(Edge Storage) How to set up on-camera storage for AXIS cameras for recording redundancy

On-camera storage for AXIS cameras provides video recording redundancy.

To support on-camera storage you need Firmware 5.40.  Cameras that currently support 5.40 are listed here: http://www.axis.com/techsup/firmware.php

  • Symphony automatically detects if an AXIS camera supports this and has been configured for on-camera storage.
  • In the Timeline, a contrasting green bar (magnified in the following figure) indicates that video has been downloaded from on-camera storage because tracker had crashed or restarted or the video stream from the camera had been lost.

green bar

Important: Symphony does not analyze video downloaded from the Axis camera. As such, it does not determine activity type, for example, broken rule or video signal lost.

To see visual confirmation in Symphony that video has in fact been downloaded from the on-camera storage:

  • Set up the Axis camera in Symphony to Record Video Always. (Server Configuration dialog box, Devices panel, Video tab.)

record video always

Symphony will then display the contrasting green bar in the Timeline when video has been downloaded from on-camera storage.

  • If Record Video is set to other options (Schedule, Pixel Changes Detected by PC, Motion Detected by Camera, Schedule & Motion Detected by Camera, or Never), you can click historical instances of the Timeline to retrieve images and video from the on-camera storage (SD Card or local NAS) while the camera is running and the edge storage device is configured and connected. Note that this footage you access is NOT saved to the Symphony server. It is downloaded from the AXIS camera’s SD card each time.

Set up on-camera storage for Axis cameras

  1. Add the Axis camera to Symphony.
  2. Access the camera web page to configure it:
    1. Click Setup > System Options > Date & Time.
      1. Select Time zone. Camera must be in same time zone as the server.
      2. Select the Automatically adjust for daylight saving check box.
      3. Click Save.
    2. Click Setup > Recordings > Continuous.
      1. Select the Enable check box.
      2. From Disk drop-down list, select SD card.
      3. From Stream profile, select AS0x1.
      4. Click Save.

      4. Click Save.

Notes related to Symphony:

  • Historical video playback from SD Card on Axis Camera is at recorded FPS. Therefore, the speed slider in Symphony Client will not work.
  • If on-camera storage (edge storage) is not working during setup, restart the AI NetSendHist service on the Symphony server.

Notes related to Axis Cameras:

To support on-camera storage you need Firmware 5.40.  Cameras that currently support 5.40 are listed here:http://www.axis.com/techsup/firmware.php

Axis recommends using only high performance SD cards and formatting cards to EXT4 which is not readable from Windows machines. To ensure that edge storage can transfer back to AVMS, additionally format the SD card to VFAT.

When downloading live or recorded video from the SD card, FPS can drop below the full FPS (25 fps in 1080p) for 3MP, 5MP, or ARTPEC 4 chip-based Axis cameras.

To format the SD card on the camera:

  1. Access the camera web page.
  2. Click Setup > System Options > Storage.
  3. Select the SD card and click Format.

For more information, see: http://www.axis.com/partner_pages/development_news.php?t=cv&mid=2562

To record to the SD Card only when no network connection is available:

  1. Access the camera web page.
  2. Click Setup > Events > Action Rules.
  3. Click Add.
  4. Select the Enable rule option.
  5. Specify Trigger Conditions as Hardware, Network, Any, and Is lost = yes.
  6. Specify Actions as: Record Video, select Stream profile, select Duration options, and Storage = SD Card.
  7. Click OK.
