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%!

SJ1000 - At last...a good cheap action camera 

After years of fruitless searching and a not inconsiderable amount of money spent, I've finally found a good, cheap, 1080p waterproof action camera.

I get a lot of emails from people asking what action camera I would recommend for occasional use for paint-balling, mountain biking, etc - that costs around £50. Prior to today, my response has been that the cheapest camera I could really recommend was the Liquid Image Ego, but it costs£100.

If your budget doesn't stretch to £100 then there are very few action cameras to choose from. Perhaps the best camera from a very short shortlist is the the RD32II, but it suffers from a substandard mounting system and a non-standard video format. 

The SJ1000 changes everything. For about £60 you can buy a camera that is capable (under the right conditions) of producing video that rivals cameras costing over four times as much. I'm not suggesting that people throw away their GoPro HDHero 3 Black Edition cameras and get this instead...but if you are on a limited budget or don't see the point in spending £200+ on something you only plan on using a couple of times a year then this might well be the camera for you.

You'll have to do a bit of experimenting to get the mounting options to fit your requirements, but it's definitely worth the trouble when you see the video quality that you can get from this small camera.

Here is a folder of downloadable sample clips

I should mention that I haven't shot many 720p60 clips...and you'll only find 1080p on the bike.

The only thing I think that I forgot to say in the video was that when using it as a car DVR there is no gap between clips (as you expect nowadays) fact each clip repeats the last second of the previous one just to be sure.

UPDATE - 10 June 2013 - Answering a few questions.

First some bad news - The 720p60 mode turns out to actually be 720p30 (every frame is shown twice). I should have spotted this earlier, but I had only been testing the 1080p30 mode as that's the one I use. iMovie always converts 720p60 to 720p30 so that's why I didn't notice it before...apologies for that. Here is a link to a fast moving 720p clip I shot today.

Motion Detection mode - When this is on, the camera records 10 seconds of video and then stops until it sees another movement. If a movement occurs during the 10 seconds when it's recording then the timer is reset and it records for another 10 seconds. This way if the movement doesn't stop then the camera doesn't either....hope that makes sense.

The camera should be able to be mounted the right way up in a car if the correct mounts are combined....this is demonstrated in some of the ebay auction photos. 

File Sizes: 10 Minutes of video takes up 1.2GB in 1080p or 1.07GB in 720p modes.

The case floats in water and on it's own weighs 66.7g.

The camera itself is 7cm tall, 4.5cm wide, 3 cm thick at the bottom and 3.5cm thick at the top where the lens makes it deeper.

The timestamp can be switched off. I turned it off for the Night Time Driving clips and show this option on-screen 19:57 into the video.

I think the manufacturer may be a company with the snappy name of Shenzhen Hongfeng Century Technology Co. Ltd.

BATTERY LIFE is 2hrs 15mins (Could be 2hr 30 mins or more with the screen off)

UPDATE 29 August 2013 'NEW' FIRMWARE!

I know a few people have been waiting for this - so finally here is the updated firmware that fixes the screensaver bug. If the fact that the screen didn't automatically blank out wasn't an issue to you, I'd suggest skipping this update. If you want to update the firmware, you can download the file from the Files & Drivers Page. Updating it is very easy, but just in case you are's a quick video. Beware, if you somehow kill it, you are on your own.

Update 27 Sept 2013

Here's a link to another review of the camera by Tom Hardwick (he likes it).

Update 28/12/13.

This is a six month old review and a lot has happened since. You'll find the cases are improved, possibly the mounts too..and you now have the ability to turn the camera on when it's inside the case due to a different button arrangement. The current crop seem to have a 90º lens rather than the 140º on my camera. That means no fish-eye - but less FOV. I'm not doing any more videos about camera this but.....PLEASE READ THE COMMENTS...before posting a question that's been asked countless times before, it's the least you could do for all the kind people who have given up their time to elaborate on the features of this camera and posted their findings in the comments.  I'll give you a starter...NO IT DOESN'T DO TIMELAPSE...The way you can tell this is because there is no option for this on the screen when I go through all the menus in the camera...and it's the kind of thing I would have mentioned. I tend not to mention the things a camera doesn't do because we would be here all can't clip your toenails with this camera, it can't be used as a flotation device, it won't take x-rays etc.....

Just thinking aloud here. With no access to the on/off switch once it's in the UWH there seems little point in having access to the menu button and up/down switches and so on. Just set the camera running and run with it till it needs re-charging / re-carding. I'm pretty sure it's the UWH buttons themselves that are letting in water because the rear door is an excellent fit and I use a silica O ring grease.

Finally my SJ1000 is back from death world, I will now study how to make the case real waterproof.
If you guys are interested in underwater diving, I suggest you check:
for tips to maintain the camera

@tom hardwick thanks for the suggestion of the silicon grease I will definetely use it any suggestion on brands or shops?

Moisture can be a big fact too. My other UWH camera has lot of moisture after 2 hour in water (Bath) !

July 15, 2013 | Unregistered CommenterPat

@tom hardwick - The front glass/plastic of the UWH is still 22mm. diameter. Vignetting is still aparent!
I notice that the camera fits very snugly in the UWH - requiring a careful shake to remove it.
UWH buttons require quite a push to make contact and hence operate the camera switches.
Personally I'm not too worried about the effectiveness of the UWH, justs as long as it keeps out a drop or two of rain when using my bike.

thank you for another wonderful review. I wonder, is there anywhere I can get a spare battery? It comes quite handy when I want to capture lot of material, plus, batteries of course lose their capacity over time, so in time, I will just have to either change the camera or the battery, I would prefer to do the latter.

Following on from my earlier post today. I've noticed a couple of other differences from Mat's kit. On my UWH the back cover has additional plastic mouldings which look as if they've been added to stiffen it. This I imagine would improve the seal around the edge once it is under tension from the clasp.
Also the tripod bush on mine is slightly different, it is brass with a stopped threaded hole, whereas on Mat's it appears to be more like an embedded threaded bush with the housing plastic visible at the bottom. I don't know whether the useable thread is any longer though. Unfortunately they have also added a moulded lip around the case opening, presumably to stiffen the seal, however this now impedes a tripod thumb locking screw from seating against the bottom of the case as the surface area is now too small.
My kit is also missing the right angle balljoint (5.20mins in Mat's video). I don't know whether this is now normal or not. Have to agree about the quality of the fitting details, I think I will be loathe to trust some of them to hold the camera, I intend to adapt them and use mainly 3M Dual Lock strips/pads.

Will post more info. If I notice any more significant differences.

Thank you for the review! Your reviewings att Techmoan is very professional and maybe the best I`ve seen! Fantastic!
Some comments about SJ1000: I ordered one that arrived yesterday (ordered direct from Hongkong) and there are already some changes made since your review, on the underwaterhousing. On/off-button is reachable, reinforcements on the back and sides, and the buttons for scrolling is taken away from the housing. Sadly the reinforcements make it difficult to lock the mounting in the treads... Otherwise all mostly positive.

Can you share the manufacture contact with us? I will ask for a firmware update as soon my Sj1000 arrives.

I can't believe they want money for a firmware update, this is no sense, they need to learn customers relationship management.

July 16, 2013 | Unregistered CommenterRuy

As a further follow up. The one I received from Globalalibabahk (with UWH changes) is now being sold by Chinavasion and called
"Zenith", it shows the new housing on their site.

July 16, 2013 | Unregistered CommenterBargain Bob

@Ruy it was on the alibaba page of the company producing SJ1000 they deal with big distrubutors so they were asking for money if I would order 1000 pieces would be reasonable.
I think for everybody who has previous firmwares they should contact their sellers. I believe is the best option for this poorly supported products.
