Storage Failure Detection

Use the Storage Failure Detection dialog to configure tests that constantly monitor the external storage target (file server or Flash device) that the camera is using as an external ring buffer. The camera will actively monitor its storage target and reports problems with video recording using the notification methods specified in this dialog.

Before you configure the storage failure detection, make sure that you have properly configured the options in the Storage on External File Server / Flash Device dialog.


This feature is not available for Web and Basic models.

Configuring the Tests

You can choose to run different test methods. The camera can check if the file server can be reached on the network. It can also test if all event images have been transferred properly to the storage target or if events have been lost. Depending on the selected sensitivity, the tests can be executed with different strictness.

Description of Parameters




This option enables or disables the camera's storage failure detection.


If storage failure detection has been activated for the first time after the last reboot, make sure you restart the camera!


Select the tests you would like to perform.

  • Ping test checks if a file server responds to network packets (do not use this option if you are recording to Flash media.

  • Check transfer checks if it is possible to write data to the storage target.

  • Lost events checks if the most recent events have been written properly to the storage target.

If the storage failure detection is running, the dialog shows a link to the log file. The log file contains messages (error and success messages) and measurement values (transfer buffer usage, number of the last event stored internally and transferred to the storage target).


Rebooting the camera will delete the log file contents.


Select the sensitivity of the tests. Selecting High will use stricter test criteria and will notify you early if problems occur. Selecting Low will use less strict test settings and notification will be delayed. If Sensitivity has been set to High, the camera triggers an alert if the remaining storage capacity has dropped to 45 minutes. Selecting Low will only trigger an alert if the remaining storage capacity has reached 15 minutes.

Add the fsck_archbuftimelimit=n configuration parameter in the camerachecks section of the configuration file in order to set a different remaining storage capacity (in n minutes).

Startup Delay

Activate this option and select a value to delay the start of storage failure detection after a camera reboot. This allows adjusting a nightly camera reboot to a reboot of a NAS system used for recording, for example.


In order to notify you of any problems that the file server may be having, you can let the camera transfer an image to an FTP server or have it send the error message using an email or an IP Notify message. If VoIP telephony has been set up for this camera, it can also call you on the phone to let you know that an error condition has been detected. The camera itself can use its speaker to play an audio message or it can activate its LEDs to alert you of an error condition.

Moreover, you can set an interval to repeat the error notification until the error condition has been removed.

Description of Parameters



Camera LEDs

The camera can signal an error condition by flashing the LEDs on the camera front. Select how the LEDs should blink: Blink one LED or Flash all LEDs.

Audio Message

Select the Audio Message that should be played back on the camera speaker.


Select the FTP Profile that should be used to transfer images in case of an error condition.


The FTP server and the external file server of the camera should not be on the same computer, if possible.


Select the Email Profile that should be used for sending the error messages.


In order to obtain more information on the error condition, set up the email profile to append an image or the system messages.

Phone Call

If VoIP has been configured, you can select one of the profiles defined in the Phone Profiles dialog and the camera will call you in case of an error condition.

Network Message

Select the IP Notify Profile that should be used to send error messages in case an error condition has been detected.
