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%!

Vico Marcus 4 Cinemascope Dash-Cam REVIEW

Here is my review of the Vicovation Marcus 4 car camera. One thing that sets this camera apart from others I've tested is its unusual Cinemascope-esque 21:9 ratio 2560x1080 video mode. It may sound like a gimmick, but it actually makes a lot of sense. Watch the video below to find out more. 


As I feared, the youtube re-encoding has introduced a a lot of blocking artifacts into the video samples I show in the review. It's especially noticeable in the first shot where I talk to the camera whilst the car is driving under the trees. If you want to see the original quality of this clip, it's one of the ones I've uploaded in the 'Downloadable Samples' link below. (Filename is '1080p30 Day').

Hi Mat, great review as always, full of detail. This one doesn't really do it for me though, I think the bulky design and the price put me off to be honest. I'm still patiently waiting for the next generation Mobius camera - if there is going to be one.

Thanks again

September 16, 2014 | Unregistered CommenterDaz

I haven't heard a peep out of the Mobius guys since well over a year ago.

September 16, 2014 | Registered CommenterTechmoan

Hi! I did enjoy your review as usually. Pitty I dont need a dash-cam. : ) Are you plannig an SJ 3000 rev? I would be quite interested.

September 18, 2014 | Unregistered Commentertrakac

Will you be reviewing the Marcus 5 the Dual Cam from Vico?

September 18, 2014 | Unregistered CommenterMatt

I was wondering which car DVR camera's are able to have the recording flipped to be mounted on the actual dash instead of the windshield. There are places in the states that it is illegal to have things mounted to the windshield.

September 18, 2014 | Unregistered CommenterJames C

Jamec C,

A lot of the cameras reviewed have that option. Matt usually indicates if that option is present in the camera. Even if not, you are able to flip the video with any video editing software.

The 2560x1080 looked damn near perfect on my 30" monitor.

September 19, 2014 | Unregistered Commenterbri

Looking forward to the 5 dual. It's about time someone did a dual with a rear facing with a reasonable resolution.
I don't know how much their GPS mouse add on is but I bet the cheap USB GPS antennas that you can get off eBay will work just fine.
I'm also surprised that Vico don't do the Vico player software for the Mac. That would be a big plus for me.

I'm currently running a TF2+ in 1 car and a G1W in another. Just noticed that there is an update for the TF2+.

September 20, 2014 | Unregistered Commenterevilution

Hey there, regarding the 2560x1080 resolution, the reason why you had that sorta image is due to not having a 2560x1080 monitor, I own a 2560x1080 21:9 screen and looking at the raw footage fills my screen as expected, these are called superwide and you dont really get the top and bottom cropped off that much compared to what Ive seen here. You get a much wider FOV with no fish eye effect, if you ever get hold of such a monitor and they are more widely available now, you will love it :).

Amazon and overclockers uk have such screens.

September 24, 2014 | Unregistered Commenterabs

I *really* wish this camera had a time-lapse photo function as does the Mobius. It's the only thing keeping me from purchasing one. How about a word to the manufacturer?

September 24, 2014 | Unregistered CommenterDave

I think the GPS mouse from VicoVation will come in at around £18-19.

Amazon UK will be stocking the VicoVation cameras soon for anyone that is interested.

September 25, 2014 | Unregistered CommenterTerry

I buy the combo (M4 + GPS + CPL + Brackets) from
Amazing camera. Thanks for the review.

September 27, 2014 | Unregistered CommenterLee

I just bought the Marcus 4 and am having difficulty working out how to get into the individual menu functions
once i get the menu up
its not explained in the manual that I can see
any help would be great thank

January 24, 2015 | Unregistered Commenterarkay

Don't matter I got it figured thanx

January 24, 2015 | Unregistered Commenterarkay

Just purchased Marcus 4, When installing in Auto, Does Not turn On.

March 27, 2015 | Unregistered CommenterDave

I totally disagree that it is good for this camera to crop out the TOP of the video. That is how we get to see some of the most amazing videos of planes crashing and other amazing extended view shots around the world. Recording as much as possible.

April 13, 2015 | Unregistered CommenterWes

I have been looking for a dash cam with HD, GPS and all the other gizmos but very few support Mac use. I have been impressed with the Vico Marcus 4/5 - can you tell me if this is another Windows only product please.

April 30, 2015 | Unregistered CommenterTrisha

No PCs were used in the making of this video. I use a Mac to make all my reviews. Dashcams don't need any software unless they have GPS data that needs to be accessed.

April 30, 2015 | Registered CommenterTechmoan

I just bought this cam from Taiwan and tried it immediately upon arrival in Phil. The videos are really very good esp the night shots. You dont need to adjust anything from daytime to nighttime mode. I am happy that I decided to buy it

July 24, 2015 | Unregistered CommenterSteelman

Hi Techmoan,

Any comment on Marcus 2? Its specs look exactly the same as Marcus 4. The only difference I noticed is that 2560*1080 is not available in Marcus 2.


January 17, 2016 | Unregistered CommenterJack

Hi Techmoan

Purchased the Marcus 4, but have had to return the item. When used in the park mode, the power outlet in my car, switches off after approximately 20 minutes; as the unit has no batteries, "no video". Shame really, as it seems like a good dashcam.

March 22, 2016 | Unregistered CommenterBarrie

Barrie, you need a Vico Power plus or an iroad power linker, these devices will power the Vico while the ignition is turned off allowing the use of the "Smart parking mode" made a big mistake sending it back without researching the smart parking mode first.
