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. :-)

July 16, 2012 | Unregistered CommenterAndy

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.

July 16, 2012 | Unregistered CommenterRubberman

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!

July 16, 2012 | Unregistered CommenterMark Mevius

SOLD...! :)

Thanks for the review...

July 17, 2012 | Unregistered CommenterViper

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.


July 17, 2012 | Unregistered CommenterMartin

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!

July 17, 2012 | Unregistered CommenterPete

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.

July 18, 2012 | Unregistered CommenterGeorge-Romania

mic solution?:
And using ultrasmall wires like these:

Probably no problem with closing the display. Other end fitted with a contraplug. Just some tape around the new connection, and i think it will be watertight enough for rain. And still have good sound quality!

Pity the camera is so expencive... Otherwise i would have tried it myself.

July 20, 2012 | Unregistered CommenterRutger

Great review Techmoan.
You did rather complain that the camera was making the shot too dark, but in reality he had lots of sky in the shot and the camera was simply adjusting the overall exposure to give the best result. No clever spot metering or centre weighting here.

You also said the camera took a long time to adjust its iris to the changing lighting conditions, but I'd be very surprised to learn it had something as expensive as an iris on board. I'm betting its the same as the Extreme cam in that exposure is controlled by adjusting the ISO value and the shutter speed per frame.

You're right to say the front element is a piece of flat plastic (so that the cam shoots sharp footage under water) but the new design stops you using the top off a WD40 can as a push-on lens cap. About the only thing missing from that box of bits 'n' pieces.

Another cracking review - how did you manage to find enough dry days to get the footage ;-)

July 20, 2012 | Unregistered Commentergrahamk998

Grahamk998 Are you for real? I heared something to the effect that UK only got 1 Sunday a year but is this for real? Its such a struggle to find at least no rainy days?

July 20, 2012 | Unregistered CommenterGeorge-Romania

How's the sound quality? is it so much better? And the mountings did it jump off?

July 21, 2012 | Unregistered CommenterPinoy Pilot

Pinoy,off course it didn't jump off :| And yeah,sound its not so much better,its perfect.Check out the video and you'll find out.Its an awsome video and a briliant review.

July 21, 2012 | Unregistered CommenterGeorge-Romania

I've got one of these, here is a video I took from my bicycle.

and a comparison video taken with another (1080p) camera, on the same circuit, same time of day just another day.

I didn't use the included bicycle mount because it was kinda heavy and made the camera stick out too far for my liking, I used a custom modified mount I made myself.

July 22, 2012 | Unregistered CommenterOz

I'm thinking about buying one, but I'm not sure. How deep can it be under the water (recording, of course)? Can you hide all the info ( date, hour, ...)?

I hope someone help me.

Jose SJD Its in IP 68, about what can find more about here " " .For what 6 and 8 from IP 68 mean check the table.You'll find 8 mean its waterproof over 1 m however it can meen something else too.At other producs i saw IP 68 up to 3 m though it depands on the materials used,what water preasure they can stand at but i think 3 m its preety safe,though it wont be suiteable for open water sea or ocean diving cuz you usually dive more than that.Limit its probably the coral reaf is at few meters.If you dare you can go up to 5m and after like 30 m if nothing happens let us know :P Or wich the limit is ,more or less then like 3 m :P

July 24, 2012 | Unregistered CommenterGeorge-Romania

I wanna mean 30 minutes not meters :)

July 24, 2012 | Unregistered CommenterGeorge-Romania

Tom, About the iris thing - I'm no expert in cameras - I'm just an end user, so I'm probably using the wrong phrase, by using human words to describe electronics. I thought there was such a thing as an electronic iris that controlled the light, if not then I'll have to adjust the way I describe how rapidly cameras can react to light in future videos.

The reason I thought the footage was dark, was because when I put the Crocolis camera in the same mount the footage wasn't as dark - so something is amiss. If I hadn't mentioned it then some clown would then accuse me of being too uncritical and being in Chinavasion's pocket- it's impossible to win, or even lose gracefully in these situations. Maybe I should avoid cameras for a bit.

Hi. Back again.
As a further comment from my top one, I have received the camera now and used it a bit and can only say that I'm pleased with the video results. But, as far as sound goes its rubbish.
I am now going to get another 808 camera and modify it to accept an external microphone as I did with the last one I had (which I accidently buggered up by trying to fix the car charger and subsequently fried the battery somehow).

I tried different decent microphones but they all were too distorted. I also taped over the hole for the internal microphone but it was not good either. I usually use an external mic situated under the seat towards the rear of my bike and it worked fine on my modified (external mic jack socket & fish-eye lens) 808 keyfob cam.
The exdreme cam seems to be set far too sensitive for sound.

Dear TECHMOAN, if you're in touch with the manufacturers can you see if its possible to flash the sytem so as to make it less sensitive to sound.

Link above is an old vid from the 808 keyfob cam. I'll post one below somewhere for the exdreme cam when I've uploaded it.


July 25, 2012 | Unregistered CommenterAndy

Hi Techmoan, I know what you mean when you say you can't win or even lose gracefully; I write the technical articles for Film and Video Maker mag and I'm very aware that there's far more tekky people out there than I will ever be and I'm picked up on the tiniest things. But don't stop reviewing cameras the way you do - I find them excellent.

No, no such thing as an electronic iris or electronic ND filters. The exposure is controlled in the simplest possible way, by having an ISO and shutter speed combination that lets in the 'right' amount of light. Easily checked by using the cam for taking stills in all sorts of lighting conditions and viewing the meta-data on each frame.

All cameras are set up slightly differently as regards exposure, so I didn't see that underexposed road shot as anything you'd done wrong or differently.

Vid for xdreme cam:

July 26, 2012 | Unregistered CommenterAndy

I didn't plan to buy such thing until I find your excellent review. I watched every pieces about cams at one (long) night, so now I've got my own Xdreme camera, and I'm very happy with it.
I'm actually testing all of the functions, using like car cam, and I will use it on my RC glider. Also have a plan to make video with auto capture feature.
I will check your site time to time for new reviews.

Modified sound exdreme camera

July 30, 2012 | Unregistered CommenterAndy

Thanks for a brilliant review. Your videos are very informative and funny.
Keep up the good job. I really appreciate your videos.

I bought the Exdreme camera from Chinavasion and I'm positive so far...

BUT there is one thing the guys forgot in the menus:
The DELETE option. One cannot delete a movie or photo. It gas to be done from a PC/Mac.

I give the camera a very high rating and recommend buying it :-)

August 1, 2012 | Unregistered Commenterjenshenrik

I have been deleting videos from this camera. Press the menu button to get to the video file context, here you should see thumbnails of your videos, hit the record button to bring up the delete option. Same goes for the photos.

Thanks for the review.

I purchased this camera after seeing the review on the Crocilis camera, and going to Chinavasion's website, I noticed that this was the successor to that camera. I have to say I'm quite pleased with the camera so far, and I've shot a ton of footage on it. As an experiment, I shot footage in every different resolution, and dropped them into a Final Cut X editor, which handled all of it with no problems.

As far as the waterproofness of the camera, I used mine in a rather large aquarium at a local museum, and it is waterproof at 2 meters. One note though, it is positively buoyant, so unless you attach some type of weight to it, the camera will float. I ended up using a piece of PVC pipe attached to the right angle mount which came with the camera so I could steer it to where the fish were. It does well underwater, and the audio is actually quite acceptable, you can hear all kinds of fishy noises.

Due to the fixed lens, the camera does not focus really closely, but that's to be expected, the only time we noticed was when a fish got right up into the lens. Other than that, it's quite amazing video, especially for an inexpensive camera.

I've tried out the motion detection, and in full HD, it can detect a cat switching it's tail at 4 meters. I've not gone much further than that with it, but it does seem to work well. It also detected a piece of paper waving when the air conditioning came on.

Overall, I'm quite impressed with the camera, and despite the complaints about the audio with the back closed, I've been able to use the audio that I did get for synch audio for editing purposes, we almost always record audio on another dedicated audio machine, or another camera which is set up for external audio.

You're right. It is possible to delete files.
Thanks for correcting me :)
