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%!

A Car DVR with a wired rear camera

My Car DVR reviews seem to be quite popular, so I thought it was time to do another one. It takes something a bit different to get my attention with so many similar car cams available. This model does have the interesting feature of an additional wired rearview camera. The fact that the camera is compact and pretty cheap also counts in its favour.  

I hijack the beginning of the video review to explain why it’s really not possible for me to answer the (hundreds) of email requests I receive asking me to recommend a specific ‘best’ car camera. This will also apply in relation to the similar requests I often get regarding action cams. 

I really can’t tell people what camera to buy, any more than a car magazine would try and tell you what car you should drive. These reviews are produced only to help people to formulate a decision based upon their own very specific personal requirements. Please also bear in mind that everything I test is only used for a short period of time, I have no idea about the long term reliability of any of the products I review. 

Overall though, this seems to me like a pretty decent camera for the price, despite one or two relatively minor niggles. I paid approximately £50 for mine from this seller on eBay who despatched from the UK. If you want an up-to-date list of auctions, you can click This Link which will perform a search on eBay UK for you.

Some of the other eBay sellers stock a grey coloured model and some also come with a different style of adjustable rear camera. 

I have also found it for sale on DX.COM where it seems to be supplied with an additional suction cup mount

As always there seem to be a few variations of this camera around - so take a close look at any example screenshots shown in any adverts. The menus in mine appear as a bar along the bottom of the screen.  Here's an example of one where the OSD looks completely different, and I have no idea how this one performs (It also comes without the rear camera).

While it's showing the rear camera perhaps it's not been set to record the rear camera. Look through every menu on the camera and if you find one saying something along the lines of Record A&B, just A or Just B, then change to A&B or Front & Back etc

My car got keyed scratches on sides badly when parked. I'd like to install a car camera that would help me to catch the vandals. I've searched and watched your reviews on front and rear cameras, but could not find one that is for the sides of the car.
Would you please recommend some good cameras for solution to catch vandal who scratches the car when parking. The cameras that do the good job but at a reasonable prices and easy to install.

Much appreciated.

Hi Alex,
I have a similar question on here somewhere.

I'm no expert, but I think you will need a separate dvr (plenty of these about) wired to 'always live'.
My problem is, that I can't find small cameras to insert into the inside of my door panels.

I want a camera in the drivers door, looking across to the passenger door/window, and one in the passenger door, looking across to the drivers door/window.

There must be tiny cameras around, as they use them in phones, computers etc.

In the meantime, I bought a ScanFX R300, which I'd like advice on if anyone can help.

I'll be following this - good luck Alex.

My camera cant even turned on just for 10 sec even the battery is fully charged.

November 27, 2015 | Unregistered CommenterMax

I now realised that the rear camera uses a lot of the battery. The rear camera has infrared led on it but it cant be deactivated. When the power is cut out, the camera will die in a few seconds and the last clip will be corrupted. When the rear camera is not plugged in, it works just fine but l want to use the rear camera as well. .

In my experience this type of DVRs are crap, won't survive more then one year of use.
Too many issues, power supply issues,internal battery issues, buggy settings etc..
I think the way to go is the industrial type DVR's .. Yeah they are more coplicated to install, but the are way more reliable.
I have installed now ,I don't know who makes them ,but I'm quite happy with it. Moreover it's a four cam DVR and I have 360 degrees covered. ;)

In reply to Mike's comment (February 29, 2016) re them being crap. You get what you pay for is I suppose the correct response.
All I know is the one I fitted in my car is now approaching it's 4th year in situ; without a problem
For the £35 or so it cost anything over a year is a bonus, so I am well pleased
Maybe when this one dies I will look at a better/dearer model, as whilst I appreciate the merits of the 360 coverage, at the moment I'm just not convinced

Hi Guys, I have two of these 'crash' cams. One works ok (up to a point) and can be used 'almost' normally, but the other camera saves only the last loop on the 16GB card. I assume that the camera is over-recording all loops, instead of beginning to over-record once the card is full. I've read all the posts in this forum, but have not seen anyone mention this problem . . . does anyone have any ideas? Thanks, Tony

Mr. Techmoan,

I bought a car dvr with a wired rear camera. It works fine, but has one big fault. The battery is either not installed or is non functional. So every time I unplug it the date/time stamp reverts to the default setting. Do you know if there is a way to replace the battery?
Also is it possible, do you think to wire the power cable directly to the fuse box?
I have emailed the seller but have to date received no reply. Looking forward to your reply!
Your video's are really great and did " what it says on the tin" they were instrumental in helping me choose the dvd I bought.
Thanks Niels Baadsgaard

You can buy an adapter on ebay which can be connected to the fuse box. Actually wired mine to the glove box light switch which is only live when the key is switched on. The adaptoer has an inline fuse for protection.
