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.

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.

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:

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 :-)

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 :)
