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.

I have ordered one from Joovuu, took all day as the website kept crashing, when I did order it showed free shipping but still charged me the £3.45 for second class shipping, so I spent another .40p and had it sent first class.
Hope someone else can get the free shipping working, maybe they were having a bad day,
I ordered a 32gb Integral Class 10 UHS-1 for £10.79 using code INT10 at checkout at MyMemory.

Glad to Hear Folks are Starting To Realize what is the Best Dash Cam Out There

Currently, for 2015.

If Techmoan Uses it Today,
and got another one for his 2nd Car, Ummmh i wonder which dash cam is right for me.

DashCam Talk Got it going on.
Visit the Website, see " other" on the lower page, below all the 75 other Dash Cams, Its on The Bottom,
i guess has to work its way up.
But It Is There. See K1S Koonlung, Techmoan Matt Favorite Dash Cam,

Read from all your Friends. They are Already There Talking About it,
Niko Had A Great Idea, You have to go there to read it.

That $199.98 Price from SpyTech, Does Not Include the GPS or Event Button

The Total Package is More, Check Website, Its " BackOrdered " in small print. Its Been Like That for 3 Weeks. You Guys are not getting any time soon from spytech, See For Yourself. Go To the Website. Read the Small Print, it is in red.

April 8, 2015 | Unregistered CommenterEric Edwards

Its Not In Red.

" Its On Back Order "
Says Today in Gray Text on SpyTech Website

i guess so you dont notice it so much

April 8, 2015 | Unregistered CommenterEric Edwards

Dear Techmoan:

i watched your K1s Review Again for a 2nd Time Around today
maybe i missed something

The Video Quality, you driving around Town, etc I see Stuttering Video
where the image goes Da Da Da Da Da, as in a $79 dashcam

also same thing i notice on mine is Glare/ from the Shinny Dash.
notice that if your looking at it instead of the cars you see Super Glare form
New Cars, and that Shinny Spray Stuff. i bet the old fashion dash mats
remember those:? would cut the glare. i too have similar issue

all i know is when i view Video off the SD Card/'Adapter/ it is Perfectly Smooth Video Playback
"youtube doing that"?

or is that what you really got.


Seems Like you Got A New Car, a week ago, but no one knows what kind yet
did you put the K1S in it?

April 9, 2015 | Unregistered CommenterEric Edwards

There's no stuttering with this camera - so you have an issue at your end. 1080p youtube flash video playback can be too much for a lot of computers. Download some samples and try those out.

Reflective dashboards are more to do with the angle of the windscreen than anything else. Some cars reflect, others don't. Unless you are putting a K1S in a 2006 Smart Roadster Coupe, you can expect to get different results.

Yes I've got a K1S in both cars now and just checked the footage after a month of driving and it's still working perfectly.

April 9, 2015 | Registered CommenterTechmoan

right again techmoan:

i have been recently seeing " shockwave crash " on the firefox, and flash player not found
etc, acting funny and buggy, not all the time, some times

youtube uses flash and the two are connected.
Latest Version #16 seems to be issue,

It Might Not Be The Computer

"It Could Be the Crappy Adobe Shockwave Flash Player" acting up
i googled it and it appears common with many others, saying the same thing about this buggy player

April 10, 2015 | Unregistered CommenterEric Edwards

Looks like a pretty snazzy cam.. might be my next upgrade if my current one fails

April 10, 2015 | Unregistered CommenterTobbe

Mine has arrived today from Joovuu, so hopefully I'll get it fitted up and operating with the PGPSW camera DB. Happy days!

April 10, 2015 | Unregistered CommenterDave

@Dave, let us know how you get on with install as well as the DB.

April 10, 2015 | Unregistered CommenterRiggers

I've thrown together a clunky bit of Python (3.4.3) to convert the PGPSW database into Navitel speedcam.txt format.

It takes into consideration the change between MPH and KMH, and has support for the directions that the PGPSW DB shows. There are optimisations that will need to be done, I am personally a bit unsure about the directional cameras as the Navitel support info shows exact degrees, whereas PGPSW is compass-based. It may be that the directions don't work unless you're bang on the heading that the Navitel DB says you should be, if so - the directions can be removed and it will (should) alert just on proximity.

If anyone wants to tinker with it, feel free - I've chucked it up on pastebin. Makes a change going open source! :)

One thing that is worth mentioning, if you're using any of the other PGPSW CSV databases, replace the name on line 37.

A caveat: I don't have the time to support anyone's use of the script though, so if you use it and it doesn't work for you, then feel free to correct my code but I won't be able to reply individually to any issues.

Hopefully I'll get the cam installed in the next few days and will report back with my findings.


April 10, 2015 | Unregistered CommenterDave

One last thing - I've only just noticed on the pastebin, the line:

from enum import Enum

can be removed as I went to dictionaries instead of enums and, as I pasted it anonymously - I can't edit the paste!!

I purchased this DVR from Spy Tec via Amazon and have been using it for a couple weeks. I have it configured for one minute clips and the memory card is a new Samsung 64GB EVO Class 10 Micro SDXC, which I configured in the device. I think the unit is great and it's exactly what I've been waiting for in a dash cam, but I'm having a serious issue with it. After it records somewhere around 135 clips all the subsequent files have thumbnails with a blank white background and bold red type through the middle saying "Invalid." On my computer the "Invalid" files are the appropriate data size, and are listed as .MP4 files, but they are not recognized as video files by any viewing software. Has anyone experienced anything similar, or have any idea what the problem might be. After spending a couple hours routing cables in my car I would hate to have to return it. Thanks!

April 11, 2015 | Unregistered CommenterJeff



should say korea on back, if it says taiwan?
You Might Have a Fake. and it wont work.

i got one on ebay,

they dont work in the K1s
tried it

I HAD SAME ISSUES and worse,
cam1 and cam2 flipping video feed, and missing sections of clips

Tried Several Generic SD cards

Found // LEXAR 633 (gopro approved)
now its good

try to experiement with only High Quality UH-1 (ultra high)
class 10 alone is not enough.

ITS A UNIQUE 2 Cam Dual Lens setup into 1 Card

before you tear your wires out, try different cards, helped me, and now its good

April 11, 2015 | Unregistered CommenterEric Edwards

As you suspected, the Samsung chip is indeed stamped Taiwan in the back, not Korea. Strange since I purchased it from Amazon with the DVR, and not from some shady third-party off Ebay. That being said, I just tested it with CrystalDiskMark 3.0.4 and it does read/write better than 80MB/s, so it's fast although this doesn't necessarily prove authenticity. At this point I'm going to quickly purchase another chip to try before pulling the plug on the unit, but the 30 day return window is closing fast! Thanks.

Amazon and Ebay Sell Fakes

they have been doing it for awhile

Techmoan mentions it
as a precaution to take in his posts



read hundreds of customers saying how they got burned,
and did not know it, until they read about it on Forums Boards discussing this topic

THE COPIES LOOK EXACT! cant tell the difference, packaging is perfect copy.
your dealing with professionals, know what they are doing

Needs to Say Korea, per Samsung Alert,
and what i read online,

Do Your Own Research To Confirm

most say they got it on Amazon or Ebay

ITS A FAKE FOR SURE what you got!
even samsung says check the back


"you have had the same thing happen to me, but i purchased my card online
came with a sony card, but ended up using it in a sony camcorder,
and tried generics 1st cause they were laying around

Tried 4 Generic Cheap SD micro cards, they record, but its buggy big time

that spy tech should include a Real Card Not A Fake, or provide instructions on how important the card you use actually is
THE CARD IS THE RECORDER, when you think about it

Your one of his 1st customers from a group of 30 to get the early release

Count Yourself Lucky,



otherwise / wont work properly,
size does not matter as much. 32 to 64 g is all you need
I use only 16 g Lexar 633, a bit pricey / highly rated

the recording that you see thus far

also if you got any install tips or photos
visit dashcam talk

there is a special forum for users
/ K1s Koonlung Listed under " other "

Its Listed Correctly Being " OTHER "
as there is Nothing Else Like It

April 11, 2015 | Unregistered CommenterEric Edwards

I've fitted the camera today and there are some good points, but also some quite significant bad points.


Very discreet, really only visible if you know what you're looking for
Speed cameras do work in the UK with the PGPSW db, however I'm going to have to do some work on the script as it's not quite there yet.
Daytime image quality is superb, from both front and back cameras. Really happy with it in the daytime.


Build quality is a bit dubious - while fitting the emergency record button, it stopped clicking. I'm going to have to dismantle it to see if I can figure out why, but this shouldn't happen out of the box.
Night time image quality leaves quite a bit to be desired, forget about freeze framing either the front or rear cameras to get a reg number at night - it isn't going to happen. The only time they're visible at night is when they're right beside the car and you aren't moving.
The initial settings are ignored by the camera - I had the speed stamp saying 'off' on the camera, however it still recorded the speed. I had to turn it right down to 20kph in order for it to honour hiding the speed stamp. Maybe this is just me and 'off' means 'on all the time rather than off above a set speed' but it's still a valid point. Park mode was set to 'off' as well, and it merrily kept recording in park mode until I turned it on and back off again.
The beeps and bongs made from the unit are LOUD, but the speed cam warnings can be missed as they are a little bit on the quiet side. I'm going to experiment with the GPS antenna/speaker to see if I can site it a bit better or ensure it stays where I put it.
This may just be my car, but at night, the autofocus seems to latch on to the dash top or dash display rather than what is out of the window. I'm gonna have a bit play around to ensure that the cameras are positioned as accurately as I can, so this is technically a bit of an unfair criticism and it's probably more my car than the camera.

All in, am I happy with the unit - yes, definitely. OK, so night performance leaves a lot to be desired but in terms of what it does, how discreet it is and the fact that it has only been in the car for a few hours - I'd give it a solid 8/10.

I'll try and get some photos of the setup tomorrow, and I'm going to tinker on with the PGPSW db script as I now know how the camera operates, so fingers crossed once I've had a bit of playtime with the device, I'll be in a much better position to give pointers to other purchasers of the device.

April 11, 2015 | Unregistered CommenterDave

One thing I did notice, is that the speed cam alerts tend to only fire if you are bang on the heading it wants you to be on - so as part of the testing, I've updated the script to drop the directional alerts. It now works like an oldskool detector, alerting whenever you're close to a camera.

Understandably this may hack a few people off, but until I can find a more accurate method, it'll have to do for now.

Also, as the device speaks the camera type to you, I've rolled up all of the different types of camera on the PGPSW db into "speed camera", "mobile camera" or "speed limit" for SPECS. This was determined from the Navitel support site here:

The updated PGPSW-Natitel script is here: (v0.2)

April 11, 2015 | Unregistered CommenterDave

you got a Bonus Using that Speed Cam Alerts in the UK

we don't have that feature


regarding the " DARK NIGHT VIDEO

mine too was on the dark side even during the day
I BUMPED UP THE AE BIAS to .3 and to .7 and see improvements
1.0 is too much

play around with this setting
its in the menu settings.
AE BIAS (bump it up)

also you will see SCENE SETTINGS
there are 18 .
these too change the video how it looks

see what works best for you

funny how they have fireworks as a setting

April 12, 2015 | Unregistered CommenterEric Edwards

Thanks Dave for your feedback. I currently have a Mini 0801 dash cam and its night video is only mediocre. My next dash cam purchase must have better night video than the 0801, and it is a bit disappointing to hear this K1S's night video is not that good either.

April 12, 2015 | Unregistered Commenterefoo

I now have the K1S installed, I am impressed with the quality of the night video in comparison to what else I have seen, which is not many, I admit, but I can see colour, which is an improvment on what I have had in the past.
My front camera has been acting up a bit, I think it is probably a bad connection, but it has been ok for the past two days, so we will see.
I have a 32gb card which filled up in about 35 minutes on the superfine setting, at least on the inside night test I ran.
It is not a fake, I ran the excellent h2testw program to test it.
The battery lasted 34 minutes from full charge with GPS and both cameras running.
Only cons so far, aside from the glitchy front camera, is that it would be nice to have an 'audio off' setting, and the cables for the GPS and the front camera are a bit shorter than what I need to run it where and how I want. But that is just me.
Dave, I would be interested in knowing how I install s POI file. If you are wondering what I need to know, please just think of me as an idiot and start from there.
Overall I am pleased with the K1S.

April 12, 2015 | Unregistered CommenterBrett

Brett - there is an audio off setting, tap the up arrow button when not in the menus and you'll see the mic icon appear with a line through it.

As for the POI, it depends on what the POI data is to start with. You could load it up as a camera file using camera type 106 (another danger) to alert you, but it isn't a navigator so-to-speak, it's just really a proximity alerter.

April 12, 2015 | Unregistered CommenterDave

@Dave Thanks for that Dave, I will turn off the mic later.
I have looked at your script, and I admit that I have no idea how to apply that to a list of POI's, where ever I may get them from. I have access to quite a few different POI texts, but then my eyes kind of glaze over. I will search the interweb for a how to later this evening. Thanks.

April 12, 2015 | Unregistered CommenterBrett

Ah right, I get you now - that script is bespoke for the PocketGPSWorld speed cam db only, any other POI databases probably won't work as they won't be in the same input format.

You have to subscribe to PocketGPSWorld in order to obtain their speed cam database and make sure it is downloaded in Other (.csv) format, then run it through the script using Python 3.4.3. That will spit out a GPSDB.txt file which you drop onto the K1S' SD card from the PC, refit it into the K1S and go for a drive.

I'm still testing though so unless you're handy at Python etc and can fix any mistakes I've made, I'd not recommend signing up for the PGPSW DB just off the back of this, at least not until I've tested and tweaked a bit more (or someone comes along and submits a modified script that just works!)

April 12, 2015 | Unregistered CommenterDave

After doing a bit more testing today, I've made a few more changes to the speed cam script. v0.3 is available on pastebin at the url below if anyone wants to have a play with it.
