  3. Select start and end time and date for the export. Alternatively, use the timeline slider to chose the export duration. If multiple camera nodes are in the video wall, select the camera from the dropdown and click export. If there is only a single camera node, click export.

Export Video from Camera > Video Page

  1. Navigate to Cameras > Monitor > Cameras

  2. Select the desired camera from the camera list.

  3. On the Video tab, click Share > Export

    • Note that for the fisheye camera, you can export in both the warped (circular) and dewarped views.

  4. Select start and end time and date for the export. Alternatively, use the timeline slider to chose the export duration.

  5. Click Export to start the export.

Note: The current minimum time allowed for a single export is 5 seconds and maximum time allowed for a single export is one hour. Video exports are trimmed to the requested size with no buffer. If an invalid time range is selected, the export will automatically default back to 30 seconds to provide a valid export. The download link for an export is good for one hour at time of page load. Refreshing the dashboard page generates a new download link. 

Exports Checksum

You can verify the integrity of a video clip by saving a copy of the original export's calculated SHA-256 checksum provided on the dashboard and referring to it every time you need to compare a copy to the original. A SHA-256 checksum is a 256-bit or 32-byte hash serves as the file's "signature", and can be calculated over and over again to the same result. However, once the file is changed in any way, this value becomes different. It is generated using the SHA-256 secure hash algorithm. The algorithm is a one-way function, it cannot be decrypted back. 

 

  1. You can find out what the video checksum is by clicking on the export under Recent Exports and then Calculate checksum.
  2. The 256-bit checksum will be printed underneath. Take a screenshot or copy-paste to save this in a safe place.Screen Shot 2019-04-01 at 9.56.05 AM.png
  3. Every time you want to verify that any copy of the exported video is legitimate, you can calculate this copy's checksum and compare it to the one provided on the dashboard. If they match, the video is identical. Otherwise, it has been corrupted or tampered with.
    • To calculate the SHA-256 of a downloaded file, you can use a terminal. We provide the instructions for Windows, Mac or Linux below.
      • Windows Power Shell
        • Get-FileHash -Algorithm SHA256 .\Filename.mp4
      • Linux
        • sha256 .\Filename.mp4
      • Mac OS Terminal
        • shasum -a 256 .\Filename.mp4

Exports Retention Period

By default, an export will be stored for 30 days in the Meraki cloud ecosystem. If a max retention time is set on a node, the export retention period will respect that value.

 

Note: If a firewall is in place, it must allow outgoing connections on particular ports to particular IP addresses. This is due to MV export functionality requiring connectivity to the Cisco Meraki cloud infrastructure. The most current list of outbound ports and IP addresses for your particular organization can be found here.

 

Video stream

You can share a video link for stored video by navigating to either the video wall or the camera status page and clicking on Share > Share link.
