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).

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.

Even better - as the device uses an Ambarella A7 processor, the A7 Firmware Toolkit by Tobi@s seems to work perfectly.

Allows strings editing, AE editing, bitrate editing etc as well as unpacking and repacking the FW.

Bad news looks like the bad audio on the K1S won't be fixed any time soon. The factory recently said:
"We've been testing and improving the audio kit for many times, it doesn't help. Frankly, the sound of K1S is lower than normal dash cam, because the microphone of K1S is installed in the front camera while the 3 meters long front camera cable causes audio signal attenuation."

May 25, 2015 | Unregistered CommenterPier28

Can ( Tec K1S Dual Car Dash Camera ) access the ( ODB-II ) of a car ? like the Lukas LK-7900

May 26, 2015 | Unregistered CommenterSamson

Thats Right About the Sound,
factory still make it that way, My 2nd Unit is current and weaker than the 1st unit
sound recording is real low. 1 or 2 Its Unclear why? my 1st unit was 3-4 out of 10

Review prior Page 8 the Crash Scene Video Posted,
his k1s installed shows a head on collision.
the guy is talking, but could not understand 1 word. Can You? super muffled sound recording is false sense of security.

possible solutions is a $10 mini voice recorder to keep handy. Record lic plates or driver behavior if necessary,
Sound is important to record car information when its too far out of range for the video to pick it up.
It Is Useful Information when combined with the 2 CH Video Feeds. Dash Cams are Generally Used for Peace of Mind, Knowing they have evidence if necessary. Sound Recording also Records the Honking Horns, and Screeching Tires to add to the video if there is a wreck i am guessing here.

The 2 CH Front and Back Video Recording is the Most Important evidence, especially the back cam. For Here in the USA, often a jackass will get within 1 Cars Distance 20 ft going 70mph in a 65 and push you to go 85 or get out of the way.
a Front Cam Only will not get any of what is most important, and miss the rear action.

To Read Front Cam Mobius as Compared to K1S as best solutions is funny. Got Both.
what is there to not like about being able to record the back view, + not have the dvr in the heat and sun, and exposed for visuals.

i got 160 f.2.0 // joovuu got 140 f.2.4 / no one has reported this before that there are 2 type lens available.?
more is not always better, Seems Like i can see 8 lanes of roadway, its quite wide 160

good news is i read on forum message board the MPH is now on the K1S and can be solved with a firmware update.

let us know the process with a step by step performed in easy to understand instructions

Beta Testers to the Rescue. It really does need the support of users to verify & report back what happens before too many try it.

May 27, 2015 | Unregistered CommenterEric Edwards

Took My Own Advice today. Went To ebay/ enter search DIGITAL VOICE RECORDER

my budget was $10. got a usb small device with on and off switch, incl 8g storage for 20 hours of charge and recording is it listing
looks like a usb flash drive, but its a voice recorder.
got it for $9.49 free shipping. This will solve my sound as I keep k1s on Mute / Turned Off.
I dont Want To record Myself driving all the time or passenger conversations is why the sound issue being low and muffled does not bother me that much. When I would care is when its important to record some sounds
You can Use your Cell Phone or mp3 player as in car voice recorder if necessary. uber or taxi needs good conversation recordings

for me i would like the Recording To Come from the Outside Car
maybe 2 channel. inside cabin and outside car, like stereo.
needs to be smart sound where it records inside when necessary and mutes when not, somehow
people that argue and fight all the time while driving or cuss and listen to weird music,
will benefit from and probably like the muffled recording.

May 27, 2015 | Unregistered CommenterEric Edwards

I bought the K1S as per Techmoans great review, but have had one big issue with it. I cannot get any radio reception below 100.0. Not just static, rather totally not there. When I put my hand near the control box (in my glovebox), the reception increases to almost normal rates. For now it is unplugged and I'll have to investigate further.

May 31, 2015 | Unregistered CommenterTyler

@tyler I don't think KoonLung used any EMI coating to keep cost down so it might effect some car radios. You can try moving the power supply further away from the cigarette port via extension cord and also add ferrite cores in the lines. (Cheap on eBay)

May 31, 2015 | Unregistered CommenterPier28

If it makes a difference, I unplugged the hardwired power source so that the unit was running off of its battery, and the radio comes back to life. So this means that the power wire or ground is the culprit. Not sure how to fix it.

May 31, 2015 | Unregistered CommenterTyler

Ferrite cores, as Pier28 said.

I used them on mine and it improved matters but didn't completely eliminate them.

My issues only vanished when I changed to proper shielded aerial cable and moved away from my screen mount DAB aerial to an OEM roof mount one.

You might get lucky by taping up the adaptor with RFI shielding copper tape but the K1S power 'brick' is a very noisy device. It appears to be just a regular 2a micro USB cable so you might be able to swap it out for a higher quality shielded supply.

June 1, 2015 | Unregistered CommenterDave

Alright, so I added ferrite core clamps to each end of the cable. It improved things slightly.

I cannot seem to find a shielded cable with an AC or DC plug on one end. Do the ones with a regular usb plug on one end have the power and ground wires inside too? I've never opened one up.

Hi, just looked at your excellent review of the "new" K1S dual cam, dashcam....and I am impressed seems to tick all the boxes I need, like you I am not bothered with GPS or sound but do want a discreet install with good footage.
However, after downloading your video files I have to say I am not impressed - they seem blocky and have some patterning on them.
Is this a problem with the video files (or maybe my PC ?)......

How does the ACTUAL footage compare with the highly rated Mobius ?


June 4, 2015 | Unregistered CommenterDavidwf

I've just got hold of a K1S today (from vicovation_uk on ebay) & so far the kit looks good. Just bench testing it before it's installed. The firmware it arrived with is R158/20150417 HW_V3 and shows up MPH on screen. I ordered from Vicovation as they had stock the other day on ebay whereas Joovuu are out of stock. Using a class 10 64GB Kingston card and so far it's having no issues with it (the card came supplied & forfilled by Amazon direct, so shouldn't be a dodgy card).

I've found a link on the dashcamtalk forums where R158 can be downloaded from: so hopefully that'll help other UK/US users who prefer MPH.

June 4, 2015 | Unregistered Commentermoojuiceuk

Firmware download instructions.

i notice a few folks discuss the firmware update and link.
see previous page, where techmoan asks dave to shoot the firmware for testing./ Nothing more Since then.

No One, No Where, Discusses it / WHAT TO DO WITH THE DOWNLOAD FILE ? after its on the computer.
please include What can go wrong? what to watch out for, More Importantly What Not To Do?

Anyone that reads dashcam talk will know that doing a firmware update can result in UN-favorable results and can brick the unit

so if anyone has done the update, not just post a link that says there is an update,
Spytech does not give any instructions with that link

June 6, 2015 | Unregistered CommenterEric Edwards

Techmoans Video Links, i noticed the same thing too, and commented here on forum about what i saw in his videos review of the K1S and asked about it. Techmoan response was something about my computer not being able to handle video files, and its true, at the time i had trouble with youtube video, and the flash player. It was Really Jerky Video and Crash Reports etc

I reviewed again Techmoan Video with a Newer System and see some issues with his videos still. You Only Notice this if you have Big Screen HD Definitions and Look Closely to Fine Details. otherwise you will not see what is being described, if you see the video as a joy. I find it Depends on How Well You Look And Evaluate Details. i am super picky and critical, so i see what your seeing too!

My Video using the K1S when Viewed on Computer from chip is better than what you see, Do Not Worry!

what i read is overwhelming support in saying the Video Quality Is Good
i give it 8 out of 10 stars.

I have a Mobius, its an excellent choice, and great video at about $75 US
software is impressive to program the menu, plus you can change the lens or add the 6 " camera ribbon lead to detach the lens.
its small in size and price and has a nice soft plastic feel to it.
you can do a front and back set up easy with the mobius, many on dashcam talk say its a great option to consider

with DVR Not Exposed to Heat or People Seeing The Big Ugly Suctions Cup Type Device.
Its a Little More Stealthy to say the least

something is better than nothing, if the mobius makes more sense

June 6, 2015 | Unregistered CommenterEric Edwards

Mobius also has an unprecedented following on Google / forum.....everyone comments on the quality of footage both day and night time.
I only want to buy this once and would really like to see some decent footage without the black speckles that are on Techmoans examples.
The spec of my PC way exceeds anything required to play these clips....and yes, I really would like to go ahead and purchase the K1S.... but not until I am convinced !

Not sure why my screen module beeps every once in a while, like 10 minutes or so. I have the G sensor turned off. Radio reception is still horrible. Looking for that shielded wire still, or atleast copper tape.

June 7, 2015 | Unregistered CommenterTyler

hey tyler that beep every so often is letting you know of the next scene recording track/

select the minutes in the menu. i remember hearing that beeping thing going off regularly.
Sound can Be Turned Off /to not hear Any Beeps

that g-sensor is sensitive too, it makes beeps and yellow ! mark files with bumps in the road. Turn it off too
I dont Hear Any Beeps Now so happy too!

in UK they drive with this thing beeping while they come across street cam alerts
probably duct tape or use wire ties to attach the dvr to dash to see it up front, it displays some sort of info for them

Here in the USA
its best to put the dvr in glovebox out of reach or even being seen.

the LCD Screen is only good for doing a camera alignment and program the menu, not as a video camera monitor
use the micro chip in usb adapter to really see the video up close.

For Me its Set it and Forget It, and hope the video is there if i need it.

June 8, 2015 | Unregistered CommenterEric Edwards

I purchased a K1S and installed it into a Range Rover Sport. Front Cam sits in front of the mirror and can hardly be seen, the rear is behind privacy glass so likewise. The unit sits in the glovebox and I've linked it to the SatNav screen so that I can see either Front Or Rear of Both. I have it set to rear, so can be used as a reversing cam or for checking on trailer loads.
It has access to Speed Camera POIs, though they are somewhat random in that some it ignores and some it pops up with a warning beep, shows your speed and if above posted limit, continues to beep. Would be useful if it were up to date.
Its been working fine but the other day I set off and nothing happened - no voice saying recording started, nothing on the screen and nor on the unit. Pressing reset cleared that and its been working fine since (it didn't lose its settings).
Mine was supplied with MPH.
Overall I'm happy with it and whilst I'm sure its not cinema quality, sufficient for what its designed for.

Hi Mat,
Great review, thank you!
1-Do I need to worry about purchasing this ad-on: Blackvue Power Magic Pro Vehicle Battery Discharge Prevention for Parking Mode?
2-Does the GPS feature sort of act as a radar detector?
3-What's the deal with buffering in parking mode? Is it important that it doesn't record a few seconds before/after like other cameras do?

June 10, 2015 | Unregistered CommenterMichelle

Can i use ( power magic pro) with K1S.

June 13, 2015 | Unregistered CommenterSamson

So I ordered this camera setup from Amazon. I got the Spytech K1S dual Car Dash Camera and I love the camera but I'm running into an issue. I have it plugged into the 12V port (I didn't hard wire it) and the Park mode is off so it doesn't kill the battery. What I'm finding is that the unit keeps recording after I have shut the car off and removed the keys regardless. On top of that, I have to hit the record button every time I want to start recording. So I guess I have two questions. Is there an obvious reason I'm not seeing as to why the unit doesn't shut when I shut the car and do you need to hit record on the unit before driving anywhere if you want to record? The other dash cams I have used all shut off by the key switch and all start recording when the key switch is turned on. Thanks for any help.


June 13, 2015 | Unregistered CommenterK1Suser

Check 12 Volt Plug,
have you confirmed no juice to your plug?
another check method after you turn off the car,
simply remove the 12v adapter after you remove the key
Does it still go? cause it should not at this point because you verified no juice to the plug, and your Parking Mode is OFF
i too have a k1s, since they came out, and know some about it
No Need to Press Record each time,
same as your other dashcam, records automatically when you start the car
you might need to exchange it since you " love it " and find a good working unit

June 14, 2015 | Unregistered CommenterEric Edwards

Hi all,

I've just installed my K1S and was wondering if anyone had any tips about the best settings to capture the best quality video.
I know it's subjective, but there are probably some common 'good' settings.

Cheers all.

June 14, 2015 | Unregistered Commenterpafer

Great review nice dash cam but expensive.
A good idea would be a dash cam that records when car is parked but sends the video direct to icloud or your computer.
Perhaps a system with tracker as well.
Mybe records records when car alarm goes of ect.
Nust ideas pehaps they already exist.

June 16, 2015 | Unregistered CommenterDave

I've owned my K1s for 2 weeks now and have been following the forum discussion with interest since Installing the device into my car.
I thought I would share with you my experience with this camera and hopefully help anybody who is having any issues with their unit.

I'm a taxi driver, so my unit is probably working harder and longer than most peoples, with continual power ups/downs throughout the day, and the sheer number of hours spent recording.

I initially decided to go with a 64gig Kingston class 10,SDXC "UHS 3" card, about as quick as you can get I believe.
Upon first boot all seemed fine but after a while I experienced a lock up, and a refusal to power down, with the unit repeatedly telling me "recording stopped" over and over again.The only way I could stop this was by actually removing the battery and restarting it.
It wasn't a continual issue' but it did happen once or twice. The most annoying thing though was the unit telling me at random intervals that the "GPS was ready". It would do this constantly throughout the day at approximately 10 to 15 minute intervals.
I initially thought that it must be the GPS losing and regaining connection but after checking I noticed that the GPS light remained constant even when the unit was telling me otherwise, very weird.
The rest of the functions seemed to work OK, although I didn't bother with the lane change/collision detection or speed camera nonsense, so I cant comment on that.
It was very strange, my unit would be fine for a whole day then I would get up in the morning only to fine it wouldn't boot or would lock up.
I did buy a UK unit from an official UK distributor so I have a proper warranty etc, but I thought I would eliminate everything thing first before going through the hassle of returning it.

The first thing I did was check my wiring, making sure none of the wires were kinked or stressed, they weren't.
My unit is hard wired into my vehicles fuse box into a circuit that comes on with the ignition. I wondered if my unit was receiving enough stable power, so checked the circuit with my multimeter with all the lights on, the electric power steering being moved and every thing else I could think of that draws from the battery, again all was fine so that eliminated any power issues.

So, I was happy that it was wired in and mounted correctly, the only thing I hadn't yet tried was a different memory card.
The card I bought was a genuine product from a proper dealer so I had no worries about it being a fake, but I was using a Class 10 "UHS 3" card and wondered what the difference was over a standard class 10. So I paid a visit to the SD Associations web site..

I wondered if there was some kind of compatibility issue using a "UHS 3" speed card with the K1s, after all, it only mentions the the need for a Class 10 card and according to the SD Associations site there may be some issues using UHS 3 rated cards in devices not specifically designed for them. So, back to the shop to purchase another card, this time a standard Sandisk 64gig Class 10 SDXC.

Things seemed a lot better at first, no more lock ups, all footage seamlessly recording from both cameras to the card. Hooray I thought, problem solved, but after a while I started to get the continual "GPS Ready" message. I then realised that this was only starting to happen once the card was full and data was beginning to be over written and looped. This convinced me that this units woes were somehow related to memory card issues.
I then noticed techmoans comment about a lot of devices like these not liking cards over 32gig, due to a difference in the way they are manufactured.
So, back to the shop once again (good job I can put all these cards to good use in other devices I own). Another standard Sandisk Class 10 SDHC (non UHS) card was purchased but this time in 32gig guise.

Since using this card everything is working perfectly, and has been now for over a week, with about 10 hours a day usage.
No more lockups, rebooting, strange repeating messages or refusals to start recording. My unit is working flawlessly.
I'm not necessarily suggesting that this is what is causing everyone's issues, but its my belief that this unit is very card fussy, especially cards over 32gig.

Another issue I noticed was that when I reviewed any footage using "RegistratorViewer" , the red line that traces your route on the map was broken up and segmented, I'd put this down to something to do with the "GPS Ready" error I had before, but unfortunately I still had the same problem using the new smaller card. However, after popping over to "RegistratorViewers" web site and downloading the latest version of "RV" (V6.0) all is good and working fine.

I hope I haven't gone on to long, but I just hoped that my experiences may be helpful to anyone else who is having issues with this awesome little camera.

Kind Regards,

June 17, 2015 | Unregistered CommenterSuffolk Bob

great you discovered what works and what does not work with the K1S

USING A 32G CARD is highly recommended as a solutions if your having recording issues.
in your post you mention it works great now! / Techmoan also mentions this in the forum and recommends 32g
took a couple weeks for me to sort out recording issues, trying cheap cards off ebay

the GPS notice coming on and off is functioning, When there is a Lost GPS Signal, your footage shows red line breaks on the viewer confirms this theory. Your Loosing GPS Signal
Place the Module in another Locations
its long lead allows re-position. Try That, should stop the GPS ready Notice

also good to check from time to time verify all is well as cards can wear out with taxi or heavy demand use
2 video streams to 1 micro card is unique and not easy to accomplish is why the right card is must have
UHS-1 / 32G / name brand no generics or fakes Transcend Prem -Lexar633 - San Disk Ultra

let us know if you sort it out, and what more you discover

June 17, 2015 | Unregistered CommenterEric Edwards

Hi Eric,

The repeated "GPS Ready" messages showed no correlation to the broken and segmented tracking lines viewed on RegistratorViewer, either in location, frequency, duration or number. The green satellite symbol on the K1s's screen always remained illuminated and steady, showing no loss of satellite connection at any time.
Also, files recorded during the periods that I was getting the constant "GPS Ready" messages, that had previously showed gaps and segmented tracking lines now show no such issues when being viewed using the newer updated version of "RegistratorViewer".

This shows that the GPS data was actually being captured just fine, proving no loss of satellite connection.
It also shows me that my old version of RV had an issue that has since been sorted in version 6.0.

The constant "GPS Ready" messages must have simply been the unit malfunctioning.
Since the issue completely disappeared the instant I started to use the smaller card it makes me start to think that the 64gig cards I used were somehow causing other issues other than just simple recording problems with my unit.

Either way, all is fine now.
