Lots of information about Memory cards…

Memory cards are a very important factor of the Mobius functioning properly and have been a large source of issues. It should be noted that not all micro SD cards are created equal; just like anything else there can be fakes and performance differences. For over 3 yrs we have only been selling Kingston Class4 cards, and have had virtually no problems or issues. Class4 memory cards are all that is required for the Mobius to function properly, Class6-10 cards do nothing for performance and are likely to cost you more money.

A Statement about Memory Cards: Please advise card details used in your camera. We sometimes suspect it might be a fake Volume-Expended card, for example, it is actually only 4GB, but is stated as bigger, like 8GB, 16GB, or even 32GB, you may not find it by checking it on computer, or even by some card test tools. You will have to try to copy actual files on it. We have a fake card for testing, it claims to be Kingston Class 10, 32GB, the writing speed is less than 2MB and quite unstable. Formatted, computer says it has 32GB, we tried to copy 32GB video files onto the card, computer did not alert any problem, the computer even completed the whole copying process, we clicked the last video file, it played back OK. All the files appeared to be on the card, but when we tried to playback the first file, all went wrong, the file size turned into 0KB / 1KB. We end up only getting it to work for about 4GB of files. When we used it for video recording, the symptoms were; record 5 minute segments properly until the memory card is about half full (~4 gig) and then it will record 1-5 second clips whenever recording is started. (this is the behavior for the camera when it has run out of memory) We have a few different fake cards for testing, and the testing results are unpredictable.

More information about Memory Cards: In general you may use any micro SD, micro SDHC or Micro SDXC card with a capacity of up to 128GB with this camera. Larger cards are most likely also supported but not yet available. To avoid card compatibility problems, always use quality cards with a speed rating of Class 4. There are known problems with a few cards that have a higher class rating, for example some, but not all, Sandisk 32GB Ultra (class 10) will not work properly with earlier firmware versions. You should use firmware v1.17 or above with these cards. For the best compatibility use cards with a class 4 rating if you have them. There is absolutely no advantage in using cards with a higher rating. The most compatible cards are genuine Kingston. At the time of writing there are known problems with some 64GB cards when formatted with exFAT. For this reason it is recommended to format 64GB cards with FAT32. 128GB cards will also work but cannot be correctly formatted to FAT32 using the built-in formatting routine (as of firmware v2.18).

Most firmware versions support cards formatted with FAT, FAT32 or exFAT but v2.03 – v2.10 only support FAT and FAT32. Firmware v2.18 and above support both FAT32 and exFAT. Cards with a capacity of 64GB and greater must be formatted using the In-Camera formatting routine (see below) if they are to be used with firmware v2.03 – v2.10.

It is recommended to only use FAT32 when loop-recording is enabled (the file with the lowest sequence number will be erased when there is no more disk space available for the new recording).

Due to technical reasons you cannot update the firmware if your card is formatted as exFAT. The In-Camera formatting routine (see below) will format cards to the format required by the firmware. With firmware versions up to v2.03 the routine will format cards with a capacity greater than 32GB to exFAT. All other cards will be formatted as FAT/FAT32. Firmware v2.18 and above allows the user to set which type of formatting will be used with 64GB cards and above, but remember to always set the parameter to exFAT if you wish to in-camera format 128GB cards. Older operating systems, for example XP 64-Bit and Windows 2003, do not support exFAT file systems unless you install additional drivers.

There are a few programs available, for example guiformat, that are capable of formatting large capacity cards with FAT32. With a Mac it is no problem to select FAT32 with the standard Disk Utility.

You should always use cards from well known brands. Low quality and no-name cards, as well as some class 2 (or less) cards, may draw more than 20mA current than quality cards. This can result in unwanted electrical noise such as clicks, chirps, hum and buzzing in the audio recording. Fast cards, class 10 and above, even from well-know brands can also produce unwanted electrical noise so should be avoided.

►The following approx. recording times for 1080p videos with a standard data rate are as follows: 32GB Card = 4 hours 30 mins., 16GB Card = 2 hours 15 mins., 8GB Card = 1 hour 7 mins., 4GB Card = 33 mins.

►This manual assumes a compatible SD card is inserted in the card slot (except for WebCam mode).

The card must be carefully inserted face down with the gold contacts upwards and facing forward. Do not use force or you could damage the lock mechanism inside the card holder.

Memory Card Formatting Information: Standard formatting tools provided by the operating system are not always reliable. Also, they do not optimize the SD card’s performance. For optimal card performance it is recommended to always use the camera’s built-in formatter. Instructions for In-Camera Formatting are outlined below under “In-Camera Formatting”. Another excellent formatting utility is “SD Formatter” which can be downloaded from This utility has been specifically designed for formatting SD cards but will always format 64GB and greater cards to exFAT. Firmware v2.03 – v2.10 requires all cards be formatted to FAT32 so 64GB/128GB cards must be in-camera formatted (see below).

In-Camera Formatting: The Camera contains a built-in formatter which may be used to format the SD card. In-Camera formatting is best done using mSetup.exe (see below) but can also be done as follows:

  • Connect the camera to an External USB power supply or to a PC as a Removable disk (see above).
  • Press and hold down the Mode button. DO NOT RELEASE the button until after the next steps are completed.
  • Disconnect the camera from the power supply or the computer.
  • The yellow LED will blink for a few seconds followed by three blinks of the red LED, after which the camera will turn off. You must wait until you see the red LED blink three times.
  • Release the Mode button.

►In firmware versions up to v2.03 cards with a capacity greater than 32GB will be formatted with exFAT. All other cards will be formatted as FAT32. See the note about using exFAT in older operating systems in the Cards section, above.

Check the integrity of your Memory Card: by using the program h2testw to make sure your card is genuine and not a fake card that has been up-rated. Example h2testw results for a Kingston Class4 Card.


The other thing you could try if you don’t have another memory card is to run H2testw program to test the card. Link to test software is here:
1) Open H2testw test program
2) Select “English”
3) Select “Target”
4) Navigate to computer drive letter of camera, i.e. (G:)
5) Under Data Volume, select “Only” and enter 500 in the MByte box
6) Select “Write + Verify” button to run test on card.
7) Select “Ok” to warning dialog box that appears.
8) Testing will begin. Test will take a few minutes to test this small amount of memory
If test completes and says card passes, then most likely the card is ok, If test says “The media is most likely defective” then this card will not work in camera…

Again, many times these failed cards appear to be fine when just dragging and dropping files using standard file manager routines. The problem is they are too slow and can not keep up during the writing of HD video files.


We should always avoid any unreasonably cheap cards and always get memory cards from reliable sources.

Taking Time Lapse Photos using a Transmitter: when using the Mobius to transmit photos, it is best to set the “Time Lapse Photo” setting to; one photo every 2 seconds in the configuration utility. Setting this at anything less creates some very undesirable effects in the pictures. (Thanks to user Dave for submitting this info)


  • Unless there is a feature/enhancement that you really need, and your camera is functioning properly,  it is recommended to not update the firmware, esspecially as soon as it is released. (let some time pass to see if there are any issues). However, it should also be noted that you can go backwards in firmware versions.
