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%!

Xdreme Camera Review

Does the Xdreme (Blue) improve upon the Crocolis (Red)?I'm trying to catch up on my reviews at the moment, so if in my rush I've forgotten to include something in this video, let me know and I'll try and cover it up in a future mop-up video when I've got sufficient time.

One thing that I did intend to mention was the size of video files created by this camera. People with good math skills can probably work it out from the video bitrates, but for the rest of us I can confirm that in my tests 15min at 1920x1080 30fps took up 970MB of space. 

One thing I know that I didn't test is motion activation. I know that some people are interested in this feature, but I really can't figure out how to demonstrate it in a meaningful way. Clearly, when the camera in this mode if I wave my hand in front of the lens it starts recording...but is that all people really want to know, because it all seems rather rudimentary to me. Let me know.

If you want to download a few short samples of clips from the camera Here is a folder on pcloud.

I am trying out affiliated links, so here is my link to the Xdreme camera on Chinavasion. Remember though that in the UK, you will likely get stung with customs and 'handling' fees when you import from China, so factor that into your budget.

Thanks for that. I was hoping you would get round to this one. After breaking my jumbo 808 I was in desperate need of a new one and ordered the xdreme camera.
Luckily your review shows I won't have wasted my money. Just waiting for its arrival. :-)

Thank you! Excellent review - not often is a single review enough to purchase an item, but this covered all my questions! I will be going with this one.

Excellent review as allways! Do you have a cat? Maybe that's a nice subject for the motion detection functionality. You could point the camera at a place the cat frequently visits for a day, see what he's up to while you're at work. :-)

I've got a question about the automatic image orientation: does it level the video like a leveler (ie is it level to the horizon), or does it just turn the image at 90 degrees steps?

Owh, and another question: Could you use it as a we.... ;-) just kidding...

July 16, 2012 | Unregistered CommenterGerrelt

@Gerrelt I don't have a cat, but it was a sound idea. The orientation sensor just flips the video the other way up (180°).

Thanks for the review! Ordered the Xdreme HD two weeks ago. Looks like a good purchase to me now!

SOLD...! :)

Thanks for the review...

Splendid review, as usual.

I managed to wreck my Crocolis by somersaulting a motorbike on top of it.
It still records but is cosmetically challenged and structurally compromised.

This looks like an excellent replacement for when I'm suitably recovered.

I could not find any specifications as to how deep you can take this camera into the water. I asked Chinavasion, too, and they said they don't know. Have you any idea how waterproof this camera is?

Thanks for the review!

Techmoan, thank you very much, great review as usual. I was expecting a higher bitrate on this one. The footage looks really good, I want to buy it but there is one thing. For the color correction work we need like 2 or 3 times as much bitrate than it gives now, or the footage breaks apart at color correction. Can you talk the guys at Crocolis into releasing a firmware that gives an "extreme" quality setting, which gives higher bitrate? Manually adjusting shutter speed and/or an exposure lock would be nice too:) Gopro claims to release a firmware update called "protune", which adds a new recording bitrate of 35Mbps. The guys at Crocolis need to catch up :)

As i sad on YouTube its an excelent review of a camera that solves a lot of issues and is the video that got me most excited i was in year,i was like a kid in a candy shop.Anywayu :) ... As another fellow blog viewer said,you could use a cat or any kind of big animal for motion detection so we can also HOW FAR or better said CLOSE action has to be to trigger it.Another thing is that you could get the camera facing forward clamping using the handlebar mount either on handlebar by holding in place that rubber or foam piece with zip ties either on bikes forks.Beside that i can't point another lack in the video.Again thanks for this and the rest great review.I'm pretty sure im not mistakeing when i say you had found the second call.If you ask me,you're one of the best reviewers if not video uploaders on youtube.
