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%!

At last it's the Real SJ4000 WiFi Review

Here at last, is my review of the SJ4000 WiFi review. Whilst there isn't a massive amount of difference between this and my original non-wifi version, somehow I've managed to stretch this out into a half hour video.

If you just want to know about the WiFi function and whether there are any other differences between this and the older models, you'll find your answer in the first few minutes, so no point skipping to the end. 

In this video I also take a minute to explain why you should think twice before ordering the SJ5000 camera that's doing the rounds at the moment.

My video review is below.

There are four reasons why I won't review any GoPro devices.
1) GoPro have been known to demand that reviews are taken down if they use their product image, names or logos. (See ) . Since it takes me a month to make each review, I don't want to spend this time on something that no one will ever see.
2) Everyone reviews GoPro cameras, so there will be plenty of other (professional) reviews to read.
3) I don't like the shape of the GoPro cameras (as I mentioned in this review) they just don't suit my needs at all.
4) Some GoPro 'Fanboys' can be crazy (probably on a par with the One-Direction fans). I don't want to receive death threats for criticising their beloved product in any way.

First, an excellent review! It's quite entertaining, and focuses in all the aspects that really interest. Maybe the only missing point would be some underwater imagery, as said by someone before.
Second, do you know if it's possibile to use the "Unnamed" Pro brand battery's in SJ4000? It's a pity that no high capacity batteries beeing available... at least to my knowledge.

Thanks, and keep up the good work!

September 30, 2014 | Unregistered CommenterEduardo Costa

Unfortunately I'm not your guy for water based footage - but there are lots of much cooler diver-dude type guys who are posting good SJ4000 footage on youtube.
I haven't got a GoPro battery to test, I can't imagine it fitting any more than my Sony Action cam battery will fit in a Contour camera, but I'm sure someone who does have both the Sj4000 and a GoPro will kindly provide a definitive answer.

Hello Techmoan,thanks for review, an amazing one like always,i want to buy a sjcam sj4000 with sj brand on it, but without wifi(i don't need wifi, i prefer to download the movies on my pc) and i want to ask you, because i saw in the past sj4000 review that the battery life on 1080 30 p with screen of after 1 min it's 100 min right? And this version with wifi it's 95. I'm wondering because i know the wifi reduces battery life ,if i will buy a version without wifi,the battery life will increase?

October 1, 2014 | Unregistered CommenterKoKo

A small difference like that will just be down to something like the temperature of the room rather than any difference in the device. The next time I did it, I might have got 105 mins. The Wi-Fi was off for this test. I haven't trIed a battery test with Wi-Fi on, but expect it to have a drastic effect on the battery life, probably reducing it by more than half.

October 1, 2014 | Registered CommenterTechmoan

Which camera should i take sj4000 or wifi version? I don't need wifi, i only care about the video quality. Does the old one have newest firmware and is video same quality and look as the wifi version?

October 1, 2014 | Unregistered Commentersj400orno

Great review!!
One question though, is the only difference between the 2 models is the wifi feature?
I saw in some sites that the sj4000 wifi model has F.O.V(D) of 153.67.74, I'm not sure what it means, but i thought it's supposed to be 170 degrees.

October 1, 2014 | Unregistered Commenteridan

Hello Techmoan! I like your video on the SJ4000 wifi. I would just like to know if you can use the SJ4000 wifi as an IP camera for live feeds or streaming? Does it have an IP address?

Thank you for all the effort!


October 2, 2014 | Unregistered CommenterJohn

Hi techm(l)oan,

Just curioso, ho much the WiFi affect battery duration?

Is it possibile to switch WiFi off from the phone/tablet?

Thanks! Great review as always!

October 4, 2014 | Unregistered CommenterNicola

Just bought after seeing your review. Ordered mine via Amazon Coshinegroup for £64.90 including 2 batteries. I assume genuine since through Amazon. Should be with me within 4 days

October 4, 2014 | Unregistered Commentermcmac


My camera does not connect to my phone. I use samsung note2. I can see it in the networks but when i try to connect but it says connection is poor. Help please! Thanks!

October 4, 2014 | Unregistered CommenterPhilip

Where can I buy one in Los Angeles CA?

October 5, 2014 | Unregistered CommenterArnie

I would very much appreciate a comparison between the SJ4000 wifi vs the new low end GoPro 4. Since the price difference are very minimal now.

October 6, 2014 | Unregistered Commenterrcboosted

I tried buying the SJ4000 a while back but it never got sent as the vendor was removed (got refund from ebay). I have since bought a a GoPro Silver 3+ and I still want this SJ4000 to compare and will give one to my dad, and take any mounts he doesn't need!

Anyway, thanks for the review (haven't watched entire video yet). And please provide a referral link if you have one. The foxoffer link isn't working for me.

October 7, 2014 | Unregistered CommenterBen

Any idea over what distance the wifi can be used?

Great review by the way.

October 7, 2014 | Unregistered Commentergeoff

What program did you use to download the videos to your computer? Would this product work with GoPro's download program from their website? I have a feeling it will not, but thought I would ask anyway. Thanks,

October 7, 2014 | Unregistered Commenternewolf17

Now that I have the SJCAM4000 WiFi, I'm curious as to what editing software did you use to make your clips. I tried the Gopro Studio and it did not recognize the .mov. I tried Vegas Video and there is no video (Audio only). Am I missing a codec or something? I can play it ok with VLC or Quicktime. Please help. Thanks...

October 7, 2014 | Unregistered CommenterKiwiMan

I use iMovie (Mac) however you will probably have more luck with your setup if you install the K-Lite codec pack.

October 7, 2014 | Registered CommenterTechmoan

In your review you mention a few times that the sensor and stills are only 2 MP and that setting it higher is useless.

Are you 100% sure of this? The camera claims to have a 12 MP CMOS sensor and many of the competing cameras take the full 11 or 12MP stills.

It's quite common for HD video cams to have sensors much bigger than the actual HD output.

Can you confirm where you obtained this information?

October 8, 2014 | Unregistered CommenterCraig

I've used deductive logic, I haven't disassembled the chips.

If you prefer I could say that the '12 MP' mode takes stills that are identical in quality but much larger in file size than the 2MP stills.

Over the years I've seen scores of cameras that overstate specs, this is just one of them.

October 8, 2014 | Registered CommenterTechmoan

Just got mine today, as soon as i put the battery in, the camera constantly turns itself on (automatically recording) and off again, anyone else had this problem. it not only wastes the battery but the memory also!

October 8, 2014 | Unregistered CommenterMelissa

i just bought one , sj4000 wifi , singapore dollars 185 at a local singapore store .
i still dont know how to update the version sj4000 wifi thru my laptop .

October 9, 2014 | Unregistered Commentermohamed

Which would you recommend for better still photos: the SJ4000 wifi or the Sony HDR-AS15?

October 10, 2014 | Unregistered CommenterChris

The Sony Cameras take much better stills. Download some samples from both cameras to try them out for yourself.

October 10, 2014 | Registered CommenterTechmoan

I Bought the SJCAM SJ4000 wifi from amazon. It connected wifi to my android phone fine multiple times. Then i connected to an iphone, and now it will no longer connect to any android phone. Im sending it back

October 14, 2014 | Unregistered CommenterAngelo

Hi, any news on a version with a larger screen anytime soon?

October 14, 2014 | Unregistered CommenterDamian

Dear Techmoan,
Thanks for the review.
I'm curious which model do you prefer : AT200 WiFi or SJ4000 wifi?
Thanks for your answer.

October 15, 2014 | Unregistered CommenterTibke

Thanks for this great post!

I hope somebody can help me with a problem.

I'd like to use the camera mostly for running, and I haven't seen any topic, video or post about that whatsoever.
So my problem is that the recorded video is shaking terribly I don't think thats normal.

I made a video about this :

I know the quality is bad, but you can see my point. ( from the 1 minute mark )

I have the head mount, and I tryed to record in different resolutions, but all are the same.

What can I do about this ? Any suggestion ? Thanks a lot.

October 15, 2014 | Unregistered CommenterNatham

Hi friend: Could you tell me if you know the ishare s600w or s601w cameras, and what do you think about these? Here is a link . Do you have a review about it? Thanks.
