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

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.

@Karel - if you have access to a multimeter, it might be worth checking to ensure your alternator is putting out enough voltage for the unit to work with. A healthy alternator should put out between 13.7-14.5v when the engine is running. If yours is putting out anything less than 13v with the engine running, then you might have an issue.

As consumers are switched on, the voltage could drop to a level that the camera is fussy about. Stuff like EPAS (electrical power assisted steering) can consume lots of power, meaning that issues such as this can rear their heads.

Of course, it could also be a fault with the K1S but as you say it works fine on battery, that sounds like a supply issue more than anything else.

If you enable parking mode, does the unit continue to work? It should - when it detects the power loss (or drop below its comfortable voltage) switch over to the battery. If it does it, this could confirm or deny a supply issue. Worth a try anyway!

to all K1S owners that have a mac , the datakam software is avalible here (as well as newer versions 6.0 for windows seems to stabilize the heading over 5.8 (whats included) would jump around alot on the heading)


April 29, 2015 | Unregistered CommenterNicholas S.


Joovuu will be shipping in the UK soon

SpyTecinc from USA New York also ships internationally and has this in stock today

Also, Amazon has TWO options when you buy something. Fulfilled by Amazon (FBA/Prime) and Fulfilled by Merchant. The default is FBA and they won't ship internationally for electronics. Click the "3 new from" small hyperlink on the listing, and choose Spy Tec's other non FBA listing.

Another Test Coming Soon, got 2m lengths of Micro USB Leads from ebay on the way. want to know " how far cams go " from the DVR and still record clear video. this would be good to know for large Vehicles or RV. Will Report Back how many sections of leads, can be connected in series. Another Test will attempt to Remove the Glue on Lens Threads, and Manual Adjust FOV, see if i can get sharper focus further away. any body else with Tips Tricks and Install Help on the K1S let others know

April 29, 2015 | Unregistered CommenterEric Edwards

I've just tested the new Datakam Player as linked by @Nicholas S and it has a KMH/MPH switch in it, so although KMH is overlaid on the video, the speed readout on the player is displayed in MPH.

To set it, select the View menu, then Measurement, and British System (feet, miles).

spytech says 90 days, no card installed, and gps thats optional +20.
what other retailers got this in the USA? you guys got me interested in this thing, but dont know much about it.

April 29, 2015 | Unregistered CommenterBlake K.

I got Mine on Amazon couple weeks ago, after seeing the review.

Spytech was Back Ordered on Website, but it showed up on the Amazon Site. so i got the K1S,
but it did not come from spytech.
It Came From Roadcam Dan. He sent it out Fast and had SD Card in it.
Going to have my Husband install it for Mothers Day Gift, for myself and our children. Bless His Heart.

April 29, 2015 | Unregistered CommenterSusan S.

I ordered the K1S (w/GPS) from SpyTec on 19MAR2015 through Amazon and received it on 22MAR2015. The first control box was defective. It would reboot constantly and every 30sec or so, it would go into Alert mode. I contacted SpyTec and they replaced the control box without issue.

The K1S, IMO, is the best out there 'today'. I had been using Techmoan's reviews, but when I heard him say it was his 'favorite' dual cam setup, that sold it for me. The VQ is quite good. The audio, well, I can hear everything (road noise, me, my stereo, etc...). Along with the replacement box, I was also loaded with an April 2015 firmware, so, it "might" be that they fixed it. I don't know.
My menu setup is fairly generic: LDWS-off; G-sensor off; FCWS-off; LCD Screen Off-3min; using Lexar 128GB micro SDXC; hard wired to IGN fuse. All wires hidden, tucked and secured. No issues with EMI. Camera see's right through heavy tinted ceramic window tint.

I tried Park mode once, and really, the thing just ran for about 30min before the battery died. I guess it could be useful in a crowded parking lot. I really like the GPS and speed indicators. Our small county in Georgia loves to generate revenue.

May 1, 2015 | Unregistered CommenterImpliedConsent

ImpliedConsent, it would be good if we can keep track of the firmware versions released for the K1S.

chris (earlier post) had "K1s:R0124/20140922 HW_V1".

techmoan had "K1s:R140/20141204 HW_V1".

What is the version number of the firmware you received?

May 2, 2015 | Unregistered CommenterMoschops

@Moschops: I bought mine from JooVuu and have K1S: R157 / 20150320 HW_V3

May 2, 2015 | Unregistered CommenterDave

Like Matt, I've been looking for a dual camera DVR for ages and thought that this was the ideal one. So, as it's not available in the UK, I bought it from the USA via Amazon.

Perhaps I've been unlucky but the unit wouldn't work correctly from the start. After installing the K1S carefully and securely, the unit stalled on my first journey and wouldn't stop bleeping. For all subsequent journeys I've had to press the reset button every time to get it to record, as the unit shuts down automatically and stops recording when I start the engine, even though you can still see pictures from the cameras.

The front camera port or connector was also faulty and would cause the recording to stop and restart of its own accord.

The Amazon supplier (Roadcam, Inc.) and Koonlung themselves have been very helpful in trying to solve the problems but I've spent many hours this last month sending emails, trying things out, and uploading clips for analysis that I've decided to draw a line under the experience. I posted it back to the USA today.

May 2, 2015 | Unregistered CommenterAdrian

Can anyone advise me how to update the firmware.

Is there a website for updating it?

May 2, 2015 | Unregistered Commenterchris

I've tried uploading some pics of my install to demonstrate how discreet the unit can be, I did strip down some panels in the car to get it done but I enjoy little projects like this. The unit is paired to my car screen just for the sake of it!

May 2, 2015 | Unregistered CommenterIdris Patel

Excellent setup there Idris for pairing up to your in-car screen. If K1S can fix the soft audio problem, better quality control on that front cam connection, and improve on video quality (especially night video), then they have a winner.

May 3, 2015 | Unregistered Commenterefoo

@chris, Koonlung's website does have firmware updates for some of their older products (A7 & C81). In theory, if Koonlung were to make K1S firmware updates available, then yes.

So far we have 4 firmware versions:
K1S:R124/20140922 HW_V1, chris
K1S:R140/20141204 HW_V1, techmoan,
K1S:R157/20150320 HW_V3, Dave,
ImpliedConsent (April 2015)

What interests me most is techmoan and yourself seem to have a different hardware version, HW_V1, to dave who has HW_V3.

It would be helpfully when people post their experiences/problems with the K1S that they include their firmware version. That way we may be able to attribute a particular problem being fixed by a particular firmware version, e.g. it looks like the extremely quiet audio has been fixed in/by the April 2015 firmware (see ImpliedConsent’s earlier post).

May 3, 2015 | Unregistered CommenterMoschops

Chris - whilst I was trying to sort out the problems I had with the K1S, I was in contact with Koonlung directly and they were able to send me a zip file of updated firmware. Try <>

May 3, 2015 | Unregistered CommenterMoschops

I'm guessing everyone that bought the first batch has hardware HW_V1, and this newest hardware version HW_V3 + firmware has better audio. If I was a customer of HW_V1 with bad audio, I'd ask your seller to exchange it for HW_V3.

May 3, 2015 | Unregistered CommenterPier28

The HW_V3 audio isn't any better in all honesty, so I wouldn't be rushing to suppliers just yet.

I've also had a few documented issues with mine, so I'm not sure what has changed in the revision between V1 and V3, I wouldn't be surprised if it's just down to reworking after issues with component suppliers, rather than fixing issues present on earlier models.

That is all supposition though, I don't have any actual, viable evidence.

May 3, 2015 | Unregistered CommenterDave

The damn thing has started stopping and starting the recording again now, I've been driving with the glovebox open to keep half an eye on it, and it will occasionally play a tone (the same one from before), the red 'recording' dot will disappear and it will sit like that for a couple of seconds before the shrill recording beep sounds, and it starts recording.

I've tried this with the GPS disabled (but not unplugged) and it does the same thing. It can't be the g-sensor either as this was happening while standing still.

Tellingly, it was in the process of a camera alert when it happened, and the camera alert screen (the one that shows your speed, the road speed and the distance and type of camera) remained stuck on the screen, not updating at all, showing that I was doing 0km/h in a 50km/h limit, 0m away from the camera.

It only changed when I manually interrupted the recording and tried to go into the menu system (which worked).

Hopefully Koonlung get some updated FW on general release soon that fixes daft issues like this...

May 4, 2015 | Unregistered CommenterDave

How to mute (turn off the microphone)? I can't find in on the manual, or in the system. Thanks

May 4, 2015 | Unregistered CommenterJames Bill

I found that I had the same issues with the start stop recording problems that some of you have. I think that some of the recording issues might be because of the SD card. i used a class 10 Sandisk 64 gb but when I switched to a 32 gb all the recording issues disappeared. If you watch the screen you will see that it might say Card fragment error or Low Speed Card and stop and start recording. The card can't handle the recording so shuts off to catch up.

May 5, 2015 | Unregistered CommenterMing

BTW, I've seen in other dashcam posts that the not all SD cards are created equal and that the Sandisk is often the problem. Try switching to another brand of SD card 32 gb and see what happens.

May 5, 2015 | Unregistered CommenterMing

Hi all, I've contacted Koonlung with the interest of becoming the sole distributor in the UK. The reason why they can't sell to UK retailers is because there aren't any distributors here! What would the demand be like here for K1S cameras? Let me know!

May 5, 2015 | Unregistered CommenterKelvin Z.

James. Press the middle button with the picture of a microphone.

May 5, 2015 | Registered CommenterTechmoan

Yes I'd never recommend going beyond a 32GB card. 64GB cards cause issues with a *lot* of different cameras. I think the specs must be slightly different.

May 5, 2015 | Registered CommenterTechmoan

If a person wants to be on the extra safe side, someone somewhere on the interweb recommends using a class 10 UHS-1 SD card, which is supposed to have a different bus and is faster. I am using a 32GB UHS-1 and have had no problem with it being able to handle the two 1080p feeds.
I believe others have had success with using a normal class 10 as well.

May 5, 2015 | Unregistered CommenterBrett

Someone Somewhere recommends UHS-1, here too on techmoan
without use // expect issues and problems. generics and fakes. guaranteed problems and recording issues with flipping cam video, stop and start. g-sensor sets off the recording many times with bumps in the road another factor. Try O, dont need it. Use Event Button
Appears More Is Not Better with Card Size / Thanks Techmoan for that advice TO USE LESS THAN 32 G.
I use 16 G Lexar 633x NO ISSUES NOW. before there was.

got a 2nd K1S this week from US Ebay Link above $239.95 Free S/H 1 Year Warranty. included SD Card from RoadCam
Firmware: R157/20150320HW-V3 Latest Out. I have the 1st Version from a Lot of 10 in the US. will check that firmware number from original release. Will Compare the two units see whats different. Also I got the USB Leads in and did a test. Added 2 6ft Length in series to test Will It Work? Does It Shoot Video 21 Ft on the Rear Cam? Will Post the Test Results Shortly. info for RV and Large Vehicles, find out : How Far Can You Go With the USB Leads and Record Video
