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.

At the $ price quoted I think the price is fine,but by the time it gets to UK via a distributor who can support it on a technical level it will be twice the $ price. My concerns are : The battery (I would rather have capacitors to take out spikes), Current drain from the vehicle battery (I want it off when the ignition is off) and reliability (It gets very hot in a windscreen in the summer even in UK). Lastly I have heard reports of RF leakage causing DAB problems (not with the K1S yet). With the amount of complex electronics in modern cars cameras need to be well screened. The last thing I want is to cause a problem by introducing an expensive, unsupported product.

Great review.
Hope in long run big Korean names will start manufacture dash cam with separate main blocks.
I was looking for similar cam for a while and I was able to find model named:
Iconbit DVR QX DUO.
I guess it is manufactured in China for Russian market. Also they have office in Germany.
I emailed them and asked how much it would cost to UK.
They responded 'We offer the DVR QX DUO for 179,95€ plus 15€ shipping'.
At meantime there is a older model of it on Amazon UK:

I passed on it as according to feedback from russian bloggers (in russian), there is a big problem in performance of latest model.
It is unstable and can 'freeze out' without a reason and customers have 'permanent headache' with it.

Could you give us feedback how is performance of this cam on later stage?

About parking mode.
Usually for that to perform you should connect dashcam with Uninterruptible Power Supply directly to fuse/battery.
That looks after battery and when car's battery is discharged to set level, it stops parking mode.
Do manufacture have this on offer?
As myself decided to buy Cowon AW2 soon, this is how Uninterruptible Power Supply looks like for my future model:

Parking mode is designed to protect us from hits and runs like this:


btw if you would be interested in reviewing Cowon AW2 I should have it around first week of April. You will need to collect/arrange courier and return it from/to West London

I would love the Cowon AW2 but if you think the K1S is expensive the Cowon in UK is very expensive

March 8, 2015 | Unregistered CommenterIan

Hello there !! Congrats on your web page info. it is very helpful !! would you suggest to use a K1S for a sport car ( racing ) and also on a KTM1190 motorcycle ??

1) It's not easy/quick to install or remove.
2) It's not waterproof.

Hi Mat - Thank you for all your reviews. I check in regularly and really appreciate all your efforts. One question I have about this dashcam (as well as others going forward) is whether there is a way to manually mark/move the file for saving from the device itself. For my work I find that I have several events in a 12 hour workday that I want to save, but if I didn't remember to hit the emergency button, the file gets overwritten. Since I can't stop and download the files I need, I find that I have to switch memory cards out before they get overwritten so I can go back later and find the files. Perhaps you could consider looking for that feature in your future reviews.
Keep up the good work!

Great review as always.

Just bought this system and I am eagerly awaiting its delivery. After being rear ended this week and the other driver running to the police to say I hit him head on and then I drove off after hitting him. I will not have this happen to me again. Now fitting other dash cams to our second car and my wife will be getting a helmet cam for when she's on her scooter.

Got to say yes it's a bit more money than other systems but when that accident happens and the other driver tries to lie then they prove their weight in gold.

"the Speedcam database is no use in the UK until the camera can support additional database formats."

It may be worth them communicating with as they regularly update their own speed camera database in many different formats.

See here:

There is an annual subscription fee to download it, but if you find a new speed camera you get it free for a year.

Note: I have no connection with them other than using their database with my Co-Pilot software.

March 15, 2015 | Unregistered CommenterTraction Tim

Yes I bought a subscription just so I could try out their databases with this camera. None of them worked and one actually locked up the device until I replaced it with another database. I've been in touch with the manufacturers about them adding support for additional databases. However at the time of typing there is no support for any other POI databases other than the one that's no use in the UK.

Hi there! Congrats for your excellent job!
I am new in dash cams, I’ve seen all your videos to decide what cam is better for me and my car. Finally I decided that this product (K1S) is perfect for me, as I need in particular a hidden cam. After this, I tried to find about a way to purchase it. There is nowhere. At the end, I found that Koonlung has a Facebook page, and guess what, it has only 28 likes (from 2004 !!!! ???) and one from me 29. There is a post from them includes your comments and video, and it has comment “Now you can buy from us. send email to”. I’ll try to contact them.
