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%!

Mini Key Ring Spy Camera Review

I've found it impossible to mount my DV80 camera to my motorcycle helmet - so I bought  a keyring spy camera (or two) to replace it - but I've found that the improved ease of mounting comes with a number of  trade offs.

The camera cost me £10 delivered to the UK from a Ebay HK seller.

This looks really good! have you got a link to the seller you bought from? i want one! =p

April 7, 2010 | Unregistered CommenterDale

No problem. The Ebay seller is called POWER-GPS.

Hi TM, Uhm, I'm not sure how you can test this, but how waterproof is the DVK808? :-)

April 7, 2010 | Unregistered CommenterAmbrose

Second question. :) What happens when you go over 11 minutes with a 1GB TF card? I want to use it as a way to record the last few minutes of my ride (as sort of a last will and testament) of any possible accidents that may occur. Hopefully, it just keeps recording, so that only the last 11 minutes are captured.

April 7, 2010 | Unregistered CommenterAmbrose

Waterproof - not at all - if any water gets in any of the various holes it will certainly kill it. The SD card slot is especially vulnerable.
I understand what you mean about the last 11 mins - you really want an accident cam. But unfortunately when the SD card is full it just stops recording. A real accident cam will keep re-recording until it hears a loud smash then it stops. Without that ability it would just end up recording over the crash footage with video of the bike being towed away or the scrapyard etc until the battery died.

Thanks TM for your great reviews!

April 8, 2010 | Unregistered CommenterAmbrose

No problem - it gives me an excuse to buy more stuff I don't need.

April 8, 2010 | Unregistered CommenterTechmoan

Hey TM,

I just bought a couple of these min-cams so will report back when I've played with them a while. Thanks for tipping me off to these tiny cameras.

(PS., would you mind emailing me at my gmail address so that I can contact you directly?)

April 26, 2010 | Unregistered CommenterAmbrose

Hi TM,

I've had these cameras for a while, but haven't really done much with them. I plan on using them on my helmet as a simple bike ride recording device. They are great as you state. The quality is great for the price. The form factor is right. The only thing that isn't perfect about them is that their field of view is somewhat narrow as you correctly stated.

Do you know of any hack or DIY add-on lens you can stick on the front of these key chain cams to give them a wider field of view without compromising the quality of the video too much?


May 19, 2010 | Unregistered CommenterAmbrose

Hi Ambrose.
Great minds think alike - I've got a mini stick-on wide angle lens winging it's way to me in the post (mail) as I type. I really bought it to stick on a webcam that I use as a wifi security camera, but I'll also try it on the key ring camera to see if it works out (it may be tricky to mount it to the camera). I'll report back as soon as it turns up. The product is called a 'jelly lens' and they are designed for use on a cell phone - search ebay for "jelly lens wide angle" and you will see a number of them on there.

Hi TM,

I spotted this web page on the DVK808 camera and it contains some of the most technical info available for this and many similar cameras.


May 27, 2010 | Unregistered CommenterAmbrose

Ambrose - that link is brilliant. I'll be sending everyone there who asks for help in future. There is a mountain of stuff to read - i'll be studying it in detail (I've spotted that he already suggested the jelly lens as a wide angle option).

how much a keychaincam cost in indian rupees.what payment options are available

June 26, 2010 | Unregistered Commentersree

The unit is widely available on eBay and the payment method there is PayPal which I believe is fairly universal!

June 26, 2010 | Unregistered CommenterAmbrose

Here is an overview of the different types of 808 camera's:

July 9, 2010 | Unregistered Commenterruud

Looks like they've come out with a new look for the keychain cam. Looks nice.

(no connection to ML, just a happy customer)

July 29, 2010 | Unregistered CommenterAmbrose

I've seen a couple of different keychain type designs, but this one has sound activation so must have different circuitry to my DVK808.

I've got another larger 'spy' camera to test out as soon as I get a few hours to myself. I'm hoping the (slightly) larger lens captures a wider angle than the keychain one. A review will of course follow.

July 29, 2010 | Unregistered CommenterTechmoan

This review is one that I need. This really shows how amazing that spy camera is. I am also hearing a lot of good thoughts about that spy gadget and I think I should get one now.
