if you're not using the included cigarette power cord. If not sounds like RMA time.

April 25, 2015 | Unregistered CommenterPier28

I'm using the supplied power cable, surely if under powered I would not get the welcome screen?

What is RMA? Sorry

April 25, 2015 | Unregistered CommenterMatt

A return merchandise authorization (RMA), is a part of the process of returning a product in order to receive a refund, replacement, or repair during the product's warranty period. The purchaser of the product must contact the manufacturer (or distributor or retailer) to obtain authorization to return the product.

April 25, 2015 | Unregistered CommenterPier28

Ah thanks.

I bought It via Amazon - contacted seller but no reply so have issued a claim with Amazon

Let's see what happens

April 25, 2015 | Unregistered CommenterMatt

Just bought one and it seems as though the camera causes interference on the radio reception

May 3, 2015 | Unregistered CommenterTyke

I have my had my A118 installed (hard wired) for a month or so, had a little trouble with it switching on by itself sometimes but seems to have sorted it self out, but regarding interference with radio etc I have had no problems ? everything fine ? touch wood quick. TB

May 5, 2015 | Unregistered Commenterscaniaman

Not that you care but I am pretty sure your audo wine is caused by the 12V USB convertor.

The convertor uses a switched mode power driver to drop the voltage and it is this circuit that I think you are hearing.

Try another convertor or a better quality one :-)

Hi there, I have just seen some of these new Xiaomi 10,000 mAh powerbanks very cheap. As they are about the same size as a mobile phone I have thought of running my dashcam from one of these hidden behind the sun visor. The question is, how long will the camera run if plugged-in to one of these ext. batteries? Thanks.

May 14, 2015 | Unregistered CommenterJay

problem with the powerbank is they take so long to recharge, not really practical, better to just run them off the car as intended

May 14, 2015 | Unregistered Commenterjokiin

Thanks for the info. But what if I want to record activity while the car is stationary, vandalism for example. How many hours could one roughly get from a 10,000 mAh powerbank (recording at Full HD, 24 f.p.s.) Thanks.

May 15, 2015 | Unregistered CommenterJay

Purchased and direct wired the A118-C (capacitor) in April 2015. Professional did the install. Radio interference is terrible. Tried three different automobile circuits, and two different direct wire kits. Finally direct wired the cigarette lighter power cable using a female socket. Radio interference continued. All purchased from Spytec in New York, New York USA. Installed in 2013 Ford Flex.

May 15, 2015 | Unregistered CommenterRandy

Hi Jay,

The unit has a 300 mAh polymer lithium battery.

So fully charge it, set the unit how you want to use it(motion detec etc), then see how long it runs before it switches its self off. Now just divide 10A power bank by 0.3A = 33.333 x the mins it ran before switch off.

lol - say 10 mins x 33.33 = 333.3 mins = 5.55 hours, -15% for rubbish power bank = 5.27 hours.

Note - that continuous record or motion detec are going to get totally different results etc.

If they are so cheap then buy one and test. Put us all out of our misery - hehe

May 15, 2015 | Unregistered CommenterLittleBob

I cannot believe I missed this one, this is exactly what I have been looking for.

July 18, 2015 | Unregistered Commenteraxel

@axel if you like this one also check out the SG9665GC for premium results.

July 18, 2015 | Unregistered CommenterPier28

Yes, I am aware of the SG9665GC, I have been on Dashtalk, I may pick one up after I try this one out for a while, this was my first dashcam, and I have been thinking about it for at least 2 years, Techmoan doesn't make recommendations, but if you listen, you can tell when he likes something, the form factor was perfect, but to be honest, I would have preferred a smaller cam without the screen. I have mine wired into my car's NAV display for setup. cheers

July 23, 2015 | Unregistered Commenteraxel

My car recently received considerable damage whilst parked in the Supermarket carpark. I have 2 of these cameras, front and rear and they had both died in the few days prior to the accident. I say "accident" but the B*****d didn't stick around and left me with £1600 worth of damage. What a pity I couldn't record him/her.
If you mount one of these cameras in the back screen make sure it is not mounted over any radio aerial wires in the glass or it will cause radio interference.
Does the capacitor version perform any better?

August 6, 2015 | Unregistered CommenterBazzza

That's very unfortunate. I also have one front and rear in my car and they are hard wired to the car ignition. Both are working fine, I also have an override switch so can leave them on when out of the car if necessary.

August 6, 2015 | Unregistered CommenterLittleBob

Hi Mat,

What do you think about this cam? It seems similar to B40. Is that from the same manufacturer?? Any idea about this one?

having waded thru' tons of videos/reviews have settled for the "wedge" as you call it; one slight reservation is i want to be able to move it from one car to another, seeing that the support is permanently fixed to the screen with double sided tape what would be an easy workaround?

ps i'm not a DIY'er by a long stretch , hence the question !!!

August 25, 2015 | Unregistered Commenterterry

If you want to use the camera in different vehicles, do what i did, contact the seller and purchase extra mounts. Install one in each vehicle you plan to use the camera in and then you can move it as needed. You can also purchase extra hard wired power cords if you like for each vehicle.

August 25, 2015 | Unregistered CommenterRaider21

many thanks, have contacted seller
