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 RD32II 1080p .h264 Sport Cam



This video took a lot longer than I anticipated, but here it is. I've uploaded part 1 in 720p and part 2 in 1080p. This was to avoid oddballs asking what was the point of doing a 720p review of a 1080p camera (as happened with my Extreme camera review). However this isn't really a solution to the problem because Youtube's 720p and 1080p video both bear very little relation to the footage that was originally shot by the camera.

I've converted the video and then editied it and then converted it again and then uploaded it to youtube which converted it again - you can therefore appreciate the fact that the footage you see on youtube doesn't really do justice to the quality of the originals. For example, the Youtube clips start off jerky and then smooth out after a few seconds...the originals of course don't do this.

This isn't a unique problem, if you read any photography magazines they are reviewing multimegapixel cameras and printing credit card sized sample shots on low dpi paper. Car magazines don't let you test the car out, AV magazines try and describe sound quality etc etc.... So like those examples all I can really do is give you an indication of the quality, not a direct demonstration of it.

As I mentioned in the video - the .h264 avi files created by this camera could not be imported into my iMovie so I had to spend a day converting them using MPEG Streamclip into .mp4 files. This was a major inconvenience and something that will probably stop me from using the camera again in the future. Now I'm using a Mac with iMovie. I haven't tried these in Final Cut or any PC editing package, so they may import fine into other editing packages.

Downloadable Test Clips

Therefore  to enable you to test out the original footage from this camera with your own editing packages or just play back some unmolested clips - I have uploaded a few short clips. These are all 1920x1080p 30fps clips you can download them here.

If you just want my opinion and all you want to do is film clear sharp HD footage and don't want to edit it on a Mac in iMovie, then I would strongly recommend this camera. I know that I mentioned the footage had a blue tinge, but unless I had put it up side by side with the Extreme cam, I don't think I'd have noticed it and I also wouldn't have noticed how much more vibrant the colours were on the RD32II either. The footage is very smooth without a dropped frame in sight and the sound quality is totally acceptable for a camera of this sort.

More Info

If you want to see the Camera on the Manufacturer's page here is a link. You can look at the specifications here, which tell you things like you can fit 41 mins of 1080p or 720p 60 video on a 4GB card, the recording battery life is 2.5hrs (it's 1.5 with the torch lit at the same time), charge time is 3 hours and the camera weighs 86g.


I'm really taken with the 5MP fisheye photos too, they can turn out surprisingly well. My technique when taking a photo is to take four or five shots of each scene, pointing the camera at a slightly different angle each time. When I get home I download the photos and choose the best framed picture of each scene. It reminds me of the days of getting films developed and hurriedly flicking through the envelope of photos hoping that I managed to get a good shot or two - but without all the expense. I've uploaded a gallery of photos from this camera here.

Where can you buy one.

I've seen this camera on sale for about $145 or £90 including shipping (budget for import duties too) which seems a little bit high, although it's early days - something like £75 would seem even more right. Whatever you do though, don't get it mixed up with the original RD32, that one takes 720p mjpeg video and isn't a patch on this. Look out for .h264, 1080p and laser mentioned in the specs- and don't expect it to always be called the RD32II either. 

Places I've found selling this camera are below (Dealextreme also sell the mounting accessory pack).


Yellow Camera At Dealextreme 

Black Camera at Dealextreme

The Accessory Pack at Dealextreme 

Part 1 and 2 of the review are below - but view these full screen in HD to get a better idea, and don't try to view the 1080p versions on an old computer unless you have a fire extinguisher at the ready.



UPDATE: 15/01/12 Importing the Video into editing packages - For iMovie users, you may want to try out a piece of software that was suggested to me by a reader - FLVCrunch, an easy way to convert the files into MP4s which can then be imported into the Apple editing package. Also look in the youtube comments for people reporting back with their results when using other software - the clips from this camera are reportedly working fine with Windows Live Movie Maker, Adobe Premiere and Vegas 9.0b.

UPDATE: 17/01/12 I've had a few requests for downloadable 720p 60fps Clips - which is understandable as youtube can only display 30fps as can my editing package. So is a link to a single clip (24mb)....and here is a zip file containing that clip and another five as well (173mb). If your computer is anything like mine, you may only get the full 60fps effect if you view these full screen. 

UPDATE: 01/03/12 Dealextreme now stock this camera & The Accessory Pack (Essential for mounting it to things other than a bicycle) Links have been added to the sellers section above.

I do enjoy your reviews !
One question concerning the RD 32 11, specs claim to be waterproof but the card slot and usb appear to be open. Are they ?

April 20, 2012 | Unregistered CommenterArt

@art The slots are covered by the round plastic can see it somewhere in the video.

Techmoan, having had the camera for a week or so and being very pleased with it, I could do with a simple video editing software package. What would you recommend? I have a PC (not MAC) and I'm just looking for something very simple, ideally for free. Thanks. Rob.

April 22, 2012 | Unregistered CommenterNotlob Rob

@Rob unfortunately I don't have a clue about PC editing, I've only used iMovie on the Mac for years..hopefully someone else can help you out by commenting on this..

April 22, 2012 | Registered CommenterTechmoan

Doesn't Windows have Movie Maker any more?

April 22, 2012 | Unregistered CommenterVoyager03

Magix Movie Edit Pro MX~ About $100 but worth every cent. Will have you making great shorts in no time. I've used their Music Maker for years- all of their programs are drag and drop. The new MX designation means it is now really easy to use media from one MX program to another.

April 22, 2012 | Unregistered CommenterRob

@Voyager03 Thanks for the tip. I was completely unaware of this programme. It seems that it's been superceded, but there's a more recent (free) version that seems to fit the bill. Thanks!

Hello Techmoan!

Thank you for doing the review on the RD32II.

I would like to know who makes this device.
I am looking at getting one for myself and might redistribute within the UK.

Here's a link to the manufacturer

April 23, 2012 | Registered CommenterTechmoan

Hello Techmoan!
I bought the rd32ii, and I want to know if there is a new firmware. Because I want to take pictures as the continuous gopro (1 picture every 3 seconds). Is this possible. Thank you for your response.

April 24, 2012 | Unregistered CommenterJeanbar

Unfortunately I don't know anything about new firmwares for this camera. You could always contact the manufacturer and ask them. Let me know if you get anywhere.

Thank you Techmoan for your reply!

I ordered on last night and it is on it's way!

@ Rob
I tried several Windows video editing programs looking for something that would handle both 1080p 30fps and 720p 60fps. Many of the windows programs will not handle 60fps (including some of the top rated ones that cost $$$).
I finally settled on NCH VideoPad. You can download a two week trial version and then switch to a free version when the trial runs out.
Titling and effects are pretty basic, and the transitions aren't as good as some other programs. It does however produce very smooth 60fps output when played back on my HDTV. On some computers they don't play back smoothly, but that on a newer machine with a fast video card they are fine.
I'm still running WinXP and Windows Movie Maker is useless for this camera's output. It shrinks down the HD output and coverts everything to 30fps.

April 27, 2012 | Unregistered CommenterGreg

I could edit and save in different formats the sample AVI clip with Cyberlink Power Director (Windows 7). No problems.


PS very good review!

What type of battery this camera has? Can i replace the battery if the one available inside the camera gets damaged

April 30, 2012 | Unregistered CommenterAjith

Dude you are the man! This review was great. This camera is exactly what I wanted. I am going to use it to take some surfing and skiing shots. Let me know if you want me to send you some sample videos from the water!

Hi Techmoan,

Firstly I'd like to say thanks! I had almost ordered a bullet cam which I dont think I would have been happy with and stumbled upon one of your reviews by accident. It was very helpful! It must take a lot of time for you to carry out your reviews, edit the footage, upload etc, so thanks!!

Originally I ordered based on your review on youtube (It should be here next week) but have just looked at your clips uploaded here. It just left me with a question ... after looking between the 720 60fps clip and the 1080 30fps clip it seems as though the 720 clip is more Fish eyed? Is this an optical illusion of the curved building in the clip, or does the 720 footage have a more curved look to it?

Thanks in advance

May 15, 2012 | Unregistered CommenterSimon

@Simon. No your eyes are not deceiving you. The 720p mode has a wider FOV than the 1080p mode.

I suppose it's good that you can have the choice, sometimes the wider angle of the 720p mode is useful....I used it in my recent Toyota IQ review

Took it SURFING! Works great!!

Thanks for the awesome reviews!!

I'm still can't get a good edit for my videos.... I'm using "Hamster Free Video Converter" and it help me only to reduce the size, but when i converted them in MP4 the Sounds get Distortion and sound still come first than the video....
Anyone can suggest me something to solve this? or knows any other better program to edit the videos?
Thanxs in Advance.

May 20, 2012 | Unregistered CommenterCarlos

Zac (March 5, 2012) mentioned using ffmpeg binary in the terminal to produce a video file acceptable by iMovie. This works and probably will be handy for other cameras.
To get the 64 bit binary go to and choose the latest release.

You only need 'ffmpeg' binary in the 'bin' folder which you can drag and drop onto a terminal window then supply the argument ' -i ' followed by 'source.avi' then ' -vcodec copy ' then 'target.mp4'

ffmpeg -i ~/Desktop/input.avi -vcodec copy ~/Desktop/output.mp4


If you've got plenty of hard drive space I suggest using an intermediate codec such as Apple Intermediate Codec, Cineform or Apple ProRes. Convert the source files with MPEGStreamclip to quicktime movies using intermediate codec compression. They keep the quality but reduce the work the processor has to do at the expense of disk space.

You could let iMovie do the compression to h264 or export the final edited movie using 'export using quicktime' with settings 'intermediate codec compression' then letting MPEGStreamclip compress to h264. The higher the quality of the source video the more apparent the benefits of intermediate codecs.

Possible workflows:
h264 -> iMovie -> h264
h264 -> MPEGStreamclip -> Intermediate codec -> iMovie -> h264
h264 -> MPEGStreamclip -> Intermediate codec -> iMovie -> Intermediate codec -> MPEGStreamclip -> h264


iMovie comes with Apple Intermediate codec.

To get Apple ProRes 422:
(ProApps QuickTime Codecs v1.0.1)

You can install these codecs whether you have FCP et al or not. They can be extracted from the package file with Pacifist or UnPkg, and then move AppleProResCodec.component to ~/Library/QuickTime.

UnPkg available from

To get the GoPro CineForm HD codec download the free Cineform Studio for Mac:

Hi Techmoan,
Thanks for your reviews! Nothing like impartial info on these cheap Chinese products... what is wrong with me - I downloaded your .zip file of samples but find they are all 6: 1920x1080, 30fps??? very odd as others here did get 720p - have you updated the download again? has it reverted?
I wish to use the camera in water sports and that is where the float info is great (posted above) and looking at your sample of flowing water over most of the frame it was not that well handled - insufficient bandwidth for 1920x1080 - obvious blocking. Is 720p 60fps better in that regard? Sample?

I notice Redleaf have introduced a new camera the RD37 that sounds like the RD32II with an LCD screen added, moved the USB/HDMI connectors so they don't interfere as well - maybe they fixed the problem with a dodgey audio stream in AVI that was breaking iMovie as well? Currently the prelim spec has them dropping 720p/60fps - hope they don't! Are you going to look at this camera? - might address all your criticisms! Seen under USD 130. Hopefully they send you a freebe.
PS quote from review of RD32II on DealExtreme: How-to successfull edit footage with minimal reconversion:
use Avidemux from and replace audio stream in avi contaner to stereo mp3, for video stream just leave "copy" and voila - all programs work with footage seamlessly; also you can cut and merge footages from cam without recoversion, before importing in serious video editing software. After replacing audio stream SONY Vegas 9,10,11, Corel and even VirtualDub work flawlessly.

May 26, 2012 | Unregistered CommenterEric

@Eric I think you might have missed the separate link to the 720p files further down in the article

I'm not sure that the 720p mode will perform any better for you, it's still a pretty low bitrate.
I haven't got any plans to look at the RD37 at the moment and haven't been in touch with Redleaf since they sent me those three cameras some time ago now.

I sorted out my editing issues by using FLV Crunch for the Mac, a piece of software someone recommended to me - I just drag and drop and the output files can by imported into iMovie with ease. I used the RD32II camera attached to my head in the recent IQ/Smart comparison, and it worked well now that I can actually edit the files from it.

May 26, 2012 | Registered CommenterTechmoan

@Techmoan ooops, yes missed later zip file. Thanks! I notice these files have AAC audio whereas the original samples have ADPCM audio - presume they have been post processed by yourself.

Specs for RD37 are 48khz AAC audio so it looks like they have fixed that problem. I decided to order the RD32II as I need 60fps and the waterproofing on the RD37 looks very flimsy. The RD32II has to be better than my POS 1st gen camera from the company that complained to you about the Redleaf metal bullet camera review. That camera claimed 720p/30fps and is actually upscaled 360p and drops frames all over the place.

Annoying Redleaf did not spec the FOV in 720 mode - I deduce they are using the centre of the 5M CMOS sensor (guessing its 2560x1920) for 1080p and using 2:1 scaling for 720p mode for extra sensitivity - if that is the case then my math says if 1080p is 120 deg then 720p will be 133 deg - think that looks about right - which is exactly what I want. Using only part of the sensor allows that other company to do their digital motion stabilisation in 1080p mode.

One final suggestion - when reviewing sports cameras please include handling of the sun coming into frame and close to frame as this will happen when the camera is mounted on a moving platform. The RD32II does not look very good there, based on the surfing Utube linked to above. I know you do not see the sun very much there...

May 28, 2012 | Unregistered CommenterEric

Hi Techmoan,

I admire your project. It really looks professional, in a good way. It is quite obvious your not trying to sell something, which is the best review one can get.

I wonder though, what are the companies involved in the design of the cameras saying about the copies sold in China? Perhaps they don't have the rights for the design, or maybe they just can't do anything about the outlet. I am thinking about Rollei for instance, who sell -, or until recently at least - sold the Rollei Action Cam 100, which obviously is identical to the RD32 camera.

Have you heard anything from them, or do you know anything about claims from their side? What do you think about promoting copies, who might be illegal? Do you know if they are illegal?

It is not a critic of your work. As buyers of the chinese cameras at the prices offered, we can surely claim to be in good belief, if someone told us afterwards, that we are buying copies. They certainly don't have to be copies.

Keep up the good work. I wish there were more people like you making such good reviews.

Best regards

Grazie tante per il tuo utilissimo lavoro,tanti saluti,Ciro.

Hi! Thanks for your review. I' looking for the cam to be used for FPV (RC-flying with onboard video). Question: It seems that RDII is supporting motion detection. the old one did too but after 10 min. of waiting, the camera turned off - is it the same with this cam? cheaper version you can find on

for those that want the stripped down version for RC flying, its in stock at Hobbyking.
