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 ACT20 Action Camera

My review of this camera was negatively coloured by the fact that I couldn't edit or convert the footage using my Mac.  I edit all my Youtube videos using iMovie on my Mac and not being able to properly utilise the original footage from this camera meant that I couldn't do an accurate video review.

There is definitely something non-standard about the .avi files created by this camera - however after I posted this video review, I tried editing the footage on my PC in a trial version of Power Director 9 and it worked without a hitch. 

So unfortunately this camera is still not ideal for me - but if you use a PC as your main machine, this camera might possibly be just what you are looking for.

To me, the main headline feature of this camera is the fact that it can record for 3 hours on one charge. The HD808 can only manage about 45 mins and then often stops recording after only a handful of minutes (for reasons that I really can't determine). If I ride my motorcycle to work it's a 2 hour round-trip, so for the moment I'll be using the ACT20 as an incident camera - attached to my helmet. I'll set it to loop-record continuously (in 20 min segments) and I'll only pull the footage off the camera if I need to use it for some kind of evidence.

I think when I make my next video review when my new action camera arrives from Dealextreme, I'll give the ACT20 a bit more screen time to redress any disservice that I may have done to it in this video.

UPDATE: I've decided to add a brief clip below of some car footage with the original soundtrack intact so that you can get an idea about the camera's sound quality. I've also noticed that this camera drops a heck of a lot of frames. From my examinations, some seconds of video only consist of 21 individual frames with the other 9 frames being made up of duplicates. So if you notice the video stuttering or think that the motion seems unnatural, this is the reason.

@Casper It's getting a bit long in the tooth now, so I won't be getting one. There are quite a few reviews and samples on Dealextreme.

My recording seems to go off after like one cycle. It does not record continuously which is what I needed. Any recommendation to fix this issue?

just received the new model ACT35, but it records only 5 minthen stops.
I use a class 10, 16gb card.Any advice?

December 15, 2012 | Unregistered Commenterovilost

Great review, what would you recommend for hunting 60 or 120 degree?

February 3, 2013 | Unregistered Commentergk

I have given up on my ACT20 which virtually shuts down after the first recording segment, i.e. 20 mins block. Since then, I found better luck with SJ72 HD Action Cam and made a fair amount of recording tests.

Results are on my Youtube channel for sampling purpose. Latest is a night test as a rear view cam - leave me your feedback there.


February 17, 2013 | Unregistered CommenterPatrick

Hi Pat,

I think you have a faulty camera. Can you confirm the card you are using is at least class 4 and more than 2gig?

I had a similar issue, however found out that the card I received was a fake (not from company, brought interdependently).

Depending on how old the stock was that you received, you might of got one of the earlier versions, there is a firmware update you can try, however I would try and return it under warranty.

I would suggest checking out their latest model of the ACT camera range, it is a very nice helmet camera, little bit thicker than the ACT, however brings it more on par with what is released at present.

I am using both the ACT20 & ACT40 on my fire helmet.

February 17, 2013 | Unregistered CommenterMichael Allen

Hi Michael,

Its confirmed that the 16GB Micro SD card (Sandisk Class 10) is authentic. Anyway, I have moved to the SJ72 which works flawlessly as my latest videos in Youtube evidenced.

I will consider your suggestion for my second cam (ACT40) and once again, thanks for the kind thoughts.

Hi, I am just wondering how to stop the camera from recording 20 min and then stopping, or can you?

April 22, 2013 | Unregistered CommenterJames

update firmware !!! I have also this problem. After update firmware all right.

April 23, 2013 | Unregistered Commentervitaliy

Hi vitaliy,

Where did you get the firmware?

April 23, 2013 | Unregistered CommenterPatrick

Also Make Sure You Have A Real SD Card With More Than 2GB Storage & At Least A Class 4 Or Higher.

The Camera Saves The Files In 20 Min Segments, Make Sure You Have Enough Room On Your Card For More, I Can't Remember If 20 Min = 2GB or 1GB, Mine Is On My Fire Helmet So I Can't Check At Present.

Is it possible to increase the lens angle?

April 29, 2013 | Unregistered CommenterJames

ACT10 no, ACT20 came in two flavours 60deg and 120deg lens. I know my ACT20 was the 120deg version I could change the res from 1280x720 (30FPS) to 1600x1200 (15FPS) the 1600 res does allow you to see more. The new model the ACT40 uses the GoPro 2 lens and has a 170deg view angle. Hope that helps.

Hi my friends,
After long time stop, my ACT20 don't charge the battery....
Someone help me?

Best Regards

Try connect USB cable for long time: 3-4 hours.

May 12, 2013 | Unregistered Commenterkucha

Hi everybody

Is there any way to load an icon in the center of the screen during the recording?
I want to mount the camera on a shotgun and it will be very helpful to know where is my aiming point the video.
Does the firmware supports this, or is there anyway to do it through the setup.ini?


May 16, 2013 | Unregistered CommenterMarinos

Kucha, I connect to USB-cable for 5 hours, and when i disconect the cable, the camera don't turn on.
Anybody have the problem?

May 16, 2013 | Unregistered CommenterDaniel

"After long time stop, my ACT20 don't charge the battery...."
How many long ???

May 16, 2013 | Unregistered Commenterkucha

@Marinos, No sorry not in the firmware or setup file, the only thing you could do is overlay a bmp (bitmap) file after the video is captured using Virtual Dub, just create a cross-hair [ + ] image then overlay it as a watermark.

@Daniel, I suspect you might have a faulty camera, best way to test it though is to use another USB cable and charge it via the computer / wall charger, use both just to ensure you are getting enough power, I tend to use the wall adapter the most. Also try the reset button once charging. Have you tried holding down the button, not just the power button, do you get any lights show up?

It will operate normally connected to power, however when disconnect the power it not holds charger and turn off.

Does anyone know why my time on the screen is not updating? I have deleted the text file and created a new one and still the year 2011 is showing up on my videos. I have also reformat my memory card and reset my device yet the date is not being updated. I have recorded without the time.txt file yet my videos still show a date of 2011.

February 6, 2014 | Unregistered Commentereddie


Are you sure your creating the file correctly?

Is this an ACT20 you have?

Try this, copy the program onto the cameras card and run. It should allow you to adjust settings as well as create the time file.

February 6, 2014 | Unregistered CommenterCyberCitizen

I have this camera but it only records for about 1 to 1 1/2 hr max when it's been on the charger all night. Anyway to get 2.5hrs of video recording as claimed? maybe something in settings?

April 8, 2014 | Unregistered Commentereddiee

I've recently an ACT20 ( branded as Campak ) and experiencing VERY jerky recordings,sometimes freezing for a couple of seconds ( audio is fine ) i've tried various SD cards inc. Sandisk, Kingston etc from 16gb - 32gb. The only files I see available are DCIM and TIME.
when plugged into PC or MAC.

I've also convertedthe recording to MP4 etc still to no avail.

As you can probably tell i'm a senior with nottoo much PC jurgon under my belt !!

Can anyone help please ?>?

TeddyS. If you just click on the setup.ini file it will probably open up the wrong viewing program. Try right clicking and choosing to 'open with' notepad or wordpad instead.

I use the ACT20 with 120degree and did record in CycleRecord and nonCycleRecord mode on a 8GB Sandisk Class 10 card. In both modes I got 4 avi files (3 files with 1,96 GB 20min plus 1 file with 366 MB 3:36min). The max battery time is about 3,5 hours which would theoretical fill a 32 GB card. Did anybody test such a size on the cam, as 16 GB is stated as maximum in the documentation.

June 10, 2016 | Unregistered Commenteresthetique Tunisie

hello. i have this cam ACT20 (ebay, $73, some month ago).
But it is work bad. I have problem: only recording 20 mins at a time then stopping and turn off. I have also card class 10 16Gb. Also i try card 32Gb. If I stop recording less than 15-20min, then files wrote on flash and i can see them.
i download your firmware, run, and I see "connect device - 0", can select firmware file, but button "SETUP" is not active. Why program dont see camera?
