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%!

K1S - The first Front & Rear Hidden 1080p Dash Camera

My full video review for the K1S 2ch HD Car DVR is below. 
If you want to watch my 'Beginners Guide To Dashcams' video - Click here.
The K1S manufacturer website is here, and pdf manuals for the camera can be found here.
For my downloadable sample videos click here  As always, download these files to your machine before viewing them - streaming will make them look worse than youtube.
Note: These files have been manually trimmed for length (and filesize) - therefore the start and end points for the front and rear clips no longer match each other perfectly.
Size Comparison
The control unit is approximately the same thickness as a box of cards but a bit smaller overall (without cables).
Buying the K1S
I’ll add links below as and when I discover additional resellers.

UPDATE 02 March 2015
I've received the answers to a few questions I asked the manufacturers.
1) The Car Lamp Open/Closed menu as expected does warn the driver if they are driving in the dark with the headlamps off. It judges this by the exposure.
2) Apparently the battery used is a Standard GoPro size....which is great. Normally I try to avoid dashcams that use batteries, because when the internal battery fails you have to replace the whole camera - in this case you can buy a new battery. Just a reminder -  I can't comment on the long term reliability of any cam after only a month of use.
3) I wasn't sure how the emergency button handled the files. I was concerned that if you saw something you wanted to keep - but the camera started recording the next file before you managed to press the button then you would be protecting the wrong clip. Well it turns out the manufacturer has thought of this. "When this button is pressed, if current recording is less than 1 minute, then current file and the file before this (together 2 files) are locked"
4) Not a question, but I have raised the issue of the need for resellers in China who can export to Europe and also the Speedcam database is no use in the UK until the camera can support additional database formats. Both these things are being explored...but the database issue isn't a simple quick fix.
Both my cars had a K1S installed until a couple of months ago - They were still working 100% at the point I took them out. I removed them so that I could test other cameras, although I was getting a bit sick of the rear wire interfering with the rear hatchback door on both cars - this would work better in a car with a fixed rear window.  It seems that my experience is not the same as that of other people - perhaps the manufacturer changed the product after I purchased my cameras...but if you read through the comments it seems that other people are having lots of reliability issues. You may have noticed that this is no longer on my list of Recommended Cameras - and this is the reason. I was happy with the performance of both of my cameras for 18 months...but perhaps my experience was uncommon.

It's too bad the audio is so terrible on the current version of K1S. (totally unacceptable) You can barely hear anything. If you don't need audio $199 isn't a bad price from SpyTec, Inc. I doubt it's anything that can be fixed via firmware, so hardware has room for improvement.

@DESFORM, tried the D36, totally unstable, don't recommend unless you like frustration. (bought two, both were the same)

March 19, 2015 | Unregistered CommenterPier28

Excellent! This is the price point for me!

Question Mat... Will the one in the US Amazon links (SpyTec) be identical to the Koonlung one which you reviewed, or will they have different image quality etc?

Pier28... I think the 1* review you left on Amazon (under your alter ego 'JazJon') is unfair if the only issue you had was the microphone. This isn't important to everyone, unless you can expand on other reasons you only gave 1*? Is it because you won't be selling it on your online shop by any chance?!

March 19, 2015 | Unregistered CommenterTheCarMadDad

Mat, surely with SpyTec using your review video on their website (, they could do a special offer to all your subscribers of free delivery to UK and wangle something with Mr Import Tax Man Bloke? Couldn't they? Put me down for two!

March 19, 2015 | Unregistered CommenterRiggers


If people want to order the K1S from outside the U.S., they should order it on our website rather than through Amazon. USPS 1st class rates are generally pretty reasonable. Also FYI, ordering USPS International 1st class often allows one to avoid paying import duties .


March 19, 2015 | Unregistered CommenterSpy Tec

Thanks PIER28 for the warning about the D36

What price did u buy one ? unreliable about what are they ?

ANYWAY concept 2 lens cams one DVR are bound to come some days, because this is what most people want, not these ugly ducklings DUAL CAMS like the ones we see on ebay when we enter key words ""dual cam dvr""in the search

SURE ENOUGH, if MOBIUS INVEST THE MARKET, I think they would be much sucessfull, with no doubts...

HOPING, someone with enough money can get them K1S from china in bulk and resale them here in Europe, BUT preferably not in UK because their pounds rockets up any prices + the postage, it ends up being like u get it from the states

March 19, 2015 | Unregistered CommenterDESFORM

@TheCarMadDad, I stand by my 1 star review. The super low weak audio is a total deal breaker and people should know. If Koonlung fixes it I'll gladly update the review. Also there is no such thing as a Roadcam or SpyTec "Brand" K1S edition. I'll be monitoring things and hope it gets fixed.

March 19, 2015 | Unregistered CommenterJazJon

Well, I've just purchased directly through the SpyTec website. It was fairly painless to be fair! I chose the USPS 1st Class shipping as advised by SpyTec above. If anyone is interested the total price including shipping was £152.97, which I think is quite reasonable. It could be more if I end up getting import duty charges. Up to 14 day wait now :(

March 19, 2015 | Unregistered CommenterTheCarMadDad

@TheCarMadDad Look forward to hearing if you have to pay duties. If you don't then I think I'll take a punt.

March 19, 2015 | Unregistered CommenterRiggers

@ Jazjon - Seems a bit of an odd way to rate a product - I start by assuming everything is entitled to a maximum score and then mentally take points off for things I don't like (but everyone is entitled to their opinion - no one can be wrong when it comes to opinions). My score 4 out of 5.
If sound is vital then all pre 1930s Laurel & Hardy Films could be considered useless...but 'Big Business' - a 1929 Silent film where Laurel & Hardy try to Deliver a Christmas Tree to James Findlayson is one of my favourites.
Anyway, I've put a K1S in both my cars now.

March 19, 2015 | Registered CommenterTechmoan

Can someone post the link fo rthe direct purchase on their website please.
i cant find it..


March 20, 2015 | Unregistered Commenterhughdunit

You can not find the link because does not exist.

March 20, 2015 | Unregistered CommenterThanos

The website you are looking for is

Being a US store it's pretty much guaranteed that you'll be charged import duty if you live outside the US.

I am thinking of getting this for my motorcycle. I have a vstrom, very similiar in size and layout to your bike. Do you think this could be installed in a motorcycle nicely? I am thinking I could mount one camera somewhere in the front, perhaps underneath the light cluster and one on the rear near the fender. HOWEVER, i figure the main problem is this isnt waterproof and wont be easy to remove when it rains. This with waterproof cameras would be the ultimate motorcycle dashcam/black box.

March 21, 2015 | Unregistered CommenterMike

This is not suitable for a motorcycle.

March 21, 2015 | Registered CommenterTechmoan

Thanks for responding techmoan, my search continues for a tiny remote water resistant camera i can install on the front of my motorcycle with the brains elsewhere attached by wire!

March 21, 2015 | Unregistered CommenterMike

Hi Matt, thanks for the reviews. My cheap mirror camera with rear camera quit working, I have been looking for a better replacement that is still a bit stealthy, and today an old woman ran into the back of my van, said she did not and drove off, side-swiping a car as she pulled into the lane to get around me,stopped and cursed them for being in her way, and drove off.
Such a dangerous and nasty driver, and she could have been off the road if any of us had had a front/rear dashcam.
Any idea of how reliable the K1S will be, as I know Street Guardian said the K1 was rubbish?

I've just ordered a K1S from Spytec... well, I've actually ordered two but one was from Amazon before reading the comments on here! Fingers crossed Spytec cancel the amazon order as requested!!

Roll on up to 14 days!

I've also put an order in for some 90 degree rear angle Micro USB adaptors to drop the wires down the back of the main unit rather than have them poking out the side, £1 each from some Chinese seller on ebay so fingers crossed they all come at the same time and a nice discreet hidden install is on the cards :)

March 22, 2015 | Unregistered CommenterDave

@ Brett - there's no-one on the planet who is able to advise of the long term reliability of the K1S yet - since it's only been out a few weeks. I'm now using one in both my cars and the short term reliability is great.

March 22, 2015 | Registered CommenterTechmoan

@Techmoan - I've had a quick look at the Navitel DB, and it is nothing more complicated than a Comma Separated Values (.csv) file.

I've got a hunch that the Pocket GPS World database will be able to be used in the K1S by downloading it as a .csv file and reformatting it to the same header as the Navitel DB. This way, us UK lot would be able to use the speed cam functionality.

Of course, this is provided that modifying the PGPSW DB is allowed by their Ts & Cs. If I can find anything out I'll report back.

March 23, 2015 | Unregistered CommenterDave

hey dave. Is there anyway I could get the data from pocket gps world for usa.. more specifically california? I am thinking about doing the excel work and give it out for free.

I guess I can manually add some in my area and expand out.

March 24, 2015 | Unregistered Commenterchris

Anyone else have their Spy Tec order cancelled or is it just me? Website now says it is on backorder; email they sent says "currently not available with no ETA".

March 24, 2015 | Unregistered CommenterKarel

Karel - me too... on the hunt for another seller.

Chris - the PGPSW database is strictly copyright enforced - I'd not recommend 'open sourcing' it at all. Also, I don't think they cover the USA unfortunately.

I imported the Navitel DB into Google Earth and it seems to cover Spain, Eastern Europe, Russia and (bizarrely) London inside the M25.

Anyone have any other ideas for sellers of the K1S?

March 24, 2015 | Unregistered CommenterDave

Thanks Matt, good to hear it is still working with no hitches, even if it has been only a few weeks.

Spytec told me that they expect more K1S' in next week.

Perhaps the newer ones will have the audio hardware problem fixed?

Also left a message on Koonlungs facebook page asking about buying from them and the price being higher than their reseller, they have not answered,, no surprise. Probably charge more to protect the resellers.

March 24, 2015 | Unregistered CommenterBrett

Well I guess i'll just manually input it.

March 24, 2015 | Unregistered Commenterchris

maybe we could use google docs and make one?

March 24, 2015 | Unregistered Commenterchris

@brett not sure where you got the idea Street Guardian says the K1S is rubbish, I've made no such statement and nobody else speaks on behalf of our brand, if you've taken something out of context or misinterpreted as being a comment about this product then please let me know where and I'll address it so that it's perfectly clear

Build quality of the product is good, a lot of issues since the 2013 version of this product (the K1) have been improved enormously, the audio is currently very poor and needs improving, I'd expect to see that improved in the next version as currently it is the only major issue and it has been brought to the manufacturers attention already, there's some minor things that could be improved also but not deal breakers

Of the other dual remote camera products, IRO, Kome etc this is certainly the better of them, not perfect, but far from being rubbish

March 24, 2015 | Unregistered Commenterjokiin

@jokin Hi, don't know where you got the idea I said said the K1S was rubbish? I have re-read my comments, and all I said was that Street Guardian said the K1 was rubbish. To the best of my knowledge, which is very limited, Street Guardian has not reviewed the K1S.
Perhaps you could enlighten me?

March 24, 2015 | Unregistered CommenterBrett

@brett, perhaps you could enlighten me, you said we said the K1S was rubbish, news to me, maybe you're confusing someone else's posts for mine

and yes I have the K1S, have had it since October last year, have not posted any reviews on the product, nor will I

March 25, 2015 | Unregistered Commenterjokiin

@Karel Mine is definitely on its way, i've had the tracking number. It's currently in Jamaica, NY. Perhaps they only had a few in stock?
