What is Automatic Camera Fail-over?
Automatic Camera Failover is a feature in Nx Witness which allows System Servers to automatically recover when a power or networking failure occurs on a Server. Automatic Camera Failover can be enabled on individual Servers. When enabled Failover tells the server to grab cameras from any failed Server in the System.
A single Server can handle a maximum of 128 cameras. So, for example, if a Server is actively recording 64 cameras it can act as a Failover Server for up to 64 additional cameras from other Servers in the System.
Failover takes approximately 1 minute in the instance of a network or power failure.
To Enable Automatic Camera Fail-over on a Server:
- Right click no a server in the Resource Panel and choose Server Settings.
- In the Server Settings dialog check Enable Failover.
- Enter the maximum number of selected server can handle (128 Maximum on Core i3 or above CPUs, 12 maximum on ARM CPUs)
- Click OK.
- If you want to add additional Failover Servers in the same System repeat the steps above for each Server.
To Setup Failover Priority:
- While still in the Server Settings dialog Click on the Failover Priority button.
- Assign a value of High, Medium, or Low priority to each camera.
- Failover for System cameras will follow assigned priorities - with High priority cameras failing over first, then Medium priority, and finally Low. Failover assigns cameras to the first available Failover server recognized by the System.
- Repeat this for all cameras that should be prioritized.
