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%!

The Waterproof Nautilus WiFi Mini Camera

In the video below I review the latest budget mini camera from the people behind the 808#26 keyring camera. It's called the Nautilus cam (good name that) and the camera itself is waterproof to 5m without an additional case and has WiFi connectivity.

Hi Mat,

Isn't this "nonstandard" USB blug actually a UC-E6? It can be found on e.g. Nikon cameras. If you google for images, it looks like pretty much the same.
Of course, it is still more rare than the micro USB.

July 20, 2015 | Unregistered CommenterRelakS

Also succumbed to amiibos, I see ...

July 20, 2015 | Unregistered Commenterchorondus

Would you say this is a good alternative to the Mobius camera? I'm thinking in terms having it as a black-box recorder for my cycle commutes in Central London, and the significantly lower price is compelling draw.

July 21, 2015 | Unregistered CommenterJ.R.

It looks like an improved Mobius, except for the video quality. And they missed it again: I wish it would film sideways, I mean, I would like the lens to be 90 degrees off axis, so I would just "velcro" (using 3M Dual Lock) the camera to my helmet. No need to craddle then. And that non standard cable is a joke.

July 21, 2015 | Unregistered CommenterAndy Colla

Dear Mat
Thx for your nice review. Why is this camera cheaper than 808 #26 about 20$?
It's water-proof, has Wifi, and the quality's the same I believe. So why?

July 21, 2015 | Unregistered CommenterPedram

Regarding the non-standard cable. The manufacturer has stated that future productions of the camera will feature standard micro USB cables.

July 22, 2015 | Unregistered CommenterGeoff S

Andy: The camera is probably cheaper than the #26 because it supposedly shares the same internals as the #26, which are somewhat old and make it cheaper to produce. The question is: why hasn't the #26 come down in price? I've noticed that many of these cameras never come down from their original release price. Maybe they're produced at a fixed price and they don't want to lose money by burning off inventory. Who knows, but I wouldn't be too worried, the HT-F1 camera is half the price as the 808 #26 and it's also basically the same exact thing.

Mat, I'm guessing you haven't opened it up to check how it's made, but I was wondering how it is doing regarding heat. Does it get hot while recording or browsing the SD folders via USB?

I have a #26 V1, which uses the OmniVision OV2710 CMOS Sensor and iCatch SPCA6330A Processor, both get very hot, but at least the metal body helps.

The Mobius, HT-F1, and my A118 Dashcam all seem to share the Aptina AR0330 CMOS sensor and Novatek NT96650 processor, all of which also have some heat problems.

July 22, 2015 | Unregistered CommenterMike

Thank u for your answer. My source for the prices would be the original website of the maker :
Yes 26 doesn't seem to be getting cheaper much, but I really can't figure out how it's more expensive than nautilus.
You mean to say that water proof case and wifi make a camera not only more expensive but also cheaper?
You said your 26 is v1. Are there other versions of 26?

July 22, 2015 | Unregistered CommenterPedram

Ah, I got your name wrong, I was looking at the post above you.

Now that I can see they have a website, this gives me a little more insight. I didn't know they were responsible for the Innov cameras. The V.1 is the #26 that everyone is familiar with, metal body and a Single LED. The V.2 is ugly, I'm not even sure if Hetai is responsible for it, but here's a look: Link. If you saw Mat's video, the original name for the Nautilus was going to be the V.3.

Here's some speculations as to the price.
It seems to me that the Aptina AR0330 CMOS sensor is often paired with the Novatek NT96650 processor. This may also be a cheaper combo. A lot of Dash cams and the Mobius cam has this combo.
The #26 V.1 has a OmniVision OV2710 CMOS Sensor and iCatch SPCA6330A Processor. This might be the more expensive combo. Better is subjective, I don't know which produces better quality.

Some assumptions, the following cameras seem to use the Aptina/Novatek combo:
Hetai: C1/C2/C3, HT-F1 (confirmed, I have one), the #26 V.2 (AR0330 mentioned in ebay description), DR32 (guess)

Also using the Aptina/Novatek:
Mobius Actioncam, and the A118 / B40 Wedge Dashcam (Which I use in my car)

The Omnivision/iCatch combo:
The #26 V.1 (I own one) and the Nautilus (mentioned OV2710 on Hetai's site)

Why the Nautilus is so much cheaper is beyond me, they are basically the same camera, and the Nautilus has WiFi. My speculation is in the actual casing. The #26 V.1 is very well made, IMO. The entire body works as a heatsink for both the CMOS and Processor, which both get very hot. I found that the HT-F1 also gets extremely hot, but since it's made of plastic, the components get heat soaked and it freezes up.

July 24, 2015 | Unregistered CommenterMike

Mike how long exactly could u record with 26 v1 on a full charge?

July 25, 2015 | Unregistered CommenterPedram

Pedram: It works pretty much as advertised, about 40 minutes on a full battery. You do have to replace the battery after a couple of years, I got down to a 5min run time with a battery that wouldn't hold a charge, any more. I think the heat had some effect.

Using the special cable it comes with, you can run off of an external battery for as long as you want. A 32GB card will give you 4-5 hours IIRC. Again, with the heat. After about 10 min of continuous use, you will notice a reduction in color saturation, contrast, and bitrate. Unlike the 720 cams, every 1080 cam I've used generates a ton of heat from the CMOS and Processor. They eventually get heat soaked, but at the very least, the #26 handles this the best by having an all-aluminum body,

How about "autostart / autostop" (with start/stop recording) function in the car ? (when power is turned on/off)

September 11, 2015 | Unregistered CommenterOleg


love your videos. I bought the Hetai Nautilus through one of your links. I have charged it but it won't power on. If I use the USB to plug it into a PC it finds it but still the buttons don't work.

Am I doing something wrong? Do you know the device support forum?


February 24, 2016 | Unregistered CommenterTheo

Pressing the buttons whilst it is attached to a computer won't do anything because it is acting as a memory card reader.
You say you charged it...there are two things that could be happening.
1) the battery has failed
2) you didn't charge it...but it looked like you were charging it. By this I mean, did you attach it to a 1amp to 2.1amp USB charger plug and plug it into a wall socket, or did you just plug it into a PC USB socket, these are usually are only 0.5 amps or less and therefore unable to charge the battery.

February 24, 2016 | Registered CommenterTechmoan

OMG a response from Mr Techmoan!! I am a wee tad flustered.

I do like your work/videos and the circuit around your village and that you respond in a timely manner too.

Ok, yes the thing has been on charge overnight via a Samsung mobile charger which is 2.1 amps. Is that a mistake and did I kill the battery?

I bought two of these and gave the other away as a gift. I have asked the giftee to check if theirs works and I should hear back tomorrow.

The folder structure of the memory card is:
which makes me feel the thing works as it has formatted the SD card.

If I plug it into power again I get a solid red light. If I press power for 3 ish seconds the power light starts flashing light red/bright red.

I feel I am doing something basically wrong. Does HETAI read these comments or have a support forum?

Thank you for your help so far.

February 25, 2016 | Unregistered CommenterTheo

It does sound very possible that you've killed the battery. It only needs to be charged for a few hours. I can't say for sure. By the way did you get two USB leads with it. I can't recall if it comes with a charging lead and a data transfer lead or just the one do-everything lead. It's been a long time since I did this video and I haven't had chance to watch it back.

February 25, 2016 | Registered CommenterTechmoan

Yes the battery does seem to be the issue but I am a novice.

I got three leads
1: 'special' USB out to RCA plugs
2: 'special' USB out to USB A male
3: 'special' USB out to a black and a red plug (two plugs) that the manual does not mention.

The 'special' USB to USB A seems to be a do-everything lead. My understanding was that a battery would only pull the ampage it needs during its charging period and that time connected etc should not matter.

Thank you for your answer.

I feel I may have a dud on my hands. Damn, I was really looking forward to this 'Nautilus' mini cam.

Lastly, do you know of any Hetai support forums?

February 26, 2016 | Unregistered CommenterTheo Faron

Mat - please don't take this as spam, but i won't be offended if you delete it. Just got this in my email - Banggood has these on clearance for only 30USD/21GBP! I remembered seeing your review a while back, so came to watch it again before pulling the trigger.

instead i think i'll save up for a Joovoo X-cam. same basic form factor as this and the mobius, but with modern internals. sure it costs a lot more, but you get what you pay for in this case. but if someone wants a cheap camera that's decent (out of the water anyway) this could be a good starter cam i suppose. I was thinking about putting this on my quadcopter, but i already have a Git2. sure, the nautilus form factor's better for use on a quadcopter, but the Git2 is SO much better of a camera.

May 16, 2016 | Unregistered CommenterGibson99


love your videos, very detailed but i still need to know what the best camera is to have on all the time while my car is parked,

for example, ive been using the mobius with the wide lens, capturing via motion detection on 32 GB sd card, i can capture over 40 hours of video time of this USB battery, i need to replace this camera now since the mojo water proof case lens failed and ruined my microphone, but i cant decide if i want to get another mobius or if its worth getting something with wifi since i frequently visit the car parked to swap the 32GB sd card, i was hoping wifi allowed me to monitor the car at a distance and or transfer the files wireless, but i dont want to spend hundreds of euros, cameras today are great at prices under 50 pounds so there must be something out there that beats the mobius by now.

Can you recommend anything?

May 31, 2016 | Unregistered CommenterMP

If you can hang on for a couple of weeks, I've got something you might be interested in. No spoilers, but just wait until you see this before you decide on your next purchase.

May 31, 2016 | Registered CommenterTechmoan


Thanks for the excellent reviews. I've been a follower for a few years now ever since the Mobius cam and have enjoyed each and every one of your reviews.

I purchased this camera based on your review and have not been disappointed. I use it for cycling. The water proof exterior that does not require a case is excellent for the tropical weather we have here in Singapore.

I'm trying to help decide on another camera for a cycling buddy of mine. It shall be used for cycling as well. We are trying to find something water proof or water resistant to protect against the weather.

My question is have there been any other good value cameras that are worthwhile considering that has this specific feature of not requiring an external casing to remain water proof or water resistant?

Thanks much for your help and I continue to look forward to the future reviews.

July 23, 2016 | Unregistered CommenterRizwan

I haven't noticed any new splash-proof cameras recently...however a number of the Sony action cameras have this handy feature, but they may be above your budget.

July 23, 2016 | Registered CommenterTechmoan

I've purchased this as a cycle helmet camera but the battery doesn't last very long. It dies in about an hour. Your video states an hour and 50 mins with WiFi turned off. How do you turn off WiFi? How can I get the advertised 1 hour 50 mins record time?

November 21, 2016 | Unregistered CommenterMil

Not sure if this video being tagged as coffee is a mistake or not? :)
