Mobotix D24M-SEC Network Camera – Flash Memory Upgrade

I explained the camera network configuration in this prior installment.

This tutorial explains how to upgrade the Mobotix D24M-SEC camera flash memory card. The camera has a factory installed 4GB microSDHC flash memory card that is easily replaced with up to a 32GB flash memory card.


Why upgrade the flash memory? Because the flash memory is where the camera images are stored for later playback or download. Images are written to the flash memory in a circular fashion (first in / last out), with the newest images overwriting the oldest images in a never ending cycle.

More memory means you can:

  • Increase the on-board Digital Video Recorder (DVR) capacity.
  • Record at faster frame rates (frames per second) for longer periods of time before over writing older images.
  • Record longer at full QXGA 2048 x 1536 (or any lower) resolution before overwriting older images.
  • Not worry so much about losing valuable video. For example, if you notice something was stolen or vandalized a day or two after the fact, the video images and event history would still be held in flash memory for examination. (There are other options to help here, such as transferring images to a FTP- or web server for long term storage.)

Mobotix D24M Flash Memory Upgrade Procedure

The microSDHC memory card is located on camera circuit board as indicated by the yellow square in the photo below.  MicroSD memory cards are really small, about the size of your finger nail.

When choosing a new microSDHC card for your camera upgrade, I recommend a “Class 6″ or better speed rating. MicroSD cards are available in several speed classes, which are:

  • Class 2: 16 Mbit/s (2 MB/s)
  • Class 4: 32 Mbit/s (4 MB/s)
  • Class 6: 48 Mbit/s (6 MB/s)
  • Class 10: 80 Mbit/s (10 MB/s)

A faster card means the camera CPU won’t be slowed down while waiting to write images to the flash memory. Faster speed ratings also mean more expensive. Don’t be fooled by buying a 16GB Class 2 card because it’s cheaper than the 16GB Class 6 item – read the fine print. I chose the Class 6 card as a compromise between cost and performance.

Replacing the flash card is easy:

  • Power-off the camera.
  • Press down on the exposed edge of memory card to release the locking spring mechanism.
  • Pull the old card out – notice the card orientation.
  • Insert the new card – it’s keyed and only goes in one way – and press down until it clicks and locks in place.

Power-on the camera by connecting the Ethernet cable to a PoE switch port.

Formatting the New Flash Memory Card

The new memory card must be formatted by the Mobotix camera software before use. To reformat the newly installed microSDHC card:

  • Log into the camera as “admin”.
  • Click the Admin Menu button on the top left sidebar.
  • Click Image Storage in the Admin dialog.
  • Change the Storage Target option to None and reboot the camera.
  • The camera can rebooted from the Admin Menu or power cycling the camera.

After the camera reboots:

  • Log in as “admin”
  • Click the Admin Menu button.
  • Click Image Storage.
  • Select the SD Flash Card storage target option.
  • Click the Format button to the right of the SD Flash Card check box.
  • Choose Quick Format option and click OK.

Take a break or stare out the window because I found the ‘Quick Format’ took 15 to 20 minutes on a 16GB Class 6 microSDHC memory card.

The “Media Successfully Formatted” dialog will appear when the formatting process is finished.
