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.
