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!

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?

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.

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?

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.

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!

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!
