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%!

The Crocolis HD Extreme Cam - Longest review ever.

This is very likely going to be the only video review I'll make for a £100+ Action Camera and that's because when you get a camera that does pretty-much everything you want, then there is no need to go looking for another. The alternatives from GoPro, Contour and Drift cost considerably more and don't offer me anything extra that I need. I was really just looking for excellent quality 1080p 30fps and smooth 720p 60fps video with a nice sharp fish-eye lens in a waterproof case and an LCD screen - and that's exactly what I got.

The only significant issue with this camera is the sound quality. Normally this wouldn't be a concern because virtually all Action Cam footage gets overdubbed in post production anyway. But the problem with this camera is that the quality of it's video is so good that I am tempted to carry it around with me like a normal camcorder - unfortunately the wasp-in-a-tin-can sound quality means that it's not really a suitable as a camcorder substitute.

I think this might be the best (and longest) video review I've done so far. It's took a lot of time and effort and I think I've managed to cover everything that I wanted to. The only bits of info that may have got lost in the mix somewhere are the video formats - it's AVC .MOV - which imports into iMovie extremely quickly. One hour of video at 720p 60fps used up 3.63 GB of storage, the bitrates are CBR rather than VBR, the battery lasts about 2.5 hours and you can of course charge and record at the same time (very useful for time-lapse photography).

I'll just try and pre-empt some of the more predictable (but silly) questions before they get asked.

Does it work as a Webcam or have motion/sound activation? - No. Why? - Because it's not a Spy Cam it's an Action Cam. It's the same reason why your washing machine doesn't make toast.

If anyone desperately wants to see some original .mov footage from the camera then I'd appreciate it if you could suggest a reliable & free online place where I can post them. One that doesn't delete files automatically after a while. I would upload some 1080p and 720p60 clips, because youtube doesn't do justice to the brilliant video quality - the youtube clips look considerably softer and less vibrant than the originals. I didn't put the review on youtube in 1080p because you need a powerful computer to play 1080p flash video smoothly. *** Update - Clips added, see below***

I have to thank the 'extreme' skateboarding lads in Manchester - I'd imagine that they were more than a little bit concerned about the creepy middle-aged bloke asking if he could film them. Hopefully their Tony Hawks-esque videographer remembered my youtube channel name - please leave a message chaps if you do see this.

I'll be having a bit of a break for a few weeks before any more updates - but I can confidently say that the next video, whatever it is, will be a lot shorter and simpler than this epic.

This camera can be purchased from the nice people at Chinavasion - Here is the link


If you wanted to download some (unedited) sample clips to see the original quality of the video (before youtube has mangled it) you are in luck. Below are five clips, two are in 1080p30 and three are in 720p60. These are not the best framed/shot clips - but they are short enough to share.

If you are playing back these clips, you should download them first (right click) and then play them on your computer in Full Screen mode. I know that on my Macbook if I show the 720p60 stuff in a window then it only displays it at 720p30.

UPDATE 26 September - Important extra info about sound quality.

I've discovered that the mic hole on the front bottom of the camera seems to do nothing at all. However opening the rear LCD screen door does effect things immensely. With the door shut tight, only the loudest sound gets through to the mic (like shouting into a pillow), however with the door open, sound gets recorded at an acceptable volume. It's still rather hissy and metallic sounding, but a infinitely preferable to the water-in-the-ears type sound you get with the door closed. To record sound the door doesn't need to be wide open - just left slightly ajar.

As a further experiment I also removed the dummy screw in the base of the camera but this had absolutely no positive effect on the muffled door-closed sound .

On the subject of sound I bought a small microphone with a 3.5mm plug and found out that the socket on the camera is actually 2.5mm (apologies for the factual error in the video). Luckily I have a 2.5mm to 3.5mm adaptor and have tested out the microphone and noticed no obvious difference between the hidden internal mic and my new mic. So some good news and some bad news - the sound is better than I thought, but seemingly cannot be improved upon (I suspect a low bitrate sound encoder). The sound test in the video when I'm talking into the camera is still an accurate demonstration as the door was open throughout. I may do a follow up video when my second test mic turns up in the post. 

Further Update 26 October

I've been informed (see the comments) that the Sound from an external mic is actually OK, it just needs to be seperated out from the sound from the internal mic which also gets recorded at the same time, messing it up. I haven't tried this out. 

Also that mystery screw in the base is a kind of heatsink (in screw form) - so leave it screwed in.

Well I've just completed a 3 min epic, all shot pretty much under water in our local pool using the Extreme cam. I'm a swimmer in a team and the only real way to study stroke and style is from below - what your feet and hands are doing in air has little relevance in any stroke. Hope to find time to put it on Youtube one day.

I filmed with the GoPro in the same pool so I have a direct comparison and the differences are pretty marked, but then the GoPro's 3x the price. The Extreme cam footage was generally under-exposed and noticeably less sharp in air - but then it beats the GoPro under water. I used 720/60p for the widest field of view and I reckon the cam was shooting at max gain up (400ISO), max aperture (naturally) and its slowest shutter speed. I used auto white balance but the camera never really managed to get to grips with the pool's sodium (?) lighting and the colour balance below water is all over the place. In post I've managed to up the sharpness, exposure, and fiddle with the colour.

Overall I'm delighted with the camera. At the £106 price it's quite amazing.

can I use a NTFS card?

January 14, 2012 | Unregistered CommenterCarlito

Great review, but can you tell me, temperature under which camera works? i going snowboarding, So I'm looking for the camera which will work at low temp!

January 18, 2012 | Unregistered Commenterbollo

Well, here's proof that this little cam is waterproof.

January 19, 2012 | Unregistered Commentertom hardwick

Just done some low-light tests on the Extreme cam. The WVGAP 60 and 30 modes are awful. Next best is the 720/60p, then 720/50p. Best settings are 1440x1080/25p and 1280x720/25p. Use the latter setting if you want the greatest wide-angle coverage but with slightly lower resolution.

'Full HD' (1929x1080/30p) is a good stop less sensitive than 1440x1080/25p. Can't think why.

Best setting overall appears to be 1440x1080/25p at 7.83mbps A bit jerky in the pans of course but the 'more normal' 142 degree coverage makes the barrel distortion less of an issue.

did most of you bought from CHINAVASION? is it safe?

January 22, 2012 | Unregistered Commenterdigitalairman

Apologies, I appear to have deleted someone's comment. There were multiple duplicates of the same comment and I appear to have deleted the lot rather than just the duplicates. I don't want to look like I am censoring please repost if you can be bothered. The comment was regarding a camera failure due to water ingress and difficulties with getting a refund organised.

January 28, 2012 | Registered CommenterTechmoan

Hi, i've just received this camcorder, and i'm really disapointed of the qualiy of video, it's really noisy and there's a lot of blocks, maybe it's an firmware problem, can you tell me what is your version , and give me a link to download it?


January 28, 2012 | Unregistered CommenterTVSOUND

01.01.06 is my firmware version. Yes, fast motion footage will be a bit blocky at 7mbps but generally fast motion in itself will disguise this failing.

Great review! I'm thinking of buying this camera to put on the back of my Ferrari, to film some great shots from outside the car while driving and me sitting inside the car. But I also want to put it at the back of my Ferrari to record the sound while accelerating. Do you reccomend it? Oh, I also want to use it while skiing. Is there a good mount to put it on my helmet or my ski pole or even on the ski itself? Wich of the mounts do you reccomend to use?

I also put this comment on your youtube-video. I need an answer quick please.

Kind regards,

Willem (I'm Dutch BTW)

January 29, 2012 | Unregistered CommenterTheWillempiej

I don't recommend this camera for recording the sound of your Ferrari's exhaust. I'd suggest the GoPro range. They have better sound quality and should be within your price range.

January 29, 2012 | Registered CommenterTechmoan

@techmoan Thank you very much. But in Holland, this cam costs 130 Euros, and the GoPro costs 300 Euros, so I think I am going to buy this one, since I'm also going to use it for skiing.
Another question:
How about the zooming while recording, is it smooth or is it bad? Does is falter?

Kind regards.


January 29, 2012 | Unregistered CommenterTheWillempiej

What Techmoan means when he says the GoPro's within your price range is that you have a Ferrari, not a Skoda.
And 'zooming while recording'? The camera has a fixed focal length prime lens, so there'll be no zooming.

January 29, 2012 | Unregistered Commentertom hardwick

The same camera is all over ebay i have just bought this one

£111 but i did see one at £103 but when i checked the specs it didnt seem to have all the modes listed and the writing on the camera case was slightly different so maybe the Chinese are now cloneing their own stuff, anyway the £8 difference is 10 days in the post, as to, up to 30 days with the cheaper one.
Thank you so much for the time and effort you put into the review, the makers should be paying you a bonus because you certainly sold it to me, i wanted to avoid GoPro as although they are good i think they are also well overpriced.


February 1, 2012 | Unregistered Commenterwhiteturbo

Una pregunta. Es posible grabar sin ojo de pez?

February 5, 2012 | Unregistered CommenterAnonimous

Sorry, I speack Spanish, lol... so my quest is. Is possible record without fish-eye.

February 5, 2012 | Unregistered CommenterAnonimous

No, the camera has a fixed focus, prime, fish-eye lens. If you take stills you can remove a lot of the barrel distortion in Photoshop.

February 5, 2012 | Unregistered Commentertom hardwick

So, is not possible record video without fish-eye? Hummm...

- Sorry but I insist. I don't know, but we can see in your video record in the car (you write/say are 1080p. Elapsed time position 14:00) and not had fish-eye, so, how is possible?
I speak about HD video, no about Pictures.

Can you review this other? -

February 6, 2012 | Unregistered CommenterAnonimous

The Extreme cam only has a semi-fisheye lens. It's not even a full frame fisheye, which would mean it saw 180 degrees corner to corner. It's barrel distortion that people associate with fisheyes, but this distortion doesn't affect any straight lines that pass through the centre of the frame. I've got 1080 footage shot in the park and it's impossible to see any distortion at all, as the surface of the lake cuts right through the centre of the frame.


February 7, 2012 | Unregistered Commentertom hardwick

First of all Congrats for the detailed review. After using a friend's cam and watching your review, I ordered it 10 days ago. It came in yesterday.
There 2 things that I can't resolve.
1. When connected with my Sony TV, via HDMI, there is no sound played from the speakers at all.
2. When I connect it with my computer, I do have sound using the Quicktime player, but I don't when I use the windows Media Player.
I also have anothe issue, but I think I 've got a solution on this. The mov files do not bring any audio at the Pinnacle 15 HD. I found out that if I use the Xilisoft video converter and convert it to mpeg4, then the audio seams to be ok at the Pinnacle.

So as far as the 2 first I will be expecting your opinion and advice.

Thanks in advance,

February 15, 2012 | Unregistered CommenterBatFalcon

I use Pinnacle 15 HD too! I ordered this cam as well, but it hasn't arrived yet! I've read comments of more people using Pinnacle with the same issue. I think I better download Xilisoft now!

February 18, 2012 | Unregistered CommenterTheWillempiej


Xilisoft does a fine job, but it reduces the frames per second. If you have shoot the video in 60 fps you will get a result WITH sound but in 30 fps.
From what I hear there is also an other (light video editing), program of Corel, which inserts the clip without any conversion.

February 18, 2012 | Unregistered CommenterBatFalcon


Thanks for the information. Another question: Does it automatically converts it intio MPEG4 when you press the convert button?

February 19, 2012 | Unregistered CommenterTheWillempiej


First you select the .mov file you want to be converted.
Then you decide what type of extract file you want.
Then you select the folder where the new file will be generated
An finally you press the big red button. When it finishes the new file is ready, where you wanted it to be.

February 19, 2012 | Unregistered CommenterBatFalcon

Thanks mate, you've helped me a lot! What are you going to use the cam for? I'm going to use it for extreme video's with hypercars in it, to film massive accelerations from close by! I can't wait till the camera arrives! If you like cars, you should check my YouTube CarChannel
Do you have a youtube channel as well?

February 20, 2012 | Unregistered CommenterTheWillempiej

Yeap. My channel is Mostly with RIBS. I 'll check out yours.

February 20, 2012 | Unregistered CommenterBatFalcon

Terrific review. Thanks very much.
One of THE best reviews of ANYTHING I've seen on the web.
Thorough, unprepossessing and includes all the information I'd like to have.


February 26, 2012 | Unregistered CommenterPeter Lake

Can you record at 720p 60fps with the 137degrees FOV instead of the wide 170degree fisheye ????

March 2, 2012 | Unregistered CommenterFranky!

@Franky! The FOV is determined by the resolution that has been set. 720p is always wider than 1080p on this camera.

March 2, 2012 | Registered CommenterTechmoan

Just to say that my Extreme cam has started to play up, but only when used as a stills camera. It will grossly over-expose every so often, almost as if it's stuck on max ISO and the slowest shutter speed, regardless of the lighting conditions. When it's being used in really bright light it's ok, it's only when the light levels drop that it loses control. And having the picture is shown on the rear screen for only a fraction of a second after taking it doesn't help much.

Still, when it's working well it sure works well.
