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%!

A Car DVR with a wired rear camera

My Car DVR reviews seem to be quite popular, so I thought it was time to do another one. It takes something a bit different to get my attention with so many similar car cams available. This model does have the interesting feature of an additional wired rearview camera. The fact that the camera is compact and pretty cheap also counts in its favour.  

I hijack the beginning of the video review to explain why it’s really not possible for me to answer the (hundreds) of email requests I receive asking me to recommend a specific ‘best’ car camera. This will also apply in relation to the similar requests I often get regarding action cams. 

I really can’t tell people what camera to buy, any more than a car magazine would try and tell you what car you should drive. These reviews are produced only to help people to formulate a decision based upon their own very specific personal requirements. Please also bear in mind that everything I test is only used for a short period of time, I have no idea about the long term reliability of any of the products I review. 

Overall though, this seems to me like a pretty decent camera for the price, despite one or two relatively minor niggles. I paid approximately £50 for mine from this seller on eBay who despatched from the UK. If you want an up-to-date list of auctions, you can click This Link which will perform a search on eBay UK for you.

Some of the other eBay sellers stock a grey coloured model and some also come with a different style of adjustable rear camera. 

I have also found it for sale on DX.COM where it seems to be supplied with an additional suction cup mount

As always there seem to be a few variations of this camera around - so take a close look at any example screenshots shown in any adverts. The menus in mine appear as a bar along the bottom of the screen.  Here's an example of one where the OSD looks completely different, and I have no idea how this one performs (It also comes without the rear camera).

Well the 2nd order arrived today and only took a speedy 10 days from ordering to delivering! It all looks good and seems to work ok, but I'll test it over the next few days, but so far so good. The other one was sent back so we'll see how long that takes. Just for info, it was about £10 normal delivery or £14 with a tracking number and signed for at the other end. I opted for the latter and that was through the post office.

Bought one of these on Aliexpress. It is 100% identical to the one Techmoan reviewed. I have put in a 16 GB Micro SD card, and it work perfectly, but now I got a problem. This morning on the way to work it said "Disk full" and shut down.

I cannot find ANY place to turn on the function to overwrite old files on the card, when it's full.

If it cannot do this, it's completely useless to me :-/

Any advice on this ?

Check in the settings menu (left top button, press twice). See what option is selected, 1 min, 2 min, 5 min or off.
Off means no recycling.

Eric: It seems to work. Now i just have that annoying problem that it records in 5 minute file segments instead of much longer files. It will be a pain to assemble all those video files if i ever need. Oh well, can't win every time.

Thanx for all the great reviews Mat, most informative.
just fitted one of these to my car, but i am confused with the rear cam view.
in your review, your rear perspective looks correct. Mine records a mirror image, and looks like i am driving on the right hand side of road?

I have found buttons to flip front image upside down, but i cant seem to flip the rear horizontally?
Anyone else had this?
Just for info, this one was from HongKong, via ebay seller "4coolday" there was no remote.

Hi! Once again I want to thank you for the level of detail you go to in your reviews. Truly amazing. Now, with that bit of business out of the way, I was wondering if perhaps you could confirm something for me. I'm in the US and was planning to purchase through I found two cameras that look like the one you tested, but the prices are significantly different (30 USD). I'm not sure if one might be lesser quality. I don't understand camera and video stuff and am embarassed to admit it. Can you possibly eyeball these briefly and tell me if the specs match the one you tested (either one or both of them)? The less expensive one: And the more expensive one:

Thank you for any light you can shed on this for me. I really want to get this one that you have reviewed and don't want to end up overpaying or getting the wrong product altogether. Returning products ordered online can be a real pain in the butt and these would have to go to China, it appears.

I'd go for the cheaper one. It seems to be the same model I reviewed based on the accessories. The more expensive one shows CarCam on a screen shot, which is one thing mine doesn't display.

Thanks for taking the time to look. As my '80s music loving friends would say, You rock, dude!

Kev - There definitely is a way to switch horizontally but can’t recall which button, try the mic button, you hold it down for more than 3 seconds, in fact just try them all, that’s what I did…. !
But are you certain there is a problem ?? I thought the same when I looked at it in my hands in front of me but when it’s in the car, facing back it is actually correct and OK.
If you do flip it I found it goes back to normal once switched off and on.

cyben76 - To be honest, looking at the quality of recording you have all ready I would stick with what you have.... these cameras are no better, no worse.
