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.

Just purchased a SJ4000 wifi from a local authorised seller here in Singapore after seeing your awesome review. Will definitely be keeping track of your website for tech updates. I've downloaded the app on my iPhone in advance and honestly it does look abit dodgy and outdated. Getting my camera tmr, fingers crossed that it will work. Cheers :)

I want to extend the wifi range of my sj4000 wifi camera by about 3m - how can I go about doing this?

At present, I intermittently loose the signal, and the image locks up on my android tablet. When the tablet is one metre from the camera - voila, ideal picture. Beyond that, it pixellates or locks

Look forward to hearing a solution, many thanks

I am seriously interested in getting the SJ4000 but have noticed that Rollei have released the Actioncam 400. Have you managed to check this camera out to see how it compares. It's is slightly more expensive than the SJ4000 (£20-£25), but looks to be of a better build quality and looks to have a better screen on the back? Although not sure about the quality of the video or still images? Can you help? Cheers

June 12, 2015 | Unregistered Commenterdavygee

Thanks for all of the reviews - I have struggled, read, watched and researched and finally came down to the SJ4000 WiFi. I did seriously consider the Mobius and also the Garmin Virb (which you have not reviewed). As Garmin are just about to release new versions of the Virb - I really toyed with the idea of a Virb as I have a Garmin Edge Touring Plus on my bicycle. But it was just too expensive for my first foray in to action cams. So I plan to film some cycle rides and also some of my band gigs. I might even try it as a dash cam sometime.

I bought mine via the link to eBay to ensure I got a pukka SJ4000 and not one of the fakes. It came in a couple of days.

So again a big thanks for the time and effort you have spent, you have certainly helped me.

June 12, 2015 | Unregistered Commentervsmith1

First of all thanks for the brilliant reviews. Just found this site and invaluable. Seriously considering the SJ4000 wifi. I note that there might be either a 140 or 170 angle camera but I am not sure on this. Are there these options? Do they apply to all the models of the camera?

June 19, 2015 | Unregistered CommenterEdgecam

If i need to run the SJ4000 with WIFI enabled for many hour to grab the stream through VLC... what kind of way you would supply energy??
Battery life is very short ( just 40min)
Connected to a USB 1A Power supply .. the Cam died after 1 hour (maybe it feeds the battery instead of the cam but i't not enough to keep the battery up)

So what do you suggest to avoid disconnection of the video stream??
Thanks a lot.

To Fabrizio
I had camera SJ4000 connected via powerbox ( circa 12000 mAh) for 8-9 hours. With no wifi turned on, but with with detect of motion on. It works very good, powerbox was drained out one half capacity.

To Edgecam:
You can buy replacement lens for SJ4000 (originally for gopro cameras) for circa 10-12$. The lens change is quite easy. I saw these lenses on Ebay (170 and 150 degrees wide).

Hello, good review, i decided to buy SJ4000 and here is my first video: made with it

July 23, 2015 | Unregistered CommenterGed

Hi there,
Hope you might be able to help, I've been trying to import my photos from my SJ4000 using a genuine Apple lightning cable but it isn't working connecting it to my mini iPad. When connected it just says no photos to import.
I took it to the Apple Store yesterday and they couldn't help. Here is what's happening.
I am using a Samsung 32 EVO micro SD card.
I can download photos using USB cable plugged into my laptop and into camera.
If I put card into Apple lightning cable it says no photos to import.
If I put card into my digital camera and take a photo it will import it to my iPad
If I put the SD card which is normally in my digital camera and put it in the SJ4000 and take a photo it will show it back on the camera but not import it to my iPad
Have you any ideas what is wrong, as I want to import photos to my iPad and not my lap top.

With Thanks,
Mr G Watson

This is a one year old article. Here is a link to my seven month old review of the SJCAM SJ5000+

September 9, 2015 | Registered CommenterTechmoan

Do you have to use the wifi setting like what if you are in a pool. Aslo what was the main difference in the sj5000 and sj4000. Also when did these cameras come out and is another one coming out soon.

September 14, 2015 | Unregistered CommenterTaylor

The WiFi feature can be switched on or off - the camera works either way. See 11:45 to 12:30 where I use the camera functions including turning the camera on, start and stop recording and changing modes - all without turning the WiFi on.
If you don't need WiFi I'd recommend the Dazzne P2 over the SJ4000 (with or without wifi)

September 14, 2015 | Registered CommenterTechmoan

Can anyone give me some advice please. I've got a sj4000 wifi camera.
I've set up the app, so I should be able to control the camera from my iPhone.
I can't seem to get the zoom function to work via my iPhone, when recording video. Even if I use the zoom on the camera, the wifi connection cuts off, and I can't see what's being recorded on my iPhone screen. Any ideas please

Can I stream video over wifi to a laptop?

November 12, 2015 | Unregistered CommenterSam

Been googling for a while and i cant watch the video on my device so can anyone answer the following question.

If you rotate the camera does the image rotate or does it stay with up always up?

November 15, 2015 | Unregistered CommenterSteve

There is a rotate 180º in the menus - it isn't automatic, there is no orientation sensor.

Hey Mat,

Any plans on reviewing the SJ5000X?

January 17, 2016 | Unregistered CommenterFreddy

I have a SJ5000 (non-wifi, non plus) and it is kaput. For some reason a diode popped on the front of the mainboard near the battery connector. I am trying to find out what type the diode D2 might be.
My picture is with the popped diode is on Youtube :
I really want my camera back working !!!

Thanks Techmoan,

Through your marvelous reviews I have gone from the Mobius (It developed a hiccup or I gave it one) to the SJ1000 and now the SJ4000 WiFi. The SJ4000 may match the Mobius as my handy travel cam and must admit after only a couple of days the 4000 may come close. ;-)

Bought mine through GearBest and it checks out as an original SJCAM and noted it says...
Version: V1.1.1
Date: OCT21 2015

...but have noted the ventilation holes on the bottom next to the battery cover are not on mine. (WiFi model) Any thoughts?

Oh!...and my stupid question of the day is how do I check which FW? The menu just gives me the above info under Version.

Answering a couple of older questions here...

Having read a couple of posts here about people updating their Firmware and the Contact buttons then not responding.
Well I hate to tell them they may have FAKE SJ4000 cams.

See here for the bad news...

Very nice website for cctv camera dealers in chennai.

One thing I haven't heard much about is the transfer speed over WiFi.

I'm interested in the SJ4000 or SJ5000 as a waterproof motorcycle dashcam. I plan to drill the waterproof case for USB power (with silicone sealant, of course) and mount it permanently.

Is it worth getting the WiFi version for easy transfer of videos? I suspect it's extremely slow and I'd be better off connecting directly over USB. I'm sure that a direct SD card connection to my desktop would be ideal, but like I said, this will be a permanent installation.

So how fast is the WiFi download? Should I just use USB?

January 25, 2016 | Unregistered CommenterJeff

Hi Jeff,
My thoughts...

>"I'm interested in the SJ4000 or SJ5000 as a waterproof motorcycle dashcam"<

As good as this camera is why would you use such a non streamlined, bulky camera as a permanent helmet cam? Read Techmoans reviews for better alternatives to suit your needs.

>"Is it worth getting the WiFi version for easy transfer of videos"<

Not in my opinion. Cannot tell you if mine is that fast as I haven't bothered with it after my Android phone was having so much trouble connecting. (Read failed to find it)

>"I suspect it's extremely slow and I'd be better off connecting directly over USB. I'm sure that a direct SD card connection to my desktop"<

I find it very easy and fast using a USB cable from the cam to my laptop.

>" I'm sure that a direct SD card connection to my desktop would be ideal, but like I said, this will be a permanent installation"<

Why bother taking the card out, putting it into an adapter then into your PC?

As I said above USB is easy and why this cam for a permanent helmet cam?

PS: I just thought if you are using the SJ4000 (Or most other cams) why are you considering such things as compromising its waterproof housing to run a cable???

Just use one of the accessories that come with the camera to mount the housing and when needed release the camera to transfer the videos as per normal. Finish and then put back in housing and reattach camera to your helmet.

Jeez! Glad that morning coffee finally kicked in. ;-)

January 25, 2016 | Unregistered CommenterPete Down Under

> as a permanent helmet cam?

I never said anything about a helmet cam.

>Why bother taking the card out, putting it into an adapter then into your PC?

Because it would almost certainly be much faster than transferring data from the camera over USB 2.0.

>why are you considering such things as compromising its waterproof housing to run a cable???

Because I intend to wire it for power. What, you think I'm going to stop every 80 minutes to swap the battery? This camera will be in use for many hours at a time, with zero manual intervention.

January 26, 2016 | Unregistered CommenterJeff

<I never said anything about a helmet cam.>

Told you the morning coffee hadn't kicked in. Plus you didn't say it wasn't a helmet cam as one would assume seeing you mentioned motorcycle and Techmoan mostly reviews bike cams as helmet cams.

<Because it would almost certainly be much faster than transferring data from the camera over USB 2.0.>

Not necessarily so and a damn sight fiddlier. IMO

<Because I intend to wire it for power.>

Good luck considering the tolerance between the housing and the camera. Are you going to silicon up the hole every time you put it back in?

Hopefully others here can be of assistance and offer their thoughts.
