Open the Storage on External File Server / Flash Device dialog to set the camera's storage options.
The camera can store images in a ring buffer that is located either internally in its RAM, on a Flash device or on an external file server. A ring buffer will overwrite its oldest images once the storage capacity has been reached. Storing images on a file server is accomplished without installing any additional software on the file server.
This strategy for external recording is very powerful, thanks to the low network loads and the integrated image buffer of the camera, which can also bridge short network failures. It is thus no problem at all to record the events of 30 cameras on a regular Windows computer (P4 / 3 GHz).
When recording to Flash devices, they can be internal storage media (e.g. M15, M25M, T25M, D15 or S15, except Web and Basic models) or you can connect external devices (e.g. USB keydrives, Flash SSDs or USB harddisks) to the camera.
Notes:
The camera can record the video sequences with audio on different Primary Targets (Flash devices, USB harddisks or file servers) without installing any software. You can choose between the following primary recording targets:
Notes:
Caution! |
The camera will automatically create a folder structure in the specified folder on the recording target, which is based on its factory IP address (dots are replaced by underscore characters). This path contains the audio and video data as well as various other files, which are required for the proper management and playback of the stored video data on the recording target. Make sure that the camera paths and their contents cannot be changed in any way by assigning corresponding rights on the storage folder. |

When recording on Linux/UNIX file servers, the camera uses NFS (Network File System) and stores the video in a directory on the server (commonly entered in /etc/exports
), which is mounted as a file system.
Note: The server configuration may vary for different distributions. Note that MOBOTIX cannot provide support for configuring the Linux/Unix server.
Log onto the file server as root user.
Create a new directory (e.g. mxdata
):
mkdir /mxdata
Change the owner and the user group for this directory:
chown -R 65534:0 /mxdata
Assign the required access rights for the directory:
chmod 755 /mxdata
Use the ps aux | grep nfs
command to check if the NFS server is already running. If this is not the case, use the /etc/init.d/nfsserver start
command to start the service, or install the service from scratch, if it is not available.
Use the rpcinfo -p
command to check if the nfs, mountd and portmapper services are executed. Normally, nfs and mountd are started by the NFS server while portmapper is executed as a separate service. If portmapper is not executed, you can start it using the /etc/init.d/portmapper start
command.
Open the /etc/exports file in a text editor and enter the following line:
/mxdata 192.168.1.15(rw,no_root_squash)
To re-initialize the list of entries in /etc/exports, execute the exportfs -a
command.
Next, restart the NFS server. Execute the /etc/init.d/nfsserver restart
command.
This completes the configuration of the Linux/UNIX server.

When recording on Windows computers, the camera uses a Windows share on a Windows 2000 Professional SP 2 system or higher. You can use not only products of the Windows server family, but also Windows Professional products; note, that the number of parallel connections serviced by such a workstation is limited, however.
Notes:
Note: The configuration steps may be different depending on the version of the Windows operating system. If this is the case, follow the steps that are relevant for your Windows version (2000/XP/Vista/7/8).

If this storage option is available on your camera, the Storage on External File Server / Flash Device dialog (Storage Target > Primary Target section) allows using Flash devices (USB Stick/Flash SSD, External USB Harddisk or SD Flash Card) as storage media for events.
The MxFFS file system (short for MOBOTIX Flash File System) has been designed for professional applications that are requiring safe storage and which are creating high throughput over longer periods of time. This recording format has been developed with the following two properties, which are a prerequisite for security applications:
You can use formatting to prepare recording targets (USB Stick/Flash SSD, External USB Harddisk, SD Flash Card) that have not been used in a camera, for storing the camera's recordings. Likewise, you can use this function to securely erase storage media that are not used any more. This will make restoring the deleted data impossible (see Secure deletion mode - slow below).
Note: If you would also like to use the SD card for recording MxAnalytics data (not available on all camera models), you should proceed as described on the corresponding help page in the MxAnalytics Data Storage section.
Hint: You can leave this help page open during the entire process to properly follow the step-by-step instructions.
Proceed as follows to format a recording target:
Caution: Only activate the Secure deletion mode - slow option if you would like to erase any existing data without having a chance to recover them. This formatting mode can take up to a couple of hours, depending on the size of the device.
When recording to a Flash medium, you can simultaneously archive the MxFFS video data on an NFS or SMB/CIFS file server. Besides acting as the primary storage target, the Flash medium also serves as a temporary storage if the camera detects network or file server problems.
In the Storage Target section, select one of the NFS File Server or SMB/CIFS File Server options as MxFFS Archive Target. Configure the corresponding parameters in the MxFFS Archive Options section.
Parameter | Description |
---|---|
MxFFS Archive Size | Set the storage space that the camera should use for the archive. |
Archive Timetable |
Select a timetable to control archiving based on a weekly schedule. Select the timetable in which you have specified the timeframes for archiving. The timeframes only control when writing to the archive takes place. Reading from the archive is possible with both active or inactive archiving. |
Archive Retrieval | When trying to retrieve recordings that are not present on the Flash medium any more, the camera can read the corresponding video data from the archive. Please note, however, that this creates additional network traffic, which may use up the entire bandwidth, even though archiving alone would be possible. Use this setting to control whether or not the camera should be allowed to read from the archive. |
The Storage Limits section contains the different types of limits that are available for the selected primary target. Defining sensible limits will prevent the storage space for the selected primary target from running out, which would prompt the camera to stop storing recordings on this target.
Warning: Make sure that all cameras combined do not use more than 90% of the storage space on the file server. Hence, you should make sure that you are distributing the available storage space between the cameras that are storing on the target (i.e., by setting a sensible Storage Size).
Note: The options in this section will change depending on the selected Primary Target and which MxFFS Achive Target has been chosen in the Storage Target section.
Parameter | Description |
---|---|
Time to Keep |
Deactivate the Unlimited option and enter the desired maximum values in one or more of the text fields. Note: If one of the defined values has been reached, the camera will automatically delete the oldest recordings (ring buffer storage). |
Storage size |
Deactivate the 4TB Limit option and enter the maximum storage size in the text field. Note: If the reserved storage space has been reached, the camera will automatically delete the oldest recordings (ring buffer storage). |
Reserve Storage |
If the Storage Size parameter has been set, the camera uses the reserve storage if the file server is running under high load and the camera cannot store the data as quickly as needed. In this case, the camera temporarily increases the storage size by the amount of the reserve storage to be able to transfer the files as quickly as possible. Time-consuming operations are postponed (i.e. deleting old files). The camera will run these operations once the server load drops to normal levels again. |
Number of sequences |
Deactivate the Unlimited option and enter the maximum number of video sequences to be stored in the text field. Note: If the defined number of sequences has been reached, the camera will automatically delete the oldest recordings (ring buffer storage). |
Activate the options in the External Logging section (only shown if you clicked the More button) to periodically copy the log files for external recording as well as the camera's Web Server Logfile and System Messages to the file server.
To test the camera's external ring buffer on a file server, do the following:
connected to file server 192.168.x.x:/mxcam
.
In order to remedy errors that are occurring, you should activate the options in the External Logging section and check the Event Storage Logfile (Logfile link in the explanation of this parameter). (This link is only visible if the recording to an external file server or Flash device has been set up successfully.)
You should also configure the Storage Failure Detection to use the messaging options of that dialog to alert you of problems with recording to file servers or Flash devices.
