Storage Failure Detection

Use the Storage Failure Detection dialog to configure tests that constantly monitor the external recording target (file server or Flash device) that the camera is using as an external ring buffer. The camera will actively monitor its recording 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.

Note: 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 recording target or if events have been lost. Depending on the selected sensitivity, the tests can be executed with different strictness.

Description of Parameters

Parameter Description
Check This option enables or disables the camera's storage failure detection.
Note: If storage failure detection has been activated for the first time after the last reboot, make sure you restart the camera!
Tests 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 recording target.
  • Lost events checks if the most recent events have been written properly to the recording 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 recording target).

Note: Rebooting the camera will delete the log file contents.
Sensitivity 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.
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.

Notification

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 e-mail or an IP Notify message. If the camera is connected to ISDN, 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

Parameter Description
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.
FTP Select the FTP Profile that should be used to transfer images in case of an error condition.
Note: The FTP server and the external file server of the camera should not be on the same computer, if possible.
E-Mail Select the E-Mail Profile that should be used for sending the error messages.
Note: In order to obtain more information on the error condition, set up the e-mail profile to append an image or the system messages.
Phone Call If the camera is connected to ISDN or 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.
Note: If ISDN data dial-out has been configured and the camera remote control has been activated in the phone profile, you can use the remote control features of the camera to establish a dial-out connection to the Internet. This will allow you to search for errors using the browser remote controls.
IP Receive Select the IP Notify Profile that should be used to send error messages in case an error condition has been detected.

Storing the Configuration

Click on the Set button to activate your settings and to save them until the next reboot of the camera.

Click on the Close button to close the dialog. While closing the dialog, the system checks the entire configuration for changes. If changes are detected, you will be asked if you would like to store the entire configuration permanently.
