Wisenet Wave - Failover

Fail-over is a feature in WAVE which allows servers to automatically recover cameras to another merged server when there is a power failure or network disruptions. Fail-over must be enabled on individual Servers to be automated. When enabled, the failover process takes approximately 1 minute to activate in the instance. 

To Enable Automatic Camera Fail-over on a Server:

  • Right-click on your Server name and choose Server Settings
  • In the Server Settings dialog, check Enable Failover
  • Enter the maximum number of the selected server that can handle (128 Maximum on Core i3 or above CPUs, 12 maximum on ARM CPUs)
  • If you want to add additional Failover Servers in the same System, repeat the steps above for each Server

To Setup Failover Priority

  • While in the Server Settings dialog, click Fail-over Priority
  • Assign a value of High, Medium, or Low priority to a specific camera
    • High – these cameras will be failed over at first.
    • Medium and Low – these cameras will be failed over only if there is a server to host them.
    • Never – these cameras won't be failed over.
  • Repeat this for all cameras that should be prioritized

In a failover environment, two or more servers must be merged and each server will need enough payload to also handle the failed cameras since a Wave server takes a maximum load of 128 cameras. 

In this case, adding more servers to a merged system or a to the hive will reserve more space for failed cameras on each server. The archived playback will remain seamless but there may be a 30-second gap in recording during the transfer.

*** To be able to do failover, both servers should be able to access devices.
