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%!

SJ2000 Helmet Cam - Letting the family down

Chad McQueen, Don Swayze, Frank Stallone....sometimes it's hard to live up to a family name and the SJ2000 is no exception. The SJ1000 is a popular cheap action camera that punches well above it's weight, so you'd assume that if you transplanted it's innards into a metal waterproof tube then you would be onto a winner. It seems that it's not quite that easy...

When I realised that the SJ2000 wasn't a camera that I could recommend I decided to rush this video out quickly before the end of 2013, rather than kick off the new year with a disappointment. 

Here are the Buying Links (but I'd suggest you look at the SJ1000 instead).

Hey Matt, thanks for a year full of interesting, addictive reviews!
Pitty for the SJ2000!
Maybe that one

is a more worthy sj1000 "next generation"?

Happy New Year!

December 29, 2013 | Unregistered CommenterChristos

There are so many similar cameras out now. I will be looking at the SJ4000 in a few weeks, but this is a bad time of year to try reviewing action cameras. I waited over a month before I could get a fine day to take the motorbike out.

December 30, 2013 | Registered CommenterTechmoan

Which sj4000? The gopro clone or the Sj1000 one??

December 30, 2013 | Unregistered CommenterMAtt

Thanks for the review, disappointing indeed, seems like something they could fix with a firmware update though ?

That CVWL-I390 looks interesting with its (apparent) live feed to iOS/Android, hope it can be used to review the clips too, not just view them live like on the Sony AS15/AS30.

December 30, 2013 | Unregistered Commenterwebvan

Interesting review!
I am considering to buy the SJ3000, because it has a remote control. The images looks very nice! Would you advice me the SJ3000 or another camera with a remote control? Or should I spend some more money and buy the Sony (because it has 120fps)? I don't know it yet...
Thanks for the reviews!

December 30, 2013 | Unregistered CommenterGerben

First of all I would like to say happy new year. SJ2000 looks so bad then 1000 but other two models looks nice SJ3000 and SJ4000. They are not bad. I am intresting with SJ4000 cause its looks like to Gopro and I think its compatible with gopro accessory. Could you review this models?


January 2, 2014 | Unregistered CommenterBulent

I think the SJ4000 has the same problem with direct sunlight. It uses the same chipset as the G1W, and this test video hold me back from buying it. I hope you get a newer firmware! It could be the first cheap camera with great mounting options and a waterproof case.

Are you going to review the SJ3000? Based on this youtube clip it doesn't have the same problem, and it can be mounted on the side of a motorcycle helmet.

Thanks for all of your reviews, I really enjoy them!

I asked for Christmas a GoPro (joke) or Mobius or SJ1000 or SJ4000 because I can't decide. Then I found a Hero3+ under the tree... still can't sleep because of the price/value ratio. But I hope my secondary camera will be a better bargain. :P

January 3, 2014 | Unregistered CommenterBalint

@Gerben The sj3000 design will be changed and the new version will support WIFI feature.
@Bulent The SJ4000 ompatible with gopro accessory.

January 3, 2014 | Unregistered CommenterBill

@Bill That makes the SJ3000 even more interesting! Is there an article with the new design and specifications? When will the new version be released?

January 3, 2014 | Unregistered CommenterGerben

Im very happy with my career, thank you!

January 5, 2014 | Unregistered CommenterDavide

it look like th SJ 4000 is on the marked,
Hawe enyone tested this ?
By the look it is more like the GoPro....

January 6, 2014 | Unregistered CommenterHaFa_NOR

Hi Techmoan,

When will you do the SJ4000 review? So looking forward to it because I can't decide between SJ1000 and SJ4000! So major questions are how long is the battery life is recorded in 720p? Can we change the default 720p @ 60fps to 30fps? Hope to hear from you soon!

Here is another Test with the SJ2000

This is another interesting video I found on youtube:

after watching this video I also disassembled the camera and found inside the same Novatek 96650 as the innov C1 or the Mobius camera.

January 27, 2014 | Unregistered CommenterDavide

Hi Techmoan, i found in a chinese forum a new firmware for the sj2000 camera. Can you test it for see if there are any differences from the old one?

February 27, 2014 | Unregistered CommenterDavide

I've got to say - having bought this camera, my experience is very different. I can't replicate the same issues you were having. Very pleased with the quality of the footage - colours, contrast and exposure all spot on. Build quality is excellent. I also have an sj1000, which has video quality that is genuinely indistinguishable aside from FOV. I find the SJ1000 terribly plasticky and cheap - the 'up' button has already lost its spring and is difficult to operate and the case is just plain nasty! I do still use it however when I need a viewfinder.

Another mate waiting to decide between sj3000 or sj4000..... which one has better video quality???

May 28, 2014 | Unregistered Commenterjose manuel

Hello, you can tell me how hide data stamp on video or you can give example settings fille?

June 17, 2014 | Unregistered CommenterSwinger

Tip our yourself, create file in root directory: time.txt with line 2014.06.18 16:26:00 N

June 23, 2014 | Unregistered CommenterSwinger

Hey guys, who knows how to turn the time stamp off the video footage. It says to create a Time File in the root directory. What type of file is a Time File, I've tried a standard text file and it doesn't work...

June 25, 2014 | Unregistered CommenterWill Park

Hey there. Can you recommend this camera? I like look better than the newer. How long can the accumulator. For me would be important motion tracking.

June 29, 2014 | Unregistered Commenterguest 01

Hi everybody. I received today the camera Eser-YD2000 (should be the same as the SJ2000, i bougth it on, tested it for a couple of seconds of rec and saw that the date was wrong so I tried changing date and time following the instructions manual but after power off and power on the camera does no longer enter in recording mode. Pressing the button for power on the blue light stays steady on and no vibrations at all happens. Pressin again once the button nothing happens, keeping the button pressed the camera powers off.
I tried more than a TF card, using Kingston class 10 cards.
The camera isn't also recognized by the pc via the usb cable.
How can I get rid of this and have the camera working?

October 9, 2014 | Unregistered CommenterClaudio

Update: I left the camera alone for a couple of days and when I try to power on it everything seems to work fine, the date also is up-to-date and the pc can see the camera.
Don't know what to say, as soon as possible I will try it on my motorbyke...
