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.

<Ok , but sir there is a remote for sjcam sj4000? And were I can buy it? Thanks for answering sir>

After much searching the best I could find was this...

Hope you can speak Thai. ;-)

Does not seem available anywhere. Well an official/original remote but do keep on Googling!

Found in my searching some interesting sites...

Still prefer Techmoan's reviews though. ;-)

Hi just been bought one of these WFI Sjcam 4000 how do you transfer these files onto an iPad air 2 ,it will not see them

January 31, 2016 | Unregistered CommenterBlack wolf

>Plus you didn't say it wasn't a helmet cam as one would assume

One might assume that if they ignored the fact that I used the words "dashcam" and "mount it permanently".

>Not necessarily so

Yes, necessarily so. You'll never achieve a faster transfer rate than reading it directly from the card, and going through the camera's USB port will always add additional processing. I defy you to show me *any* camera that transfers data as fast as a (Micro)SD card reader would. In fact, I'll be generous. I doubt you can show me one that even comes within 10% of the transfer rate of directly reading the card.

>Are you going to silicon up the hole every time you put it back in?

What part of "permanent" are you not understanding?

I'm looking for exactly two things here:

1) The data transfer rate over WiFi.

2) The data transfer rate over USB.

If you can provide me that data, great. If, on the other hand, all you can do is offer more misreadings and ill-informed opinions, then please just keep them to yourself.

In Reply to Jeff,

Good luck and sorry in trying to assist you.

LOL Hope your PERMANENT setup is not stolen but some people just don't listen do they?

What a pain disconnecting the unit every time you stop for a pee break.

Get a decent helmet cam!

January 31, 2016 | Unregistered CommenterPete Down Under

Hi all, I have a quick and possibly easy question regarding the SJ4000. I'm using the SJ4000 to record band practices and live shows, so the camera tends to shoot for up to an hour sometimes. I've turned both the car mode and cyclical recording off to prevent the deleting of old files when the card fills up. However, I now seem to have lost the one second overlap between clips. And instead, I now have a second or two of video MISSING when I join two continuous clips.

I actually need that one second overlap back, but I don't want to risk deleting files if the card fills up. Will the video overlapping return if I turn the cyclic recording mode back on? And is that the only way to get it back? Thanks in advance!

>sorry in trying to assist you

You didn't assist in any way.

> Hope your PERMANENT setup is not stolen but some people just don't listen do they?

The camera will be secured inside a steel case. I doubt anyone would go to the trouble. And what's with the snotty attitude? Some people don't listen to *what*? How does that phrase even make sense there?

>What a pain disconnecting the unit every time you stop for a pee break.

Go look up the word "permanent" in the dictionary.

Do you realize that everything you've said has been based entirely on your own INCORRECT assumptions? In the future, try sticking to what's been written instead of making dumb assumptions.

February 2, 2016 | Unregistered CommenterJeff

< "The camera will be secured inside a steel case" >

A steel case FFS! Sounds about as stupid as any of the other ideas you have put here so far.

I would love others to try and give you some suggestions but I gather they have noted your shitty attitude and stayed away.

< "Do you realize that everything you've said has been based entirely on your own INCORRECT assumptions? In the future, try sticking to what's been written instead of making dumb assumptions" >

I realise some dumb/rude F Wits do not deserve a decent answer seeing they pretend to know it all but still don't listen when others attempt to assist.

F off Jeff!

>A steel case FFS! Sounds about as stupid as any of the other ideas you have put here so far.

And what other idea has been stupid?

>I would love others to try and give you some suggestions

I've asked for two specific things, not "suggestions". You might want to get over your ego and learn to read.

>I realise some dumb/rude F Wits do not deserve a decent answer

You have yet to give anything other than uninformed opinions based upon your own misreadings.

> seeing they pretend to know it all but still don't listen when others attempt to assist.

I know it all? By explaining how your *assumptions* have been incorrect, I "know it all"? And I don't listen? Tell me again, where was it that you stated the WiFi transfer speed and the USB transfer speed, which is what I asked for?

Motion detection seems to be fixed at an 8sec video length which just isn't long enough really. Is this configurable anywhere or is that it?

February 3, 2016 | Unregistered CommenterDave

Thank you for the thorough, concise and unbiased review.

Your YouTube Video covered all aspects and as a result I have bought an SJCAM 4000 wifi. I am now using the video as 'the missing manual' going the the relevant section whenever I need it.

Congratulations on putting the video into English for non-technical people, minimising the 'tech-speak' and using the video to illustrate on the camera what you are saying on the soundtrack.

You were correct in saying that not everyone has a computer and linking to phones and tablets can be really helpful. I use an iPad Air 2 for many purposes and what was important to me was the wifi link. This allows me to review video on an iPad screen - which is much easier to read than the camera - and I can then delete or download via SJCAM Album to Camera Roll. Camera roll and iMovie allows straightforward editing and the results can be emailed or sent to YouTube/Vimeo whenever a wifi hotspot is available.

I sail and an advantage for me is that I can easily recharge both the iPad and Camera on the boat, or a car, without mains power.

I am grateful for your excellent review. I found it easy to install the most up-to date SJCAM App from the QR code on the box and it worked perfectly first time; your review has helped me in understanding the settings and what the camera will not do - as well as what it does.

Thanks again.

I just received this item/s from eBay and can honestly suggest all SJ1000 owners get one. The lens and button protector for the waterproof housing fits easily and protects the lens and also accidental turning on of the camera.

In two days I am off travelling Vietnam and will get great usage of this cover. Unfortunately the single lens cover for the camera when it is outside of the housing is too snug and won't stay/go on due to air pressure stopping it. Tried a small hole but no difference.

Anyway it was very cheap and the housing cap alone was worth it.

Thanks Paul for the post on the Firmware update.

Unfortunately I am waiting for my lift to the airport in 30 minutes so won't have the time to change anything.

If I have a good internet coverage in my hotel in Hoi An and don't hear any negatives about it I will update. Probably more so what positive changes it offers. Or I stick to the old, "If it ain't broke don't fix it" theory. ;-)

Once again thanks for bringing it to our attention.

February 27, 2016 | Unregistered CommenterPete Down Under

Dear Pete Down Under

Thank you for the response.

I would not suggest that the original review needs to be changed, it remains really useful to people like me who have no technical knowledge. The changes made by SJCAM don't change the value of your YouTube video and I think that it remains entirely valid as it stands. I used it to help in deciding to buy and then becoming familiar with the camera.

My purpose in sending the update was only to let users know that the menu now looks different - but it is not significant - the fundamentals covered in your video are unchanged. I agree with your "If it ain't broke don't fix it" approach and like your style of presentation.

I have to say that I am very pleased with the camera and the ease of use - thanks to your review. The 'Manual' with the camera is about as much use as a chocolate teapot!

Enjoy Hoi An.

Yours sincerely

Security systems are very important for the safety of the people as well as of the belongings. We are in the field of hardware and networking thanks for the information.

May 2, 2016 | Unregistered CommenterSanjay Das

Well, on the strength of both your review and the brilliant YouTube video I bought one and am seriously impressed. Super piece of kit for just a few pounds. I use it for cycling and it is solidly fixed to my cycle helmet via one of the multitude of different fixings that came with the camera. Just one thing is an annoyance and that is when I change the battery I have also to reset the time/date that normal or is it just me I wonder.

May 17, 2016 | Unregistered Commenterchris b

You could try plugging it into USB power when you swap batteries, but then again I suppose you only swap them when you are outside the house.

May 17, 2016 | Registered CommenterTechmoan

That is right. Not really a big problem, more a minor inconvenience and clearly one I will have to put up with

May 23, 2016 | Unregistered Commenterchris b

hey techmoan,
I have an sj4000. i just update firmware but the back screen is black.
I cannot seem to get it to enable the screen.

by the looks of it the camera is working but, without screen I am pretty stumped.


May 31, 2016 | Unregistered Commenterglenby

It's a long time since I used a SJ4000. I always recommend never upgrading firmware on those cameras unless you need to resolve a very specific problem and you know categorically the firmware fixes that specific problem. The problem is that there are too many SJ4000 variants out there so it's just Russian roulette.
If you can find an earlier firmware try to roll it back. Try the RC Groups forums. They might have something.

May 31, 2016 | Registered CommenterTechmoan

I just received an SJ 4000. Referring to your review at 2:55, the unit I received didn't have the vent holes shown in your video. Should I be concerned?

June 17, 2016 | Unregistered CommenterRey del Rosarii

Hi Rey,
Neither has my WiFi SJ4000 and is a genuine model. It has made no difference at all whilst travelling SE Asia with its heat and humidity locked in the waterproof housing 98% of the time.
Maybe Techmoan's WiFi model was an earlier edition of the WiFi model. Purely a guess but given the time frame a more likely scenario.

June 18, 2016 | Unregistered CommenterPete Down Under

Plz plz plz explain what does the new Underwater Mode do?
I mean actually do!
