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%!

Taxi Cam - Dual Lens Rear-View Mirror Car Recorder

One of the more common email requests I get is to do more reviews of rear-view mirror car cameras. It's not for want of trying, but this particular sector of the 'dash-cam' market seems to be particularly under represented. Most of the cameras currently on sale have similar out-dated internals, use the old MJPEG codec and offer (upscaled fake-hd) resolution of 1280x960. 

For this video I managed to find an h.264 camera that is supposed to offer 1080p, has rotating cameras which makes it suitable for both left and right hand drive vehicles and importantly if it's to be used as a Taxi-cam has IR leds that point inwards. Watch the video below to see how it fares.

Hi Mat, great video, surprisingly expensive this one, bit bulky for me, but I do love the idea of dual cams, had one myself for years.

Great stuff

As always thanks for listening

Hi mat,

This rear mirror is very normal for us,as we are dash camera manufacturer, the rearmirro has other cool feature: 1. it can receive calls and make a calls use voices, 2. it has GPS navigation. 3. It can connect with weixi app in china.....

This product is our A201 rearmirror ( chinese model name). So the rear mirror you review is very normal for us.

Haven't watched it yet Mat, but that's a cracking pun - see how it fares . . ;)

Hi Mat. Another fascinating video. Not a product I am likely to buy any time soon though. I already have front and rear facing cams, but I rarely carry passengers, and have no desire to see their antics on screen.

The same goes for me.

Recently returned this camera.

Even on a cloudy day, the white balancing was bad. Couldn't see anything out of the rear window, and the front was just "meh" quality

April 16, 2015 | Unregistered CommenterDavid

Yes mirror cameras aren't really designed to see out of the rear of a car. They'll just show the interior. That's why I'm referring to this one as a Taxi Cam.

Blackview DOME also have car Rearview at

One TINY (maybe) plus is that you could angle both facing forwards and get them to just overlap in the centre - Wide angle without having to see too much sky - esp maybe in low res mode. It's the biker in me thinking aloud. SMIDSY

I found the lens needs to be 2.1mm to obtain the angle needed, its no good seeing half a car, it looks ok but let down by cheap parts
